While driving I lost the power steering on the vehicle. I took my truck to a chevy dealership and scheduled an appointment for the following day. I research the problem and found that there was a Customer Satisfaction Program bulletin (N252515590) issued covering this specific issue for my trucks model year but it did not cover my specific VIN. I contacted Chevrolet Customer Assistance and they told me to file a complaint with NHTSA.

What component or system failed or malfunctioned, and is it available for inspection upon request? The A/C condenser and the vehicle battery failed. The failed components are available for inspection upon request. How was your safety or the safety of others put at risk? The A/C failure causes the driver's side to blow warm air, creating severe window fogging and reducing visibility in extreme weather, while the electrical/battery failure compromises vehicle operation and safety features. Has the problem been reproduced or confirmed by a dealer or independent service center? The A/C issue matches General Motors Technical Service Bulletin PIT5767A, caused by an internally bypassing condenser due to a mispositioned block-off plate. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has not yet been officially inspected by a manufacturer representative, but the defect aligns with known GM manufacturing specifications under bulletin PIT5767A. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Symptoms appeared suddenly with the air conditioning losing performance (driver's side blowing significantly warmer than the passenger side) alongside concurrent battery and electrical system failures.

Rear axle locks up and transmission goes into limp mode , this happens when slow speed under acceleration, this happens almost any time in traffic , at stop light , acceleration to freeway. a safety issue, shows a p0700 code and p2729 code , engine service code light goes on , T/C and skid lights. also happen at hard brakes in traffic lights or fast slow downs

The contact owns a 2020 Chevrolet Silverado. The contact stated that while driving between 20 mph and 60 mph, the vehicle shudders a lot while accelerating. The vehicle was taken to an independent mechanic where it was diagnosed with a failure in the transmission. The contact stated he contacted a dealer where they confirmed the failure but stated there are no recalls nor TSBs related to the failure, although there are recalls for different model vehicles that have the exact same transmission as the contact's vehicle. The contact referenced TSB 19-NA-121 (powertrain); however, the VIN was not included in the repair. The contact stated he could feel the shaking shuddering. The manufacturer was notified of the failure. The vehicle was not repaired.

While driving my 2020 Chevrolet Silverado 1500, the braking system suddenly malfunctioned without any prior warning. When I released the accelerator, the vehicle began slowing as though the brakes were being applied even though I was not pressing the brake pedal. When I attempted to brake normally, the vehicle did not stop as expected and braking ability was significantly reduced. The red BRAKE warning, ABS warning, traction/ESC warnings, and check engine light illuminated. The dashboard displayed “Brake System Failure – 43 MPH Top Speed,” “Service ESC,” and “Service Trailer Brake System.” Because of the reduced braking ability, I stopped the vehicle and had it transported by flatbed tow to a Chevrolet dealership rather than continue driving it. The Chevrolet dealer inspected the vehicle and documented diagnostic trouble codes P25A2 and C053D. The dealer stated that the Brake System Control Module requested the warning light and that updated software was available to address these codes. The dealer reprogrammed the Brake System Control Module according to a GM technical service bulletin. No mechanical brake components were replaced. I was charged $362.95 for the diagnosis/reprogramming. I am reporting this because the failure occurred suddenly while the vehicle was being driven and resulted in significantly reduced braking ability, creating a serious risk of a crash. The vehicle had approximately 74,221 miles at the time of the incident. The dealer repair invoice documenting

Body to frame ground cables corroded in half two different times within about 6 months. First time engine wouldn’t start had to have it towed to dealer for repair, over 30 codes were shown when this happened. Next incident some of my lights were working intermittently and my steering was rendered inoperable for 20 to 30 seconds at a time making it impossible to steer the vehicle, several codes were found when this happened, I drove the truck to a Chevrolet dealer for repair. Both repairs were deemed to be corroded ground cables. Chevrolet has a “customer appreciation program” covering 2019-2024 Silverado trucks but for some reason my VIN number doesn’t land in the program even though it has the same issues that are covered for the other silverados.

Rear windows water leak. May caue electrical issues and mold in the cab

Motor blew up. 6.2 L87. 2020 silverado 90000 miles, this will be the 4th motor

Complete brake system, master cylinder, pads, rotors. Only 75000+- miles. Morning start and the brakes are locked up. Had to get towed and the entire system needed to be replaced. So after several days and almost $5,000 I started driving home. After about 5 miles something fell off the front brakes and bounced along underneath but I was close to home so I continued and didn't need to apply the brakes until my driveway and then a terrible grinding sound. Called the dealer (Modern Chevrolet) Winston-Salem NC. Turns out the Einsteins who did the work forgot to tighten the bolts holding the rotor and one fell out and the other one was grinding against the wheel. So another extended stay at the dealership to correct this, a new wheel and correction to the brake components.

Vehicle came to abrupt stop with no warning and no reason. There was not a vehicle in front of me, nor behind me when this occurred. If there had been a vehicle coming behind me there would have been a collision.

While stopped at a highway red light, the vehicle jolted forward and numerous dash lights came on, including messages saying “Brake System Failure, Service ESC, Service Trailer Brake, Service Parking Brake, Engine Power Reduced, Power Steering Reduced.” This is the first time any of these messages have ever appeared. This made the vehicle incredibly difficult to steer and the braking ability was almost non-existent. Had this happened one minute earlier or later, a multi-vehicle and potentially fatal accident would likely have occurred. Vehicle was towed to a dealer who confirmed the error messages and severely reduced performance. To me, this seems consistent with GM service bulletins PIT5730 and 20-NA-073. The dealer, however, is quoting me $3,700 to repair the master cylinder and electronic control braking module. Whatever the case, this absolutely needs to be upgraded to a recall before this happens to somebody at the wrong time.

Vehicle sent alert on phone saying battery critically low, then the vehicle started having fuel gauge issue and started lurching. Shut the vehicle down saw a P129F in the alerts. Checked battery vehicle was a no start. Luckily near a shop so it wasn't catastrophic and was able to r eplace the fuel pump control module and it instantly started. This part NEEDS to be recalled it is a safety hazard that chevy does not aknowledge

Purchased used in 02/2022. Pickup started to shutter when shifting at 35-45 MPH. Took it to Turnpike Chevy who found thrust bearing in reaction carrier broken and damaged planetary gear set. They replaced the reaction carrier ASM and Reconditioned the transmission ASM. Replaced the valve body ASM. Took to John Sauder Chevy numerous times between July 19 2024 and July 7 2025 due to the shutter when shifting having returned. They tried the GM approved fix of flashing the computer to reprogram and kept saying they could not duplicate. On June 18, 2025 while towing a trailer on the highway while going highway speeds in the middle of rush hour traffic the transmission suddenly started making a shrill noise. Transmission disengaged and lost power. John Sauder Chevrolet found a broken oil pump drive and drive gears on the 10L80E transmission. GMC refused to replace the transmission and now it is out of warranty and starting shutter again when it shifts

On July 22, 2026 took truck to dealership for oil change and reported getting random (trailer brake, power steering) service alarms. Was told it might be a ground strap issue and was sent on my way. After investigating, there is a GM service bulletin (#23-NA-201) on the issue but does not cover my truck. After a week of vacation, began driving truck again and alarms became more frequent, including loss of power steering and jerking of steering wheel while driving. Arranged with dealership to replace the ground strap (at my expense). By the time they could schedule, the alarms were constant and the truck had completely lost power steering. One of the power steering failures nearly resulted in an accident while turning.

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 p

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.
