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.

CarComplaints.com 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.

Trailblazer 4WD 6-cyl

Purchased Feb 1, 2002. Since then have had nothing but problems. Had into 4 different dearlerships fixing many problems but after each visit another problem occurs. From tail lights burning out, windhshield wiper motor failures, instrument cluster replaced, heater control panel replaced once, memory mirror modules replaced 2 times, heated seat switches replaced 2 times, rear window defogger/replaced entire rear window 1 time, battery replaced 1 time ( said battery was at fault for current problems) battery was fine and charged me $ 150 for new battery that was not the correct battery replacement, exhaust gasket became loose/loud and had to be replaced, the fuel pump replaced because it just cut off as I was on the expressway going approx 65 miles an hour, I had to get to the side of the road quickly- had to be towed to dealership. Problem fixed, however after I picked it up then the current problem began. I could go on and on with the problems that I have had. Present problem is that whenever I turn on the heat it dies out with no warning---just stops and stalls. Dealership says they fixd it but upon pick up the problem still exists. Gone to pick it up 2 times, but when I start it and put on heat, it dies all over again even after dealership claims they fixed it. I live in Chicago and it has been a cold winter. Almost caused a crash on another expressway on way home from having the airbag sensor and a complete brake job done and all fluids changed. This vehicle is not worth $ 37,000 and I feel it is time that GM accept some responsibility for this lemon of a vehicle. It is my only vehicle and I am still paying dearly for it but lately cannot even use it as it remains in one dealership after another at my expense. I will not purchase another vehicle from GM. I need help and answers as I am not getting anywhere even with this vehicle still under warranty.

I bought my Trailblazer on April, 2002. Since then, I have had only electrical problems. The indicator light above the four-wheel drive knob has failed twice. The dome light has failed twice. The driver's side reverse light has failed once. Finally, the passenger-side brake light just recently failed. All but the brake light has been serviced by the dealership which sold me the Trailblazer. From the repair description, the problem did not lie from a burned-out bulb. Rather, the problem stemmed from a fuse or another internal, electrical problem.
