2021 Chevrolet Silverado 1500 complaints

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the tailgate became inoperable and unexpectedly unlatched and lowered. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 65,000.

I have a Chevrolet Silverado 1500 with the 6.2L engine. I received the recall notice about the loss of propulsion due to a crankshaft issue. The safety of myself, family, friends and coworkers who ride with me on an everyday basis were put at risk because of the faulty engine. I brought my truck in for an oil change in August 2025. I had the Team Chevrolet dealership in Las Vegas Nevada do a telescopic inspection to see if my particular engine had the recall issue. It was discovered the engine did have the recall issue and was kept by the dealership for roughly two and a half months. Chevrolet has confirmed this is a major issue and is affecting roughly 600,000 people. There was no sign of the issue before the telescopic inspection but since the engine has been replaced I have now had three separate issues with misfiring cylinders on the new engine. The plugs and wires have been replaced twice and has not resolved the issue. When the misfires have occurred there were error codes, check engine light notification, and engine sputtering. This again has endangered the safety of myself, family members, friends, and coworkers who ride in my truck on a daily basis. This is now going on four months of issues that keep persisting and I am very concerned that both the manufacturer Chevrolet and the Team Chevrolet dealership are not taking the proper steps in order to solve this very serious issue.

Not sure of exact date I believe it was right before Thanksgiving. The truck started shuttering and vibrating. It feels like we are driving on a gravel road. the manual said to change transmission fluid between 45,000 and 60,000 so we took it to the dealer. that is what we did hoping that would fix the problem. but it did not so we took it back and they kept it for 3 weeks they said no codes came up and they said the tires needed balancing so we let them do that but the problem is still there. they say there is no recall on it . we did some research and found information stating Chevy is having problems with the transmission. as of now we only have 45,608 miles on it. It is riding worse now.

The coolant control valve has failed, my vin isn’t a part of the special coverage for this bad part ( though the same part and model is covered)

2021 Silverado 19,000 miles no indication of failure at a busy intersection about to go thru intersection and engines started knocking, multiple check engine lights on. Luckily got thru the intersection and to my place of residence which was very close by. Truck was towed to Chevy dealer. Dealer found 3 bent push rods, 3 bad valves. This engine had the lifters fail completely out of the blue. Oil changed at the dealer, meticulously maintained. Dealer only replaced the faulty bank of lifters due to mileage, seriously if it was under 16,000 they would replace all of them. This is unacceptable. This truck left me almost stranded in a busy intersection, lucky I knew well enough to keep going versus getting T-boned. I just think GM needs to do something about this. Now fast forward to 41K and I'm at the dealer same symptoms except this time my warranty is running up soon and being forced into an extended warranty. There are plenty of online claims, chat rooms, posts, etc to warrant this as a safety issue.

I looked to see if there was a recall or anything. Sure enough there was. 2021-2024 Silverado 6.2 liter engines for crank shafts and connecting rod malfunction. I'm curious how my 2021 6.2 liter Silverado that has a connecting rod sticking out the side of the block is not part of this recall?

A week or two before I took my truck into decorah Chevy isr because tailgate was going up and down all by itself while I was driving or parked without me by it. They said it was just the latch button . So they fixed it they said and still my blinker lights would just come on and then I hit a deer and my seatbelt did not latch and my airbags didn't deploy even though my app says they did. I'm wondering if all three are connected with electrical . Either way my air bags did not deploy and my truck has extensive damage and my seatbelt didn't lock ,

In January 2024, I experienced an engine failure in my 2021 Silverado with the 6.2 Engine. My VIN was not part of the recall affected VIN units built in 2021-2024, it seems to have been built a few months before the last affected group, In any case, I noticed the engine stumbling, and the check engine light came on. I was able to drive the truck home, and when I went to start it the next day, the check engine light was off, so I drove it, and the engine stumbled the check engine light came back on, so I took it to the dealer. They read the codes, and cylinder 5 was misfiring. When they put a scope in that cylinder, the cylinder walls were scored, and there was oil in the cylinder. At that point the dealer chose to replace the engine with a remanufactured engine with no additional warranty added, or any other remuneration for the inconvenience. They did not share with me any specific reason (Lifters / Camshaft / something else) for the engine failure.

The vehicle has been showing a “shift to park” message error upon shutdown even though the vehicle is fully in park and door automatically unlock when parked. This has left the accessories on and drained the battery

The brake stopped working. I just bought the car two months ago.

August 30th 2024 the pickup was just turning to roughly 30,000 miles and started a knocking sound. The GM dealership tore it apart and fixed what I believe they said was a bent rod. I cycled through two oil changes and decided to pull an oil sample. I sent oil sample off for analysis. The oil analysis came back urgent with very high levels of copper and lead showing in the testing. I then called the GM dealer and they had me bring it in. They did not send off any oil sample because when they pulled the filter, they could already see metal in the new oil. They had me call GM customer service because it is not part of the current recall. I contacted GM customer service on October 27, 2025. They gave me a case number 80392504. I was to bring it back to the dealership which I did. Again dealership called said metal was found again but GM will not do anything with it because it’s not under recall. They also told me that GM told them it is OK to have metal in the oil. I said well if it is OK to have metal in the oil I want to know what the test results show. Then I said, I want to know where the maximum allowance is. They did not know that. I said so it is an infinite amount according to them because there is no standard to check against. I said I’m not taking this in for a recall. I am bringing it in because I had my own diagnostic testing done. It failed. I drive back-and-forth to North Dakota and I told them this is very unsafe if that motor goes out and it’s -30 or -45 and my l

My truck was brought in for the recall inspection for the 6.2 lt recall. After showing the dealer pictures from the oil that drained out of my previous oil change that was filled with metal, they expedited the inspection. But with substantial amount of metal in the oil filter the truck still passed the test. GM corporate has told me that once the inspection is done, it is out of their hands and that my truck will be covered under the new extended warranty. GM also should have the pictures of the metal flakes from the previous filter. I fill like this is a failure to ensure the safety of their product. I do not fill safe having my children or my wife in the truck due to the inevitable of the engine loosing power due to the faulty cam shafts that need to be replaced.

6 months and 20,000 miles after purchasing the 2021 Chevy Silverado custom 4x4 with the 8 automatic transmission and the 2.7L turbo charged engine with 32,000 original miles on it from Volume Chevrolet in Forsyth GA I noticed the transmission was jerking when the truck was first crunk and warming up after about 10 minutes and once it got to 8 mph after a while when the temperature gauge was half way up it would stop and when you slowed down from 55 mph to about 5 MPH to make a turn it would suddenly jerk again, I reported the issue to the dealership service mechanic shop reps during every oil change and they assured me that it was normal and that it would stop happening when I let the truck warm up for about 30 minutes prior to driving, once the factory power train warranty ran out, they informed me that it needed a transmission service and they would have to keep it a few days and it would cost around $800 or so to get it done, the purge pump on the emissions system has a factory defect and I received a recall letter about it 6 months after purchase and they are refusing to replace the purge pump until they perform a full diagnostic first even though they have done a scan diagnostic and it shows the purge pump failed and I have just been struggling with all the cost of living and increased prices I can't afford any kind of costly repairs right now and my truck now has 120,350 miles on it and the issue is getting worse to the point that I am sure that the transmission valve b

Vehicle experienced engine failure while driving. Loss of power in traffic. Inspected by dealer and determined to have lost compression in cylinder #5. Initial inspection determined that lifters and camshaft would need to be replaced. This issue is the same common problem with this year model (2021) Chevy Silverado Trucks as noted in TSB #N212353840. At time of purchase dealer did not notify me that these trucks were experiencing these issues nor did they complete the suggest repairs prior to the sell as described in the TSB.

My engine on my 2021 Silverado 1500 with the 6.2L L87 engine failed, I took it to the dealer to repair and they quoted $4500 to fix it. I know these same engines are being recalled and GM is having to replace them, but they told me mines not one of the ones being recalled and the won't cover it because the warranty was up 5,000 miles ago. I highly doubt it's a coincidence, that mine failed after only 65,000 miles and it's not a manufacturer flaw. The vehicle is currently at the dealership awaiting repairs.

Engine is knocking very bad. GM Dealer says it is an issue w/ the piston main bearing and the engine needs to be replaced. Says vehicle should not be driven.

Component is transmission. Stutter vibrate shift while driving. There is a recall on the 2021 Chevy 1500 Silverado which is exactly the issue we are having from our 2021 Silverado. The VIN for our truck is falling under the current recall. Chevy wants to charge to even diagnose the problem which has to be done with a dealer and not a private place. That is absurd and puts our safety at risk should the vehicle stop functioning while driving it. The dealer ship has inspected the vehicle for the yearly inspections which is interesting since this has happened and been complained about since purchase.

I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately.

GM 6.2 engine recently tested for the national recall regarding valve and lifter issues. Recall was cleared as ok, but they found burnt cylinders in multiple areas within the engines. Several issues are still occurring with this engine, and I think most are related to the recall effort. 1. Engine will use oil at an abnormal pace when towing anything heavy. Recently used an additional 2 quarts of oil when towing a trailer that weighed 10, 000 pounds over 1600 miles. 2. Recently engine seemed to lose compression at a stop light and turned off. This happened an additional 5 times until I could get the truck off the road and into a safe place. The engine would immediately start and then die within 5-10 seconds. Towed to a Chevrolet dealership and the service manager tried to move it into the bay for diagnostic testing. started and stopped 4 additional times as they attempted to drive if 100 feet into the service bay. Towed to my hometown dealer that afternoon for diagnostics testing. The next morning when they started the truck it cranked fine and has been running since (7 days). No lights appeared on the dash during the breakdown or warnings appeared in their testing I have spoken to several other Chevrolet owners about the 6.2 engine issues and what was occurring with my truck They also had seen an increase in oil usage when towing heavy. I believe that your investigation needs to delve further into not only issues with the lifter / rods but also into other mechanical concerns

Vehicle was at a stoplight with the auto start button engaged on it. The vehicle completely stalled. All the power is drained from the car. leaving me stranded in the highway. I got it towed and when replacing the battery still nothing will roll over or even turn on.

Engine just died going 55 mph on a paved road. GM repair shop says engine needs to replaced. They originally told me my 6.2L engine was a recall, but my VIN didn’t show on database. Seems GM’s scope was not wide enough on their recall. I feel I deserve a new engine.

The truck started to vibrate badly. Brought it to the dealership and have to replace the 6.2 L engine. I was happy to make it home without it breaking down. The truck only has 67,000 miles on it.

Started with a clicking noise that mechanic thought it was the fuel pump but found out later it was the bearing is the rocker arms that failed and ruined the camshaft. Now it needs a new engine.
