I was driving on I-35 in Norman, Oklahoma, shortly after 7 am, when my 2020 Chevy Trail Boss with the 6.2 engine stopped running. I was in moderate traffic and shifted the gear shifter to neutral, and the motor would not restart, leaving me in traffic. I was able to slowly get on teh shoulder to avoid a collision, and the engine would not restart. I had teh vehicle towed to Ammco in Norman, Oklahoma, where it was determined that a catastrophic engine failure occurred. This is teh same problems that are associated with recalls on the 2021 and up 6.2 GM engine. luckly i was able to get to a safe place and avoid a collision.

I am writing to formally report a persistent and dangerous manufacturing defect regarding the rear window and seating assemblies in my 2020 Chevrolet Silverado. I have already had GM replace the rear window in 2023, it needs replaced again now in 2026. The rear window seal is failing, allowing a significant amount of rainwater to leak into the cab. Because of this ongoing water intrusion, the structural base and brackets of the rear seats have developed severe rust. Furthermore, I am deeply concerned that this constant moisture saturation is creating an unseen mold hazard within the cabin, which poses a direct health and respiratory risk to my passengers.This leak also risks damaging sensitive electrical components and wiring harnesses located under the rear seats and trim panels, potentially causing short circuits and sudden failures of critical safety systems while driving.Many other owners of this generation Silverado have reported identical issues, including cracked plastic frames around the sliding rear glass that cause the leaks. Because this defect compromises vehicle integrity, creates a risk of electrical failure, and poses health hazards from mold, I am requesting that the NHTSA investigate this issue as a potential safety defect requiring a manufacturer recall.

While returning from a camping trip my engine lost power. luckily I was close to an exit and managed to get it off the expressway and to a parking lot. I was able to leave the camper in the lot and have the truck towed to a dealer 30 miles away. I was informed by the dealer that the engine had sustained major berring failure. I was over 500 miles from home and I had 2 options, wait 2 weeks for a new engine to be installed or trade it in for a new truck. I opted for the trade in because I didn't want to wait 2 weeks. I figure I lost $7000 in trade in value and had to spend $2000 to have my new truck fitted for a 5th wheel hitch.

Sliding rear window leaking, causing mold and ruined seats. Had it "fixed" in 2023 only 3 years of owing it. Now here 3 years later the same issue is occurring and they're not willing to make it right. Mold causes a safety hazard for my children and anyone in my vehicle. My truck only has 30,000 miles on it and I shouldn't be having this issue

* same part gone bad as other recalled vehicles. "Coolant control flow valve bad". Engine fan is staying on high blast, message displaying " engine power is reduced" truck will not drive at full power because the truck thinks its overheating because of bad part. If i remember correctly, it is code p1098. Bad part is intermittent. It Will happen randomly driving down the road. It comes and goes. I believe this is a safety factor . There is a special warranty or recall regarding this part with my year truck, but not my vin? Why not? Same part going bad with same codes and same problem ? Please consider looking into this concern and expanding the recall or concern for this reduced engine power safety concern. Thank you for looking into this.

I am reporting a failure involving a 2020 vehicle equipped with a GM 6.2L V8 engine that developed a cylinder 8 misfire along with diagnostic trouble codes P0300, P0500, and P0521. Dealer inspection revealed a severely scored camshaft and metal debris present in the engine oil, indicating significant internal engine damage. The failure appears to be related to a lifter or valvetrain malfunction, leading to improper valve operation and engine misfire. This issue occurred unexpectedly and creates a serious safety concern due to the risk of sudden engine failure during operation. This may be associated with known problems affecting this engine type and should be investigated further.
