I am reporting two brake-system failures involving my 2025 Chevrolet Colorado. Both involved brake-fluid leakage from the left-rear brake caliper, including a recurrence after that caliper had already been replaced under warranty. On May 27, 2026, after the truck had just been driven home, we loaded it for a camping trip with our granddaughter. When we started the vehicle to leave, multiple warning lights appeared and the truck had very little braking capability. The Chevrolet dealer documented DTC C05B0 and found that the driver's-side rear brake caliper had separated and was leaking brake fluid from the actuator side. The dealer replaced the left-rear caliper (GM part #13537065), added brake fluid, bled the system, and road-tested the vehicle. On October 19, 2026, approximately five months later, the truck displayed a "Service Parking Brake" warning. The dealer documented DTCs C060B and C2A21 and found brake fluid leaking through the left-rear caliper into the parking-brake actuator. The dealer again replaced the left-rear caliper with the same GM part #13537065 and also replaced the affected parking-brake actuator (GM part #13513581). I am concerned because the replacement caliper experienced another brake-fluid leak only five months after the first failure. The first incident resulted in very little braking capability, and we were fortunate it became apparent in our driveway rather than while driving. I am reporting this because of the serious safety risk of recurring brake-fluid leakage and diminished braking. I am aware NHTSA is investigating brake issues involving Chevrolet Colorado vehicles. I do not know whether these failures are related and am providing the dealer findings, DTCs and part numbers so NHTSA can make that determination.

The contact's husband owns a 2025 Chevrolet Colorado. The contact stated that after exiting a car wash tunnel and parking the vehicle on the side of the car wash building, the vehicle continued to roll forward at a high speed without warning. The contact used both feet and excessive force on the brake pedal to stop the vehicle; however, the vehicle continued to roll forward. The vehicle ran over the parking pillar and crashed into a brick column attached to the building. The vehicle continued to roll forward after the crash and eventually stopped once it rolled over the car wash road indentation. The contact reversed out of the car wash indentation and called her husband for assistance. After her husband arrived at the scene; the vehicle was driven to the residence without any further issues. The vehicle remained at the residence and was not yet diagnosed or repaired. The manufacturer was notified of the failure, and the contact was provided a case number. The failure mileage was approximately 111,817.
At 6700 miles, the following warning lights came on: Service Trailer Brake Service ESC Service Brake Assist Adaptive Cruise control unavailable. I brought the truck to the dealer. They read the codes and found a service bulletin. “6721 found service bulletin for code C055F vehicle needs a master cylinder/booster/ebcm parts ordered” They told me it was safe to drive but I refused to drive given what I found online about this issues. The vehicle took a week to fix.
