Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

problem #8

Trailblazer 4WD 6-cyl

  • 79,000 miles


Purchased this vehicle from a dealer. The next day the truck was dead. It has since had the battery replaced 3 times. The exhaust manifold cracked at 82,000. The number 4 position on the blower does not work. The stabiltrak lights come on for no reason and go off for no reason. With all of the complaints, something should be done.

The contact owns a 2008 Chevrolet Trailblazer. The contact stated that while operating the vehicle, the traction control and the low air pressure sensor lights illuminated. After inspecting the vehicle, the contact discovered that the failure occurred although the air pressure in the tires was normal and the vehicle was not experiencing a traction control issue. The vehicle was not diagnosed or repaired and the manufacturer was notified of the failure. The failure mileage was 95,000. Updated 4/16/15

Vehicles stabilitrac light comes on constantly. Repair listed for code is not the problem. Had same issue with my 2006 Trailblazer. Light comes on sporadically, even when backing out of my driveway at low rate of speed.

Stabilitrak lights on dash come on as I am leaving my driveway in the mornings and when I leave work in the evenings. This occurs when the steering wheel is turned to the right. They usually go off after stopping and restarting the vehicle. Sometimes they come on again within minutes. This problem is becoming more frequent and the lights are coming on and staying on more frequently. When I got my transmission serviced last week the mechanic pulled the code on it and it showed to be the steering wheel angle position sensor. I have found multiple instances of this same problem in automotive forums via google and it seems to be a common problem in this year model.

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).

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.

While driving multiple times reaching a right hand curve at highway speeds the electronic stability control light flashes and the anti-lock brakes simultaneously engage multiple times sometimes bad enough to cause a wheel to slip. Dealer has been in touch multiple times with GM about the problem and claim they cant figure out what's wrong. Happens multiple times per week.
