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.

My 2005 Trailblazer with only 28,000 miles started whining loudly, the lights flicker & the heater turns itself on. A repair shop said it may need a new alternator. Of course, Chevy only put a 3 year warranty on it & this all started happening 1 month after the warranty expired.

When I brought this car it started to give me problems. What type of problems you ask problems with the motor and injections. I called many times to the dealership I talked to a guy named henry palacios and he never gave me a solution to my problem. I had full cover on my vehicle but they told me that it didn't cover the problems that my car had. The same date that I brought the vehicle I went out of town and the car completely stop in the middle of the street.

My Chevy Trailblazer 2005 has been giving me problems not much after of leasing the SUV on 3/25/05. Not sure what day was when I got into the accident in August but it was cause do to the brakes. When backing up, I hit into my brother's truck and I couldn't stop so I kept on smashing more into my brother's truck. Not lately I am having eletrical problems too. My engine light comes on and when it does the whole SUV shakes badly. Don't understand why all of these problems are happening. I just want to get out of this lease and live!
