WHEELS, SERVICE BRAKES, VEHICLE SPEED CONTROL
1) The vehicle experienced a rear axle/rear-wheel lock-up after the recall-related repair was performed and the same diagnostic codes associated with the initial repair reportedly returned. 2)The rear axle/rear wheels locked while the vehicle was being driven on the highway, creating a significant loss-of-control and collision hazard. A sudden drivetrain/axle lock-up at highway speed causes the vehicle to stop or behave unpredictably, potentially resulting in a severe collision 3) Yes. Huffines Chevrolet performed the initial recall-related repair and subsequently the same diagnostic codes reportedly returned after said repair 4) The vehicle has been inspected by 2 Chevrolet dealerships, including Huffines Chevrolet and El Dorado Chevrolet/Motors. The matter has also been reported to GM Customer Assistance under Case No. 110236243 5) Yes. Diagnostic codes associated with the recall-related issue were present when the vehicle was initially taken to Huffines Chevrolet on August 10, 2026. Huffines performed recall-related repairs, including replacement of the transmission module as part of the attempted repair. After the vehicle was returned, the problem recurred. On August 28, 2026, while driving on the highway, the rear axle/rear wheels locked, and the same diagnostic codes reportedly returned.

POWER TRAIN
While driving on the highway our transmission cooling line completely separated at rubber hose to metal line crimp. This cause transmission fluid to burst out all over the vehicle including the windshield and trailer. Vehicle immediately stopped pulling and we barely were able to get to the side of the road. This also caused a catastrophic transmission failure costing approximately $10,000 to repair. GM covered some of the transmission cost but still left us with $5000 bill for a transmission line defect on a vehicle under 100,000 miles. This created a unsafe condition with the trans fluid on the windshield and immediate loss of drive. All maintenance was performed per manufacturers specifications and no warning signs/lights/leaks provided prior to the failure. I do have pictures of the failed transmission cooling line.

STEERING, ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
My vehicle was taken to Legacy Chevrolet of Waxahachie where a routine recall notice was addressed. During the process they technician broke my battery terminal. Upon my discovery the dealership claimed the broken terminal must have just broke on its own during the time it was at their dealership in spite of the ECM module update requiring the technician to specifically remove the battery cable from that specific terminal. Legacy has refused to address this issue and charged me for the new batteries as well as for the tow that was required. The damage was caused by their technician and all of the costs incurred should have been absorbed by the dealership.

ELECTRICAL SYSTEM
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.

POWER TRAIN
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.

SERVICE BRAKES
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 the codes and repair is available upon request.

STEERING, ELECTRICAL SYSTEM, EXTERIOR LIGHTING
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.

SERVICE BRAKES
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.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

FUEL/PROPULSION SYSTEM
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
