General Motors has been slapped with a new class-action lawsuit over alleged issues with the Vortec V8 engine in its GMT900 platform full-size trucks and SUVs.
This lawsuit, which was filed in U.S. District Court in the Northern District of Ohio, is yet another class-action proceeding against GM over alleged oil consumption problems in the Generation IV 5.3L Vortec V8 engine. The automaker is already facing a number of other similar class-action lawsuits over this problem, two of which were filed just this year.
The oil burn problem is allegedly caused by the PCV valve in the engines, which can draw oil out of the valvetrain and into the intake before it is burned in the combustion chambers. This lawsuit also claims the piston rings fail to maintain pressure in the crankcase and that a faulty oil pressure relief valve sprays oil directly at the piston skirts, overloading the rings and allowing oil to sneak past into the combustion chamber
These issues can lead to low oil levels in affected vehicles, the lawsuit says. Severe engine damage can occur if the engine is run with insufficient oil levels, including piston and rod damage, among other issues. The oil leakage can also foul the spark plugs, causing the engine to misfire and/or shut down completely.
GM has implemented various fixes for this issue through Technical Service Bulletins, although the plaintiff in this suit says the automaker’s suggested repairs only temporarily solve the issue.
This lawsuit claims the following GM full-size trucks and SUVs with the 5.3L LC9 Vortec V8 engine are prone to these issues:
- 2010-2014 Chevrolet Silverado
- 2010-2014 Chevrolet Suburban
- 2010-2014 Chevrolet Tahoe
- 2010-2014 Chevrolet Avalanche
- 2010-2014 GMC Sierra
- 2010-2014 GMC Yukon
- 2010-2014 GMC Yukon XL
In early November, a judge tossed out a similar lawsuit that was filed in Ohio back in 2019 after finding multiple problems with the plaintiff’s claims. The judge found GM did not breach its warranty terms and also said the plaintiff in the nationwide suit lacked standing “to assert claims under the laws of the states in which they do not reside.”
We’ll provide an update on this latest oil burn lawsuit against GM when more information becomes available.

IF there is actually a design problem with the 5.3L, driving the vehicle while low on oil is still the negligence of the owner for not checking oil level.
I’m not sure if there is a design flow or not, there seems to be a bunch of evidence that poor maintenance leads to the majority of engine issues. There’s a ton of those engines with 4-500K kms on them around where I’m from.
So engine has design flaw, but the owners negligent for not constantly checking and adding oil when they shouldn’t have to. Hence the lawsuit.
Is it covered under warranty? How do you define a “design flaw”?
A known defect from the manufacturer are not by any means ambulance chasing nor playing tech. Kinda like the 15 cent spring in the cobalt ignition that killed 13 people by fire (burned alive mind you) the manufacturers play the odd hoping that casualties will be low enough so complaints can be mitigated or ignored all together UNLESS safety becomes a issue as far as negligent manufacturing or safety is ignored. I am a 40 master technician and worked for UAW and have seen and signed non disclosure agreements where ( we dont talk about this issue) media or other wise.
How about just making a good vehicle manufactured in the states with us parts to boot so we don’t have to seek lawyers to take care of the issues that created this mess in the First place. Let make America manufacture all the parts with pride or did we loosed that all together
Buy a Ford. They run on all cylinders.
All six.
Heard Ford is doing this nonsense to their 5.0 in 2021.
I don’t like this technology.
I have a 2008 tahoe 5.3 and it is doing the same thing I just got my oil changed 3 weeks ago and it said I was a quart low
Lolol google Ford Class Action…..no they don’t.
Yeah I have a 2013 Sierra it is down right now over these issues how do I get in on this lawsuit who do I contact
That’s why, the class action lawsuits!
Did you read the article? Pretty sure they explained the design flaw. Oil does not seep into the combustion chamber on a normal engine!
If you use covengenal oil it will burn oil. Use synthetic motor oil. No problem. My 03 had 368000 miles on it. No problem. My current 2012 has 18000 miles. No problem. GM requires full synthetic oil.
2003 didn’t have AFM. That didn’t start until 2007. That’s when the problems started on these motors
2013 Silverado 5.3– As soon as I had the AFM turned off (at 93k miles) my oil consumption quit. I have 215K miles on it now and not a drop.
My last one,2012 Silverado 5.3–had 130k on it, no oil consumption but I pressed the gas to pass someone, the AFM kicked off, the valve stuck open, 4500.00 later I have the engine rebuilt by GM. I’m burning oil like crazy. After lots of research, I had the AFM turned off. No oil consumption, no worries about the damn valve sticking open. I lost 1mpg keeping it in V8 all the time.
Hi,
How did you cancel the AFM? Thank you.
I have a 2009 GMC Sierra that is giving me the same problems. I did all the fixes on the vehicle bulletin but it still burns around 2qts of oil between oil changes. Doesn’t help that GMC dealerships and mechanics play dumb or are dumb! I am the original owner but I don’t plan on buying another GM truck in my future.
Sold my Sierra- dealer had torn engine down and added shields in crankcase and valve covers to prevent splashed oil from being pulled into cylinders that were turned off by auto fuel management (no combustion in cylinder creating suction) If I still had truck would have AFM software disabled
Should have purchased the Range Tech, AFM eliminater plug in. $200.00. It turns ALL that krap off!
All you have to do is drive in M5. It’s disabled.
I don’t see the word “constantly” anywhere in his comment.
Motorists who were taught right know to check the oil every now and then. I do so about once a month (I am now a low-mileage driver), or, if on a road trip, every couple of days. It hasn’t really been necessary in many years, but situations like with the Chevy V8s indicate it is still a good idea.
Classic case of the idiousy of “ambulance chasers” trying to play engine techs. This should never even got to a courthouse door, much less filed. I can sit here and debunk almost if not all of these claims as bogus. Hope the judge is blessed with the defense being of the auto tech field to advise.
I have 07 Escalade and a 07 avalanche plus an 02 avalanche all do the same oil low b4 oil change require
I have a 2002, always a quart low on oil, 5.3 ! Before change oil comes on!
I’ve owned several Chevys iwth V8s over the years. The ONLY one that took any oil at all was a 2001 Silverado with the odd-ball 4.8 litre fleet engine. One quart every 3,000 miles or so. It did it from day one through when I sold it with 128,000 on the clock.
AfM system is causing the oil consumption and the lifters failure on this vortex engines . Not all have the Afm system the ones that dont have it are ok
Yes . The engines without AFM, run just nice. The AFM engines are no good, if the AFM is still are active. Just get the Range Tech. AFM eliminater plug in. It works!!!!!!!!!
I have a 2008 Silverado where the o ring seal for the pick up tube in the oil pan went bad and it took me almost 12hrs to replace it. G M knows about this problem and did not send anything out about it. Good thing I know how to work on it. But i think GM should do something about it. Not to make it a so called silent recall.
Also replaced the left side valve cover because the built in PVC valve has issues. Mine smoked big time every time I started it up when it was cold. Another G M mistake
Wanda is this the same propblem they had with the equinox
Is not owner responsibility to add gallons of oil between oil change
First off your thinking is flawed. You can’t assume the issues are do to poor maintenance by the owner. The major problem stems from the rings GM bought from a particular vendor and used. The vehicles getting 300-500 miles on the motor did not get the faulty rings. Next, this issue started in 2008. I have a 2008 Suburban. We did everything GM recommended, actually what folks had gone through and showed on the internet and then I checked with GM. GM hid the issues. Nothing solved the problem. I’ve never owned a vehicle that I have to put multiple courts of oil in it between oil changes, thus the second flaw in your thought process. I finally had to put a new motor in the vehicle that cost me $6,000.00. GM has been well aware of the design flaws with this motor, but chooses not to resolve the issues. I would be very hard pressed to ever by a GM product again as they do not support their customers or their product.
100% correct. GM laughed at us when we took our 2012 Tahoe in. The lifters sounded like they were about come throught the hood. Told us we used the wrong oil. Just like they did to poor souls in the late ’70’s, early ’80’s over bad cam shafts. They finnaly (GM) got taken to the cleaners after a class action, took them on. Now they are giving owners every excuse in the book. It’s very poor design!!!! They tried to get a better “CAFE” average by doing stupid krap like AFM. Now they are doing “Stop & Start”. Another stupid idea. At least this time, owners can turn it off. But you have to do it EVERY time you get in the vehicles. They just need to stop this stuff. Build great gas milage engines. And stop making customers pay for engineering flaws.
Curious how does someone sign up for the lawsuit, I just spent 3904 to fix the issue.
Are you kidding me?
Regular oil changes at 3-4K miles using synthetic oil on mine and it uses 6 quarts between changes. Yep it has low oil pressure. That’s my fault😂
Yes, one should check their oil I agree. However, technology is suppose to save us from human errors/shortfalls. Not sure on these trucks but I found out by asking the Corvette DOES not have a sensor if the oil is low. My 2000 MB SLK and 2012 Audi TT had this – meaning at about a quart low an low oil light will show up. Seems silly not to have this when oil is so important.
It’s hard to argue running out of oil is GM’s fault when they have a dipstick in which to monitor your oil level.
Check when you fill up with fuel used to be standard protocol. That being said, modern engines don’t usually burn any oil, so we are all in the habit of not check very often, so it is also ridiculous that GM waited so long to add an oil level sensor.
Interesting, as my 2000 Silverado W/T base model with a V-6 has an oil level sensor screwed into the side of the oil pan!
How about those stupid lifters that pop and leave it in 4cyl mode
Agreed. Our 2012 Tahoe LTZ had just that problem. GM laughed at us. Told us it was not enough oil changes, BS. I researched it, and found we were not alone. Found the RANGE plugin. $200.00, but it works like a dream. No more dropping to 4 cylinders, ever again. Try it, it’s really!
If honda can put a low oil sensor on a generator, why can’t GM on a truck???
Sensors false all the time, particularly when the oil gets heavily aerated or foams (the antifoam additive doesn’t work, or the oil picks up silicone from new or repaired seals). Therefore low oil sensors are likely heavily damped, they will only trigger when the oil is almost dangerously low, and then only after a certain number of cold starts or idle times.
For a performance vehicle like the Corvette, the sensors couldn’t be made to work reliably before engine damage occurs, so it’s best not to put one in.
Not true at all, sure its ‘possible’ for the sensors to work unreliably if… if… if…all this certain criteria is met. That doesnt mean 90% of the vehicles don’t perform accurately. If the imports ive owned back in the 80’s and 90’s could have a working low oil level sensor than a bloody 100 thousand dollar frickin corvette can have one too. Its not a matter of cant, its dont want too. Typical GM!
The LT1 in my 95 Caprice has an oil level sensor which still works fine 25 years later, despite my use of fancy synthetic oil. It was just a simple float. I’m pretty sure GM used the same oil pan and sensor in the Corvette that year. 😉
I can say with personal experience 2006 Silverado’s have a low oil sensor, I would think these would as well.
Complete BS! These LS engines are the pinnacle of “bulletproof”. Do they have failures? Ofcourse, all manufacturers engines will, especially when kids squat all of them and WOT everywhere! Not to mention only changing the oil when they remember after the 10th time putting off(because the idiot minder only helps the literate, white collar operator, who’s still paying student loans). GM has always made a decent V8, and almost all engines will last without major problems with proper maintenance. People have put to much faith in technologies and have failed to do the required to keep theses and most vehicles in proper operating condition. Manufactures dont say to service at specific intervals to keep your dipsticks clean! Service regularly people! I digress.
You can’t fix stupid
THE A GENTLEMAN MADE COMMENT ABOUT PERSON SHOULD HAVE CHECKED HIS OIL.Well my Truck Oil pressure dropped plus the Truck had Only 30,000 miles on it and just had an oil change.Must be a GM ENGINEER.I believe if the Company makes a mistake own up to it which alot of Engineers won’t do that.
Had this exact issue in my 2010 GMC Sierra. Led to a misfire that was revealed to be a bent push rod. Did a DOD Hardware and Computer delete, problem solved. The active fuel management system that turns 4 of the 8 cylinders on and off is the culprit.
The hardware delete cost me over $1,500 in parts, but totally worth it in the end, and led me to put a Stage 1 cam in the engine. Truck runs like a champ and no more burning oil issue.
Dodge had same issue around same time with there HEMIS, seen many of them but luckily it wouldnt bend a push rod. Not a fan of cylinder deactivation…
I just unplugged Oil Pressure Sensor Switch and the AFM doesn’t work without that and who needs to read this gauge ,no oil pressure anyway.
I have a maintenance free engine- people that complain about major engine issues.
I can understand why this is an issue. My yukon “misplaces” oil every week. Forget about if I go long distance, the light will come on in a day or two after. After purchasing an expensive vehicle no one should have to replace oil every week.
You can fix stupid, but it will hurt
2004 Silverado 2500 HD. 270000.
I do all wrenching.
Change oil every 2500 miles. Add Lucas.
Just r and r the heads. Shop asks why I am getting them rebuilt.
Drive her nice and easy
Keep her lubed.
Going to take her to 500k.
I love chevy.
I love my caddy too.
You people its thats stupid 8 to 4 cylinder deactivation to save a quart of gas every 20 gallons what b.s. buy a hemi
Definitely NOT BS! This has been going on since GM added AFM to their V8 engines in the mid 2000’s. The LS engines are wonderful engines as long as they don’t have AFM. The rule on AFM is, if you don’t have it, don’t get it. If you have it get rid of it. It can be disabled in about 3 different ways and if it’s disabled before it destroys your piston rings you can prevent the oil consumption, but not the lifter problems associated with it. It requires an engine tear down to completely remove the whole system and it’s associated problems.
I’ve replaced oil pressure sensor ,valve cover gaskets and oil pan gaskets in my 2011 Silverado with the 5.3 with other repairs totaling $3,000 or more to find out gm engineer’s knew of problems so I want in on the class action lawsuit they neglected to inform the consumers
I have a 2006 Chevrolet Silverado, only have 484,391 miles on it. Still runs great uses less than a quart of oil between oil changes. Started using a little oil at 300,000. Guess that not to bad with the miles. Strange thing is that it doesn’t smoke. Usually use Risolen or Marvel Mystery Oil at oil change.
GM has been known for years to use and leak oil. It is just part of their DNA. Stop complaining and stop buying their junk. They begged us to bail them out of financial trouble and then killed over 200 hundred people due to a part that cost less than a dollar. And people still buy this junk. They moved all their production to Mexico and bankrupt Detroit. Great American corporation. Lol, sounds to me like yall got what you paid for. 100% junk.
Irony at its finest as the Hemi engines also have cylinder deactivation in the Ram 5.7 and 6.4 as well as the Charger/Challengers with automatic trans and 5.7 or 6.4 engines.
First of all, Hemis have cylinder deativiation. Second, I have owned several cars with it, and my brother owned many GM pickups with it. His were driven in commercial service, and usually were changed for new at 350,000 to 400,000 miles. The engines in virtually all of them were flawless in every way. No oil consumption, no bent pushrods, no this, no that.
I have no explanation for the “good luck”, but, there it is.
My documentation is on file with the my GM dealer. I visited with them about loss of oil well under the 100 k warranty claim.
Everyone standing up for “correct lack of maintenance” should not own a car. They all have an oil pressure sensor. They all get triggered when roughly 2 qts low. 2 qts low won’t damage anything right away. Over time, sure. But over time you should start to learn that you need to add oil. Lazy ass people. Too good to get a drop of oil on your hands?
EV’s can’t come soon enough for these people, no wait, then it will be lawsuits on no “low spare tire pressure” or “low washer fluid” warning sensors.
The years in question do not Kyle
Oil level sensor. Oil pressure sensor does not detect oil level, just oil pressure.
Bow tie till I die
It’s aboit damn time. My 2012 didn’t burn a drop when I bought it, then all of the sudden it’s down a quart every 3000, I’d be fine with a qaurt in 6000. If the EPA didn’t have everybody by the balls we could just get rid of all the stuff that causes it! That’s who should be sued. Same goes for masks, just stand up for yourself before you have to make modifications to meet requirements, only its not oil you’ll be low on.
Oh boo hoo pal. What that mask hurt your face? Is it to hard to breath? Does it make your poor liittle face break out in zits? I’m free to do all the things I did before as long as I put a mask on. No one’s taken your freedom, youve just politicized common decency. Maybe if people showed even a little bit of willingness to work towards making life safer for people who are vulnerable to aggressive lung infections you wouldnt be getting told what to do.once again boo hoo, I’m sorry it so hard on your soft little soul.
This a major problem. We have two 2015 K9 Tahoe’s that can’t go through a 12 hour shift with out consuming 2qts
And that would be an actual problem. Much more than 1 qt every 500 miles I would assume
I have a 2008 Avalanche with a 5.3, 193,000 miles. Doesn’t fall in that year range and doesn’t burn oil at all.
I bought the active fuel management delete module from Summit and put it in my 2012 GMC Sierra. Problem solved.
The engineers should slow down and make something work, then put it in the line. I love all makes of vehicles, rhey all have problems. Don’t hate the player hate the game. Loves ya all be good
Good Man. I’ve been spouting about the Range Tech. module for months. It fixes 99% of all AFM problems. If GM really wants to improve CAFE numbers, put 3:08 gears back in the rear axle. Just like they did a long time ago. put the 3 speed Turbo 350 or 400 trannys back in. Then leave them alone!!!!!!!!
Buying a Dodge Hemi is not going to solve anything. They use the same exact system that GM does. The only difference is that their lifters seem to be even more failure prone than GM’s.
I have a 2005 silverado 2500 hd crew cab with 8.1 vortec and allison tranny the motor eats 2 qts of oil every 3000 miles and has done this since day one any ideas on cause or fix
GM has been known for years to use and leak oil. It is just part of their DNA. Stop complaining and stop buying their junk. They begged us to bail them out of financial trouble and then killed over 200 hundred people due to a part that cost less than a dollar. And people still buy this junk.

Well within the acceptable limit. Keep oil in it and you won’t have any problem. Check and top off every fuel fill up like is documented in the owner’s manual.👌
Get the Range Tech. AFM delete module. $200.00. It’s worth EVERY penny!
The Hemi engines also suffer from wiped cam lobes on certain engines and we have personally seen this with around 100K miles even on later model 2012-2014’s
2009 Silverado with the 5.3L “AFM” NEEDS to be included. Mine currently has the problem.
No offense but these issues happen to any vehicle when they get on the higher side of mileage. Its completly normal for piston rings to not hold up like they used to after 200k+ miles, it’s called wear and tear. and lack of proper maintenance will just cause the problem to happen sooner, my 05 silverado with the 5.3 v8 LM7 (which is pretty much the same as the LC9 in the tahoa) has the same issue, but, the truck has 250k miles on it, I
just make sure and check my oil level once a week. SO WHATS THE REASON FOR A LAWSUIT, YOUR 200K PLUS MILE VORTEC SUV IS BURNING OIL AFTER SO MANY MILES, BIG WHOOP
What are you talking about the new transmossions are worth a bunch of milage and lees wear on engines. I have no problem with old school but use your head
what about 06 monte carlo ss,it should be included.mine uses oil because of the active fuel management
I have a 2006 Chevrolet Silverado, only have 484,391 miles on it. Still runs great uses less than a quart of oil between oil changes. Started using a little oil at 300,000. Guess that not to bad with the miles. Strange thing is that it doesn’t smoke. Usually use Risolen or Marvel Mystery Oil at oil change.
This is because you take care of it. We’ve had Chevy V8s in the family for years, some going to 350,000 miles before trade, Virtually no oil burning in any of them. No Rislone, no Marvel, no nothing.
I daresay the only time an aidditive has been used in any f our family vehicles was for my 1974 Opel Manta. Those things could clatter like a sewing machine if the lifters got out of sorts. GM’s own oil additive knocked that out within a few miles. The Buick agency told me not to overdo; one can every 20,000 miles or so would solve the problem. They were right.
I had a 2007 Tahoe that I brought from the dealer with low miles back in 2010 that would get so low between oil changes that the lifters would tap!!! I first thought that the people that changed the oil didn’t refill it properly, topped it off and about 2500 miles later lifters tapping again!!! Traded it!!
has any one check 4.3 same block just two cyclider less .there a problem with oil and takes out rod bearing.
My 2014 Silverado w/V6 has the same problem after oil changes & running approx 2000-2500miles its 2 quarts low on oil. The computer notified me oil level low on several occasions & I took it in to the Dealer & they did an oil change & told me to come back after 2500 miles. When I brought it back it was 2 quarts low again & since I bought the extended warranty up to 120K they replaced the pistons & rings etc. $4000… The service adviser admitted to me that he sees alot of V6’s with the exact problem & that I was one of the lucky ones since I purchased the warranty.
I have a 03 blazer and have rebuilt my engine once at 121k from a snapped timing chain taking out the top end, i had the heads ported and bored and polished to put 350 top end parts in(pushrods,spring,rockers,etc) and bigger cam and had the cranked turned 180. Shes sitting at 271k and doesnt burn a drop. The 4.3s suffers alot from the spider injection and being slow turd but they are solid engines

Lol Thank you Kyle ! Guess there’s a reason those little gauges and lights are referred to as “Idiots lights”.
My last 9 vehicles have been Chevy’s. My most recent one is a Malibu. I paid for the auto start, but I can not start it with MyChevy app unless I pay for the useless OnStar. I am not paying $20 or $30 a MONTH to start my car. I never had to before. Had I known they changed, I would not have purchased it. I’ll never buy a Chevy again. It’s Toyota for life.
You are every bit as likely to pay a monthly fee to Toyota.

Wow..So this problem comes to light..So what about the 5.3 that are in the the older trailblazers…I have a 2006 with the 5.3 that has the same problem..I’ve had to replace the motor because of a messed up Rod and the same problem is going on again with the oil situation.It would be nice if the problem could be fixed.
I have a 2001 Silverado Lt with the 5.3…It has 251651 miles on it & drives really good..Has a little lifter slap at startup for about 30 seconds..I use Royal Purple full synthetic oil & change the oil every 4000 miles no matter what…Its got a full K&N filter, Headers, Flowermaster Super 40’s, Accel 8mm wires & crammed..this thing will fry the tires right now…I keep up with the maintenance…I gotta give GM some props that 5.3 of mine is one strong motor.
It started way back in the late 80s. My Dads 89 3/4 ton Chevy burned oil like it was going out of style. Had the engine rebuilt at only 80,000 miles! Those vortec motors are crap.
2007 tahoe ltz 5.3 flex
Has the same problem. How come the year 2007 & Up isn’t included in the years listed that was considered kinks being fixed.
We have a 2008 Chevy Impala SS. It has a 5.3 that is always missing oil. I’m currently in the process of rebuilding the engine. 🙁
I had this exact problem with my 2007 Tahoe just before the warranty was to expire. All the mention fixes they did and resized the piston rings. ( Verbiage might be off). 2007 Tahoe 13 yrs old and still driving good. 280000 miles
I’m 62 yrs. old and I’ve been a Bow Tie hand all my life. I’ve never had an engine failure due to anything. In fact the Bow Tie hasn’t failed on me yet. I’ve had nothing but great performance, relialability, and great luck with them. If course I maintain them myself, changing the oil EA 3K miles, keep belts, hose’s replaced EA 40K (Or sooner) Have radiator rebuilt EA 60K, or sooner, change the coolant EA year etc… Never break down, no problems….NADA! You rap what you sow!
I had a great father he really mentors me. So you see there’s way more in preventing engine failure than meets the eye!!
I have same problem with my 2009 Chevy Silverado ltz I spent over 14000 dollars to fix and finally the treats of the block mess up replace crank shaft lifters new oil pump and Chevrolet dealer no wants to replace the engine after 4 time they open the engine mess up the block I need my money back from GM
If im not mistaken, all of these 2010 and up vortec engines are the Active Fuel Management or Displacement on Demand engine designs that use Cylinder Deactivation for a little extra gas milage. The only way to fix it is to do a AFM delete kit, have it tuned by someone who does these all the time, and have a catch can system hooked up to the intake to catch any extra oil that will sneak through.
04 Yukon XL 5.3 flex 330k had for years has used oil from day one. The amount is always the same about 1.7 quarts between every oil service, so GM has known this was an issue all along and now if forced to deal w the issue (albeit) as cheaply as possible will be the outcome, what about the thousands of suburban/yukon/tahoe/silverado/ cad owners that fit that bill for a new engine 6 months out of warranty? 6.0 ain’t cheap
07 suburban ltz 5.3 flex worse suv i owned. Day 1 problems. Dealer wouldnt take back. Now it has 147k and i still have crappy days . between burning oil . crap pressure. Crap intake. Bow tie is just a swad of toliet tissue.
You must be unlucky. I have a ’07 Suburban with the 5.3 Vortec, 180k miles, runs like new. Burns about 1 – 1 1/2 quarts when it nears 3k miles from the last oil change. I’ve even taken it in with NO oil on the dipstick for an oil change and still haven’t had any issues. After 13 years of driving it, I consider that engine bulletproof!
The 305 and 350 engine that began the early look of the bortec back in 1987 when the pickup debuted with throttle body fuel injection they had their issuses .And right at 190 to 220 HP they were pretty guttless.Cracked heads ,valve stem seats dring up becoming so brittle they would actually fall off..In 1996 we got the first experience with the real vortec . with torque and horsepower gains we still had the same issues .However the new so called small block changed everything.and yes they too have their problems .But have to admit they are a beast. Their head design is so impressive that I personally don’t even want to build a 350 or even a stroker .THE LS and the LT .are some incredable engines .
But the truth is and will always be about maintence and the proper \ correct weight of motor oil .Back then and today if don’t service your engine on time you will have.failure .Oil cunsumption no doubt that is and issue .but like I said.The small block is a beast and one heck of an upgrade
Just my opinion.
Get a full cam kit why not, put a double roller on it cold air tube, some exhaust and a custom tune on the dyno. I paid a little bit, but truck runs great.
This is for the guy crying about the mask issue to hard to breath it’s uncomfortable blah blah blah it’s obvious you have never had a woman sit on your face….
My 05 Denali had this issue the day I bought it 90k. Had to take off the valve cover gasket and move that pcv opening over some. Runs fine for years now. Before I couldn’t go from Michigan to Ohio without adding oil to come back. It still burns but very very little. I’ve been across the country in this thing 3 or 4 times and many smaller trips since, in 5 years now at 203k 6.0 still running good.
How does one define a “design flaw”? Collect data on the reliability of all V8s manufactured since 2000. Build in adjustments to account for arduous duty, climate, buyer profile and price. Take the model that has the highest reliability. Do the rest all have design flaws? If a model has higher oil consumption as the miles rack up, but is more efficient, lighter, quieter or smoother running, is that a design flaw?
Gm has not built a good truck since they left Canada!! It’s the reason Oshawa will be building trucks again!!
My 04 suburban has been doing this for years. Start up big plume of smoke sometimes, hard acceleration, or long trips. Check your oil everytime you put gas in.
I always been “Bowtie till I die” these days im out living what GM is building. I do have one pre 70’s sbc 4bolt that is holding true. Other than that everything else GM putting out now isn’t worth what they ask in purchase price. Everything produced now returns oil back in the intake. Now in regular maintenance schedule is valve cleaning and regular additives. We are becoming more prone to throw away society. Suppose our engines next. Its about quanity not R&D!
PCV is the culprit
My2007 envoy SLT is doing the same thing with only 250.000km complained about to the dealer they kept saying there’s nothing wrong with untill the engine stopped .I feel like gm new about it they just didn’t want to fix the problem
I had this same issue in my 2013 silverado……and the stupidest thing they could have done to these motors was the afm.(active fuel management)……them damn lifters screwed up the cam…..and ended up having to do a full dod delete(displacement on demand), by swapping out the cam, lifters, w/ tune & plenty more. It was worth all the labor. But I do want to mention if your going to do this job yourself , don’t forget to change out the thrust plate. I don’t really have much oil consumption any more and the truck runs great. It’s nice to feel true power of 8 cylinders all the time. Summit racing helped
My brother in law has a 2017 Silverado 5.3L and the top end already went on it with 70000km, the problem is real and doesn’t stop in 2014. 5.3L are junk. Buy a 6.0L or a 6.2L, loads of power and last forever. I am a chevy guy but will never own a 5.3L
My 2007 Chevy Tahoe leaking ever since I got 2010 It I just replace the motor a year ago That’s been leaking since 2010 I just replace the motor that I said For some reason Just the other day I was a quarter down I hope that not a Problem with this new 5.3?
I have a 2000 gmc 1500 with 250,000 miles only problem I have is a lifer tapping but the rear end has been changed so the 4.8 must be the good engine
The pcv systems where designed to ruin vehicles, we didn’t need them before why now. Only way to slow down the oil gunk from the pcv is adding a oil catch can, and now direct injection systems+pcv they are definitely prone to failure. Misfires like a mf and burning oil will be the death of the combustion era. Its probably on purpose so people switch to EV.
A sibbling of mine just bought a new used Silverado and not even 3 weeks later a lifter went bad and thats all she wrote. I’ve seen Toyotas affected by the pcv system as well but they won’t throw a rod anytime soon just got to keep up with the maintenance, some systems are way more delicate and not built Like a Rock!
415,000 on my 97 5.7 vortec before I swapped her out last year. She earned her retirement.great engine.
My 2007 GMC has this issue. It is a DOD engine. (Displacement On Demand) it was eating through oil like crazy. 1 liter for every 1000km.
However, I had it programmed to stay in V8 mode. This drastically improved the oil situation. Many times I can go to a full oil change without adding any.
Engine now has 330,000km. But it is getting much weaker as I would expect.
However, I do have friends that were not so lucky.
IF YOUDon’t buy Chevys the world would be a better place
Im having the same problem with my 2008 Chevy Suburban and now I’m sure there’s engine damage. I havent been driving it for months now.
My 2015 Z71 has had the upper replaced after a lifter went at 70,000 miles. Was covered under warranty but will happen again. Now at 127,00 miles and when this engine goes I will purchase a crate motor. Chevy should of kept the 5.7L
I have a 2011 gmc sierra was having issue with smoke on start up when I changed oil replaced 1 quart with Lucas oil stabilizer and never had smoke again I do this every oil change now still no smoke
I have a 2002 GMC Seirra with the 5.3 l just hit 400 thousand miles and it’s still going. I have to add maybe a quart every 4 to 6 weeks. But it’s been a great motor.
Same problem 2007 motor went out pos
I HAD a 2000 Yukon Denali, great car, except that bulletproof 350 failed at 85000 miles. This car was as new, oil changed every 5000 miles. When I brought this car 8n for service nobody would believe it was a 2000, had it till 2017. A trip from Upstate NY to downstate, about 700 miles round trip, an oil failure occurred and car threw a rod! Was going to cost me too much to put in new engine so sold it for a big loss. Would not buy another Vortec engine again, no matter what car it’s in. Sorry to say my Nissan 300ZX had over 200000 miles on it with not an ounce of problems and didn’t burn any oil at all. GM maybe should get some advice from Nissan and Toyota!
Same problem motor went out 2007 Silverado
I had a beautiful 2000 Yukon DENALI with less than 85000 miles on it when engine failed due to oil failure to engine. Leak was repaired and checked before short trip, about 750 miles, failed again causing engine to throw a rod. I could not believe such a highly acclaimed engine could fail that way. Had to get rid of car. Took big loss.
Yup replaced the engine in my 2008 Silverado do to the same problem they’re talking about. And once I replaced the engine it messed up again and had to have it fix again smh.
Their loophole lies in the owners manual. They want you to check oil with each gas purchase. So why all the expensive bells and whistles to detect and alert. Changes need to be made for sure.
My 2014 chevy tahoe leaks oil also can’t find oil resadu any where its like it burns it i have to add about a 1 quart every 3 weeks or so good read hopefully something good come out of this lawsuit and will get a new engine
I have a 2011 Silverado ABSOLUTELY no issues 121000 miles best truck I’ve ever owned, frivolous lawsuits butheads trying to break a great company!
2008 is about the newest vehicle i want. Ive got a 08 silverado with well over 150k on the odo and haven’t had any engine issues (knock on wood)….. Replaced the motor in my wifes yukon because some of the special lifters that allow the AFM to work callapsed…. (I could have done the work myself without having to replace the engine but thats another story)
I have a 2016 2500 with the 6.0 Vortec and I don’t see any loss of oil
I’ve had 2003 chevy tahoe z71 for about 4 or 5 years best truck I ever had can’t kill that engine easily I drive for work to other states now only thing is the oil consumption does happen but but I usually used a qourt of loucas oil heavy duty with regular oil every oil change usually fine just this year upgraded to the 2007 suburban ltz same exact engine and love it
Do you have to put your name on a list if your truck falls in those years ?
A quart of oil every week, fouled plugs, usually number 1, 5,and 8 every two or three months, I replaced the valve cover (pvc) about 6 months ago. Was going good untill about a week ago. Just had number 1 and 8 plug foul out again. Sucks there like 8 bucks a piece.
I have a 2007 silverado crew cab with 280000 miles. I’ve changed the spark plugs twice, rear main seal, oring on the oil pick up tube, both belts, motor mounts twice and took the throttle body off and cleaned it twice, and maybe she’s on her forth battery and of course change the oil regularly. she runs great and 5.3 is strong….. but I do have to add oil in between oil changes. I would purchase again
To the guy in the 07 tahoe…..it most likely is ur cam gone bad…..ur gonna have to do a cam swap
I own a 2011 suburban and it has 208000 miles on it. Have three teenage boys that have drove it and a wife with a heavy foot. I have always changed oil when it says it’s due on the read out. Use Quaker state dexos oil it runs fine and never have to add oil between oil changes. Only issue I have is cleaning the filter on fuel vent and vapor canister.
Yeah just replaced my motor. 2007 gmc Sierra. 5.3. Active fuel management system is the worst thing ever invented. I could write a book of all the repairs I had to do to this truck. Had it since new. This is the reason I will never buy a GM 1500 again. They are garbage. 2007 to present 4.8,5.3,6.2 engines all still use this garbage setup. And 2007 to 2009 the transmissions are junk!. On my third on of those, and I never towed anything with it. The only truck I would consider buying would be a 2500 the 6.0 doesn’t use the active fuel management system.
Don’t normally comment but figured I would weigh in. Had a 2000 escalade (granted a 5.7) sold running with 540,000kms. Currently have a 2011 Tahoe 220,000 kms with 5.3 and 2008 pick up with 6.0l 200,000kms no engine issues except manifold bolts breaking. I am particular on maintanance. Don’t get me wrong there are issues but i feel good maintanance will keep them going for a while yet.
I have 2010 chevy Silverado same damn problem oil burning up what the the hell ive spent 3000 already still not fixed
2008 silverado 1500 LT WITH THE 5.3L lmg and lost half my oil in 15 minutes 2.5 quarts burned in just 8 miles the lc9 is not the only one with the issue
Had a 2009 Silverado with the 5.3 vortex. Always had a oil using problem but only about a quart between oil changes which I did every 5000 miles. At 100,000 miles a valve lifter rotated because of a cheap plastic part caused $5000 damage. Called GM said they didn’t have a problem with that NO help. Right after that the oil pressure regulator went bad causing lost of oil pressure again they no problemI could go on and on. Bad thing was I loved my truck, bad motor and poor customer service
Last Thursday Thursday my vortec v8 5.3 in my 2014 chevy blew up for the 4th time. Yes in 150k miles that truck that still owed 10k on was gonna need its 4th engine. This time however it caught fire and burned up all my stuff for my job. So now thanks to gm I got no way to do my job, no way to get to my job and money still owed on that pos. Ins is jerking me around but will pay off but between all the engines and 1 transmission the last 2 years I am spent and gonna be hard to buy anything to go earn money. Thanks gm for taking me out
2013 Suburban motor replaced at 110,000. Put a delete let on the motor so it runs off all cylinders.
I’ve got a 2011 GMC Sierra that I bought used at 43K. It has the 4.8 V8. It now has almost 90K , and has never given a problem. I change oil and filter at 5K, I use it to pull my 16 ft trailer used in construction and a 28ft travel trailer. Probably have put 15K pulling the travel trailer. Maintenance and usage are the keys.
2013 GMC Sierra on third engine with less than 100000 miles 1st was under warranty by one month. 2nd lasted until a month before 1 year warranty expired. Third a month after 1 year expired cost me 600 dollars on some insurance program.
I have a2008 LTZ suburban burns2 qts1500 miles .GM failed on this design.my next truck won’t be a Gm product.they won’t stand behind there products SAD!!!??l
There is or was a class action lawsuit over 2010-2013 Chevy 2.4L 4 cylinder engines. Excessive oil consumption. Same issue with the PCV valve.
It took GM, until 2019 to address the issue. There solution was to reimburse the customer for any expense addressing the issue. If you have the documentation. They should have done a recall and replaced the engines.
GM builds crap and will not support the products they build. I’ll neve r buy or recommend anyone to buy a GM product.
I own a 2013 Equinox with this problem. It consumes 1 quart of oil every 500 miles, on average. You better check it regularly, for sometimes it’s two quarts. It has been doing this since I bought it in 2012 . It currently has 103000 miles on it. I need to get rid of it , just haven’t wanted a car payment.
To all you 5.3L engine owners. GM doesn’t give a rats ass about you. They have your money from the purchase of your over priced vehicle.
Good luck.
I also have this issue with my 2008 Chevrolet tahoe, bought my truck with 97.000 miles, now it has 168.000 on it. Its always used over a quart of oil in between oil changes (every 3000 miles). Mine also pings really bad during cold starts. Only good GM is an old GM! I leased a 2016 impala a few years back and it also used oil in between changes as well..
I have a 2008 Tahoe that uses oil that’s the less of the problem the biggest problem is electrical nightmare door locks keep going out window regulators keep going out. All been fixed by a dealer and all say “they just don’t last” but keep paying us, we like your money!
This problem go back to the 2004 Chevy Silverado I ‘m having that problem now
Wow, I have a similar problem. Well traveling in the mountains I have to check the oil every time I buy gas because for some reason my engine will such out or pump out all the oil. I always carry at least 4 quarts of oil with me because all of a sudden oil pressure drops to nothing alarms go off and I have to shut down right away. When checking oil it will be down 4 or more quarts. I have a 2008 GMC Yukon with 200,000 miles on it but this problem was first noticed under 100000 miles but I just attributed to the fact I thought I had not checked the oil, but apparently that is not the case.
Find it interesting, owned a 2002 with 5.3 sold it at 310,000 miles with no oil consumption at all, new owner still driving it 3 years later. Currently have 2006 with 5.3 with 210,000 miles again no oil consumption. Of course do my own oil changes and maintenance, maybe some should look at who’s doing oil changes or brand of oil. BTW I only use conventional/synthetic blends.
If you really want problems buy a vehicle with a foreign nameplate. Keep your checkbook handy, you’ll need it.
I used to be a huge gm guy. I had a 2004 silverado with the 4.8 and a 2005 tahoe with the 5.3. Both comsumed a quart of oil every 500 miles and both made a valve or cam tick at idle. Ive gotten rid of both vehicles and will never buy another gm again.
I had a 2009 that did that coming from fishing was running find almost back home lost all oil compression
The pcv valve is located atop the valve cover. Normally the other valve cover has this hole capped. Replace that cap with a breather (small air filter) from your local parts store. That reduces the crankcase pressure & will reduce how much air/oil that is drawn through the pcv valve.
Every manufacturer has their issues, they are all crap, most can be attributed to today’s emissions standards it’s not the manufacturers fault that society is based on a bunch of tree hugging hippies, that will not ever see the result of the emissions standards nor will their children’s children, manufacturers are trying but the rules get more stringent. Oil viscocities are decreasing while internal tolerances are decreasing.
I had a 2008 avalanche that I bought new and had this problem from new. Went through the dance with GM and they never did repair the problem for years. Traded it in for a 2013 avalanche and no high oil use.
I drive a 2006 Sierra 1500, 240,000+ miles. Water pump and 2 batteries, otherwise just regular maint. Runs great with no oil consumption issues. It even still looks good. I love this truck.
We have a 2013 chevy avalanche and it uses about 1 qt every 500 miles or so it doesn’t smoke it runs perfect just changed plugs 7 looked great the 8th one the insulator was broken half off it idled like crap and set codes changed all 8 and now it runs perfect but still burns oil. That is how I know the plugs aren’t oil soaked but it is a little worrisome to be honest as it just eats oil like crazy
I had an 07 avalanche that use a ton oil and cooked it had 50,000 on it dealer said it’s fine lol
Had the displacement on demand turned off!
This cured the problem stayed in v8 mode same mpg oil looked good for duration of oil change and used only 1/2 qt in between changes
No matter how hard you try overcoming a poor original design is polishing a turd. The original 5.3 had the valve slap which GM ignored followed by oil problem. Time for a totally new engine design. I had a 2001 5.3 and would not buy any vehicle with to again
I purchased a used 2013 suburban. It was serviced and before 3000 miles went by the oil level dropped starving the DOD lifter bending a push rod and scaring the cam. Almost 6000.00 dollars later and the full delete package NO decrease in fuel consumption. We still have to add 1-2 qts. before an oil change. I hope to get my money back, Lol.
Got a 2007 avalanche 5.3 sitting in yard it started smoking very badly don’t know what to do.
08 LTZ suburban .I bought range plug into obd2 port.it tells the engine to run on 8cylinder all the time..it did help on oil consumption.about 1qt every 2000 mi
now.i have also replace oil sending unit an screen!no more gm for me
On my C8 it says to check the oil with every fuel fill up for the first 500 miles. I would think that having an oil reservoir a simple float sensor would do the trick. Perhaps having a scavenger pump creates too much turmoil as I really don’t know much about these new systems
I have a 2008 Chevy Suburban with a 6.0 engine. It had the active fuel management system in it which causes known issues. Motor blew at 100k miles costing thousands to fix. Had to rebuild rather than replace and bypass the AFM system so I don’t have the same exact issue occur. Ridiculous
I just traded my 2011 GMC Acadia as it was in need of multiple repairs. One of the issues was that it was burning through oil like crazy, yet they couldn’t find any leak. My last oil change they said it was dry. After doing a complete flush, changing oil, filters it was dry again when I took it in for another mechanical issue.
I have two chevy that are burning oil and causing engine issues. Also oil pressure issues
Sames as me chevy tahoe ltz2009… plus sensors ,plus among other things
I own a 2011 Silverado with 184000 miles on it. No problem with engine. The Silverado I owned before this one I traded it in with 260000 miles on it. I am trading the 11 in on a new Silverado trail boss. Would not own anything else.
My 2011 doesn’t use oil I don’t use syntheic oil either went to 10w30 when it was new no problems whatsoever runs quiet no tappet noise and good oil pressure I go 3000 miles on oil changes a lot of these oil burning problems are from poor mainteince and using poor lubricants
I have a 2010 Tahoe 5.3L eats 2 quarts of oil every 3000 ish miles give or take 100 or so miles. I change the oil every 3000 ish miles and the oil life meter says I still have anywhere from 50 to 75 percent oil life remaining. Yes it eats oil. Wish they would do something about the AFM cylinder 7 always gets a misfire and always has oil on the plug.also the Cracks in the dash.
Harrison, Get a Range Technology Plug In. In plugs into OBD plug. Cost about $200.00. on line. Get one. It solves almost everything. Our 5.3, 2012 Tahoe, now runs on all 8 cylinders, all the time. No more extra oil consumption. It’s better than the Chevy Dealer, telling you it’s your fault. Best $200.00 I ever spent.
I have a 2014 Chevy Silverado 5.3 and it has burned 2 quarts of oil between oil changes since it was brand new. It has 94,000 miles now and starting to rust on the rocker panels and cab corners.
How do I get into this lawsuit because mine’s is doing the same thing
My 2014 sierra 5.3L V8 is doing the same thing…low oil light every few thousand km.very frustrated with this
I bought a used 2011 Sierra in 2016. Has the 5.3 and HD towing package. I’ve towed cross country with it usually running 75 mph and run either 5th or 6th gear depending on the conditions (grade/elevation/wind.) It has the cylinder deactivation and I can tell when it’s running on 4 cyl just because of the exhaust note. It has a Flowmaster catback system that was installed by the previous owner so it has some sound but isn’t loud. I have my local GM dealer service it every 3k miles with Dexos full synthetic. It has never used any oil. Oil level doesn’t even go down on the dipstick between oil changes. So I don’t get it-why is my truck completely trouble free and others have so many problems?
My 2014 Chevy Silverado is doing the same thing burning oil and losing power and the transmission shift downward for no reason. And I only got 90,000 miles on it.
ATTENTION: We can comment all we want its not like this will benefit any of the consumers ! !
I have a 2010 GMC Sierra. I have experienced all of the issues listed in the lawsuit. I had to have the bottom end rebuilt with new pistons,rings, and bearings. The valve cover has been updated and regular routine maintenance as well. I have had the afm system disabled for the last 55,000 miles or so. Although I do not have the issue of dropping to 4 cylinders anymore I do have an oil consumption problem. Roughly 1.5-2 qts. Per 3,000 miles. And the oil pressure is and has always been lower than I am use too. But GM continues to tell me that my engine only needs 7psi for every 1,000 rpm. That seems way to low for any engine. My engine also will foul out spark plugs every 30,000-40,000 miles.
While my 2008 Silverado with the 5.3 seems to be out of the date range for this article, I bought it used with 141k on it and it burned oil and smoked at start up for about a year before I did some research and replaced the right (egr) side valve cover with a redesigned cover. Since then it stopped smoking and burns about a quart every 5k which is when I change the oil. I have always used synthetic but I do not know about the prior owner. It’s at 210k now and still runs great although I’m hearing some piston slap, another common issue in these engines. I’ve always used 5-30 but I’m switching to 10-30 and probably should have done that way earlier.
How do I become a part of this lawsuit. I have a 2010 Silverado.
I had a 2011 chevy suburban I trade in because I was having issues with it miss firing and when I pulled spark plugs only # 7 was soaked in oil causing the miss fire I spent alot of money trying to fix it end up trading it in for a 2021 tahoe now the tahoe had issues I wish gm would make a good product for once
I’m having the same issues with my 2011 Suburban LT how do I file to be part of this lawsuit ? 115k
Not only is it the full size SUVs it is the smaller SUVs also with vortecs from 1998 to 2014 cause my s-10 blazer with the 4.3 liter v6 does the same thing and has done the same thing causing the whole engine and ecm to shut it self down where I had to bypass the security passlock the vortec is the worst intake setup ever created by Chevrolet they should be replacing any vortec vehicles midsize and full with brand new ones
I have a gmc sierra 2014 model with the new body style equipped with the 5.3 and ot burns a quart to a quart and a half of oil every month to two months. Which is absolutely crazy. I am very meticulous about my truck. I have 148k miles and it still looks brand new inside and out including the engine bay. Ive never had a check engine light come one, but I’ve had the needs oil light come on religiously. I think gm should have to replace the engines in vehicles that do this. I would love to be part of the class action suit. Gmc is supposed to be one of the best trucks on the market, yet it has always burned oil like this.
I am having the same issue on my 2016 Chevy Silverado 68k miles on my vehicle . Oil consumption about 2 qts last time with a pinging noise and pulling sensation and feeling of turning off and my stabilatrac turning on . Have had the vehicle at shop for over 2 month asking GM to cover the cost of repair or a buyback. And nothing yet I had told them about issues since it had 25K miles . It has a bad valve lifter on cyl #4 , vehicle been serviced at Chevy Dealer all this time.
Need help.
Exact same issue with my 2013 Avalanche. I reached out to GM and the Chevy Dealership. I did receive a call back, unfortunately, I was told that the warranty expired. My truck was only at 80K miles. I shelled out nearly $9,000.00 for a remanufactured engine. Please help all of us receive justice.
2004 yukon xl v8 is that an issue
Why are you still buying GM vehicles!!!
Watch Scotty kilmer on YouTube
My 2007 gmc yukon lifter broke with only 138 thousand miles . Problems with the afm system bougth a new engine from fraiser engines it cost me $ 3200 t installation it was around $5000 dl it only run 30 thousand miles and same thing happen a lifter broke again on a new engine truck is at the shop has i write this comment truck is currently has 168 km i cant belive a truck with this many miles had so many issues olso replace the transmission in 2016 . Overall gmc is making really bad expensive vehicles and leaving the owners stranded with really expensive repairs. Wich something is done to help us out .
JC – 2011 Silverado, my truck has 350000 miles on it and I have always been religious about servicing it, and always at my local Chevrolet Dealer with the same Dexos oil that came in it, which explains the reason it has lasted and still runs great. But yes it does and always has used 1.5 to 2 quarts of oil between oil changes! I have dealt with fouled out plugs on many occasions, about every 7k to 10k miles, but once the dealership replaced the Valve Cover it has only happened once and it was around 18k miles. I really wish we could an answer of why!!! My wife’s 2011 Chevy Malibu with a 2.4 has always used oil. Most occasions even more than my truck! So it’s not only the 5.3!
I have a 2017 sierra with 62k on it. Always had it serviced at dealer. Started using oil around 30k. Used around 2 quarts every 3k. GM just replaced the engine three weeks ago. Hope this new engine is better.
I have a 2004 yukon denali that have had the same problem for years. I have used full synthetic oil for the past 5 years. It has always burn oil. It has the vortec motor in it. Have spent a lot of money on this truck in parts trying to keep it together.
Hi in interested in knowing how did you get the new engine and who did you talk to. Or did you have an extended warranty ? Please let us know . Thanks
I am trying to get my truck buyback . Don’t know who to talk to to escalate this more .
Lifter collapse @ 158,000 mi. 5.3 Vortex. 2007 Silverado LTZ. Opted for re-manufactured Fraser Engine. Out of the shop three days, transmission decided to stop shifting. Now I have young truck in an old truck’s body! I thought it was just me and bad Ju-Ju!
What’s a “Vortex”?
My 04 GMC Yukon XL has 187,000 thousand miles and it run good I’ve been all over Michigan not a problem
Here’s a suggestion, if you have a 5.3 with 150K or more on it, check the oil. Don’t hire a lawyer, when you get gas check the oil, there’s this dipstick thing, you could google it. We have a 12 Burb with 190k, runs great, uses a little oil.
Well I can tell you people that this is definitely a concern with the newer built 5.3 VTEC motor you will have bad issues with this motor if you neglect oil changes and I’m sure that most of these people have this new tech motor has cut down cylinders at high speeds not good for valve Tran or it’s not good for the cylinders Unfortunately they did it for fuel economy but they really hurt the original 53 Vortec which is an extremely reliable engine I’ve got a Chevy Silverado will a 5.3 Vortec in it got a hundred seventy thousand miles on it I’ve never done anything to this engine but change the spark plugs and wires I’ve never even put a waterpump on this motor yet keep in mind people failure to water pumps and brake systems and power steering systems is all in the collect of fluid change it’s important for you to change your motor oil but all those other fluids I mentioned as well as the transmission fluid needs to be changed at certain times two don’t wait until you have a problem with something to get it changed that’s why most people have problems they don’t want to spend the money to take care of their investment if you want your vehicle to last and I really don’t care what you drive if you don’t take care of it properly then you’re going to have issues people
I quit buying GM after my 03 Caddy Deville (NORTHSTAR) Turned to garbage ….MAJOR OVERHEATING…
NEEDS HEADBOLT KIT REPAIR …I LUCKILY found someone to fix it…NOT CHEAP THOUGH 2 TO 3000$ and up Being the car is perfect I chose to do it.
My 93 DODGE DAKOTA has NEVER been in the shop ….MOPAR FOREVER
Lifter collapse is common in these AFM engines. Yourou can get a delete kit and basically rebuild your engine for about 1300$. I’m in the process of doing that right now on my late 07 sierra . That cost includes having it reprogrammed and tuned. We are doing the engine work our selves.
I have a 1996 tahoe doing everything y’all are about oil pressure mine has shut down twice completely costing me 800 dollars both times and still the same
I have a 09 Silverado with the same problem even had to redo lifters because lifters would stick
It’s funny I work for an large truck dealer and i am a master technician. I have owned a 2007, 2010, and now a 2018 silverado and have had none of these issues. I work about 300 miles from home so my vehicle gets 600 to 700 miles a week on it. The 2010 had almost 200 thousand on it when I traded it in on the 18 and had one failure, an alternator. All the ls style engines have the same pcv and it is the same on the older v8 which yup allowed a small amount of oil mist to pass to the engine with no or minimal effect on durability. As for this leaking oil relief valve. It is a pressure relief valve that only opens when an engine see too much oil pressure so maybe on cold mornings but not constantly. Even if it did squirt the piston skirt constantly the oil ring on the piston will remove the excess oil before it reaches the combustion chamber. The ls9 in the zr1 corvette and the lsa in the ctsv and zl1 camaro even has an oil nozzle on each cylinder that does exactly that and no excessive oil consumption. Now if you don’t change your oil and the oil rings wear excessively then yup oil gets in the combustion chamber. Which is what I have seen happen to these vehicles. If your vehicle is burning enough oil to cause the oil level to drop to dangerous levels in between oil changes it would be smoking like crazy. Like fogging you out at every stop light with blue stinking smoke. In the end take care of you vehicle and you won’t have a problem or don’t and I will rebuild it and be able to afford a faster race car again next year hello. Common sense isn’t all that common anymore as my grandfather used to say.
Oil changes help….. ALOT…. Not in the year range they’re talking about but I had a 05 Yukon XL 5.3 and it had 220k miles on it when sold and never once had any major work done and it ran like it was fresh off the lot. My truck I use for work is a 02 Silverado Z71 5.3 engine has 181k miles on it and other than rebuilding the 4l60e transmission thanks to the junky sunshell I’ve never had a major issue that put the truck out of commission. Things happen and parts can and do go bad but lots of things can be prevented with regular maintenance.
Don’t jump in & start the motor & leave My 01 yukon knocks when you start it up then smoothes out after 30 seconds runs like a sewing machine. W15,000 miles.
A Catch can, simple solution
Why are people who dont have a 2010-2014 v8 5.3L commenting on this issue? Its like saying “this gun keeps jamming” and someone relpying with “i use a spin cast rod for pike fishing” irrelevant!!
The 5.3 has always been a great engine in my experience. I have an 04 with 358,000 still going strong. Ticks a little bit when first started but usually quiets down after it get warmed up. Chevy vehicles always.
Ive owned several chevy’s with the 5.3 , and that is a fantastic motor..
But , every single one I’ve owned burned oil anywhere between a quart & a quart & a half between oil changes..
Talking to other chevy owners , I learned they had similar oil loss issues.
I personally think the yrs in question do not encompass the all the yr models with similar oil loss problems…
I currently own a new chevy truck.
But my 2004 & 2005 Yukon & Suburban have the same problem..
Especially when towing .
My 2004 yukon burns a quart every 1000 miles & has done since I bought it.
I’ll continue to by chevy, simply because the durability is unmatched in the industry…
I travel around 50k miles a yr & usually donate them at 400k.
One of the best engines made in an american vehicle ever. Lol. People will find anything to try and sue over. People pumping 1000 hp out of the same stock engines but others want to sue over having to add a court of oil every 3000 miles.
I have a 2010 GMC Acadia with the 3.8 Vortex motor that is doing the same thing I think it’s the motor brand its self it’s poor construction putting in a full size vehicle over whelmed the engine .
I think some of the posters on here claiming oil problem issues are looking for a payday
I have two four wheel drive Chevy trucks with this engine. I have treated both like a readheaded step child, i.e. burn outs, hold it to the floor until it hit the top speed limiter. No problems like what has been described. CHANGE THE OUL LIKE THE MANUAL SAYS. DO NOT WAIT FOR THE PROBLEM SHOW UP AND THINK CHANGING YOUR IIL WILL CURE THE ISSUE.
My 2006 impala ss that had a 5.3 and my 2007 gmc sierra which also has a 5.3 have both had the oil consumption issue. A friend whom had a 2008 grand prix gxp also with the 5.3 had the same oil consumption issue. So it’s not just the 2010 and newer 5.3s.
My 2009 suburban has the same issue im using anywhere from 1 to 2 quarts at a oil change
I got a Jeep Cherokee with a 4.0 liter motor, over 504,00 miles. No oil problems. Nuff said
I have 2007 suburban with the 5.3 vortex. Since I purchased it I was going through two-two and a half quarts of oil between oil changes of every 3000 miles. Chevy did an oil consumption test on it. GM confirmed the oil consumption. The manager of the dealership gave me a bulletin from Chevy stating that it was normal for those engines to burn that amount of oil. When I hit 100k miles, the engine blew. Chevy stated that since it wasn’t under warranty anymore they couldn’t do anything.
I have the 2007 silverado vortex 5.3 , and I have the same oil consumtion problem as well.
I think it’s BS at stopping at 2010 I have a 08 and just had to replace the engine after 218,000 miles. It was burning plug #7 out every 15,000 miles. I took my truck to the dealership every 3,500 to 4,000 miles and had my oil change. I use Mobile One Synthetic
I have Chevrolet Silverado 2008 5.3 L
Every 8000km I add oil between 3 to 5 L and I made a complaint to the Chevy dealer did some test I did end a say normal (Really) with a nice smile
My GMC use a lot of oil i have to keep oil in i keep the oil change i have a 2001 series
Simple solution buy Toyota.Had an 03 with 409 klms never any issues,never added oil to that 4.7 between changes.Now drive another Tundra with the 5.7,again no issues,these trucks are bullet proof.Wake up gm people!
I have an 03 Silverado with the 5.3. I’m a retired ASE certified mechanic. At 152k miles had to replace the engine. Issues were: both heads cracked (Castech castings), collapsed lifters, 5 psi oil pressure at highway speed, severe knock. Pulled pan and clean as a whistle. Always changed oil using correct weight synthetic oil and quality oil filter. Made no difference. I’ve been a Chevy man my entire life, but no more. There’s a problem here folks. On top of that had to replace brake lines due to two instances of lines bursting due to corrosion. Thank God I didn’t kill someone’s child because of it! I live on the Eastern Shore of Maryland, not in the rust belt. Most years we don’t even get snow so this was not a salt issue. Non-wear brake components should never fail. IMHO just overall excessive cost-cutting by GM. Probably the greatest car manufacturer the world has ever seen reduced to this state of affairs. Very sad.
My 1954 S-10 had the same problem. The hemi burned 2 qts in-between changes.
😂😂😂
2016 silverado 5.3 liter with Active fuel management
A GM dealer service technician asked me how your oil consumption? Not good I said
Then he told me to buy an AFM bypass module and wow. Not low on oil any more. And have control of V8 mode no gas pedal delay either as it dose not have to switch out of v4 mode.
I’ve got a 2008 chevy Tahoe ppv. I check it daily. Haven’t noticed any oil consumption aside from the minor (which I’m aware of leaks) when plugs were changed they were all severely compromised. Still have a little miss afterplugs and wires. Considering a new ecu and having it tuned.
I have a 06 silverado 5.3 with 325k miles. And its need minimal repairs which i did myself and im not a auto mechanic.
My 2007 Yukon 5.3l with AFM have same issue. Every 1200 miles I have to top off quart.
I have a 2001 gmc serria doing the same thing
I have a 2001 gmc serria doing the same thing. Since i brought it seems its falling apart
I own 2000 z71 Tahoe 5.7 just put in a newly crated engine complete. Love this truck and the 90’s body style. Anyway I was thinking of buying a 2021 silverado trail boss which has the 5.3 , should I change my mind a get a dodge laramie instead. ???
I also own 2017 Ram with 5.7 hemi and it’s got plenty power. I have 35000 miles on it now and no oil issues. My average mpg is 17.
Only issue I had was my fuel sending unit went out at 34000 miles and warranty won’t cover it and it is known issue. I replaced the whole fuel pump myself.
Ford with 5.0 have best realiablity reviews but they’re expensive.
Still love the truck.
Ironic – I have a 2010 1500 crew cab Z71 4×4 with the 5.3z. I’m JUST having this problem at 178,000 miles. I replaced the oil sending unit and filter (twice) and the rear main seal back in March. The other day I got a Low Oil warning with the Red oil symbol. Display said Turn off engine. I pulled over. Checked oil. It was low. Got oil change yesterday. So now that it’s full it’s off. I do mostly HWY driving. I’m on the fence with this one. Anything mechanical will eventually need to be replaced, or at least maintenance. I do all the PM at the dealership or at Christian Brothers. I’m trading it in in about a week for a Tacoma. Gonna miss my truck. Got it with 7 miles. Been great but figure it’s time to part ways.
I have a 2001 serria Gmc i did a oil change 2 days later my oil light back on i have the 5.3 in it i feel i have to change the oil every 3 days in it
my 2001 serria Gmc i did a oil change 2 days later the oil light goes back on i have the 5.3 in it i feel i have to change the oil every 3 days in it
My 2001 gmc sierra i change the oil 2 daya later the lights back on seems i have to get a oil change twice a week its insane how much money i spend
Have 04 Sierra w/5.3. At 90K, had to replace heads due to porosity affecting 02 thru 06 5.3 and 4.8 engines, GM knew about, did nothing, no compensation, out of warranty. They do nothing for customer loyalty like Toyota does!
I have a 2004 Chevy Tahoe and its doing the same thing
GM, Gov’t Motors! Remember the Bailout!
I’ve got a 2018 with engine issues where the heads are knocking and I’ve been told it’s “NORMAL” operation. Same 5.3 liter engine and GM refuses to buy back. I have always been a Chevrolet supporter when buying cars, but after the way I was treated, NO MORE. Ill take my business and loyalty somewhere else.
If you disable the AFM, such as using the Range module. It stops oil consumption.
My 2009 Avalanche had that exact same issue and now I have a bad can shaft and lifters.
I have a 2011 silverado 1500.. I had to have the pistons and rings replaced 4 times before it hit 80,000 miles… 1st time it happened it was around 30,000… then 3 more times….luckily I bought the extended warranty.. i complained to GM for months. There final solution was to warranty it till 160,000 miles.. then I’m on my own, or they suggested I trade it in for a new truck and a another 6 yr pymt plan… I told them after 4 times. They owe me a NEW engine.. any other appliance store would’ve replaced the affected item.. we deserve to be compensated for this. There is a reason they stopped using that engine after just a few yrs of it being designed.. because its garbage.. so much for like a rock..
I’ve got a 2007 chevy avalanche it burns 2 qts.of oil every 300 miles. Dealer performed service bulletins (I paid out of pocket)and eventually told me it was normal for an engine with that many miles to consume that much oil. I’ve had to replace the catalytic converters twice just so I can get state inspection.
Lmg smokes on cold start or after an HR or two of driving and let it sit for 10 15 mins? Valve guides/seals are common after 120k the valve cover on the drivers side if not updated (gm added a baffle) to help block oil from rockers being picked up by pcv the passenger if equipped w forward vent and usually are can slurp oil into plenumn and into engine killing cats and 02s.
I had a 94 Chevy 3600 and had nothing but good luck almost 500 k after 2010 Chevy just went to s…
I have an 06 tahoe 5.3 L with 165,000 on it. Using mobile 1 5-30 full synthetic oil and changing it every 7 to 8,000 miles I am usually 1/2 qt. Low on oil when I change it.
Same/similar issue with my 2014 Tahoe but fortunately it was under warranty still so dealer had to pay to replace whole Engine
I have a 2001 Silverado 1500 HD crewcab 4×4 with a 6.0L vortec. I checked all fluids regularly and changed the oil when the information center flashed “change engine oil “. Even though I took care of my truck the engine blew up without warning. I can only wish I had the money to replace the engine.
Local self pull it yard is a good place to look 6.0 you’ll find in Denali Yukon and Cadillac Escalade / Denali a used long block if you yard it yourself starting at 150-300. I would recommend going through it while out of truck. Make it fresh and new to your specs.
Yup I too have issues with my Chevy. 2011 Tahoe and it eats 2 to 3 quarts of oil between oil changes. My wife is scared of any lights or messages, so it gets oil changes regularly. Yes my rear main seal leaks too, but not 2 to 3 quarts worth. While we are at it why in the heck did they design the oil pan to wrap around the filter. As a Ford guy, driving Foxbody Mustangs since 2000 Chevy sure does like to make things difficult.
The wrap around pan is for oil cooler return if equipped there are two ports that one from pump to filter and cooler output and return.
Yup same issue here!!! 2009 silverado crew 1500 4×4 , 109k miles and uses 2 qts between oil changes!!! Wtf GM!!!! Stop dicking us consumers around!!!! I’m a die-hard Chevy Guy! Get this fixed ASAP!
I am a Chevy man but there newer trucks are the ugliest trucks out of the big 3.People should stop buying them because of engine issues that will not stand behind .They are making record profits off the junk they are selling .
There’s this thing called a dipstick, pretty useful. My ’02 6.0 vortec loses a quart every 4k on synthetic. Boo hoo. Make a run to the oil aisle, it’s not expensive or difficult.
I have a 2008 chevy tahoe ltz with the 5.3 vortex flex fuel with 255,000 miles. I had that issue that when I went 3,000 the oil was 2 quarts low . I read up on the issue to find out that the drivers side valve cover was the problem. The vent for the pvc valve was designed where the vent would suck the oil up from the rocker arm and would burn the oil from the intake manifold. I went down to Summit racing and they had the updated version in stock . I never had a lost of oil again .
If you think that’s bad, wait till the problems start happening with the new 4 cylinder turbo on the new trucks. What the hell was GM thinking putting 4 bangers on a 1/2 ton truck. I seriously doubt you get 75-80k miles out of that engine. Sucks! I’ve always been a GM man…
They need to add the V8 Colorado and H3 to the list! These also had the 5.3 with same issue. I kept complaining about morning start nock but they said everything was fine. I told them of the oil loss, they couldn’t find a leak. I traded it off for a V6 Colorado! I miss the torque of a V8 but not the fear of failure.
They need to add the 4 cylinder engines found in the malibu’s also
I have a 2009 GMC Sierra that is giving me the same problems. I did all the fixes on the vehicle bulletin but it still burns around 2qts of oil between oil changes. Doesn’t help that GMC dealerships and mechanics play dumb or are dumb! I am the original owner but I don’t plan on buying another GM truck in my future.
Do the 6.2 ltr have this problem or just the 4.8 and 5.3 ltr I have a 2013 GMC Sierra with a 6.2 and a 2013 Chevy Silverado 4.8 thanks in advance..
Hi in october 2016 I bought the chevy suburban lt to do uber and less than 2 month I had a bad experience something happened with some hose causing all the oil to spray all over under the hood I had to call a tow truck to take it home because it was after midnight then take it to the dealer in the morning they repair it ok good then couple weeks later I had like misfire and couple time it wud pop up showing low oil then I stop doing oil change at the dealer that problem solve this vehicle was a brand new vehicle and within the first 6 months I been getting lots of problems and the dealer which is bical Chevrolet on valley stream are a bunch of crooks espicially the manager who charge me couple thousand extra when I got the invoice which was couple days after I bought the vehicle then I suppose to get the vehicle with the captain seats I didnt get that but was told I wud get a check of $1200 back as refund the manager had me like a fool going there for months asking for the check which I never got till this date I just got tired and didnt bother to ask again they are the worst set of sales people and manager at bical chevrolet valley stream I wud never go there or send anyone there to purchase a vehicle they show you the nice side until they sell you that vehicle they dont care about you after ah bunch of thieves.
Don’t give up, tell local paper and ctv news make a huge stink and get your money back buds! Don’t let the crooks win they won’t stop ripping others off too.
Engines also use oil when they are driven on many short commutes. They don’t have time to heat up and get that thermal expansion to take up tolerances. This means most of the miles are driven on a cold engine wich burns oil. I dont know if this is the issue of the effected people but it was happening in my 04 4 runner V6.
Have an 07 Trailblazer, short wheelbase, 2 wheel drive, with a 5.3. I bought it new, put in 3:73 gears and had the computer tweaked. I broke it in and then ran Mobil 1. Much lighter than the pickups- this thing SCREAMS! Does not use oil. Very careful to drive easy when cold due to aluminum block and heads.
I have a 1999 4×4 gmc 5.3 that’s doing the same thing. And as time goes by values rattle more when first starting the truck.
I had a brand new 2013 sierra with the 5.3 brand new off the lot . Within the first 10k my oil light came on and I checked oil and didn’t even register on dipstick! Went to dealer and they topped it up and said of its normal for this engine to sporadically burn oil and just dissappear sometimes and to keep an eye on it! Normal I said? ?? My 30 year old truck never burned a liter of oil in a year and this went thru 3-4 liters in one oil change? Ya they knew of problem back in 2013 just swept it under rug just like the faulty radiators in same year! Bulletin was sent to dealers but they refused to repair under warranty which my engine had also. I fought that one and won and got it covered thankfully. Did they not fully test these engines before production ? Now my 2017 silverado is having issues with engine and tranny shifting I’m not going to be buying GM/Chevy again I think anymore I’m so dissapointed and frustrated.
My 2008 Silverado does the exact same thing I have to put at least 2 quarts in my engine and with the cost of oil these days it’s just as expensive refill the oil as it is to do a oil change
2008 GMC Sierra 1500 5.3 vortec, best engine I have ever had, 187,000 and does not burn a single drop of oil. I have used synthetic consistently. Also have a 2001 conversion van with the 5.7 vortec v8, still running strong after 165,000 miles.
This plaintiff has a huge stair to climb.
These guys need to learn the difference between warming up a cast iron vs an aluminum block. You better go Very easy on aluminum when cold cause of the total difference in the expansion rates of the metals. I drive under 20 first thing for about 4 or 5 blocks and no hard throttle till COMPLETELY warmed up.
I bought a 2020 Chevrolet trailboss in February and it ran itself low on oil. I eventually had to have the motor replaced. It’s been running good since the replacement in October.

Not a truck…..but i have the exact same issue with my 07 Grand Prix GXP. Have to add 2- 3 quarts every 4-5 weeks.
A couple issues here. 1. People expect the engine to make it between oil change intervals without having to add oil. That’s absurd. Then it runs low on oil and its GMs fault. Once it runs low on oil, you have created your own oil burner.
2. Yes, there are valve cover issues.
3. I check my oil almost every time I get gas. It amazes me that I NEVER see anyone else checking their oil.
4. My 2005 Tahoe will go from Ohio to Florida and back and burn 1/2 quart of oil. That is incredibly good to me. It has 160k miles on it.
5. When you think of the millions of LS engines GM has built, yes, there are going to be some bad ones. It sucks if you got one. It sucks even more if your dealership wont help you. But overall, outside of DOD issues, it is one of the most popular, reliable, durable engines on the market.
I have a 2008 Tahoe that had this problem and had to replace the valve cover at several hundred dollars to fix the issue not to mention the numerous quarts of oil I had to buy. It went from using a quart a week to using half a quart between oil changes. So it’s not a 2010 and up it is for sure should include the 2008 model also
Long live the good old 350. MY ’99 just passed CA smog with 208k on it. It leaks a smidgen of oil, maybe a quart per six months. LS engines are supposed to be the best. What’s going on?
End
I have a problem with burning oil smell inside the cabin on my 2013 Yukon Denali. It’s a 6.2 liter engine and my mechanic and I cannot find the leak. Bone dry underneath, no visible oil consumption, but strong smell of burning synthetic oil. What’s going on?
This problem began with the 2007 model year vehicles. My Brother in law has a 2008 Suburban, that is burning so much oil, I can smell it here in Texas, and he lives in Vancouver.
I have a 2007 5.3 avalanche and she said that the day after she had purchase the vehicle the check engine light came on, trying to resolve the problem with the dealer they told her to take it to a GM dealer but no one has that kind of time an gosh the dealer price is just not possible. So every 2 years smog test only wont pass. The oil consumption is about 1qt of oil a month after oil change. Now after over 300,000 miles on the same engine with a check engine light GM should do a recall on the engine and swap for a different one just to give GM customers a better chance to smog and not paying extra to pass a failed test. I love everything about the avalanche and love a reliable vehicle and that many miles on the engine im looking but no luck on cost for a new engine, please help a GM consumer out
Every buddy I know with these 5.3 from 2007 tell now has had these same problems more than once
Hey bro is 15k miles considered high millage?
Back in 2006 my wife decided she wanted a Chevy trailblazer that she had to have. I went out and bought my first and last Chevy ever after the 1yr of maintenance contract with Chevy it was my turn to take it to a dealer or do it my self. So I did it and noticed it was short almost 2 qrts of oil I took it in on the next oil change and asked to talk to a service tech. I asked the tech about the oil consumption and I was told it was a normal think for it to do. The trailblazer has a normal 5.3 not an afm. It currently sits in front of my house with 55000 miles. Its use is limited to local travel (costco runs) due to the fact that I won’t risk my family getting stranded. I have all Ford products in my driveway and the oldest of my car that’s fuel injected is a 91 bronco and it has 95k miles and it never has burned oil. I’ve owned new Ford’s and I’ve had issues but never an oil issue. Chevy needs to step up and play the price just as ford did with the 6.0 superduty
My 2007 GMC yukon had this issue and my engine went this year.. the fact GM only went back 10 yrs is ridiculous.
I have a 2008 Avalanche with 103 thousand , it uses a quart of oil about every two thousand miles. The lifters also make noise on start up
I have a 2008 H3 Hummer Alpha with the V8 engine. What about those SUV,s
What about the H 3 Hummers Alpha. They are v8,s
Our 2008 Suburban had this same problem. Had to replace the engine.
I have a 2013 Silverado that is doing exactly this. I check the oil every week now since it sucked down almost all the oil in a matter of 2 weeks time. I had to replace almost 4 quarts of oil.
My 2011 GMC Sierra was worked on 3 separate times to correct this misfire. Less than 36k they replaced a burned plug. Around 60k replaced valve cover and same burnt plug. 105k they replaced the burnt plug again. The tech put on the service document the only way to correct the issue was to replace the engine which GM was not going to cover.
POS engine and customer service.
I have a 2007 Suburban LT with the 5.3L V8 and the 8 cylinder to 4 cylinder switching. 201K miles but no excessive oil burn issues. I ignore the computer oil use indicator; and check the dipstick regularly. Change oil every 3K to 4K miles with a synthetic blend. There is one cylinder valve lifter that ticks when cold, but goes quiet when engine warms up. The tick sound relates to the lifter relay that activates/ deactivates the cylinder during the 8 cyl to 4 cyl cruise operation. Only one major issue was the original cylinder head gaskets allowing coolant into the cylinders. This was a known problem at GM, but I had the head gaskets replaced with the updated replacement gaskets at my cost at 150K miles. No problems since. Overall this engine has worked well. I’ m an old school shade-tree mechanic so my vehicle care habits lean towards regular engine checks.
2015 Yukon xl Denali 6.2 They covered piston and rings replacement about 1.5 years ago. Low engine oil light just came on again the other day. I went to the dealership and they were like oh well sorry you’re out of warranty. Sounds like a known problem, did the bare minimum and now I’m out of my powertrain warranty. Gee thanks
Parents own a 2009 GMC. It burned all the oil in one week. They drove down from Richmond to Roanoke VA. Drove around all week. When they went to leave the oil light came on. Craziest thing I have ever seen. I could not believe the stick. When we pulled the plug it was damn near empty. It uses a quart about every 3000 miles normally. GM, you have to do better. SMH.
My friend has an 07 GMC with the 5.3 Vortex with AFM. He started to get some fouled plugs on the deactivated side. Burned excessive oil. He researched the issue and found the problem was with the AFM. He ended up buying something that plugs into his scan port that will turn off the AFM. He installed that over two years ago and has not had a fouled plug since. Look into this. Not sure what he called it.
This oil consumption problem was also happening on my 2010 2SS Camaro. I had to fight with the dealer to acknowledge I had a problem. Then the dealership conducted a twelve month oil consumption test. I checked into the dealership each month for almost an entire year to find my engine down two to three quarts of oil each month. Then they wanted to replace a part that supposedly fixed the problem. I refused the repair and gave them the alternative to check the rings and pistons for damages since they kept running my engine down on oil for the year.
When they refused, I told them I would drop the car in the lot and hire an attorney. It took almost three years to solve the issue. Really sad how big business can now operate without impunity, knowing how difficult it is to fight them in court.
Blanca, we have the same problem with 2009 Tahoe
Same 5.3 what can be done to be part class action lawsuit
It’s there V6 as well. They burn through oil like crazy and NO it doesn’t smoke while doing it. Just magically consumes a quart every 800 miles. Ford has the same issues with there 4cyl. American manufactures never learn. I’ve been primarily a Chrysler/Doge guy all my life and never had issues with any of them like I have with GM and Ford. BUT, If my 2018 Hemi swallows it’s camshaft I’ll switch to Toyota.
My 2010 suburban uses oil also. I have a buddy with a 2008 his does same thing.
My 2011 silverado using oil constantly. 105000 miles on it replaced plugs twice in last 40000 miles . How do I get into this suit
FORD HAS THE SAME PROBLEM WITH THERE 2 VALVE 4.6L MINE DOESNT SMOKE OR LEAK BUT I HAVE TO ADD A QUART ABOUT EVERY 1000 milesI HAVE A 97 GRAND MARQUISE LS WITH LOW MILES
I think it’s horrible how american cars slip thru the cracks of what should be recalls. It’s obvious politics have and always been involved. You’ll have to buy foreign cars, as america likes to recall and keep them on there toes to insure quality and safety. It seems the only answer but it is so unfortunate.
My 2011 Tahoe is currently doing the same I’ve replaced the oil pressure sensor two times how can I get into this class action
I have a 2010 Equinox that magically consumes oil steadily but doesn’t smoke at exhaust.
Never again GM!!
I have learned my lesson on.the sneaky GM tricks. General Motors been making cars for over a hundred years they still can’t get it right I’m through with them you should be to move on. My next vehicle definitely Toyota a company that stands by its vehicle Manufacturing and has a great track record
Regrettably I have a 2010 Equinox that magically consumes oil steadily but doesn’t smoke at exhaust.
Never again GM!! I’ve learned my lesson with the GM trickery never again GM .
General Motors has been building cars for over a hundred years but they haven’t got it right yet simply pitiful!
Next will be a Toyota they have a reputable history up taking care of their customers and they build great Vehicles I’ve learned my lesson with GM never again !!
Do people read and understand what is going on with these engines, or do they just want to reply with ignorance, T he problem is multilayered. DOD, Piston rings, PVC placement.and so on. Not a maintenance issue.
My 2009 silverado 5.3 has the same problem it’s going to cost me 3 to 4 thousand to fix it not happy
My 2009 chevy silverado has the same problem it’s going to cost me 3 to 4 thousand dollars to get it fixed not happy about it
Well well here we go again. Regrettably I have a 2010 Equinox that magically consumes oil steadily but doesn’t smoke at the exhaust.
Never again GM!! I’ve learned my lesson with the GM trickery never again GM .
General Motors has been building cars for over a hundred years but they haven’t got it right yet ,simply pitiful !
And they scratch their heads and wonder why they are losing market share year after year !
My next purchase will be a new Toyota ,they have a reputable history up taking care of their customers and they build Great Vehicles !!
GM’s problems are mainly the exorbitant wages negotiated with the ruinous Labor Unions and the ridiculous Federally forced Affirmative Action BS in the engineering and design depts.
Tens of thousands have had enough and learned costly lessons with GM , so never again !!
please stop the flood of emails.
So Kurt,, exactly what does affirmative action have to do with engine oil?
These problems go all the way back to 1999. Lol mine has 275k I am always adding oil.
I have the same problem with my Trailblazer 2002 with a Vortec V6 I only have 80000 miles I’ll been adding oil for 18 years, the Chevrolet dealer told me that’s normal
I have a 2009 Silverado that uses plenty of oil and also a 2004 cadillac srx and the 3.6L is horrible with the same issue except the air cleaner gets drenched in oil.
I had a 2001 GMC 1500 with the 5.3l it had to have a whole new engine before 3000 miles. The new crate engine sid better but it still burned oil
That was how I kept up with oil changes. The oil light would come on and it would be a quart or two low. When overdrive kicked in a puff of smoke would always blow out tailpipe. Valves knocked the whole time I owned it.
I have a 2007 gmc yukon xl, it has had an oil consumption problem since I have owned it. It is a well documented problem with gm turning a blind eye. Would have hoped 5hat they would have stepped up with options to help with the obvious problem.
My 06 envoy denali has this issue…2 qts added in 5000 miles. Moore GMC told me to change driver side valve cover as issues with pvc are integral built into the cover…oil still fouls #8 cylinder plug @6000 miles. Why does gm build a motor you have to tear into to change the pvc valve…Engineering fail!!!…
I have a 2015 yukon and has this issue as well, have to add 2qts between oil change.
Man, this topic has seen the most response of any in a long time. Hope GM is listening. If this many 5.3’s are this bad. They better brace for big fight. Just hope the Lawyers know what they are doing. Again, get the Range Tech AFM delete module. It works!!!!!!!!!!
I have an 81 Chevy C-10, 350, 5.7 Vortec Heads, Edelbrock intake manifold. Original Engine, using synthetic oil. I change my oil every 5k miles whether it needs it or not and it’s usually down about a half quart. What has happened since the “Old School technology “ and today?
2007 Tahoe, same issues as everyone else and this site is claiming. Low pressure, always 2 quarts low between oil changes. I had engine top end rebuilt twice! Poor engine design
Boy oh boy! I’ve owned a 01 Silverado HD LS now for 20 years, and it has 279thousand miles & I’ve always had to add oil, check engine light warning!!! Low oil light, Man I tell that’s you that’s the way to go G.M motors, so much for loyalty to customers who support GM product!
what about 06 monte carlo ss,it should be included.mine uses oil because of the active fuel management
I have a 2008 gmc sierra 1500 slt with the 5.3l with 190,000. I have had it for 3 years and every oil change is 2 quarts low and because of these issues i have had to replace lifters 3 times and change the oil pressure sending unit. So what about us with older models that do the same thing?
This is the biggest reply since this forum started. Many different views about the problem. Some great, some just plain idiotic. But to the people writing them, they are important. The real issue, is GM trying every trick in the book to improve the CAFE ratings. Most don’t work. They just cause issues for the owners. Then GM, won’t fix them. They just ridicule the owners for poor maintenance. That’s just so wrong. Just build the things right. And quit giving loyal customers, such a hard time. GM will chase these people away, sooner or later. Maybe, just maybe, GM is watching this forum, and will heed just some of what is being said. I’ve been a loyal Chevy owner since 1967. I would like to keep being one. Lets keep on GM, to just make things better for their customers. We can only hope!
I had an 08 Silverado with a 5.3 liter vortec. Lost all oil pressure and Stanley Chevrolet in McCordsville said they couldn’t find the problem to fix it after they charged me $700 to replace an unbroken oil sending unit. Lost the truck due to repo, it not being able to be driven and still owed money on the loan. Can we get the lawsuit to include 08 year silverado’s? If not, this is b.s.
Best thing you can probably do is stop buying GM and get a Lexus/Toyota. Its not just the 5.3L engine that they are having problems with, seems they are facing a lot of class actions suits for all kinds of things. Engineering at its worst. With the money we spend on these new vehicles you would think you could buy with no regret. This is not the case!
Basically I see people commenting and saying its the owners responsibility to check their oil. Well duhhh.. but its not normal to have to add a gallon of oil between oil changes. My guess that’s the GM engineers commenting stupid comments.
If ..we didnt check our oil.. the engine wouldn’t make it to the next oil change. FFS this is what 80k buys you from GM
I had the exact same issue. We had to replace the engine in November 2020.
2001 gmc HD 2500 owner / life long mechanic for more than 35 years. I bought brand new in 2001 and have hade the same issues as stated by almost all posts on this page. I am a proud owner and a believer in general motors products, but yes I’m afraid of having a huge premature problem and expense with my truck.i can only hope that G M will cover any major problems that myself and others may or will experience in the future. I hope the (Higher-Up’s) at GENERAL MOTORS reads this and supports and honors all of its customers as a upright and respectable company to the owners of their products!!! Remember CUSTOMER SERVICE IS THE BACK BONE TO ANY COMPANY. customers will stay safe and satisfied with their huge investments and continue to be loyal and purchase new G M products when it is needed.Thank you G M for your consideration, and please keep building the vehicle that the world has trueloved over the many years of production.

Just this morning I had to ad a quart to my 2007 sierra, changed the oil 1500 miles ago. Oil is also changed every 3k with full synthetic. What a disaster the AFM engines are. I have already replaced failed lifters and the AFOM. If I buy a truck with a v8 I expect a v8 at all times. Hopefully this lawsuit Gaines some traction because it is needed.
Mines a 2012 Sierra and is in the shop due to the same issue been a life long gm guy but probably going to sell and go with a ford with the powerstroke🤬
Did you use an afm disabler? How many miles on your truck?
Jim, I’ve noted this disabler before in earlier posts. It’ the Range tech. plug in. It’s around $200.00! It can be found on the web, just about anywhere. Summit also sells them. It’s simple and it WORKS. Just plug it in, and your AFM is now deleted. I love it! Our “12 Tahoe has about 85, 000 on it. Started lifter clack, around 75,000. GM laughed at us. Told us we used wrong oil! BS. Did some research, and found we were not alone. Found Range Tech. Bought one and it works. “Bout all I can say. Get one, and you will be happy again.
I have not and my truck has 109,000
Very happy that you have not had any AFM problems. Believe me, you are the exception, not the rule. That’s why there is a class action suit. This reminds me of the late ’70’s, early ’80’s, when GM used bad cams in their small blocks. They made owners pay to rebuild their engines. Until, a class ation suit, proved the bad manufacturing of the cams. That’s what this action will hopeful fix.
I was just asking the gentleman who had his engine apart if he had one. I do have on and like you love . Also have the new drivers side valve with the new pcv placement and drain rail.
Its very cheap to fix the oil problems if you know what to do. My 2007 silverado was burning 2 qt after 900 miles. About a half a qt in the intake when i dumped it out. This was the fix: 1st. In the oil pan there is a blow off valve. It needed a deflector shield that it wasn’t originally equip with. About $5 This keeps the oil bleeding from hitting the connecting rod which creates excess oils mist. It directs it down and away from rotating assembly. 2nd the passenger valve cover has a breather port right over a rocker arm. This needs to be welded closed and moved to a spot in between rockers. The rockers squirt oil right into the breather port. Free if you can weld aluminum. 3rd. Because the piston oil rings are probably stuck from the excess oil mist they have to be cleaned. GM has a product that is about $25 that you put in the cylinders for up to two hours that complete cleans the carbon out of the rings.
I have 2021 Silverado with 5.3 Eco engine. At 371 miles the engine failed because of brooken spring in the piston shaft. Full engine replacement from G.M. Infortainment system failure at 290 miles delear could not duplicate the problem. Partial radio failure at 400 miles dealer could not duplicate. Full blow out of all the fuses at 450 miles. Dealer replaced fuse block and all fuses. Also service tech drove the vehicle with me on return from fuses problem and radio failed before we got out of the lot. Dealer installed new radio after ordering at 450 and replaced at 500 miles. Partial radio failure at 550 miles so I am not video taping all starts and stops with my cell phone. Problem did happen one time during recording so I am going to keep recording until I have a few recordings on different days with different weather.
can i refill trulieve vape cart church
I have a 2010 silveraso with 42300 miles and it burs oil and the trucks shakes until I give it some more rpm’s everytime I start this. This should not be happing with only 42300 miles. I think an engine should last longer than this. This has a vortex 5.3L engine. I want some justice.
So where does this lawsuit stand as of now?
I have a 2013 black diamond avalanche with a 2nd new oil preasure sensor and the darn thing turned on again today. Oil is fine my gage says I have preasure, it’s not burning it , I’m not leaking it and the coolant is clear…….any thoughts?
My 2014 Silverado (while under extended warranty) has been religiously serviced by the Chevrolet dealership since it was new. Within a few days of a new oil change the check engine light came on and the display indicated low oil level. When I pulled the dipstick there wasn’t any oil to be found on the dipstick so I had to go to the store to purchase 5 quarts of oil for it to show up on the dipstick. Took the truck to the dealership and told them what happened. Was forced to go months doing an analysis. Now by this time the extended warranty had expired and I was told there wasn’t anything they could do and that the truck wasn’t in their opinion burning oil excessively. Since then the oil level has gone below being seen on the dipstick several times. Great for Chevy since my truck is no longer under any kind of warranty and bad for me because I can’t afford a rebuilt engine. I don’t know if I can ever trust GM again for such a poor engine design or perhaps a disgruntled employee taking it out on potential buyers like me.
I have the same oil burning problem with my 2012 equinox, have to check it after 300 miles…135k miles…
My Hyundai 07….I don’t have to even think about it between oil changes…
