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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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 #11

Dec 012007

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 15,675 miles


Failure of rear brakes due to defective metal used in brake rotors which caused rotors to become heavily rusted causing brake pads to drag on rotors destroying boy=the pads and rotors.

: the contact stated while applying brake pressure at 65 mph on the highway, the brakes pulsated, and there was an increased stopping distance. The vehicle was inspected by a dealer who determined that all four rotors were corrosive and needed to be replaced. The manufacturer was alerted.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 47,500 miles
After less than eighteen months of ownership and having not even taken a lengthy trip our ls has racked up more head aches than a little. Just a few months ago dealers wanted to charge over $600. For a repair of the "fan clutch" something that never happens to vehicles to our knowledge. I have owned GM products for many years; this will certainly be the last one! now we are faced with our dealer advising us that the vehicle needs all rotors replaced, as well as pads, parking brake, etc. How could this be? most vehicles get brake pads; this thing requires all the components be replaced due to rust! (sounds like Chevy is manufacturing a faulty vehicle) we are not going to settle for it. In fact we had recommended the product to fiends and family who bought three of them. We are going to tell everyone of the experience, as well as recommend that they get rid of them as soon as possible because of such unpredictable problems. My recommendation is all owners sue to make Chevrolet take the trucks back! we also contacted Chevrolet about the unusual rusting on the underside of the hood, especially where the hinge is located - we were promptly ignored.

Brakes started pulsating when applied. Took it to the dealer who performed a brake inspection. His explanation indicated a design flaw which causes corrosion of the rotors that in turn eats the pads. Even with an extended warranty plan at 40000 miles they still refused to treat it as warranty and quoted $600 for the rears alone. I had the front rotor turned and will have the rears done by my independent mechanic. No wonder sales are down - nobody trust the manufacturers anymore more to do the right thing, they only trust them to not lose money on a failure. Who lets them get away with this kind of conduct - we do. As soon as my gas guzzler is safe to drive again out comes the for sale sign.

4 wheel drive failure light on dash board and "4 wheel drive full" and "4 wheel drive low" light keep flashing and when I placed truck in park and shut off truck, it lunged backward. Gas tank wouldn't take gas and the last time it spit gas out and out onto pavement. Brakes don't seem to stop very well and I now have a pulsating feeling under my foot when I brake.
