ENGINE
* 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.

POWER TRAIN
The transmission, without warning, intermittently locks the rear wheels when towing a 13,500 lb 5th wheel RV. It occurs when going uphill and the transmission downshifts to maintain torque. The "D" on the gear indicator on the dashboard also flashes 3-5 times. This is a known issue with the Allison approved (but GM made) transmission from model year 2020 to 2022 (NHTSA 24V-797) and is to be under extended warranty. We brought it to a Chevy dealer who kept from March 24 to April 9, without any resolution as they could not replicate the error which only happens under load travelling uphill. I also openedd a case with Chevrtolet Customer Service, who apparently does not have any ability to compel GM corporate techs or dealerships to fix the issue described without an error code. Historically, the truck throws error codes routinely and we have spent several thousand dollars trouble shooting the communication issues, also without resolution. We live in Wisconsin and were on vacation near Los Angeles, CA and had to transport it back home, leaving our RV in storage in California. At present, the only path to repairing the truck is to pay for the transmission repair ourselves. GM still does not have a long term solution for the tranmissions they now manufacture.

ENGINE
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.

ENGINE
I was driving at approximately 75 to 80MPH on the highway when my engine shutoff and the vehicle died while driving it. I was able to coast to the side of the road but had to cross two lanes to the left to do so while weaving in traffic to get to the shoulder of the road. There was no warning of any kind that would have made me aware of an issue prior to this happening. I was unable to get the vehicle started again and had to have it towed to my local dealership Hendricks Chevrolet in Columbia, SC. That occured on Saturday March 14th 2026, that Monday, I have had all regular and scheduled maintenance done to my vehicle either on time or prior to the recommended time including oil changes and the like. I went to the dealership and they told me that the engine had seized up and that this was a very well documented and common issue with the 6.2L L87 V8 Engine dating back to 2019 but that GM had only issued recalls on the 2021 - 2024 years to correct the issue. I asked the Service manager at Hendricks Chevrolet to file for a Goodwill Coverage request on my behalf to cover the repairs of the engine and he refused and stated that I had to do so through GM customer service line. I have done so since and my case number with GM is 92108267. My vehicle is currently at the dealership awaiting the go ahead from GM to replace the engine. I have an extended warranty on my vehicle that goes to 120,000 miles and the issue occured at 114,113 miles. This is a very well documented case where the engine connecting rod bearings fail due to oil starvation that leads to engine seizure.

SERVICE BRAKES
Started to work first thing in the morning, the truck felt sluggish-like a lack of power. I drove about a mile to turn around and head back home, something was obviously wrong. When I got out of the truck there was a smell like something was hot and the wheels were extremely hot. I realized the lack of power was due to the brakes being locked. The parking brake was not engaged. After calling the local dealer for an appointment, I had to get the truck towed. Now the 2nd day at the dealer with no diagnosis, no service codes. The truck has approximately 77,000 miles with the original brakes from the factory and have never had to be replaced. The vehicle data display shows 42% of brake wear remaining.
