NHTSA Complaint #11688764 — 2025 CHEVROLET COLORADO

On the day of purchase, while driving on a freeway, the vehicle would not accelerate. The RPM's went up, the engine revved, but the vehicle acted as if it was in neutral. These vehicles will not accelerate if they think the brake pedal is also being pressed. The brake was not being depressed. As I was pulling the vehicle to the side of the road, suddenly it allowed me to accelerate again, and I continued with no further issues. One week later, with fewer than 200 miles on the vehicle, upon starting the dashboard showed alerts to Service ESC, Service Brake Assist, Service Trailer Brake System. The ABS and Traction Control lights also came on. These are all systems designed to prevent loss of control, and all failed without warning. A dealer service center diagnosed this as a known problem with a faulty master cylinder, on several models built over a period of several months.
