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: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

Heard funny noise coming from vehicle. After that the cars battery would be dead. Could recharge battery but it would be dead the next day. Took it in to a private shop where it was found that the ABS module under the frame was corroded and drawing down the battery by grounding on the frame. It also destroyed a computer and two plugs on the transmission neutral safety switch. Total repairs to vehicle totaled over $2,300.

2003 Trailblazer - reduced engine power light present when started. Would accelerate to 15mph. Rattle or grinding noise when braking or driving over bumps. Drove to beaty Chevrolet knoxville tn tues, 2/7/06. Replaced throttle assembly & advised noise was from misaligned hood. Trailblazer picked up on fri, 2/10/06. Paid $200. Ext warranty ded. Gas empty stopped to fill up. While driving noticed fuel gauge past full mark, appeared to be pointing straight down. Noticed tachometer registered 6500 rpms. Called beaty Chevrolet. Service department closed. Next day fuel gauge appears correct. After a week refueled and noticed fuel gauge was incorrect again. Noticed strong gas odor when vehicle is started & vehicle smoking. Called to schedule repairs on 2/28/06. Was unable to make appointment rescheduled for tues 3/9/06. Beaty informed that it must be guage sensor and not related to previous repair work so another $200. Deductible would be due. They were unable to detect fuel odor nor smoking. I disagreed with the $200 charge due to vehicle being defective when I picked it up from the service department on the first visit. Beaty chev. Said they did not look at the tachometer nor fuel gauge when they service vehicles so they would not have known about the problem. Lol.. I called GM warranty and they would not waive the $200 and said the dealership would be responsible. I contacted the dealership again and they thought GM would waived because of the numerous problems with the guage sensors. However they would not admit that they did not check the vehicle when it was being repaired the first visit. I have read numerous complaints regarding reduced power throttle assembly, guage malfunctions, and grinding noise when braking and feel that GM should recall and reimburse the consumer for the repairs they have paid. Vehicle is still making grinding noise and now seems to lunge forward when brake is released. I need help and any advice you have to offer.

2003 Chevrolet Trailblazer developed problems with the brake pedal. The brake pedal would fade intermittently when stopping. The consumer would be at a stop light and the pedal would release and would go the floor. The brake pedal had no resistance until the pedal was significantly depressed.

When depressing the brake pedal, the brakes failed to respond to pedal application until almost touching the floorboard. Vehicle was traveling 55-60 mph when it was involved in a crash. There was a loud noise which was related to the brake dragging in the rear into the retaining wall, then to the left retaining wall of the right rear wheel and the tire suspension axle housing broke. The disk and rotor needed to be replaced, the left tire went flat. After repair the consumer heard a dragging sound and the vehicle had come to a stop. The consumer viewed a blue colored smoke along with a smell coming from the brakes. Currently when turning left or right the dragging sound is heard on the right side.
