2021 CHEVROLET SILVERADO 1500 Complaints

The Vehicle that I own is a 2021 Chevrolet Silverado 1500 with a 6.2 liter engine. on 6/2/2025 i went to have the oil changed and the service technician informed me there was no oil in the engine. He also informed me that this particular model with the 6.2 liter engine had a recall relating to components in the engine. After researching I found that there was in fact a recall, but my truck was not listed on the NHTSA web site. I made a visit to the local dealership and the service manager informed me that there was in fact a recall but there was nothing they could do at this time. He suggested that I check the oil level every 500 miles and wait on a recall notice. Now the engine is starting to make internal noises that concern me greatly. There is a opportunity that the engine could simply lock up and there is no certainty on what might happen. Please advise

Vehicle started with vibration at speed 45mph and sometimes it gets worse already balance the wheels twice and same issue so I took it to another shop and they found that my vehicle has hesitation and shuddering also really hard down shift

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while leaving a parking spot and driving approximately 5-10 MPH, there was an abnormal knocking sound coming from the engine before the vehicle lost motive power. There were no warning lights illuminated. The vehicle was towed to the local dealer and was diagnosed with engine failure. The vehicle was repaired. The contact stated that the vehicle had experienced catastrophic engine failure two years prior to the recent failure. The manufacturer was contacted and informed the contact that the VIN was not under recall. The failure mileage was 20,000.

I am facing my second coolant control valve replace in the last 10k miles. The truck errors with a code of P1098 due to the valve failure and the fan continues to run. My truck was then put into limp mode. This valve is a know problem with this motor and not cover under warranty.

I was on my way home from work on [XXX] coming around the lakes with no median or shoulder when the engine in my 2021 Silverado started rattling, temperature gauge started going up, and losing power. Within a matter of minutes my truck shut off leaving me stranded in the middle of a four lane highway with no safe location to stop. The engine wouldn’t even turn over to try and crank back up so I could get the truck out of the road. After help getting my truck to a safe location I noticed oil and antifreeze leaking out of the bottom side of the engine. This truck was at Love Chevrolet for engine failure on 8/14/24 and was told it was fixed and was never told about ongoing issues with this particular 6.2 engine. I found out a few weeks ago while trying to trade my truck in to Jim Browne Chevrolet dealer that my particular truck the 2021 Chevrolet Silverado High Country with the 6.2 engine had known issue with the engine locking up and was afraid to take my truck in on trade due to his service manger going through this same experience. So I paid top dollar for a high end Chevrolet truck to be stuck with not being able to trade it and now not being able to drive it. I called the dealer and was told that my trucks vin number was not part of the recall for this issue but there are trucks that are the same year, model, and engine type that are covered under this recall. I’m now stuck making a 850 a month payment on a 58000 dollar truck that I can’t drive and can’t afford to replace an engine. Any help would be greatly appreciated.

While driving my truck at approximately 50mph it suddenly lost power while in traffic. I was fortunate enough to pull over safely to avoid an accident. The motor was violently shaking and sounded like it was coming apart internally. Almost every warning light on the dashboard came on as I was pulling over. The truck had little power and did not sound normal. I immediately called for a tow truck and had it towed to the nearest Chevrolet dealership. After inspection they confirmed the lifters were bad. The truck had 38,000 original miles on it at the time of this incident. The dealership repaired the defective lifters. With the current GM recall on the 6.2 liter engine my truck does not qualify as it was built 1 month prior to the recall date. This truck needs to be included in the current 6.2 liter engine that GM is recalling. The motor is defective and is a major safety issue. If I was driving with my family on the highway while this abrupt incident happened it could have been catastrophic. There were no signs or warnings whatsoever prior to this incident.

Took my vehicle in on 3/24/2025 for an oil change and to check a perceived issue with transmission hesitation and a noise. Tech confirmed and repaired an issue in the transmission and also confirmed an issue within the engine. A replacement engine was ordered. Vehicle is still at the dealer awaiting the engine with no estimate as to when the engine will be shipped or received. It has now been well over 2 months. A loaner vehicle was provided on 4/30/2025 but is not comparable to my vehicle.

Engine failure with no warning. Driving home from dinner, made a right at a stop light and then warning lights and knocking sound in engine compartment, truck noticeably shaking

First my engine light came on and as I was in my way to the dealership I lost my brakes. It stayed at the shop for a week before I was contacted only for them to tell me that there was metal shaving in my engine oil and they recommend full replacement, meanwhile haven’t even made it to my brakes. GM offered me 3K toward replacing the 13K+ engine. That’s so unacceptable!

The contact owned a 2021 Chevrolet Silverado 1500. The contact stated that while coming to a stop, the contact heard a loud sound coming from the engine compartment. The check engine warning light was illuminated. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the repair was unavailable. The vehicle was taken to the dealer, where it was diagnosed and determined that the connecting rod and the crankshaft engine components had failed, and the engine needed to be replaced. The vehicle was not repaired, and the dealer confirmed that parts were not yet available. The manufacturer was not made aware of the failure. The failure mileage was approximately 70,000.
