The 2021 Chevy Silverado 1500 and closely related 2021 GMC Sierra 1500 are among the least reliable vehicles available today, according to Consumer Reports.
CR recently published its 10 Least Reliable Cars list, which uses data from vehicles from the previous two model years to try and predict the future reliability of vehicles from the upcoming model year. Based on its findings, the 2021 Chevy Silverado and 2021 GMC Sierra are projected to be the least reliable vehicles, receiving a Predicted Reliability Score of just 13 out of 100.
A handful of identified problem areas with the 2019 and 2020 model-year Chevy Silverado and GMC Sierra contributed to the low Predicted Reliability Score for the 2021 model-year versions of the pickups. CR’s research found persistent issues with the trucks’ brakes and in-car electronics, along with some smaller and/or less persistent issues with the transmission and power equipment/accessories.
CR says it studies data taken from 329,000 vehicles from the previous two model years when trying to identify the most and least reliable vehicles for its annual ranking. These vehicles are also ranked across 17 potential problem areas, ranging from major components like the engine, transmission and four-wheel-drive system, to less crucial parts like the in-car electronics and body hardware. That means that anything from serious engine trouble to trim pieces falling off can have a negative impact on a vehicle’s Predicted Reliability Score.
The second and third least reliable vehicles for 2021, according to CR, are the Subaru Ascent and Volkswagen Atlas three-row crossovers, which received Predicted Reliability Scores of 18 and 19 out of 100, respectively.
The Chevy Silverado 1500 and GMC Sierra 1500 were the only full-size pickup trucks to appear on CR’s 10 Least Reliable Vehicles list. They weren’t the only pickups period, however, as the Chevy Colorado and GMC Canyon also make an appearance in this unfortunate ranking.
“One of the main reasons people buy a brand-new car is the promise of a no-hassle ownership experience, free from the drip, drip, drip of service problems that set in as cars age,” CR concludes. “Nonetheless, CR’s exclusive Auto Surveys tell us that some buyers will be taking their brand-new car back to the dealer’s service department sooner and more often than other car buyers will.”
GM has already issued a number of recalls for the 2019 and 2020 model-year Chevy Silverado and GMC Sierra 1500 so far, including one over braking issues on the trucks.

Not surprised. This thing has been recalled every month since it came out
How is this possible? They trash Yukon, Tahoe and Suburban while praise Buick which shares the same platform with former ones and 80+ percent of its components?
The old adage applies: don’t buy a new/substantially revised model in its first year of production. Wait for the bugs to be worked out…it applies to hardware as well as software.
I have been a GM owner since I was old enough to drive. I am 46 years old.. We do have some reliable vehicles, 1990 GMC pickup, 2003 Impala. We have had “problems” with our 2012 Acadia. Mostly electrical. I wish GM would concentrate on reliability not initial quality. I’ve got my hands full trying to convince my family to stay GM.
Tech has changed quite a bit since 2012. I have 2018 Colorado and is had been very reliable. You may have gotten a lemon.
Dan ,I too have a Colorado LT crew cab long bed , I bought mine in 2015 the latest model and it been great reliable truck ! I just take it in for regular service, oil and filter change and to rotate tires .
My 2018 Colorado LT 3.6 is excellent, drives great good gas mileage and performance and no issues what so ever.
So would you buy a new 2021 Sierra 1500 now or wait another year? It’s interesting because I wanted the new 2021 but after reading this article I guess I should wait. Another question is how do you find the right sales person at your local dealership?
Thanks
Wait for the 2022 redesign. I’ll be doing that
They’re not redesigning these trucks until 2025.
So they ruined the looks and the reliability. That’s why after driving Chevy trucks most of my life, I won’t buy one.
I switched to Ram in 2017. I’ve been waiting for the 2022 or 2023 refresh of the Silverado or GMC to purchase one but as I read about all the issues, I’m not sure I will buy one.
I bought a new 2020 Silverado Custom 4X4 quad cab in January of this year.. absolutely awesome truck..no problems with it at all. Brakes, engine (5.3), transmission all in excellent working order. No rattles, abnormal noises and it is tight and quiet. I traded a 2017 F-150 for it..the Ford had rattles, an issue with surging and the brakes were mush. CR has always been biased against GM. I’ll stick with GM as I’m completely satisfied with my Silverado.
Have had mine for 8 months. Some glitches with Sirius radio which have been fixed with a recent ‘over the air’ software update. Love my 2020 Trail Boss LT!
You wisely got the 5.3 with the old 6 speed instead of the trouble prone 8spd
It’s a 10 speed and mine has been flawless so far. Actually, my last 2 cars were both from GM after 20 years of BMW and Porsche and I have to say that I don’t see any difference in dependability. That being said , I do a 36 month lease for the term of the warranty
Th Custom with 5.3 V8 only comes with a 6 spd auto.
I also went Ram in 2017 even though I work for GM. In 4 years it has been absolutely trouble free. I still have my 2012 Cadillac and 1987 Grand National but GM has me very leery of their pickups. I have grown to love the Hemi and ZF 8 speed combo.
I am a die Hard Chevy fan but my2017 and all others have 8 speed trany. are junk. I will not buy another, I think the trany must have been built in CHINA.
In reality, the much maligned GM 8-speed was conceived, designed, engineered and is built in the USA.
GM was too cheap to source a decent transmission from a supplier and they messed up in building their own.
The Apple iPhone is built in China and it has the highest customer satisfaction rating of any product in history. So much for your theory.
The ZF 8 speed in my Hemi Ram is just awesome. GM should have just gone with that transmission as so many other manufacturers have. How is it that GM was able to make so many awesome automatic transmissions going back to the 1940’s but struggles so much now?
I agree @Edward M Pate. I believe that GM should’ve done whatever it needed to do to have all of their truck transmissions supplied by Allison. Allison is the best transmission in the world in my opinion!
It wasn’t the transmission but a bad fluid spec. They have it fixed now. I have an 8 speed ZR2.
Chuck. The problem has been identified and resolved on the 8 speed. The trouble was the fluid it used.
GM worked with Mobil1 for a new synthetic fluid that resolves al, the issues. Dealers have been for almost 2 years flushing them under warranty to correct the issue.
A number of transmissions have been suffering shudder issues do to moisture being absorbed into the fluid. It was far from a GM only issue.
Quality requires being built right initially and not identifying the problem and fixing after the customer is …sed off!
Only time will tell if the fluid change solves the problem. Will this transmission last 150,000 miles? That’s the big question.
I’ve never had a gm transmission last that long.
My 6spd w 4.8l engine is at 180. No problems.
I’ve had the latest and greatest fluid change, no difference.
My 2017 Silverado still has the occasional shudder and shift klunk prevalent at low speed shifts. Not a fan of that 8 speed at all. Been in 3 times with the latest visit supposedly a reprogramming flash that was supposed to be the big fix….wasn’t. It’s improved a bit but still there. Coming up on a trade cycle, likely for a 22 model but will watch carefully for improvements and see how the 10 speed is any better.
Get the flush!
It should be under the driveline warranty.
The greatest trouble with the transmission is not so much the shudder but the dealers that either don’t know what to do or refuse.. This is why GM need less dealer.
C8.R,
Be careful what you wish for.
I once had a lawyer working for me who always said, give them enough rope and eventually they will hang themselves !
When GM has no dealers to blame who will you – they blame then ?
GM is going to spend 27 Billion on EVs and can not fix this GM 8 speed junk transmission !
This is a problem for GM VS Tesla !
You see the owner and the stock price is not linked to the vehicle , its linked to the company and its values !
GM gives money to this and that trying to seem like they care about things other than the shareholder !
Yet can’t take care of the very customer buying their product !
C8.R,
Once again you are a liar and full of $hit !!
C8.R , had his whole entire GM 8 speed junk transmission replaced !
I wonder why ?
If GM could change the fluid ?
He knows why !!!
Yet still just comments and lies as its just a simple fix guys !
It is a simple flush for some.
However there are MORE the fix does not work for than it does work for.
And after years of this GM 8 speed junk, most have it, have sold it and passed the junk down to the next dissatisfied GM customer !!
Again, I am NOT saying ALL the GM 8 speed junk transmissions are bad !!!!!!
But when you get a bad one, and it is a HIGHER rate than you are being told, it is just that A BAD ONE !
GM might flush it, if the dealer is GREAT !
GM might replace the torque converter, if the dealer is GREAT !
A tune might fix it !
But when they are loaded up with burnt $hit from the torque converter clutch, they are $hit !
The best thing ANY REAL GM loyalist like myself could tell you is ,
DO NOT BUY A GM 8 speed junk transmission vehicle !
GM has HORRIBLE, HORRIBLE, customer support !!!!
Let’s clarify this for once and for all.
Yes my transmission was replaced under warranty as I felt it did not engage soon as it should. The dealer replaced it with a new one ASAP and no hassle. Note since then it has been sent out in a TSB that the delay after sitting for. Days is normal. To be honest it is the same length of time as the old Chrysler transmissions were.
Next the vast majority of transmissions flushed were corrected. Just visit the web site for the Colorado and Canyon that address the issue. The few not corrected had glazed clutches as they went too long before th3 flush. GM is fixing those with the drive line warranty and replacing the converters.
All this can be confirmed by the many threads on the forum site too.
No a tune will not fix this as it was never a tune issue.
The facts are what they are and lies from some will not change thing to the delusional comments some post and could never back up.
I am not sure what some want. The fluid and or the converter fixes the issue. We have seen high mile drivers on the forum with nary another issue.
I suppose if GM took the engineers out and shot them then fed them through a paper shredder only then would they be happy.
Please visit the forum as there are many happy owners there. Also Google transmission shudder and count the brands with the same thing.
My truck runs great GM took care of the issues and I had great service. I could not be happier with my truck.
YES C8.R you have explained this before to me and this site.
So lets clarify this once and for all, like you said !
IF EVERY GM 8 SPEED JUNK TRANSMISSION OWNER WAS TREATED LIKE YOU ALL WOULD BE GREAT !
Again what can you not get here ?
There are thousands of GM 8 speed junk transmission owners in ALOT of GM vehicles that ARE NOT getting your royal treatment !
I have Googled the trouble for years !
I have followed the forum for years !
Have you Googled the rear differential issues in the 2007 Silverado HD ?
There are not any issues and nobody is raising concern ( complaining to you ) !
I have a 6 speed in my Canyon with a Trifecta tune and love the truck !
I have a 10 speed in my 2020 HD and love the truck !
I will NEVER and have NEVER owned a GM 8 speed junk transmission !
AGAIN why ?
Just like you said, Google it !!!
Read the forums !
Nobody is asking anyone to shoot the engineering team that was in charge of this piece of $hit GM 8 speed junk transmission !!
ALL ANYONE WANTS IS EXACTLY WHAT YOU GOT !!!!
THE GM 8 SPEED JUNK TRANSMISSION FIXED !!!
In your own words ! The dealer replaced it with a new one ASAP and no hassle !!
And one more thing, for some reason, all of the commenters here and on all of the forums are trolls to you and some of the other common commenters here, how ?
There are thousands of these GM 8 speed junk transmissions out !
Why is this ” Fake News ” to some ?
Its like politics. WE ARE ON THE SAME SIDE !! WE ARE AMERICANS, WE ARE GM LOVERS !!
You got great treatment, others including myself DID NOT !! It does NOT make us liars !
Just like politics and the stock market or the state of economics in our country.
WE ARE ON THE SAME SIDE, and are losing to other countries because we can not even agree on one simple FACT !!
Like the ONE SIMPLE FACT that GM mad a horrible 8 speed transmission here, has horrible customer support in trying to fix it !!
Like I said, there is NO ONE saying ANYTHING on how horrible the rear end is or was in the 2007 Silverado HD
My 2017 Colorado did have a few issues, but over the 3 years and 50,000 miles I drove it, reliability was actually quite good.
It’s replacement, my 2019 Silverado, does have a minor issue with Bluetooth connectivity, but otherwise has been flawless over its 12,000 miles.
Steve, Calgary, AB
Yup electrical issues seem to be a big problem. If they don’t get better quality control can you imagine what the EV’s will be like.
I’m 68 yrs old….our whole family over the years has bought only GM vehicles…my 17 GMC Sierra 8spd is a real disappointment….my wife’s 16 Cadillac is one of the most trouble free cars I have ever bought…..Dont know if I will ever buy GM new again….
Not hard to figure out why FCA has been eating GM’s lunch…
Yep, large discounts
Just a better value product and far more reliable.
Why would I lie?You Sir are a liar to a degree.It worked great for me,I also went into the dealership EDUCATED from reading the Camaro6 forum and found the TSB on it.Otherwise they might have tried to pass it off but since I dropped the proof in their lap they had no choice.It’s been 20K miles since and not a single issue.Stick it up your a*s dude.
FCA is giving away its product with the deepest discounts. That’s not a sustainable business model.
So The only lunch FCA has been eating is its own… and even then it’s a half-baked one.
It is also part of the reason GM stock is over twice the value of FCA as they look to merge with another company for survival.
Bill, it’s a slight of hand. The false impression is that the *new* Ram Ram is outselling the *new* Chevy Silverado, leading people to wrongly deduce the Ram is better than the Silverado. Ram has been selling the new Ram and the heavily-discounted old Ram at the same time. FCA conveniently doesn’t break the sales numbers apart. It would be interesting to see how ONLY the new Ram Ram is doing versus Chevy’s Silverado… I suspect the numbers would be the same as they’ve historically been… FCA trailing in third.
Bill, don’t let the GM kool-aid drinkers here fool anyone !
I am NOT a RAM lover, and have NEVER and will NEVER own one !
However the current one is a better truck than the GM, in and out and in the drivetrain, and GM knows it !!
GM has been scrambling to get their truck changed and updated for 2022 !
And as far as discounts, GM had $9,000.00 to $12,000.00 on the hood of their trucks when needed alsoto get them to move.
And as far as the stock price people here.
Does that mean that Tesla is 13 times better than GM then ?
You are saying that GM is better than Ford and RAM do to their higher stock price.
Just a bunch of school kids, only compete with the lower class when you cant compete with the upper ones !
Its like the Cadillac people always saying, Well Cadillac outsells Lincoln !
Look at me, I have more than the homeless , I am a winner !!!!
Its a sad day for reality and facts !
Wow a lot of first time posters here with a similar script?
Number 1 this is Consumer Reports. Their findings are based on a random group of subscribers that is seldom accurate or consistent. You can find similar models year to year being on and off the list yearly.
You also find similar models with different grills being on and off the list at the same time even built by the same people and same parts.
The truth is none of the big three trucks are perfect. But as a whole GM trucks are not the worst of the group. Ram for years has had issues as have the Fords too.
In fact the CEO of Ford wants to cut down warranty claims as it has cost Ford $2 billion dollars more a year than GM in cost. Much of that is due to trucks their strongest sellers.
I have had my truck for 3 years and had one issue that was taken care of with no hassle.
I would not trade my truck for any of the others as I really enjoy it.
Again C8.R,
SURE, SURE you really enjoy your truck !
The GM dealer you work with on a daily basis caters to you as you do to them !
This is the definition of corruption !
I do a favor for you – you do a favor for me ! And we will tell others its great !
Again EVERY GM 8 speed owner would also ” REALLY ENJOY THEIR VEHICLES ” if they too got their ENTIRE GM 8 speed junk transmission replaced !!!!
JUST LIE AND LIE AND LIE !!!
When will it end the corruption and lying ?
Do you need another ban aide?
Do you need some boner pills ?
Or should I say does your wife need some ?
You really don’t learn do you?
Learn what ?
How big of a dip $hit are you any way ?
Have a 2020 Trail Boss that has had ZERO issues. Same with my 2018 LTZ 6.2L.
The brake issues were a simple software flash. Nothing wrong with the hardware at all!
I strongly believe that the brake issue has to do with the fact, that rear 💽 brakes are not as reliable as drum. And will require constant maintainence to keep then work. Were as your drum brakes can handle the abuse of mud, snow salt rocks getting kicked up etc . But the brake surfaces are protected by the drum. This change is a money grab for the big three! But they have over looked the facts, we are not going to continue to buy garbage, that us consumers should have the right to choose our chose of brake systems, and your not going to get us to pay your shop rates for brake work, that we all know are not covered by warranty! GM engineers must get with the reality program. Not all of just buy truck to look good in the driveway!
Seat belt fraying, vacuum pump twice, rear power sliding window catch fire, and there is another one coming in the mail soon i hear.
That’s all well and good, but Ford is getting a major pass. Have you driven the new Expedition and Explorer? Or even the F-150? They’re all rattle-traps with atrocious build quality. Test drove a brand-new Expedition Max and the door trim was falling off, the stitching for the seats had issues, the ceiling trim was loose and rattling, there were some loose center stack knobs, etc…. And this is what the dealer is trying to convince me to buy? At $75,000? Hard no.
The Explorer I test drove was marginally better.
I’d rather have a vehicle that has had a few recalls to fix the problems under warranty or extended coverage than something that is literally going to shake itself apart for items that will not be getting any special recalls or coverages.
The general public is more concerned with electronic gizmos, “infotainment” (I hate that lame word must come from the progressive vocabulary) and gadget tailgates. None of that junk makes it a better truck. I buy a truck for capability, reliability, and ease of maintenance. GM doesn’t make a truck for me anymore, hasnt since the ‘88-‘99 series. I like the looks of them, but the price and reliability keep me away. My 4Runner does the daily driving and off reading, the 84 c30 does the work.
I have a 2001 Silverado pretty well loaded I purchased new and still have it with 237K miles on it and almost zero issues. Had to replace the heater switch. Almost ask for my money back. I also have a 2017 GMC Sierra SLT crew cab with every option and 33K miles with no issues. I must be doing something wrong.
consumer reports is biased anti-American= anything made in America from a sledge hammer to automobiles will bring out their bias.. case in point– Toyota and GM joint operation produced the corolla and a GM marketed Prism at a California assembly plant, using identical engines, trans,everything, the only difference was sheet metal,, grill, tail lights etc, etc . consumer reports rated the corolla a best buy and the Prism do not buy.. they are the bernie sanders of print magazine
,
I would say more Ralph Nader based on history, but point taken.
Had a 19 RST for 1 year and 5k miles. First day cab leaked and ruined the headliner and carpet. Have to pull the front window to replace the headliner. Next issue was the transfer case making noise but only in 2wd. This truck was never off road. They tried to fix it but it came right back. So anyone who has an SU4 model transfer case be wary of this issue. Just traded for a Ram Limited. Lifetime Chevy man has turned his back on GM.
I have the 2019 Silverado 1500 LD. It’s the old K2 platform. Don’t have enough miles on it to comment. I hope this Legacy model had all the bugs worked out of it.
I do not like taking any of my vehicles to have service. I do all I can at home, I have a hoist. So when I hear the issues it makes me cringe.
They do! have an 18 no recalls only one service visit for a dash rattle,most of the bugs (A/C condenser,roof mount antenna leak etc.) have been updated. Going to install LS9 valve covers and a catch can,clean intake valves and shut-off AFM when the warranty expires and hope for the best. I have driven the new ones and see no advantages except for box volume, ride quality,performance etc.no difference, styling and interior, like previous gen better, plus to get the same options you need to buy packages and cannot get fog lights at any price(non Z71 LT). I would run away from any 8 speed trans. $20 a quart fluid or not
OMG. Talk about another slap in the face to GM.
Garbage, period.I love my 2019 Custom Trail Boss Z71.Not one issue,I went through 2 software recalls but all manufacturers are guilty of that nowadays.Consumer Reports is a garbage magazine.
The times I’ve listened to CR are the times I’ve been badly stung. Now I see what they DON’T recommend and buy that. Haven’t gone wrong since.
In no fashion would I ever believe CR results when it comes to reliability issues and I’m a subscriber to CR digital. Don’t think GM is the only one out there hanging themselves. Please read this Ford Authority article. Ford warranty is cost them $1-$2 billion year.
https://fordauthority.com/2020/10/ford-needs-to-focus-on-curbing-warranty-costs-ceo-jim-farley-says/
Ooh look, another dig from Sam!
I have a 2013 bought New single cab work truck. I have to roll my own Windows up clean the dew off the window no carpet. It just kills me the Power tailgate. My truck has 190 thousand trouble free miles. And for anyone that has bought dodge I feel bad for you wait. to hit the high mileage if you keep it that long.
This is my 13th Chevy truck,never had issues of note.With the GDI engines just make sure you get an oil catch can and all will be well.It simply catches oil vapor that would have gone through the throttle body and intake manifold and then the combustion chamber.Oil is not supposed to be in the combustion chamber,it causes carbon build up.Easy fix and ALL manufacturers are seeing the carbon build up so GM is no exception.Software recalls are a normal thing now.Tech: over hyped and rarely deliver what is advertised.Apple is a garbage company as well.
how true Stan, I remember CR denigrating the GM 3800 V6 as sluggish with poor fuel economy, although it would smoke the tires and get 32 mpg in a full sized sedan
CR top rated my CR-V, it got a trans at 120 k, Acura RDX , again to rated, excessive oil consumption and motor trashed at 130 k. 17 Rav 4 torque converter shudders ar 119k. 09 Gmc Sierra 160 k, still strong.
The comments about CR on this post are ridiculous.
2020 Silverado LT owner here. When I first did my research on the truck I was disappointed with all the recalls it had early on in the year, so I waited. I made sure to check the VIN number when I bought the vehicle which showed no recalls. It looks like all the problems happened early in the year for vehicles manufactured in the first quarter. Got about 5k mi in so far without any issues and I love this truck. Hopefully it stays that way. I took the lease so if there is any reliability issues I can just turn it in. I honestly don’t know where CR finds these people cause every Chevy owner I know absolutely loves their truck.
CR doesnt find these people. These people find CR, and by the way, it’s called statistics – besides which your friend’s experiences mean nothing.
Well, my first-ever brand new vehicle, a ’19 Sierra with a 6.2.
I did the first oil change at 1000 miles and every 5000 after. At 20,000 mile oil change it was a quart low. At 25,000 change it wasn’t even showing on the dipstick.
After many years of having to watch over my vehicles closely because I couldn’t afford new and couldn’t pay someone else to fix it, I didn’t think I should have to check my oil every time I drove it.
GM told me to drive it until it broke and they would address it then. I took that as “we will find a way to blame you when you end up sitting in the middle of nowhere with a blown up engine and not honor the warranty”.
Mike…I have a 17 GMC SIERRA DENALI …68000 miles…it burns a quart in between oil changes since I’ve had it…I change every 7500 miles with Mobil1
I specifically insisted on full-syn from day 1. I have built race engines for over 30 years, alcohol, gas, 2 stroke and 4 stroke.
I totally understand using a catch can I a high-perf, high compression engine being revved to the moon. I don’t agree with needing a catch can in a street engine that should be expected to last 200k miles.
I bought a Ram. Especially since the value of my used Sierra had gone up a bunch the last 8 months
The problem with direct injection is that raw oil vapors are causing carbon build up, some oem’s are now going back to using port injectors to dilute the oil vapors in addition to direct injectors. I feel a quality catch can in addition to spraying in a can of DI cleaner every 10 k miles should keep the valves clean someday I will pull the intake for a look-see. also going to look into the cost of LT9 valve covers rumored to be a better design.
Mike read my post on oil catch can…. absolutely imperative to get one.$149@JLT performance bro,worth every penny and a 10 minute install.Empty the 3oz canister at each oil change.You will be amazed.
Also Mike use full synthetic oil,not the semi synthetic oil that the dealerships use. I also use the WIX filters,good deals on Amazon for them.
CR is fake news . I have 2 of these vehicles haven’t has a seconds trouble and have enjoyed blowing Dodges, Fords and Toyotas off the road. These trucks will fly with 6.2s in them
As if your experience with your two trucks negates the 1,000s of reviews from other Chevy owners.
I lost all respect for CR when they had the Ford Escape as one of the most reliable SUV’s and the Mazda Tribute as one of the lease reliable SUV’s back in the day. They didn’t even bother to research that the two vehicles were identical except for a few little things and the basic front end look.
I also own a 2017 Camaro SS and it has the 8 speed.They flushed it once after a mild shudder and it didn’t work.3 months later they brought it back in and flushed it,ran compressed air through it for 2 hours,refilled with the new Mobil 1 fluid.Then a reprogram of the transmission and it’s way better than original.I also installed the oil catch can and it saves these engines guys,no joke.For people seeing a quart low at each oil change,if you were to see inside the throttle body and intake manifold you would find your missing quart of oil.
Lifelonggmowner has some real issues folks.Peddle your conspiracy theories on a Trump propaganda site or in the trash where they belong.My transmission was not replaced,I was there and it didn’t happen.Stop lieing and accusing people of things you know nothing of.Also by your posts I can tell you don’t know much about anything really.
Thanks Joshus Coker
I was talking scott3 AKA C8.R and his entire transmission WAS replaced and HE was their !!!
As for you, and the other GM kool-aid drinkers here !
If you love your GM 8 speed junk transmission GREAT !!!
!!!!!!! JUST GREAT !!!!!
did I say one thing bad about anyone here who has had GREAT luck with their GM 8 speed junk transmission ? NO the answer is NO !
Talk about GM fake news propaganda !
And again, I have never voted for the loser Trump !
I am so, so, sorry for you Joshus Coker, I did not realize you had so many deep issues, I have heard you can get help for that !
I find it best to Lease any brand car or truck so my maintenance is nil and after the 36k I turn in and lease again. No way do I want to Own any issues and pay new car depreciation
With pumped up residuals and incentives on interest rates and waiving fees and payments Leasing is the way to go. My GMC Canyon has a 70% residual over 24 months. Best GM has to offer and a 2% apr and employee pricing in August made a crew cab 4×4 Denali under $400 a month after tax and no cash down
My 18 GMC Canyon lease turn in was worth more than the dealer buyout
Really no other way to go the Manufacturers make it that way so who cares if they’res any issues I don’t own it
I have a 2016 Canyon and 2018 ZR2. Besides a few minor issues both have been very reliable vehicles. People like to complain and will cry no matter how good their vehicle is.
Why are you lying? I mean don’t we have enough of that going on in the world today? I work for the 2nd largest construction company in the US and our Fords on the site are only as bad as the Dodge you really need to get out and actually test vehicles my guy
37,000 on my ‘19 Silverado. No problems yet. Had a couple recalls on minor things. So far so good
CR isn’t a reliable source. It’s only based on owner filed complaints. A car can be trash, but if it’s owned by people who don’t know anything about cars, (Tesla’s anyone? Nissan sidekick?) most people who own these can’t change their own tire. Honestly, a low CR score is honestly a good sign that a car is competitive in its class as it’s attracting discerning buyers, not just fanboys.
I take CR in a mixed way I feel owners that have minor issues may mark them as major or if they may report more problems than they actually had and then you might get some brand haters reporting on something they do not own.
It’s not based on owner filed complaints. It’s based on owner surveys – and there’s no reason at all that Toyota or Honda owners should know more or less about their cars than GM or Ford owners.
Try again….
Wow guy you have issues.I don’t have issues so f off.Stick to what you know like being a total moron.
The only constant measure here is: the more gadgets and electronics the new vehicles have, the more prone to problems, since now almost everything is electronically or electromechanically driven.
So when you sticj to a good old 6 speed and 5.3L engine in a moderate loaded Silverado you will be happy for life.
The 8 speed was designed, supposedly, to improve MPG, but frankly the only thing that improves your MPG is your MPH. 6 speed vs 8 peed could bareley make a difference after many miles driven.
For the last 17 years i have managed a 23 vehicle delivery fleet for the company i work for. Three of the 23 vehicles are a 14 15 and 16 Silverado. I have had more recalls on the 3 Silverado’s than all my other fleet vehicles combined over the entire 17 years. Just facts here, as i still love my GMs.
There you go C8R,I believe you.That other clown is apparently trying to spread misinformation.My Camaro SS was used as a guinea pig,while they were performing the fix they were in constant contact with Detroit as to the progress and the exact how to.The tech spoke with me afterwards and said as much.The reprogram isn’t a fix but it shifts way more aggressive and I love that.Thanks to GM for caring about my car.I am a lifelong GM owner and no interest at buying anything else.
I’ve owned a Silverado LTZ double cab for 6 years and never once have I needed warrantee or post warrantee non-scheduled service. I canceled my CR subscription last year because I couldn’t believe what they were saying about the Silverado. If GM reintroduces a double cab with Navigation, I’ll be at the dealer in a heartbeat. (I have no use for cell phone apps)
108k on my 97 buick. 133k on my 97 Blazer. No problems!! Maintenance people!!! Drop all fluids once…dare you. Both diffs, transfer case, flush radiator… c’mon now!
I have 2016 sierra slt and it is definitely a lemon. About 25k injectors replaced. Ist one side then other , but with the wrong ones. Then that was fixed. Check engine light kept coming on and they replaced sensors multiple times. Not including the worst shifting transmission ever. Last month the tr hardness was replaced . My gmc warranty ran out but they covered it. 200 miles later now it wont shift out second. I tried to love this truck but even with the extended warranty its in shop just about everymonth. Gm should be embarrassed the way these transmissions work. I only have 62000 miles mostly highway and baby this truck. 4 years old today and what garbage.
You guys are making me nervous. I was just about to pull the trigger on a 2021 Sierra 1500 AT4 Duramax Carbonpro, but now I’m having second thoughts.
Speaking of transmissions, I’m looking at doing this because my 2017 GMC Acadia Denali with 34000 miles is currently on transmission #4. (6T70) It’s great otherwise, good on gas, etc.
I know 2021 is the last year before a big Sierra/Silverado refresh, but frankly, I’ve had some bad luck with first year vehicles like this Acadia, the 2015 Sierra Denali before it (First year for the 8 speed) and my current 2020 Cadillac CT5-V which is currently sitting in my garage with “money light” #3 in only 2300 miles.
One last thought. I used to teach in a trade school there my students would frequently get into the Ford vs GM vs Ram argument, and I’d always tell them “They all make winners, and they all make stinkers. INCLUDING Toyota”
It is just a sheet metal and interior refresh so new “issues” like with MY 14 and 19 redesigns should not crop up and problems with the GM/ford 10 speed seems to be a ford electronic programming issue the mechanical parts/design are the same but the programming is separate but you never know about new designs including the new duramax till they get a lot of miles on many units.With all the problems with the 8 speed it is a mystery to me why the 10 speed was not “fastracked”,so you are rolling the dice with the drivetrain but do you want to wait for a up-to-date interior that you deserve. I do not buy the GM bs they did not have the time to do up a competitive interior I feel they were being tight hoping GM loyalists would take what is given there are too many automotive critics out there and this thing called the internet DOH
Jetfixer 2 of my co-workers just bought a 2021 Silverado RST Duramax 3.0L 4X4 and a 2021 Sierra equivalent and they are extatic about them.They love the mog and the quietness of the 3.0 and the 10 speed is silky smooth.The 10 speed is a GM/Ford joint venture and Ford is having fluid issues but I haven’t heard it from the GM side, probably due to the data from the 8 speed fluid issues.The infotainment system issues seem to happen with the updates to the brake recalls which were never an issue for my truck but if you don’t get them done the insurance company won’t cover you in an accident and you can be sued so it forces us to do it.The brakes on my truck(2019 Custom Trail Boss) never had the advertised issue but whatever.Buy the truck, they’re awesome.CR is garbage.
I have a 2016 GMC Denali 4×4 6.6L Diesel, no major problems love this truck.
I’ve owned GM trucks since 1986. The only one I had an issue with was my 2014 transmission. Recently had a 2019 AT4 put on over 100,000 km no issues. Just purchased a 2021 AT4 6.2. GMC finally started building decent trucks again.
My stance on CR results as far as vehicle reports rely mostly on its own consumers and recall notices. therefore, everyone has a different opinion of what is a problem. Recalls only report a perceived safety issues or known safety failures. Recently, GM issued a recall for “42” trucks, and not one more of the 500,000 manufactured.
On the other hand CR tests retail purchased appliances and do there own research plus a little input from it consumer base. That I’ll take more into my decision. A year and a half ago I purchased an LG washer and dryer rated number 1. They are working and clean clothes as CR tests results were.
I haven’t bought a new vehicle in a while, but have always been a Chevrolet fan. The only Chevrolet I have now is a 2003 Z71 Suburban with 198,000 on the clock. I wouldn’t trade or sell it for anything. That said I have had my share of really irritating problems with it over the years, from brake issues, to constant climate control issues to just really cheesy fit and finish. The biggest reason I would never get rid of it is I have had no issues with the power train/4WD system. It’s a 5.3 Vortec with a 4L60E transmission and because its a L59 motor I can run 85% Ethanol if I ever wanted or needed to. I am a firm believer that the more they try and “upgrade” the more they screw things up by they I am mean every auto maker. As far as work trucks go my first and only choice is Ford and always will be, I have a 1997 E350 with 400,000 on the original power train still on the road still making money!!
Add a 2019 LT, V8 with the 8speed transmission. I put 72000 miles on in the 1st year with not a single issue. Loved the truck. When I found out they put the 3.0 duramax with a 10 speed Allison in the 2020 RST, I traded my truck in the next week. Nothing wrong with the 19 but this duramax is a beast. Smoothest transmission I’ve been in other than the tesla. I currently have 31000 miles on the 2020 duramax and couldn’t be happier.
Keep up on your maintenance and you shouldn’t have a problem.
This is the problem” when someone says maintenance maintenance maintenance you wont have any issues” you buy a new vehicle to not have to wory about it breaking down or recalls out side of normal maintenance like an oil change. We shouldn’t have to worry about reliability period! At least under 100.000mi
Well I listened to everyone’s comments, thought it over, and then went ahead and ordered a 2021 Sierra 1500 AT4 Duramax CarbonPro. A few of my thoughts:
*I have the 10 speed auto in my CT5-V Cadillac AWD and, so far, I’m very impressed.
*I realize the ’22s will come with a redesign, but from everything I’ve read, its about appearance, but no real new tech.
*Push button shift? I’m “old school” and perfectly happy with the column shifter.
*Panoramic sunroof? I spend 95% of my time alone in the truck. I do like having a sunroof, but it doesn’t need to be larger.
*Bigger infotainment screen? When I’m focusing on the road, the size of that screen is unimportant. (To me)
*Outdated interior design? Yes, its very similar to the interior in my 2015 Sierra Denali, but I LIKED that interior so…
*Redesigned front end? The ’21 already has the improved headlights my 2015 DESPERATELY needed, so again, its fine.
So I’m a GM guy, and have been since my first used crappy Chevrolet Chevette in 1984 which I later traded in for a new 1985 Chevrolet Fiero GT right through to a few Tahoe’s and Silverado’s as well as my current 2019 Chevrolet Silverado RST with SCA Black Widow package, which by the way was the only thing that kept me from moving to a very appealing Ford Raptor. Also just added a brand new GMC Acadia Denali for my wife, so very much a GM guy. However, given the lack of upgraded and improved engines, interiors, technology and a modern panoramic moon roof is quickly getting me to consider my next truck, which will happen in 2024 (I only keep my trucks 4-5 years) will very likely be a Ram or a F150, especially given that they both have performance Rapotors and T-Rex with very appealing updated engines, interiors, technology and yes a modern panoramic moon roof. At this point GM has absolutely no competition for either the Raptor or T-Rex, and given this article, maybe they shouldn’t. What is next with GM? How can you possibly have poor reliability, you haven’t really changed anything in nearly 20 years, I mean these LS engines have been around nearly as long as I have with little more than this crappy DFM added, by the way, if there was a way I could remove my DFM and mail it back to you, I would. My biggest question for GM is how the hell can you possibly have reliability problems with your transmissions? The current 10-speed was developed in partnership with Ford, how could GM possibly F-this up? Not to mention the new 8 speed is a slightly modified version of the 10-speed, so what the hell is GM doing? Getting back on track, I was just looking at the 2021 Silverado’s and they are turning me more into a future Ford F150 or Dodge Ram guy. In 2021, how can every model from LT and above still have a mechanically adjustable passengers seat? What the hell? Is the GM design and engineering team left over from 1962? How in the hell can you offer mechanically adjusted passenger seats when you competition offers power adjustable for no to little cost? Next, and because I’m an open air guy, when in the next 50 years can we ever expect to see a modern panoramic moon roof in a GM product? I’m beginning to think we never will, again likely due to the fact that the design and engineering team are hold overs from 1962, or possibly 1902. Okay, so I lied, really my BIGGEST issue with GM is interiors, of which I guess a modern panoramic moon roof could be considered. Interiors, what can I say, these are worse than anything GM ever built in 1962. Being very serious, the interiors look like they were designed in a Lego studio, a LOT, and I mean A LOT!!! of hard dark plastics all over the place. Oh, and I would be remised if I didn’t ask what is up with all the fake wood grain plastics? Or worse yet, the UGLY bronze plastic bezel around the infotainment system on the upgraded interior, if that’s an upgrade, I’ll take the bland Lego studio stuff, as ugly as that is. Okay, so seats, where to start, oh, lets go again with the mechanical front passenger seat, same as the interiors….FIX IT!! Every time I have someone ride in my 2019 RST Silverado Black Widow, I’m so embarrassed to say I paid +75K for a really nice lift, wheels and exhaust, only to suffer from crappy hard plastic Lego interior and a terrible mechanical front passenger seat. The question I always get on that front passenger seat is “isn’t this 2020? how can you possibly have a mechanical seat”? Most of these folks then start picking on how crappy my 2019 interior is to their dated 2013, 14, 15…..F150 or Ram. How sad is it that a dated F150 or Ram interior can look better than a 2019 Silverado interior? SAD, VERY VERY SAD Team GM, just SAD. Oh, did I mention, the interior on the 2019, 20 and now 21 Silverado is SAD SAD SAD!!! Fix it GM, if you have any hope of getting back a +30 year GM guy. Okay, so now on to the other interior item, the infotainment center…..I mean what can I say…..SAD, just SAD. The infotainment in the 2019, 20 and now 21 is just a very minor upgrade to what I had in my 2014 Tahoe LTZ, the only add had been Android Auto and Apple Car Play. Overall, the infotainment in the 2019 – 21 Silverado is just a hot mess and really sad as compared to the competition. Next up, the engine offerings, so just how long have the 5.3 and 6.2L been around without change? My estimate is about 20 years, with little more change than the addition of this really dumb DFM system. Again, if there was any way in hell that I could pull off my DFM and send that crap back to GM, I would have done it one day after I had bought my Silverado. While my 2019 RST Black Widow came with the “updated”, whatever that means, feels beefier than the 5.3 that was in my 2014 LTZ Tahoe, the throttle is still tuned for my wifes driving, that is long lag in throttle response. Why GM should I ever have to buy a $300 Pedal Commander when you could simply tune the throttle to the guys who drive the Silverado? I guess your assumption is that the majority of Silverado buyers are +80 year old grandparents. Bottom line, the engines are archaic pushrod two vales with the only slightly modern add of variable valve timing. GM, look at the Ford 5.0L Coyote offered in the F150, or even the 3.5 Eco Tec Turbos, all modern dual overhead cam, multi valve with variable valve timing. The updated Ford 5.0L Coyote blows the sox off of the GM 5.2 and gives the 6.2 a run for the money despite giving up 1.2 liters to the 6.2. I don’t know GM, the more I write out of frustration that I love your product, the more I realize I can no longer support the crap product you are putting out. Sorry GM, but in 2024, I’ll take a Ford or Ram over a GM, I just can’t do it anymore, you’re not listening to what your customers want and need, and the product is failing as noted by the reliability trends which are supported by hard data.
Go ahead and buy the Junk 150 and Ram,we don’t care.I love my 2019 Silverado Custom Trail Boss and have 0 issues with it.I have the 5.3 with AFM and no issues, installed a CAI,muffler swap,Hypertech React and an oil catch can.All.of which are a staple of mine with any GDI engine I purchase in a vehicle.I love the functional interior and hate all the garbage tech that is NEVER reliable and NEVER lives up to the hype.You can take all the tech out and I would love it even more.Panoramic roof? Garbage.Go and buy the other junk out there,my friends have and I am the one they call for a tow.Also the pushrod engine is and always will be a superior engine to overhead cam design that cannot produce torque.Any overhead cam design does well with HP but when towing it is a total dog as it cannot deliver torque when it is needed.I have experience in this in driving garbage Ford trucks(if you want to call them that) for work that I wouldn’t pay a penny for.I work in an AZ copper mine and Super Poopys fall apart here, mainly the beds crack and the sides start flapping around.They are so weak that we buy sqaure tube steel flatbeds to replace them.The beds have broken in less that a week.We have some left over GM and Dodge trucks from the past and not only do they still run but the beds are all still intact!Ford(Fraud) is garbage.We have currently about 300 F250 beds stacked up in a yard that are completely useless.
G-day GMC,
I just wanted to take a moment to express my feelings. My father always told me to purchase a GMC. Finally after many years of purchasing other brand names, and upon his death I decided to give GMC a try. Well have I got a few things to say about my new truck. What a piece of soft poop. Upon receipt of the vehicle I noticed scratches on the windshield and had asked about changing it. I was told they wouldn’t change it and that the scratches were minor and wouldn’t affect the performance even though my finger nail would catch. Not even 2 months later it cracked from one of end to the other, and cost $400 out of my pocket to repair it. Yes the windshield was hit by a rock, but it might of survived if the scratches weren’t already there. After driving the truck for a day my wife decides she wants to drive. When she gets in the truck we noticed that there isn’t a way for the seat to be elevated. Now we drive around using a cushion for support and to add height so we can drive the vehicle comfortably. This is one of the biggest most disturbing things to NOT have in a vehicle never mind in a truck. Does that makes sense that a $67,000 truck has no seat height adjustment. When I asked the dealer they told me it wasn’t adjustable, nor available unless we bought a higher valued truck. WTF, seriously? Wonderful, now we drive a truck that my wife can’t see out the front window. We bought a nice cushion at Walmart, and if not too sunny out the cushion manages to keep us at the right height. If the booster seat gets too hot it shrinks, and we lose sight. My Truck has almost 25,000 KM on it at the moment but only 2500 KM on the new motor. Yes, we had to put in a new motor cause the oil hoses blew and seized it. At least we got to drive around for 2 months in a beautiful TRAX in which I paid almost $900 a month to use. It was a wonderful experience especially when trying to do the normal things you do in a truck like load construction materials, and the moving of 8ft pieces of wood. TRAX worked great, I probably scratched the dash, and dirtied the seats trying to load it so I didn’t have to cut the wood, or do multiple trips. After the new motor is installed by professionals you’d think it would be better than it was when it was manufactured by robots. Well have I got more news for you. Now the truck keeps showing error messages, and for some reason it doesn’t recognise the key fobs. I just booked another apt this week to look at the shocks, as well as the transmission. When driving over bumps, or into my driveway the shocks sound like a 80 year old truck, and the transmission keeps “banging” when switching gears. It’s embarrassing when my neighbour drives a Dodge, and has had it longer than myself but has never been to the dealership except for an oil change. I believe this will be my fifth or sixth visit, and now know the service guys by name. I’m really not satisfied with your product and cannot figure out what my father was talking about. He must have been blinded and poisoned by the chemo, and radiation. In addition to all that when the truck died for a second time in the middle of traffic, I couldn’t put it in neutral. Because I couldn’t move it I had to pay towing fees for the Police said they couldn’t wait for the roadside assistance to show up, and used their own towing company. That was $170 that I wasn’t planning on spending especially when the truck comes with it’s own tow package. Anyhow enough said. I just wanted someone to hopefully read this and feel for me for at least a minute. I will be selling, if NOT burning this vehicle asap. You’re all invited to the GMC Hotdog/Truck burning party this Saturday. All hotdogs and the burning truck will be on me. It’s really unfortunate she’s a beautiful beast, but my experience with GMC has ended… I won’t be looking at a Chevrolet either for they’re too closely related. Sadly the truck is not trustable, and I will be renting a truck for 2 weeks for my back woods holiday camping trip. Can you imagine I rented a Ford! Oh my neighbour said I can borrow his Dodge whenever I want… What an embarrassment.
Wow, what a horror story. I feel for you. I have driven Chevy trucks for years, and am a Chevy Truck Legend. That being said, I drove a new one and found it was no better then my 2015. I hate to say this, but the Fords and Rams are just nicer trucks. I think GM built this series of trucks to a price point and came up short. I will try again when the next generation comes out. I hope you can get past all this.
Ouch!
Why Chevy doesn’t focus more on quality I don’t know. It seems very hit miss – there are gems out there and dogs. My old GMC Savana with 190K has been really good. When that goes I don’t know what I will do.
Good luck on your next truck!
Yeah I’ve been a Chevy owner and lover for many years, however experiences with my girlfriends 2019 Chevy Cruze, she would go to push on the gas and the car wouldn’t even move! Dealership said it needed an update what? A car with only 23,000 miles needs a computer update seriously GM? so had to get it towed, it’s been in multiple times for re flashes and a knock sensor code that keeps popping up. Such a shame GM would make such a neat looking car and have such terrible performance and reliability issues. My father’s 2011 Impala, bought new, retarded and unreliable windshield wipers with a mind of their own” the driver’s seat belt cable broke never seen that before in my life, transmission clunks and reliability issues” not to mention almost every Impala has the tick tick tick tick noise under the dash, cob wheel has been replaced twice! My 02 Monty carlo has constant security and BCM issues which will leave you stranded and the car will not start. I’m steering away from GM vehicles after these” it’s unfortunate but reliability just isn’t there. The fact is that GM has been digging their own grave and pumping out garbage for many years now..
My neighbor bought a new Ram 1500 diesel last year……kept noticing several months after she bought it there was a different vehicle in her driveway….anyway to make a long story short…the truck was in the shop for than she was driving it…transfer case needed to be replaced….trans took about 10 seconds to move from reverse to drive….dealer said they couldn’t find parts for it so it sat for weeks at the dealership…..before it was a year old it was traded in. I’ve been a GM customer since since the early 60’s….they all have lemons occassionally……
Ford and Ram have similar issues.My brother in law drives an F150 company truck in the Phoenix area and it overheats on a regular basis,not low on coolant or a plugged radiator,just that turbocharged engines suffer in hot weather.He bought a new Ram and so far so good.However he test drove a 2018 Ram with low miles and found out that it’s a buy back due to a failed engine at 18K.The GDI carbon build up had already corroded inside the engine and a piece of it broke loose and flattened the camshaft.The F250 trucks (complete joke!) that the FMI Morenci copper mine uses are garbage.The beds(aluminum) crack and fall apart inside of a week brand new!So they had to go to a steel flatbed from a local aftermarket company to make them work.Also tons of transmission and fuel pump issues.I have driven Chevrolet trucks for 30 years and I haven’t ever had a major issue,in fact I haven’t been towed or had to walk either.I can’t say that about Ford(Fraud-work only, I wouldn’t ever buy their garbage). So you have a truck that has issues….trade it in for another.It happens to all manufacturers.However it can happen again even changing brands.
