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.

overheating overheating

My wife, I have purchased a 2006 Chevy Trailblazer on the 28th of February, AS IS. Not even a week, the check engine light came on. I took the SUV to Autozone. They gave me a print out showing what was wrong. I call the place that my wife and I got the SUV. I was told to bring the SUV there. He stated that what was stated on the print out was done, but that was only the one thing out of four. The replaced part was, is the coolant sensor. That was suppose to be fixed but the SUV has been getting hot, overheating but the heat came on. The fan that is in front of the water pump is lose, the nuts are not tight. My wife was told that there nothing that can be done. One reason is that you have the SUV over 90 days, it's on you to get fixed but the SUV has not been with us 90 days because we bought it on the 28th of February and May 28th will be 90 days.
