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.

Have a 2002 Chevy Trailblazer- son was driving vehicle in Wyoming 20 below zero loud clunk and then grinding noise and he stopped there was no 2nd or 4th gears and no reverse. Luckily someone stopped to help him and he was ok. My car only had 51,000 miles on it. I called dealership they took it in warranty was gone repairs cost $3,420. I started researching complaints about the transmissions and realized there are over 82 complaints and that GM has known about this faulty part called a sunshell that's weak metal and the tork in the engine of the V6 cant handle the pressure so it eventually cracks and breaks then you dead in the water. This could have been a real safety hazard and for many I have read about their problems with children in the car its amazing no one have been killed yet. GM refused to have a recall on this problem due to the expense and is passing this down to its consumers to bear the burden. Will I purchase another GM car? not on your life! to anyone who has this vehicle check out the transmission problems on line and contact GM if yours goes out maybe they will step to the plate and help people who paid 32,000 for one of their vehicles!

Trailblazer 4-cyl

  • Automatic transmission
  • 100,000 miles
I recently purchased a 2002 Chevy Trailblazer, and it's about 86,000 miles on it. At about 100,000 my transmission went. I did some research, and found out that there were many people who owned this same vehicle who had the same exact problem. I also learned that this piece that is used in the transmission called the sun shield has been the problem for a lot of people. The transmission specialist that fixed my vehicle told me that this sun shield is a faulty, and a lot of GM, and Chevy owners have problems with it. There is a huge amount of people out there that are having this same problem with the same 2002 Chevy Trailblazer. I was driving on the highway, and suddenly felt that something was wrong. I am just happy that I pulled over when I did, because there was a lot of traffic that day. I was very scared, because I was alone in this car, and also I did not want to be hit from behind when I was pulling over to the shoulder of the highway. I called the GM dealer, and they said that they could do nothing for me. Even when I explained to them what had happended, and that this had happened to a lot of other people. I was told that my car was not under warranty, and this was not one of the many recalls that this truck has. I then had to fix this truck myself, and it cost me 2,300. The sun shield was replaced by something called the beast which I was told would be very very durable unlike the GM sun shield part.
