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.

After returning home from shopping, my wife and her friend pulled into our driveway and she placed our Trailblazer in park. There was a loud sound she said sounded like an explosion and the rear lift hatch window shattered sending glass flying. At the time of the glass shattering the outside temperature was close to 30 degrees. The rear defroster was not on. I came home from work and we cleaned all the glass from the driveway and the interior of the vehicle. There was no explanation as to why this happened. I contacted the insurance company and the window was fixed for a cost of $754.70 by safelite glass repair. I looked on the internet and did a search of similar incidents and found quite a few. I contacted GM by E-mail and told them what happened. GM thanked me for the information but did not offer any replacement or reimbursement. Fortunately no one was injured and our granddaughter was not in her car seat at the time. This could have been very dangerous if my wife would have been opening the lift gate when the glass shattered. GM said this appeared to be an isolated incident and I offered to send them links to other identical complaints that I found. I would like the NHTSA to please look into this as this does not seem to be an isolated incident and there was no warning of this failure. The glass was in excellent condition prior to this happening and the vehicle has never been in an accident and is in excellent condition.

The oil level indicator in the dash panel is no longer functioning. A call to the dealer where car was purchased confirms that this is part of an "instrument cluster" that also controls the speedometer, and that it will probably malfunction as well.

My head liner has fallen down 4 times and never been replace, just reglued or re velcroed, and the noises that come from my windows are quite loud and if windy the front passenger window gives a whistle, this was not the case when I purchased the vehicle but has gotten progressively worse and I am told it is normal wind noise(including the whistle that they were able to duplicate) and nothing can be done, my carpet under the mat in the drivers seat ripped (after 6 mos old) and the numbers on my radio 1-6, except 4, and the band button has started to rub off after about 6 mos old which I was again told was normal and it's because I change stations often. Incident date to follow was last date repaired.
