Print this page Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

2002 Chevrolet Trailblazer Owner Comments

problem #4

Feb 032003

Trailblazer 6-cyl

  • Automatic transmission
  • 15,300 miles


In my 2002 Chevrolet Trailblazer, at approximately five mph, approaching a stop sign, the brake pedal went all the way to the floor and after slowing down to approximately one mph, the vehicle continued to roll thru the stop sign, across 4 lanes of traffic and finally came to a stop when it hit the curb on the opposite side of the intersection. The vehicle was subsequently hit by a large truck. There were no injuries. Had it not been for the curb, the vehicle would not have stopped. After having the vehicle towed to the nearest Chevy service facility, the service manager told me that this was an inherent behavior with anti-lock brake systems. I tend to agree with him as my 2000 Chevy Silverado had demonstrated the same behavior. There were no apparent leaks in the system and the master cyclinder was full. After the accident, the vehicle was started and the brake pedal continued to go all the way to the floor while the vehicle was in park. The service facility was not able to reproduce the behavior the next morning and referred me to GM customer service where a case has been filed.
