ENGINE, FUEL/PROPULSION SYSTEM
Failure of the coolant flow control valve and DEF component. Caused the engine to overheat and potentially fail while driving. The part to repair this problem has been very difficult to obtain causing a prolonged period of time in a repair shop. According to online forum information this an ongoing problem with this particular engine for over 4 years now. In my general area there are 6 vehicles that are in need of this particular part before they can be repaired. This is definitely not an isolated incident.

POWER TRAIN
At approximately 67,000 miles I noticed upon starting and putting it in gear the motor would rev/clunk while going into gear. Shifting from one gear to another the truck would shutter. Did not feel safe driving any distance because the truck would lock up when trying to put it in gear. I had the truck looked at after reading numerous complaints about this 8 speed transmission and wanted to make sure it was safe to drive. After test driving it a couple of times during the course of a day it was determined the transmission needed to be replaced/rebuilt. At no time did any warnings appear on the display indicating there was an issue. I had the transmission rebuilt but feel like there are many complaints and no recalls regarding this same issue.

ELECTRICAL SYSTEM
My 2021 Silverado has the same issue as the current recall, whereas the tailgate open by itself when the vehicle is operations. This happens when it rains. The first time I noticed it I lost a cooler out of the back of my truck on the interstate highway. The second time it came down when hauling a trailer and cause minor damage to the tailgate. I have since removed the fuse that controls the tailgate. I notified Chevrolet of the issue, but the stated that my truck is not under the current recall.

ENGINE
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

ENGINE, STEERING, AIR BAGS
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.

ENGINE
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.
