The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the infotainment center intermittently went black, and there was water leaking into the vehicle through the top and lower center of the front windshield and the rear windshield. The vehicle was taken to a dealer, where the rear windshield was replaced without a diagnostic being performed; however, the failures persisted. Additionally, the side view mirrors intermittently failed to unfold when starting the vehicle. The contact stated that while driving approximately 40 MPH, white smoke emitted from the exhaust, the vehicle hesitated, and it lost power. The Check Engine warning light illuminated, along with "Service Electronic Stability Control", "Trailer Brake System", "Steering Assist Reduced", "Service Brake Assist", and "Brake System Failure" messages, and the vehicle failed to exceed 40 MPH. The vehicle was towed to a second dealer, Arcadia Chevrolet Buick (210 S Brevard Ave, Arcadia, FL 34266), where it was diagnosed that the lifter and torque converter had failed. The lifter and torque converter were replaced, and the system was flushed. Approximately 800 miles later, the engine failed again. The vehicle was towed to an independent mechanic, who diagnosed that the torque converter and transmission had fractured. The torque converter and transmission were replaced; however, the warning lights and messages illuminated again, and the vehicle continued to hesitate when driven over 42 MPH. After being parked for a few days, the warning lights were no longer illuminated and the mirrors opened, but the engine hesitation persisted. The vehicle was not further diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.

Vehicle: 2020 Chevrolet Silverado 1500 4x4 LT (5.3L V8 Engine) Component: Engine (Piston Rings, Lifters, and Motor Assembly) / Powertrain Component Availability: Yes, the failed components/vehicle are available for inspection upon request. What Happened and Safety Risk: While operating the vehicle on Prince Street in Clovis, NM, the engine suddenly began knocking violently without any prior warning or symptoms. Immediately following the mechanical failure, dashboard warning lights illuminated (including the Check Engine light, ABS, and Traction Control) and the vehicle dropped into "Reduced Engine Power" mode. This caused an immediate and hazardous loss of acceleration on an active roadway, forcing an emergency maneuver to navigate out of traffic and pull over safely. This sudden powertrain failure poses an unreasonable and severe safety risk to the driver and surrounding traffic. Confirmation and Inspections: The mechanical failure has been confirmed and diagnosed by Hamilton Chevy in Portales, New Mexico, and Sanders Repair Services in Portales, New Mexico. The vehicle and components have not been inspected by the manufacturer, police, or insurance representatives. There were no warning lamps, messages, or symptoms of any kind prior to the sudden failure.

Power train, Wheels, Fuel/propulsion system, Aug 19, 2026
While driving at highway speed, my vehicle developed a serious transmission problem. At approximately 75 mph, it suddenly lost the ability to maintain speed and dropped to about 55 mph despite throttle input. Engine RPM increased significantly and the vehicle had greatly reduced propulsion. Normal operation temporarily returned after the vehicle was shut off and restarted. The vehicle has also experienced harsh shifting, vibration, limp-mode behavior, a check-engine light, and I reported a momentary wheel-lock event. These symptoms create a safety concern because an unexpected loss of propulsion or abnormal transmission behavior at freeway speeds can increase the risk of a collision. The vehicle was inspected by an authorized Chevrolet dealer. The dealer documented transmission-related diagnostic codes including P0700, P0970, P0968, and P0711. The dealer's repair order specifically referenced GM program N242454441-03, described transmission control-valve wear and pressure loss, and recommended replacement of the valve body. A separate repair estimate included the valve-body assembly and related transmission service parts. Despite the dealer recommending valve-body replacement, GM/dealer coverage was denied primarily because P0747 was not present at the time of diagnosis. I am reporting this because I am concerned that transmission control-valve/valve-body deterioration may cause harsh shifting, reduced propulsion, limp mode, or other safety-related symptoms before or without P0747 being stored. I am asking NHTSA to review whether vehicles with the same underlying valve-body failure may remain on the road because the specific qualifying diagnostic code is not present during a dealer scan. The vehicle and transmission are available for further inspection if requested.

I'm experiencing all the documented issues with the 10L80 10 speed transmission. Identical to all the recalls. It's shifting poorly, torque converter shudder, lose of power, unreliability, and serious safety concerns. I've tried to communicate and find a resolution to these issues through the dealership and GM. Of course getting nowhere. I don't feel a 60k dollar truck should be in this kind of condition. Recently the ac compressor went out. Conveniently after the 6.2 was considered faulty and was replaced but transmission denied. Which the dealership GM expressed in no way was any factors the warranty companies claims of a taller tire being on the truck. Being the issue at all for the transmission failure. Also the dealership didn't check a box. One that I can not physically check. Which they put on me. They swapped the stock tires to the taller brand new set I'd just bought for my trade in. Never stating anything about the tires being taller voiding the warranty I just paid for. Why would I deny the part of the extended warranty that I wanted. Cause of the suspension and drivetrain. Either way this truck is not safe to be on the road. It struggles to maintain speed on the highway. Eventually leading to the torque converter free spinning and making all kinds of noises and vibration. Of course once I've assisted it to violently shift through the gears and hopefully into 10th. On occasions it never makes it that far. Either way I feel this falls directly into the recalls with the same model and year. They replaced the 6.2 cause of cylinder failure and oil consumption. Well the next in line for the drive train is the junk 10 speed. Not sure how it can't be related. The long and stressful time. I've put into finding a solution with the dealer or manufacturer. They blow me off or just don't give me any info. I feel that's their way of dismissing not only the failure of the salesman not properly doing his job. Which the GManager also stated mistakes happen. Not OK

GM has a known recall and special coverage N242454441 to cover the exact same issue I experienced on my way home from work. However, I am informed my model is not included in this special coverage. The issue I experienced while attempting to turn into my apartment complex on a busy road [XXX] my rear wheels locked up mid turn no warning signs, no lamps, no messages or other symptoms were present. Almost causing me to get into an accident had traffic not stopped. I was able to shift it into park and then to drive to immediately pull off to the side into a parking lot and put my OBD reader I have P0747 solenoid 1 failed locked on. I was informed by GM that they could attempt to reprogram the transmission control model, however based on research this is not the root cause of the issue it is due to the soft aluminum bores causing the transmission module to ware and fail.

Our truck started hard shifting and lurching almost a year ago, the check engine light will come on, sometimes the truck will go into safety mode, then the check engine will be off. The problem progressed and we had it diagnosed as a bad transmission control valve which we were made aware is not available to get replaced because of the ongoing recall on other vehicles in the same year range as ours, just not ours specifically. We need to get this fixed and if others are getting it fixed on recall ours should be as well. Otherwise we have a barely usable vehicle, that my husband relies on to get to work, sometimes hours from home, with no way to fix it, a year left of payments, and diminished value because of the transmission issue...that again others are getting fixed at no cost to them. Even without the recall we can't get it fixed because all available parts are going towards the recall. We deserve to have our vehicle added to this recall so we can get in line to fix it. We have been loyal customers for over 20 years to our local dealership Rydell Cheverolet. The incident date is ongoing for over a year but I will put in the most recent date where my husband was almost stranded 300 miles from home.
