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.

Two years ago the liftgate when closing would not lock and remote lock key fob failed to work. Dashlight indicated that tailgate was ajar and dome lights remained on. In the last year the controls on the driver' S door quit working. The power locks, windows, and side mirror controls did not work. Rear defroster will not work. No parts have been replaced because dealerships will not do it for free. I could not afford to fix this problem. Very frustrating.....first new vehicle, and it will be my one and only Chevrolet. I will no longer purchase from GM due to their lack of willingness to fix a problem that they were aware existed in many vehicles.

I live in southwest Ohio and I own a 2002 Trailblazer. I noticed that in December of 2006, my rear windshield wiper would not function when turned on. Shortly thereafter, we had our first frost and I noticed that the rear defogger/defroster was not working. It is now nearly 0 degrees outside and even if I clean the window with a scraper, it still frosts up while driving. I have looked for a fuse to replace, but find none for the rear defrost, and the one for the rear wiper is fine. Just yesterday, I picked up some large items at a home improvement store and was unable to unlock the rear gate, I tried to use the button on my remote, to which the car no longer responds, even with new battery, I tried to unlock it from the driver side controls with the car off and turned on, but nothing happened. So there me and my pregnant wife were standing in zero temperature weather with three large items on a cart and nowhere to go with them. We ended up paying somebody to haul them to our house.

Have had many of the problems I read on posted complaints: New engine required within nine months-one year of owning new vehicle, inside driver door panel replaced three times, change oil and service engine lights staying on, hood not closing properly, back glass needing replacement, fabric problems in back seat, etc., etc. And this morning it is a $200 problem with the headlight switch. Too many things to even remember or name, but Chevy has a pretty thick file on me and my vehicle.

Trailblazer 6-cyl

Upon starting vehicle, the electrical system malfunctioned, causing the headlights, radio, and the dashboard lights to short out. This happened several times. The consumer had taken the vehicle to the dealer and they changed the sensors, however it did not solve the problem. There was noise in the steering wheel. The consumer was told that the problem was a characteristic. The hatch lock did not work, and the rear windshield wiper did not work. The oxygen sensor was changed twice along with the seat belt switch, the key lock on the driver door, battery, and the wiring harness. Also the cup holder broke.

The brake lights have burned out in the last 3 mos. 3 different times. The passenger side brake light seems to go out every month. I was complaining about the passenger seat belt locking up but thought I was just doing it wrong. After reading other complaints I noticed that it is a common occurrence. I have had the trail Blazer in the shop for the noise under the front when you hit a bump. They can't seem to find the cause of the noise. The back gate would pop open just driving down the road. Dealer adjusted the latching hook. Has not done it since. Now after doing some research I have found that there are 8 recalls on this vehicle and I have just received 2 notices. This is a bit unnerving.
