Filed Nov 2, 2026 · Brakes · OH

Was driving for about an hour pulling our 7,000 lb camper when all of sudden my daah lit up with all kind of lights and warnings. The messages were Service Trailer Btake System, Service ESC, Service Parking Brake, Brake System Failure 62mph top speed, check engine light, Traction Control Off, ABS Off. Pretty much had no brakes and had to use the manual gear selection to slow down from 65 mph. Not a good feeling wh no brakes pulling a camper. The brake pedal was hard and used everything I had to get it to go in to try to stop. Now my rear brakes on the truck currently making all kind of noise and the truck went to the mechanic today.

Truck has less than 30K miles with normal usage and rear axle was leaking onto the brake disk and brake pads. This could potentially have caused braking problems. The dealer noticed this problem during a routine oil change. Dirt had crusted on the leakage area and none of the fluid had leaked upon the ground and was therefore not noticed while in the garage. There was no obvious external warning that this issue existed. Have currently scheduled a repair with the dealer, which includes new brake pads and disk resurfacing.

It said on the dash, "Brake System Failure 43MPH Top Speed," "Service ESC," and lights on were the ABS light, BRAKE light, Engine Light, and Wheel Traction light. My wife and my [XXX] son's safety were at risk while driving on a busy 75mph highway and trying to turn around and make it home as the brakes did not work and having to cross busy streets. It was not able to reproduce but my local mechanic found the bulletin from way back that had not been addressed by GM after numerous times to a dealer for other repairs. I then took it to a local GM dealer that confirmed software update was not applied and they did the repair and I was charged to pay even though this was a known GM issue that never contacted me about this potential fatal random occurrence that could happen after I have taken great care of this truck. There not any warnings before randomly losing power on the highway once she hit 60mph on the on ramp and just started failing slowly.

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.

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.

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.

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.

I went to the store and my brakes were working as normal. When I started my truck to leave I had a hard pedal and there we several warnings on the dash. One said to get service and the other said to limit speed to 43 MPH. I had almost no braking power. Fortunately, I was close to home and the speed limit was 30 MPH all the way home. Once I arrived home I cleared the code with my ODBII scanner and the brakes worked as expected. If I was towing my boat this could have been a bad situation resulting in an accident. I haven't had the same issue in several days however this has to be a huge liability for GM. I'm sure that this is a known failure mode for GM.

The Electronic Parking Brake System on my 2020 Chevy Silverado 1500 continuously malfunctions. Chevy/ GM Customer Support has been made aware of this issue and continues to disregard it entirely. The Electronic Parking Brake, which is an automatic function that cannot be turned off or bypassed, fails to fully disengage when the vehicle is taken out of Park. The Electronic Parking Brake remains very slightly engaged, producing a slight noise while driving and causing excessively premature wear on the vehicles pads and rotors. My vehicle has about 64,000 miles on it, and I have had to replace my rear brakes twice now already, due to this issue. The majority of those 64,000 miles are from uninterrupted highway driving. Each time the rear brakes were replaced, I had the dealership inspect the braking system. The dealership was not able to definitively confirm for some reason but was able to speculate that the aforementioned is likely what is going on. I find that any malfunction of such a critical part of the vehicle and the safety of it's operators and passengers poses a major safety risk.
