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.

I own a 2002 Chevy Trailblazer. There have been numerous problems dealing with bulbs. The main issue I'm having now is the fan clutch. My engine revs really high when I'm driving. The cost of the repair is well over $900. I believe this should qualify as a recall. I've researched various message boards & find this to be a common problem with Trailblazer owners.

I brought this SUV from the dealership and I started having problems with it a month after I brought it. The car air conditioner stop working and the transmission was making a horrible sound. I took the car to the dealer to get fixed three times. All the times I took the car it came back the same way that I took at first. I also took it to a different dealer to get fixed and they also didn't fixed it. I want to cancel this SUV purchase. Mainly because even before T brought the SUV the salesperson at the dealer added $5,000 to my income so I could qualify to get the SUV, but that was completely a lie. Right now I'm having many problems at work; that's the main reason I want to cancel the purchase of this SUV, which is just giving me many problems.

There is a very strong odor of fuel from the exhaust. After GM campaign 03012 and 03012, denley code 07222 was performed, that was when the odor was present.

Electronic exterior rearview mirrors and power seat engage and operate by themselves. Dealership cannot fix the problem. The memory for the mirrors and seat would not keep their position. When the consumer entered or exited the vehicle the systems would reset to a new position. Occasionally they moved while the vehicle was in motion. The dealer has replaced many components but the problem still exist. The check engine light illuminated. The dealer replaced the oxygen sensor. The A/C control mode button became stuck and was noisy. The dealer replaced the A/C module head. The left windshield wiper chattered and skipped. The dealer replaced the wiper insert. The 4WD switch fluctuated between 4wh and A4wh. The dealer inspected the vehicle and replaced the transfer case select switch.

The rear window of my 2002 Chevrolet Trailblazer pops open while driving, even when it is locked. Its been into the dealer (3 different ones) 7 times and Chevrolet has told me that since they can't replicate the problem, there is nothing they can do. The window pops open several times a week. We do drive on a dirt road, but its nothing unusually rough. My wife has started having migraine headaches, and they started a few weeks after we bought this car. We have the opinion of several doctors that say these headaches could be caused by the exhaust that fills the car when the window pops open. I've asked the dealer if they could make the window so it doesn't open at all, but since its a lease, they won't do anything to the car that would affect the value of the car. I also believe this to be a problem because of what could happen when I'm driving down the interstate and the window pops open (which happens very often) and something flies out the window and causes another car to wreck and possibly kills someone. Another problem I have is that sometimes the window unlatches, and we don't realize it. If I park my vehicle somewhere and someone steals the contents of the car, or the car itself. After discussing these issues with the Chevrolet customer service rep (dan) they said they are not responsible for any of these cases. This failure happens about every three days and started about a week after we bought it (around 7/5/2002). We've had 3 other new leased vehicles (1998 Dodge Ram, 2000 Pontiac Grand Am, and a 2001 Dodge Ram) since moving into our current house and have had absolutely no problems that have been caused by the roads we drive on, or how we drive them. I fear for my safety as well as the safety of others while driving this car, however I don't have a choice since I can't afford to terminate the lease and buy another car.....please help.
