471Sponsored Links
The Chevy Silverado and GMC Sierra are hugely popular pickup trucks, but now, both nameplates have been singled out as having major engine issues and reliability problems.
Per a recent post from non-profit consumer organization Consumer Reports, the Chevy Silverado and GMC Sierra are tied as the recent models most likely to exhibit major engine problems. The Chevy Silverado and GMC Sierra are both pointed out as “they’re the same trucks sold under different brands,” according to Consumer Reports.
Consumer Reports listed several vehicles most likely to exhibit reliability issues in the organization’s 17 key trouble spots, which, in addition to Major Engine issues, also includes Engine Cooling issues, Major Transmission issues, Drive System issues, Electrical System issues, and Climate System issues.
Notably, the 2020 Buick Encore GX was the vehicle most likely to have brake system issues.
The Consumer Reports ranking is based on reliability data collected via Consumer Reports member surveys, and focuses on 1- to 3-year-old models.
According to Consumer Reports, 4 percent of Chevy Silverado and GMC Sierra owners reported some kind of Major Engine issue, including full engine replacements, as well as cylinder head-related issues. Major engine issues include an engine rebuild or replacement, cylinder head problems, head gasket problems, turbocharger or supercharger problems, and timing chain or timing belt problems.
Overall, Consumer Reports gives the 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 one out of five with regard to reliability scoring.
As a reminder, the 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 were both offered prior to the full model refresh introduced for the 2022 model year, as well as before the pre-refresh 2022 Chevy Silverado 1500 Limited and 2022 GMC Sierra 1500 Limited. Engine options for the 2021 model year include turbocharged 2.7L I4 L3B gasoline engine, naturally aspirated 4.3L V6 LV3 gasoline engine, naturally aspirated 5.3L V8 L82 gasoline engine, naturally aspirated 5.3L V8 L84 gasoline engine, naturally aspirated 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax.
Both pickups ride on the GM T1 platform.

Your pres this and your pres that. Grow up. 1st whom ever is elected like it or not, IS your pres. The Frito Cheato left a mess and only now says get vaxed. Next this is where we rave or rag out on the General not Your personal grievance site.
If it takes Consumer Reports to wake up GM about bad engines, bring it on! I have owned every size pickup GM builds over the last 49 years and they have been great trucks with great engines until I bought my 2015 GMC Sierra SLE 4×4 5.3l. I bought the truck used with 54,000 miles and after driving it for about 400 miles the engine crapped out. I had to have the replace the lifters, cam, oil pump and push rods replaced at $5200.00. GM told me too bad you’re the second owner, we can’t help you. So, I say whatever hell Consumer Reports can raise to help some of us recoup are loses, bring it on!
Doesn’t CR rate Toasters and alarm clocks? Oh and all automobiles?
So true!
Yes… If you buy it.. they probably rate it . As long as someone at the General reads it.. It’s a good thing.
I see a lot of junk talk here but no actual info on what motor is bad or amount of failures
I have owned a 2009 Denali , and 2015 Denali had to have both transmissions repaired .
I have a 2015 GMC Sierra Denali and I have replaced the lifters on both sides separate times in two years. Also I’m having problems out of my air conditioning leaking refrigerant. I love my truck but it comes with a lot of problems.
As a technician I see that GM”all over the board are terrible, the amount of vehicles I see that are from 2010 to 2018 GM terrains, Buick, Chevrolets are horrible the amount of engines replacement out of warranty and no help from the dealer . They have silent recalls if you b**** loud enough they might help. GMC stands for gotta mechanic coming, save yourself some grief and aggravation and buy a Ford
Have a 2013 silverado Z71 extended cab 4wd with the 5.3 v8. It had an oil flow problem where cylinder 7 was getting flooded with oil and mis-firing. The dealer replaced the valve cover (“old style” whatever that means) and it solved the issue. I was told that if it had not solved the issue, it would have been an engine replacement. No other problems at 105,000 miles.
When is the Barra nightmare going to end? It is just one thing after another. The problems range from the Chevy Bolt fires to GM falling behind Toyota in US sales. In the last decade, we have seen GM sales and reliability drop dramatically. It is disheartening to be a GM fan today.
Bought my 2021 Silverado LTZ, 5.3, and back in Sept. 2020, was on my way home, when it started back firing. Dealership had it towed in, found a lifter on the passenger side collapsed. They had it 2 1/2 days, changed all 8 lifters on that side! I hate the fuel management system!!! I had just a little over 6000 miles.
Here’s the problem guys, Mary is too busy getting all of the electrics into production,so she’s letting the production of the ICE to go to ( h###) wither away.This to me is a bad excuse to change peoples minds. With all the negative comments above,these are the people that won’t buy GM again. Now this is coming from a big GM fan. Our family ,going back to my father’s time that’s all we bought GM Chevs/Pontiacs/Olds/Buicks I have to say this was from 1953 to 1993. In fact I still have a ’93 Olds Cutlass lingering upstate NY. but here’s the punchline ,somewhere around 2003 I needed a new car and unfortunately GM had nothing to offer ,so I made a bad mistake and bought a Ford Windstar van. It was pretty trouble free and I drove it to about 160000 miles when Ford recalled it for a possible safety defect at160000 miles. They gave me the option of repairing the car or they would buy it back. Needless to say that was an easy decision.Ford gave me 4 times what the car was worth and I still have the second row of Captains seats to boot. So what do I do for a car,I Iooked at the GMC Acadia and as a GM fan was totally dissapointed. So I went back to the Ford dealer that bought the Windstar and ordered a new 2011 Explorer. Now after 11 years of all sorts of driving and trailering a 4000# car at times,my explorer is still running fine,with very few repairs .At 196000 miles I’m still on the original drivetrain. By the way when I hit 228000 I can brag that I drove to the moon…
To all of you one question.. what happened to the truck? Morons
540,000 mi on my 1 st,Chev silv 4×4 it sold still see it running,,my 2 nd Silverado 4×4 like new w180,000 I’m expecting the same I’m a Chevy fan from old days not stranded ever well once 45 yrs ago timing belt on Chev luv pu PS for the coxid your clueless and brainwashed

Blown headgaskets wouldn’t be the first for GM. You’d think they’d learned from their folly with the Cruzes.
Usually something a slightly thicker headgasket can solve. They suffer from iron block, and aluminum cylinder head issues. Also too high compression ratios, that seem to induce pre-ignition. Very common on their turbos, and especially true in hot weather and under heavy load!
Yo tube una 2014 Chevrolet Silverado 1500 5.3
Y se le quemó la trasmisión y se me arruinó 2 beses del sistema de frenado alos pocos meses me dió problemas del motor y quebraba el aire acondicionado y la cambie por un 2019 Silverado 2500 6.6 duramax este ya lo tengo mas de 2 años y no me adado problema y todos los días jala remolque
Chevy trucks are junk. My chevy truck has lifter problems and electrical problems. I will not buy another. I have friends with same problems.
I had a 2018 F150 in 2020 my lease was up and I went for a 2020 Silverado 5.3… after 6 months it suffered major coolant loss and resulted in a replacement engine, then the second engine suffered from excessive oil consumption…. My F150 3.5 Ecoboost had ZERO problems whatsoever.. I got rid of that GM turd and went back to a 2021 F150 3.5 Ecoboost, it’s been a year now and over 50k miles and it’s been solid no matter what I throw at it
We are seeing late 1970s reliability here. GMs new. Trucks are pretty weak.
