Print this page 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.

I have an excessive amount of wind noise around the front windows especially at speeds over 50. I have checked with my dealer, but there appear to be no fixes. I contacted GM but they said they have no complaints and offered no help except to check with my dealer. I tried out a few other Trailblazers and found the same wind noise issue. I saw similar complaints on other web sites, but none are making it here. It appears turning up the radio may be the only fix.

I have had nothing but problems with my 06 Trailblazer. The front windows rattle horribly, there is a film that is all over the windows all the time, the passenger door speaker has been replaced going on 4 times now, the power points have been replaced, also the stabilizer (which I do not think are fixed) and now they are replacing the stereo in it. They tell me the problem with the windows is "it's how they are made and they all rattle", power points..."don't use them"...speakers..."turn the music down"...stabilizers I have given up on. And now there is a smell like something is burning in the car. It does not happen all the time, so there is no way to point it out. This is the first for the stereo. I can not drive with the windows down..they even rattle when up!

: the contact stated while the vehicle was parked on an incline, the rainwater did not drain properly and went backward into the passenger side of the vehicle. This caused the passenger side floor board to flood. The dealership determined this was how the vehicle was manufactured and should not be parked on an incline.
