2025 Chevrolet Colorado Brakes Problems

“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.”

“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.

I got an error notification the day prior that said there was an electrical error and my check engine light came in. …”

“This truck was purchased May 2025 and currently has 2600 miles. Without any warning the brake light and ABS warning lights came on along with messages reading Brake Assist,ESC, and Trailer Brake require service. I took my truck in to a Chevrolet dealer on Aug 18, 2025 for inspection of issue. I was informed the Master Cylinder has failed and because this was a “SAFETY” issue I could not take drive my truck and they would not allow me to remove the vehicle from their lot.
