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 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

Trailblazer was making roaring noise when first starting up and took about 2 minutes for it to run normal, voltage meter fluctuates as well as the lights dimming intermittently during this time. This started happening about 3 weeks ago. When first taking off after being stopped, engine accelerates unexpectedly. It jumps, and I have to hit the brakes. It has had this problem since I have owned it (since Jan '09). The last couple of days if the radio is left on, it does not automatically shut off like it is supposed to when you shut the door. The passenger side works. Just had clutch fan and water pump replaced and the mechanic says that it is a common problem with these vehicles. After having that done, it still makes a roaring noise for the first five to ten minutes of driving. Going to have another diagnostic on it to see what is wrong with it. The SUV is a 2005 Chevrolet Trailblazer ls, 4WD, 6 cylinder motor and has about 88,000 miles on it.

I have had my water pump replaced twice in that last 1.5 years. The first time was covered under warranty but the next time about 10 month the dealership claim it didn't work again. Just today 12/12 I went to drive to work after letting my car warm up for 5 minutes I decided to turn the heat on and nothing came out now I have to call and see if anyone can look my auto. Worse brand new auto that I have had.
