Trailblazer 6-cyl

  • 101,985 miles


While turning around in a cul de sac one morning that was on a steep slope I heard a popping sound and my steering wheel jerked and the brake pedal depressed almost to the floor in three stages like it was catching on something and then would release and the stability control lights came on. Once I got the vehicle straightened out to go down the steep hill it felt like it does when a rotor gets warped. Once I got close to the bottom I turned onto a side street that was flat and I stopped and put it in park and turned the engine off. When I started it back up the lights were off and the brakes and steering returned to normal. The lights coming on has been a problem since I purchased the vehicle (listed in another complaint to follow).

Trailblazer 6-cyl

  • 56,000 miles
While driving the 2008 Trailblazer I started to experience a loss of brake pedal with the travel going all of the way to the floor, with hardly any braking function or stopping action. It was intermittent and would not happen more then once or twice at first. Then when I was in a parking lot, the brakes failed again and I hit a cement divider damaging the bumper of the vehicle. You would be driving the vehicle, and step on the brakes as you would be coasting into or coming up to a stop. You would let up on the pedal then hit it again, the 2nd time loosing all brake pressure and function. I had to take the vehicle into the GM dealership for service. There were no fluid leaks, or any type of brake rotor damage. The dealership came back saying that the master cylinder had failed on the vehicle. This is on a Chevrolet truck, 4X4 that is supposed to be heavy duty off road capable package. General Motors would not cover the repair under any type of warranty claim. The repair cost me close to $800, and loss of vehicle use, along with the bumper damage. I have owned over a dozen General Motors vehicles to date over a 30 year period. I have never, ever had a master cylinder fail on any of them. This is a poor quality controlled component and I want G.M. to compensate me for the repairs and damages. I have raised this issue through the General Motors customer service line, and they refuse to cover the repairs.

The contact owns a 2008 Chevrolet Trailblazer. While driving at 25 mph, the stability track warning light illuminated on the instrumental panel. The warning light illuminated twice. The dealer advised that the rack and pinion would need to be replaced, as well as the air bag sensors. The vehicle was repaired under factory warranty. In addition, the contact stated when applying the brakes, the brakes would feel abnormally soft and spongy. The dealer replaced the brake booster six times yet the failure persisted. The failure mileage was 5,012 and the current mileage was 16,000.

I have a 2008 Chevy Trailblazer ss with 13800 miles on it. I was driving in normal traffic conditions on city streets when my brakes applied them selves and began to cause the vehicle to slow down to a stop while driving. I had to press on the gas pedal heavily so the vehicle would move to avoid a collision with vehicles turning ahead of me and also vehicles traveling behind me. I got to a safe area and pulled over and saw that the gas pedal was firm as can be and would not loosen up, I shifted the vehicle into park and the brakes disengaged. I took the vehicle to the dealer the next day and they where un able to replicate the problem and returned the vehicle to me with no repairs completed. I asked them to document this in case it happens again and causes a crash so they can be held liable. I do not feel safe operating my vehicle anymore knowing that at any time my brakes might turn on.

The contact owns a 2008 Chevrolet Trailblazer. When the contact attempted to accelerate at a traffic light, the brakes would not disengage. He attempted to release the brakes by shifting gears and apply constant, steady pressure to the brake pedal. Within a few minutes, the brake released. On a separate occasion, while driving at speeds of 15 mph, the brakes locked. He abruptly depressed the accelerator pedal in an attempt to avoid a potential crash. He was able to maneuver the vehicle off of the road and shut off the engine. Upon restarting the vehicle, it functioned normally. The warning lights illuminated during both failures. The dealer could not duplicate nor determine the cause of the failure. There were no repairs made to the vehicle. The manufacturer was not notified. The current mileage was 31,225 and the failure mileage was approximately 24,000.

I was stopped for a red light on a slight hill. When it turned green I tried to move ahead and all 4 brakes had locked up and I had no forward motion. I pushed had on gas pedal and was able to creep at about 1 mph to a driveway. When I entered driveway I heard a "clink" and brakes released.this veh has 5200 miles and is a 2008 Trailblazer ss AWD. This is the 1st instance of this type.I took it to my servicing Chevy dealer and they checked it out and said that "mechanically " it was fine. They contacted Chevrolet tac and were told this has never ever happened in the whole data base for GM and no repairs authorized till it can be replicated for them to see. There were no codes stored. This happened 0N 4-25-09. I went back to dealership on 4-28-09 and the again called tac to see if there was anyone who had info on this type of failure of the brakes....but again no luck. I feel strongly that this is a safety issue and Chevrolet should be doing more than lip service....
