A recent class action lawsuit filed in the U.S. District Court in Ohio claims General Motors‘ 5.3-liter LC9 V8 engine burns high amounts of oil and has other design flaws that could lead to engine damage.
The suit alleges the 5.3L V8 engines found in a number of 2010-2014 model year GM vehicles have flawed piston rings that don’t maintain tension well enough to keep oil in the crankcase. Additionally, the PCV system may vacuum engine oil out from the valvetrain and expel it into the intake, where the oil is then taken in and burned in the combustion chambers.
The active fuel management compounds the oil burn problem, as well. The system uses an oil pressure relief valve that sprays oil directly onto the piston skirts, but this oil spray can allegedly overload the piston rings, leaking past the rings and burning off, or accumulating on the surface of the combustion chamber and causing carbon buildup. Furthermore, the plaintiff says the oil monitoring system will not inform the driver about the low oil levels, so some owners may not be aware when the engine runs low on oil.
These issues can lead to spark plug fouling, ring wear, lifted collapse, bent pushrods, camshaft wear, valve wear, rod bearing wear, rod breakage and other major failures in the engine, the class action suit claims.
According to Car Complaints, GM told dealerships to carbonize the rings and combustion chambers of affected vehicles, but it did not remedy the problem. GM also apparently knew about potential problems with the engine as far back as 2007, based on consumer complaints and Technical Service Bulletins it issued. The TSBs indicate the problems are caused by PCV issues, piston rings and the active fuel management system.
GM redesigned its 5.3-liter V8 engine after the 2014 model year, using redesigned piston rings and adding a shield to deflect oil away from the piston skirts. The newer versions of the engine also feature an oil level sensor and new valve covers. Vehicles involved in this class action were all built between 2010 and 2014. They include:
- 2010-2013 GMC Canyon
- 2010-2013 GMC Savana
- 2010-2013 GMC Sierra
- 2010-2014 GMC Yukon
- 2010-2014 GMC Yukon XL
- 2010-2014 Chevrolet Avalanche
- 2010-2012 Chevrolet Colorado
- 2010-2013 Chevrolet Express
- 2010-2013 Chevrolet Silverado
- 2010-2014 Chevrolet Suburban
- 2010-2014 Chevrolet Tahoe
The plaintiff in the lawsuit is looking to represent current and former owners or lessees of affected vehicles in the United States that have experienced similar problems. The case is Szep v. General Motors LLC (Case No. 1:19-cv-02858) and was filed in the U.S. District Court for the Northern District of Ohio.

“ Some owners may not be aware when the engine runs low on oil“
Sounds like the dipstick is not checking the dipstick.
When GM goes bankrupt the next time, remember it was do the fact that in order to get customer support you had to sue !
In my opinion.
GM after all has ZERO customer support !!
I’m curious.
What in the terms of this case is excessive oil use.
I see complaints on oil use where some are less than 1000 mile and some complains one quart in 6000 miles.
The main issue is the PCV system as it will suck up some oil. GM has install a new box on most engine that works as a catch system that puts the oil back into the oil valley and engine not the intake. Wit DI it has created carbon issues on some intake valves on some engines. If driven hard it is not as much an issue but if just putting around town it can build up.
Running low on oil should not be an issue if you check it as recommended since this engine runs on 6 quarts of oil.
On the other hand carbon could be an issue.
All engines use a bit of oil. This is how valve guide are lubricated. But depending on the engine adding a quart may at may not be normal.
In the old days most engine leaked a qt about every 1500 miles in most engines.
I own a 2011 GMC Sierra 1500 Crew Cab. I just rece6had to replace the oil pump due to the pressure relief valve sticking in the open position thus causing very minimal oil pressure. Maybe had two to three psi on oil pressure and alarms going off on instrument panel. Started the repairs by removing oil pan to get to the o-ring on the pick up tube. That didn’t fix, changed Sending Unit relay and still no deal. So hardest last and it ended up saving me probably close to $3000 in parts and labor costs. If I would qualify to be involved in this suit let me know.
GM and their continual issues. You would think that a company that is so obsessed with selling trucks and SUV’s would at least make some attempt to improve quality since this is soon all they will have. Yet here we are with oil burning 2.4’s, 5.3’s, 8 speed automatics with shift quality issues, troublesome 9 speed automatics, recalls, vibrating Silverado’s and Sierra’s and the list goes on and on.
Oil consumption should have been an issue solved. 60+ years ago. Any engine burning excessive oil in 2019 is POORLY designed.
If GM is too stupid to get a v8 right after putting the first push rod v8 in a everyday car like the 55 Chevy they deserve to go broke and not be BAILED OUT AGAIN
I have a 2013 Avalanche with a 5.3 engine. Between oil changes the engine will burn a little over one quart of oil. I use a full synthetic oil and change oil when the computer says to change oil. I have three other GM vehicles with different engines that do not burn any oil. In todays engines with tolerances that the engines are built to there should be no oil burn. So for an engine to burn this much oil over approximately 6000 miles means something is wrong. It is no big issue adding the oil but the concern is what happens over say 250,000 miles. I now have 100,000 miles on the engine and there has been no change in the oil usage since the day I got the vehicle. If it continues this way for another 150,000 miles it will just be a nuisance but my concern is that it could lead to a major repair.
i would not listen to the oil minder 6 months 6000 miles
I bought a 2014 chevy tahoe 5.3 with 98K miles and they had just done an oil change buy the time it got to 15% oil life my low oil pressure light came on and i checked it and the dipstick was dry. I added 3 quarts of oil and got to the right level but, 3 quarts of oil. Went to the dealer to get an oil change and checked it before leaving the lot and it was full. Im at 75% and its already a quart low. Is there a recall or is there a legal action i can take?
Literally sounds like people don’t know how to change their oil before or at three thousand miles or don’t know how to look at their oil pressure gauge lol and it takes 10 seconds to check the dip stick before it gets to low. And if your burning to much oil because it’s going past the rings it just sounds like you need some new Pistons
Lol – when an engine consumes oil you have a problem, regardless if you change your oil every mile or every 3000 miles.
first of all it takes full synthetic dealership recommended 6000-7000 between oil changes.and u said new pistons lmao. my truck is a 2018 with 26000 miles and your saying it needs pistons lol ur an idiot
I bought my 2001 Tahoe with the 5.3L engine new and have personally changed the oil religiously every 5000 miles. I use only Quaker State 10W-30 MOTOR oil – no synthetic here, and from day one, I pour 6 quarts in and only get 5 back. Some might say that the extra quart is in the filter, but I pierce the bottom of the filter prior to removal to aid in drainage, so the filter is empty when it comes off. On the rare occasion that I miss my 5000 mile mark, the message center has come on between 5500 – 6000 miles to let me know the oil level is low. Checking the dipstick reveals it’s 1 quart low. I now have +408,000 miles on this truck and the original engine is still running as strong as ever. I don’t know about the newer engines, but the older 5.3L V8’s are bullet proof.
How do I get on board with them to file a suit, I just recently had to rebuild my engine because of this
Intersested. High oil use and repeated plug fouling due to bad rings (#7 cyl)
How do I enter this claim? 2013 Silverado, high oil use, repeated fouling of plug(#1 cylinder)
i have a 2007 gmc yukon xl 5.3 motor bad com bad lifters it going to cost me 5.000.00 to repair gm sucks
My ’13 Silverado does up to 7500 miles between oil changes, going by the OLM. The OLM does not check oil level, you have to do that yourself. Generally uses 1 quart in the OCI. When travelling and driving hard, may, but not always, uses about 8 ounces per 500 miles. I can see people having a low oil problem if they never check the oil.
My 2014 silverado burns approx 1 to 1.5 qts of oil in 4000 mi.
I have to add oil periodically.
Yes the same answers I get from the dealer , my oil consumption is just short of what the service bulletins show.NICE JOB GM
Of Course GM engines burn oil. Been that way since 1955 and the original SBC. Rather have a Chevy than a Ford. “Chevy” “Can Hear Every Valve Yacking” “Ford” “Found On Road Dead”. Your choice. Rather hear valves tack then be on the road dead.
Chevrolet = Shove it or leave it.
GMC = Garage Mechanic’s Companion.
Ford = Fix or repair daily.
How about the cracking dashboard they won that one also
2008 GMC Sierra uses 4 qt out of 6 EVERY 5000 MILES no leaks no smoke
My 2007 Silverado burns about 1.5 qts every 2500 miles. I check my oil often for this reason, and watch my gauge. Why is this Lawsuit limited too 2010 and above if they knew in 2007? Also have a recall on a Airbag, they they still havent fixed.
How about the cracking dashboard
GM knew there was a problem in 2005 when I was taking my 2004 Silverado into the dealership for using and burning oil. GM claimed at the time that the motor had a cylinder with all the rings were aligned causing the oil problem and it would fix itself during the time of documentation the dealership closed and the records were lost. I still own the truck.
2009 Silverado 5.3litre never added oil between oil changes always at or above add when I change it and up to 16000km between changes always used full synthetic now has 185000km and never had a hiccup.
How does one join this lawsuit? I have oil burning like crazy. I add roughly 4 quarts full synthetic between oil changes. It’s only time before this truck dies.
Hi i got 2015 Chevrolet Silverado 5.3 comeing home it with in limp mode temperature pig out water in oil take intake hose off going air box full of oil running out sound like something bent in head spark plug back out one time only got 71000 mile it could been bulit in 2014 thank you randy Wells
I have a 2014 silverado with the famous 5.3l with fuel management.
And it uses oil 3/4 at in 3000 mi.
Just under GM specs now at 96000 mi.
All the dealer does is NOTHING BUT DOCUMENT
I would suggest you learn how to write before you worry about why your “pig is out of water”.
This is why I always run an oil catch can,duh.At each oil change I open the catch can container and it is always full,which is a 3oz. capacity.3 ounces might not seem like a lot but in the intake manifold and combustion chamber it’s a ton.The only thing allowed in a combustion chamber is air,fuel,and spark.The addition of oil increases the internal temperature and causes carbon build up on valves,etc.With ANY GDI engines this happens,some are worse than others,like the Hemi engines which typically expel 6 ounces per change interval.The valves are no longer being cleaned by fuel with particular regards to the back of the valves, meaning that all those cleaning agents that fuel makers claim are mostly irrelevant in GDI engines.Some vehicles are coming out with port and GDI,which is an admission to the GDI side effects.The 2019 Corvette ZR1 and Mustang Shelby GT500 have both.This will set off law suits against all GDI engine manufacturers, regardless of brand.
catch can recommended seafoam makes a do-it-yourself preventative valve cleaner or see your dealers service dept.
How do I enter into this lawsuit it is not only that year model I have 2008 Chevrolet Tahoe and it has all of the same issues the oil
Just disappears I have had to replace my engine and still the same. I live in Georgia but the money I have spent on oil and engines and trying to get it fixed I could have bought a new car by now. Also anyone I know driving a 2008 and up flex fuel has this problem
What system are you using can you send me a link
Explain why I have a collapsed lifter, potentially bad piston rings and had a bad oil pressure sensor? I checked my oil twice a week on average and changed my oil every 3,000 to 4,000 miles. I get that the oil pressure sensor will always go bad, but what makes that okay? You cannot prevent that. Just like the problem with the cylinders used during AFM misfiring due to (usually) a collapsed lifter. This is something you should not have to monitor. I got a misfire on 4, stabilitrak light and traction control light. Changed my oil pressure sense and checked the spark for 4. All issues caused by AFM and its issues. This weekend I am going ro try and free up the lifter and hopefully it works; otherwise, I will be changing it.
So, place blame on GM. Especially, since they knew it was an issue all along. They tried to fix the issues regarding this in new trucks without disclosing there ever being an issue. Seems like a cover up. But, yeah. The thousands of people complaining about the same issues must not have been checking their oil.
see youtube on how to free up lifter if it frees up you must disable AFM changing lifters requires pulling heads
I have a 2018. 5.3 Sierra. Dam thing burns a quart every 2000 miles. Tully GMC tells me this is within the allowable range. BS. Oh ya So I asked the tech what my oil pressure should be Hie answer. Any were between 0 and 80. ☹️ Such BS
Melling makes the lifters and claims they are not the issue.The issue is oil blow bye which turns into carbon and sticks the lifters.One hiccup in valve train is devastating.I saw a 2015 Silverado with a 6.2L with 140,000+ miles on it come into a shop.It had a flat cam which was caused by a stuck lifter that was stuck by carbon,made by the oil blow bye.The invoice was around 2K and an oil catch can is $149 at JLT Performance,just saying….
How do you join the class action lawsuit
google the subject and contact the attorneys office surprised they have not found you have been getting junk mail from them for a good 5yrs
We are currently in the process of having to get my 2012 Chevy Silverado engine fixed due to this issue. As everything we have read it cylinder/lifter #7 and most likely the camshaft. My truck only has 115,000 miles and has never missed an oil change and had zero warning of having issues. We also have a 2011 Chevrolet Suburban with the same engine at 91,000 miles so we are panicking that this will happen again! Something needs to be done immediately about this!!
Dylan, again…GDI engines for all manufacturers have an oil consumption defect by design.Older engine designs dealt with blow by in different ways but in GDI it puts it back through the intake manifold and throttle body.This causes an excessive amount of carbon build up and eventually chunks and bits break loose and stick a lifter.As for the rings as the oil enters into the combustion chamber and it should never be there it raises the internal temperature and causes premature wear and tear.It’s as simple as that.You can find comments on all manufacturers that have a forum and see for yourself. Melling makes the GM lifters and made a public statement as to how it isn’t their products that are to blame.Basically the hot rodders are generally ahead of the game with engines and they came up with the oil catch can and it works to keep the oil blow bye to a minimum.It is the best anyone can do with a GDI engine.FCI(Chrysler) engines have more blow bye and they have lifter issues to,so should everyone sue them too?Where does it end then?
I have been running the 5.3L and 4.8L V8 for years.No oil consumption at all.I use an oil catch can and it saves the engine!I also use Supertech oil from Walmart (Exxon Mobil oil!) synthetic and Wix filters, again no issues.GDI engines from all makes have the blow by,so pony up a little money for a catch can and there you go.I change my oil every 5K.It doesn’t matter what company-GDI engines just do this. It does help if you go to a trusted shop and get the BG Products line of GDI help,it has an engine oil treatment,fuel system flush,and an engine cleanser to get out the carbon garbage from the blow by.After that install a catch can and you will not have to worry about it again.I generally have 1-3 onces of oil in the catch can cannister at each oil change interval.That would be going into the engine if not for the catch can and causing issues.Just saying…
I have a 2007 that burns a quart 1/2 every 1500 miles…I want in on this suit. Mine is a 2007 and they know they had problems back then so suit should include all 5.3. How to extend it?
Not sure how old this is but I have the same problem I have a 2010 Silverado 5.3 and it literally burnt to nothing and was smoking I have to rebuild my engine
My current 2014 Silverado 5.3 is loosing oil, with no signs of oil leakage . I add 3qts between oil changes
sell
I have a 2009 Chevy Silverado 5.3 that the lifters are going out every 1,000 miles for a total of 8 times now and this has cost me thousands of dollars!
Oil catch can is what saves the GDI engines, after damage and an engine change get one so it doesn’t happen again.
I have the same issue on my 2011 Chevy Tahoe. Anyone knows what can be done. This is frustrating and expensive been up to date with maintenance and buying quarts of oil to refill. Spark plugs being replaced due to the oil getting to them. Mechanic shops can’t see the problem as no signs of oil leaks.
I am having same issue with my 2011 Chevy Tahoe. I have put a lot of money in this year in to my truck but still having this issue. I am tired and I can’t afford if my engine gets damage with the COVID-19 crisis that we are facing. What can be done if dealer can find this issue and not doing anything in regards to this settlement issue?
Can anyone tell me what law firm and wheree is handling the class action law suit???? We are having this same issue
I have a 2013 Chevrolet 1/2 ton 5.3. 110,000 miles. Change the oil on a regular basis. Always have check my oil just in case there’s a leaking filter. Which is common. Its been using oil for sometime. I’m Wondering how serious it’s shorting the life of the engine. Major problems soon you think? I would like to trade before the major cost.
I would like to know how I can join this lawsuit to I have a 2012 Chevy Silverado oil on spark plugs how to change spark plugs every 7 months if not sooner if not sooner
I also would like to know how to join this lawsuit. I have a 2011 silverado that is burning oil like crazy. 70percent left on oil life according to the gauge. But, the oil level isn’t even touching the dipstick!
Several people have asked how to join the lawsuit but nobody has an answer.
I don’t think they have fixed the problem I have a 2017 and it’s doing the same thing.
2013 Silverado 5.3 ..Continuous.Oil consumption, Fouled plugs,I would like information how to join this class action Lawsuit also…Texas
2012 Sierra. I had to replace my engine due to a lifter failure. Dealer said it happens all the time due to the automatic fuel management system building up carbon.
I would like to join up on the class action my 2013 just died engine no oil???
I have a 2010 silverado that used to burn oil like crazy and I believe it still does to a point. I ended up changing the driver side valve cover ($20 fix that took 20mins) which helped with the oil blow by into the PCV valve. The new cover has a different size baffle that doesnt allow oil to build up in your valve. I used to get a puff of smoke on my start up that would go away after the oil burned off. Change this part and you will be amazed. I feel that this should be something that GM should cover but I would recommend anyone with the 5.3 AFM engine to look into this. I continue to change my oil every 3k miles and add a lucas oil stabilizer to help with upper cylinder lubrication. I now have 190k and seems to drive fine. If I could just stop the stupid rust from the rear wheel wells I would be good to go. Hope this helps someone frustrated dealing with something that nobody seems to fix eventhough you spent tons of money taking your vehicle to the “stealerships”
Can I join a lawsuit in the states if I’m from Canada ?
I have a 2013 Suburban and it’s consuming oil at a rapid pace. I want to address the issue before it turns into a major repair bill.
I have a 2013 suburban. @103,000 I noticed excessive oil consumption. Not very knowledgeable about engines but for now I installed a Range device that stops it from going into AFM mode. Getting ready to install an oil catch can and hope to make it last for now. I’m a 3rd Gen Chevy man so I wish Someone at GM would own the company and fix this issue. It’s a dream.
It says they were aware of the problems with the engine going back to 2007 why aren’t they including all cars back to 2007 in a suit
I have a 2008 Yukon that the engine has been rebuilt, and the AFM is messing cylinder #4 again. Any help?
Seems to me this GM authority is bunch of BS….I left A comment about my 2013 Silverado burning oil and fouling plugs…..and plainly ask how to join this class action Lawsuit..and never got not one response back…and for your Vehicle. Get a Range AFM Disabler. Or Diablo sport AFM Disabler Change your Spark plugs.and try that..I done this to my Silverado seems to be helping so far…Good luck…
I have a 2017 Suburban 5.3 engine and it is in the shop for the second time. This time it’s the #2 plug at 28,000 miles the #1 plug went 3 months ago. I am presently in the DIRTY FIX IT dance with the LIARS in Autonation’s service department, very deceptive and sneaky people. Despicable behavior you would expect from CRIMINALS! These engines are a disaster!
I am having the same issue my plug #6 went out in less than 4 months I am getting oil in them. This is so frustrating😡
The 5.3L engine is a great one.Get an oil catch can and all is well.$149@JLT Performance saves any GDI engines.Oil blow bye which is natural on GDI engines gets put back in,only it causes corrosion and carbon build up.This starts from the first time it is turned on.I don’t have any engine issues with my 5.3L and 6.2L LT1 because I am an educated car guy.That is how dealerships get you,by not doing your homework.Ram,Ford, Toyota,Honda, Nissan,etc. all have these same issues with Gasoline Direct Injection engines.The oil catch can is the best way to go,it catches the oil and you empty at every oil change.Also I don’t let anyone else change my oil,I control the brand of filter(Wix) and the brand and type of oil, synthetic instead of the semi synthetic oil that dealers use.This has made a difference in my experience.Sue all you want,it still won’t change the nature of the GDI engines.
Does it have to be the 149@JLt?
Google 12-06-01-001. There you will find out there is a service bulletin on the issue we are having with our GMC vehicles. Hope it helps anyone.
2013 GMC Sierra using a quart of oil every 800 miles less than 50,000 miles can fighting this for over a year replace valve cover didn’t change a thing
I bought a 2013 suburban from a Chevy dealer not aware about the excessive oil consumption. I change my oil every 3000. When I checked the oil holy mole it was 2 quarts low approx. AFM is a flawed design. At 120,000 miles all I could do is install the Range device in the OBD connector. I hope Chevy owns up to it. I also have a 2008 Honda Accord and it too had the same issue with excessive oil consumption. Honda owned up to the problem and settled in a class action suit. The Honda dealer did a rebuild free of charge.
Just want to clarify that according to Honda only the the ones built in USA have this problem. Not the Honda Accord Japanese imports.
2013 GMC 5.3 used 2 quarts of oil in 3000 miles, tooked to dealer, asked about the problem, denied knowing anything about it. But they would charge me by the hour to investigate. Replaced drivers side valve cover didn’t help, also fouls out I believed number 4 spake plug. If there is a class action sue how do I join
Chevrolet has a problem with internal oil burn on ALL its engines and to fix ALL the internal problems it would take redesigning the engines top to bottom. So Chevy is slithering back to the good old 70s and 80s play book and just DENIAL DENIAL DENIAL! They play like the GOVERNMENT, STUPID!
Can you still get in to the class action law suit
I you can leave comments on this website to vent, that’s about as good as it gets, can’t get any information about joining the lawsuit
No,the lawsuit has been dismissed by a federal judge.
All GDI engines have oil consumption, it’s not specifically GM, it’s all manufacturers.Know what you are talking about before you speak.Oil blow bye occurs naturally in all engines.The older engines took care of it with baffled valve covers and breather system.The GDI engine has the spark plug,fuel injector, valves and piston all in the combustion chamber which is different from older designs.This doesn’t allow the valves to be sprayed with fuel and when oil vapor enters the chamber it raises the temperature in it and carbon build up forms on the valves and the top of the piston.Oil is redirected by pcv from one side to another and back into the throttle body and then the intake manifold.This is the problem and only an oil catch can is the answer.It simply catches oil vapor in a canister connected to the pcv system and you empty it at each oil change.It is quite simple and I have them installed on my 2 vehicles and it works awesome.No oil consumption on my engines.Also it helps to use full synthetic oil and not the semi synthetic oil.
Yes Blow by will occur and all the engines 2 quarts in 800 miles that’s a little excessive had a 2004 Silverado 5.3 never lost a drop in 5000 miles between oil changes so go get your check from General Motors for the post to you’re making because what you’re saying is technically correct all engines do have blow-by but give me a freaking break
Ordered a oil catch system, haven’t received it yet. Also put two cans of Berryhill fuel injection B12 cleaner, truck is running a lot better
I don’t work for GM,I just know how it works and how to get around the issues.You can try the product “Restore”.I have had success in the past with it,it has ingredients to fill in the pits and scratches of the cylinder walls.However without the catch can installed you are just repeating the same process.It’s only $149@JLT Performance,you can hit that at 2 quarts at a time in short order.
No Summit Racing and Jegs sells them also but JLT Performance is the manufacturer.There are others that make them but for $200+ and not made any Amazon sells them for like $24+ but more of a universal fit,JLT is exact fit right down to the factory pcv connection.
Any better…phone messed up.
I have 2005 Chevy Silverado 5.3 vortec bought used had 22 thousand miles when I purchased it had oil consumption problem since didnt get all these bulllitens new valve cover on drivers side not helped a bit now im down to remanufactured heads sending off today to get rebuilt new gaskets it’s been nothing but a hassle since I’ve owned it I love my truck new transmission all new plugs wires coil packs fuel injectors evap I’ve been chasing a p0300 random misfire for two months it’s been onthi g after another since I’ve owned it new fuel pump numerous wheel bearings shackle broke bar across under gas tank completely rusted away
Had an 06 Silverado, 5.3… Used 1.5 quarts every 5k. Had the truck 235k. That was the only issue. Bought a 14 Silverado, 5.3… Started to use 1qt every 5k… at 75k. Dealer said 1.5qt between oil change is acceptable. BS. Maybe that’s why they went from 6qts to 8qts. So I found the fix to my problem, I bought a 15 Ram w/5.7 hemi. Uses no oil. Zero. Zip. Nada. 7qts in, 7qts out every 5k. 100k now still no oil consumption. Does not require 0w-20 either.
Sam McEachern, would you please publish an addendum to let people know how to get listed as part of the
Class Action suit? Thanks!
2011 avalanche ,90000. miles, using 1 quart of oil Every 800 miles, no check engine light? Shame on G .M.
Sorry to hear. I installed a Range AFM disabler on my 2013 suburban and it reduced the oil consumption. Getting ready to install an oil catch can.
I have a 2009 Chevy avalanche ,I bought it brand new in 09 have 127,000 miles engine mis firing in#7 cylinder they said engine gone out anybody having same problem
I have a 2019 5.3 SIlverado and burning a quart every 2000 miles. They handed me a bulletin about oil consumption and how it is normal in “some vehicles”. If it is normal shouldn’t it be all of the vehicles?
I could see if it had 80k on it. I would dump it now while used values are high.
Is there a number to call? I have a 2010 Yukon xl with the oil problem?
I have a 2014 Tahoe and it used just over 3 quarts in 3000 miles. No leaks, not smoking, no residue in the tailpipe but I also foul a plug every time for an oil change.
sell now before your putting in a junkyard or rebuilt engine.
I have a 2007 Chevy suburban z71 with the 5.3 and constantly loosing oil . Recently dropped pan and found a lot of burnt oil on inside of pan. And above it .
Sell fast
Please someone let me know how to get in on this suit. My truck is in the shop right now and I can’t afford to fix it or buy another. Help please !!!
My 2008 Sierra LY5 burns 3/4qt per 1000 miles on average. I contacted GM corporate and was told to get an oil consumption test and if a dealership showed I’m burning that much we would discuss options. After 4 attempts of trying to get a dealership to do a competent consumption test they backed up my consumption rate. GM told me my truck is too old so they’re not going to do anything. Then why in the F did you have me running around trying to find a dealership that knows how to do a consumption tests? What a PITA waist of time that was. Anyway, why isn’t 2007.5-2009 included in this? F GM
sell
All due to oil blow bye.The pcv system dumps it into the air intake hose,then the throttle body and intake manifold,then to the combustion chamber where oil isn’t supposed to be.Oil catch can fixes the issue,so does the Range Technology AFM delete.GM isn’t the only car company experiencing this,they all do.Yes, even Toyota.I had a 2010 Silverado and had no issues while doing this,it simply works.
If you catch it early enough it works. If not, your oil rings accumulate deposits and won’t seal anymore. I have a catch can and a range and updated the valve cover. None of it made a big difference. Yeah the catch can caught some oil over a few months but I still burn oil at close to the same rate. If I’d known about all of this I wouldn’t have bought this oil fire.
I have 2012 silverado 1500 5.3 that is burning alot of oil in between oil changes. I check under the hood, no leak, i also check underneath the truck, no signs of oil anywhere. I leave a piece of cardboard underneath the truck overnight and the following day it is completely dry. This worries me alot, how can i get in on this suit?
You don’t see the oil loss because it’s going through the throttle body via air intake and then into the intake manifold and then into the combustion chamber.The catch can collects the oil and it eventually needs to be emptied.I have them on my 2017 Camaro SS and a 2019 Silverado Trail Boss and the 3 ounce canister is full at each oil change,which I change at 5000 miles always.The oil in regards to the AFM system suffers from 2 things eventually: The oil injectors that provide oil to cylinders that are idle (4 cyl mode) either over oil them causing piston ring corrosion or oil starving either the rings or lifters or both,all bad and can flatten the camshaft in seconds.All manufacturers are having similar issues from GDI engines.These engines are more powerful and fuel efficient but this is a side effect of oil consumption and corrosion.The catch can is the only way to maximize the engine’s life in this regard.AFM is a good system and most engines are fine with it but there is a possibility of these issues to arise so I pre-emptively took steps to prevent it.I use Walmart’s Supertech synthetic oil(it’s EXXON/Mobil oil) and WIX filters and no issues.I will say that Royal Purple with it’s array of additives can help an older engine although it’s about $37 per 5 quart jug but it is great oil.Try it once or twice and see.I am not a sales rep,just a long time car guy that has been around the block more than once.
By the way to the RAM buyer:The HEMI engines have more oil blow bye than any other engine,so much that JLT performance which normally uses a 3 oz canister for their catch cans upped their cans for HEMI engines to 6 oz canisters.The GM 3.6 VVT V6 as well as the FCI Pentastar 3.6 V6 are also on the list of the worst engines as far oil blow bye is concerned.I have a 2014 Impala with a 3.6 and it’s canister is full at every oil change also.So your RAM truck will eventually see the same results because it has DFM(AFM same thing).My brother in law just bought a new 2021 RAM 5.7 but drove a 2020 RAM with 18K miles on it,he asked why it came back with such low miles and they said it was a buy back.The oil blow bye at 18K had already carboned up the intake,a piece broke loose and flattened the camshaft in seconds.I saw this on a Silverado 6.2-same exact scenario at 140K miles.So he bought a catch can right away after buying his new RAM.Again all manufacturers have GDI engine issues so switching brands won’t fix it.
I have a 2014 Silverado and it burns a quart of oil every 1000 miles. I need to know more on how the lawsuit came out or if it’s still on going. Plus how to file a claim for my issue.
Thanks
Tara Crosby
It is too late sell now while used prices are artificially high
Mine is same as others. Need fixing asap. Thanks
Is the Law Suit in Ohio something new?
When is gm gonna fix the oil consumption in there trucks. Mine is a 2010 gmc sierra sle 4×4 truck with the 5.3l engine and it does the same as others. Thanks
Chevy should just go to electric……..this oil blow by is their way of condemning the gas engine to the junk pile! This is DELIBERATE! You know Chevy is part of the destruction of America!
I’m just curious about what they plan to achieve and what about your older 5.3 guys like me with the 2007 LC9 5.3 with the exact same issues, fouling plugs one time breaking the ceramic on them from oil build up. White smoke on hard acceleration, 1 quart every 5k miles.
This lawsuit was dismissed recently for the second time.
How do I enter into this lawsuit it is not only that year model I have 2008 Chevrolet Tahoe and it has all of the same issues the oil
Just disappears I have had to replace my engine and still the same. I live in Georgia but the money I have spent on oil and engines and trying to get it fixed I could have bought a new car by now. Also anyone I know driving a 2008 and up flex fuel has this problem
I to have been experiencing alot of these problems with my 2012 Chevy Silverado 5.3L. just in the last month, I’ve dealt with, well first a collapsed lifter on cylinder 1, which then started a misfire on cyl 1. Since i had just done all the lifters w/trays and gaskets and vlom and spark plugs not even a year ago. So i was able to warranty out the parts. Fixed lifter, and replaced the fouled up oily sparkplug from cyl 1, with no luck. Still had misfire. I replaced so many parts and sensors and today, as i stayed tearing it down to now do the cam, i see oil down in the combustion chamber. I am at my witts end. It is possible to get involved with this lawsuit?
I have a dead cylinder in my 2013 GMC Yukon XL As I f the is contact.
I’m trying to understand why the 4.8 is not an issue. The only difference in the motor is the crank, giving it more stroke, which increases the displacement. Even the piston rings are the same part number. I see many abused fleet savana’s with over 300,000km still running strong. What am I missing here?! I think its the 4 cylinder mode/fuel saving mode. Without fuel spraying into the cylinder you really aren’t lubricating the rings.. causing excessive heat and wear. Thats my guess.
The 4.8 didn’t get AFM so it won’t suffer the occasional cylinder/lifter issues.I had one in a 2010 Silverado and it was awesome.
How do we join this lawsuit because I have a 2011 chevy Avalanche and have had to replace the oil pressure sending unit several times within the last 3 years because of its design. This truck has had several issues with oil regulation and its ridiculous.
How do I join the lawsuit.
This problem will fall on deaf ears just like the law suite about the cracks in the dashboard and all around the passenger side air bag GM does not care about its customers all they want is your money the there over priced product
Please contact me as. I have a 2011 Chevy Avalanche and it’s burning oil and smoking out the exhaust. I just had a mechanic check and this is the exact problem.
Where do we sign up on this class action? I have a 2013 Avalanche …
From what I understand the lawsuit was thrown out by a judge years ago. What I did for my 2013 suburban 130k mi. was install an oil catch can and a Range device in the OBD port to keep it from going into AFM mode. 8 cylinders all the time. Trying to prolong the life of the Burb. Now the oil consumption is minimized at the 3000 mi. oil change. Best of luck.
I am having several related issues on my 2012 Chevy Suburban. How do I file a claim?
Do not waste your time.
sell now and cut your losses courts have already said that gm engineers have “big guy” moments and these moments are not covered by any warranty.
Husband has cancer. We can ‘t buy another vehicle. We need this one for work and family, to work properly..,
Not an option. Not everyone has money floating around. I am a disabled Veteran.. Can’t afford to replace it now.
If you are burning oil your only option is replacing the motor, I would rebuild my own using an independent mechanic and machine shop and a AFM eliminator kit.
No cash ? shut off AFM and keep adding oil.
I have a 2014 GMC Sierra & I having similar if not exactly the same problems as listed in this lawsuit. Could you please add my name & truck make & model to your lawsuit, please & thank you.
I have a 2013 silverado that just started burning 1 quart every thousand miles the truck barley has 90k miles on it I’d would like more info on weather a class action would be a possibility.
I have a 2021 Suburban High Country 6.2 with 15000 miles and it burns a quart of oil per 4000 miles. My theory about this is that they drop the RPMS dn to 100 at idle and this causes low oil to cylinders and the oil burns dew to higher heat in cylinder and less oil. Absolutely no need to ask Chevrolet service about it because Chevrolet keeps them dumb down due to “proprietary” reasons…….just like the GMC Terrain 4 cylinder internal oil burn, the Arcadia 6 cylinder internal oil burn and the infamous 2017 5.4 Suburban blowing injectors by drowning them with oil. All part of that diabolical WOKE nut job who is RUNNING/RUINING GM. Her plan is to get us to HATE gas engines so bad we will ride electric bikes instead. It sounds far fetched but not in todays world where corporate America is nothing but an extension of our SICK government! I think I’m pretty BURNED OUT!
Ohio Judge threw out the case stating the engine defect did not cause the plaintiff harm. just stupid!!
i bought a used 2012 GMC Sierra with 67k miles on it, now im right at 100k miles, and i change my oil myself and noticed alot of oil missing during changes. It takes no time for an oil change because theres probably half in there. Im gonna be checking it more often now to make sure im not running it dry. Is there anyway to fix this yourself besides a rebuild? Im not that mechanically inclined so I have no clue what the afm is nor ever heard of it. Guess ill do some research. Has anyone found a way to enter the lawsuit?
The best thing you can do is buy a RangeTech it disables the 4 cyclinder mode. Switching back and forth from 4 and 8 cylinder mode was where I was losing most oil. I was burning almost a quart every thousand miles at 100K mileage. I’m only missing 1/2 quart now in 5,000 miles. I also put the updated valve cover on (improved baffle design supposed to stop oil from getting sucked into the intake). That may have helped some, but not much according to my records.
I see a lot of people complaining here, but are they also complaining to the right people. I have the oil issue plus my frame on my 2013 Silverado has holes in it. Not only holes both rear shocks broke free of the frame. I have a truck that is not even 10 years old that is basically a lump of trash. Until you complain to the NHTSA, BBB and maybe your Consumers affairs office in the State Attorney Generals office GM will not be compelled to do a damn thing. We need everyone who complained here to file a complaint with the state and federal authorities or nothing will ever be fixed by GM. The more everyone screams the more pressure will be put on GM.
You need The Range Technology AFM disabler (part# RA003R)and an oil catch can.The catch can keeps the oil from going back through the throttle body via pcv and corrosion of the intake manifold and combustion chamber ensues.All GDI engines suffer from blow bye,some more than others.I have used these add ons and the catch can reservoir(3oz) is always at least half full. I only lose .5mpg. About $235 fixes it.
So a catch can and the AFM disabler is all you need to bypass this flaw in the motor? Whats the down sides to this? Im not savvy on working on or doing anything inside the motor nor do i know what the disabler is and does. But will google/youtube accordingly.
The disabler plugs into the OBD port under the dash and simply stays in,very easy.The effect is keeping it all 8 cylinders full time,the AFM shuts down 4 cylinders at various rpm&gear intervals.The problem with this system is when the oil blow bye gets returned into the throttle body and enters the intake manifold causing corrosion and build up. There is a VLOM(valve lifter oil manifold) that squirts oil to the deactivated cylinders,if clogged it will starve the lifters and engine failure occurs,or if it oils too much it corrodes the piston rings causing oil consumption.Simply deactivating the VLOM solves the issues as best it can if it’s an engine with miles,if new it prevents those issues.The catch can installs simply by being between both ends of the pcv line,when the oil vapors are heavy enough they fall into the canister and keeps the air intake hose and throttle body clean without corrosion. Racers have used catch cans for decades.
2017 GMC Yukon xlt, burn oil and fouls out cylinder 6. Had all of the lifter replaced but we are still having an issue
Late to the party , but just found out about this. Bought a 2014 GMC Sierra 5.3 V8, SLT Z71 certified, from a GM dealer, end of last year . It had only 28.8K miles on it, previous owner only drove it in town and most on weekends, it looks new. Did my first oil change on August, while it was showing 25% of oil life and 33.5K. But the “Add Oil” warning came on. So stead of adding oil I changed it, it was toooo low, below the dipstick. Now with 35K oil is very low, showing 50% of life still. I was too exited to get the truck and I didn’t do my home work. I figured ; hey is GM is good. Its my second GM truck. My last one was a 2003, same engine size, but not this Eco $hit, I drove it to the ground with 175K miles, engine ran like new, never had to add oil between changes, the body felt a part completely. Now what? Not sure if this is covered under the extended warrantee that I purchased from the GM dealer, if the dealer sees it as a problem, you know how it goes. Any advice will be appreciated! Be save out there!
Certified by whom? Certified is a term that seems to be thrown around by dealers nowadays. I would think a 2014 is too old to be certified by GM. Contact your dealer and get it in for an appointment.
Good question! I forgot to mentioned, I bought extend warrantee, bumper to bumper, up to 60k or 48 months.
Sorry but you will have to suck it up and deal with it. I loved my Chevy Silverado, a 2013 whose frame completely rusted out and GM kept telling me that is was normal every time I brought it in. Not too mention the oil burning. My Chevy was a mess. Last one was too . I had a 2005 trailblazer that also ate oil. Also had electrical issues. GM doesn’t care. Once they get your money they are gone.
I’m having the same problem what do we do about this
Oh no
The oil is being sucked out the engine though the pvc hose running from the rear of drivers side cover, the hose then into the intake above the the number 4 spark plug. Someone told me on this web site. The fix is to install a JLT catch can into this hose. I got my that Summit Racing $150 bucks. Been on 15,000 miles . It works almost 0 oil burn
The one you installed is the same for all years, being that the vehicle have same engine? 5.3 V8?
By the way, thanks for the info!
Years are different my 2013
We have a 2014 Silverado with 5.3 liter engine and it burns 2 qrt oil i less then 5000 miles. We use full synthetic and only have 68000 miles.
We bought the truck from a chevy dealer with about 54000 miles on it. Seems like they should have known about the problems with these trucks. Would the hold any liability for this current issue?
The oil isn’t “burned”,it gets sent from the pcv back jnto the intake manifold via the throttle body which is why you see oil residue in the air intake hose and on the throttle plate.The remedy is an oil catch can and also a Range Technology AFM disabler(optional-keeps the engine in 8 cylinder mode full time ). My catch can is full at each oil change ,this saves the intake from corrosion and engine damage. Oil ultimately gets into the combustion chamber where only fuel,air and spark belong and corrodes the valves.
