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.

I bought an 05 Trailblazer ext I have had it 9 months, I went to start it and it would not turn over nothing, it was also stuck in the park position, dealership said I had a bad battery, I had it checked through auto zone was fine, had it towed the tow truck driver got it out of park and was able to start it. The dealership proceeded to say it was the battery so they changed it. I picked it up brought it home and parked in the driveway like before. The next morning it would not start again had it towed to the dealership with it stuck in park again, they now have said that the ignition switch was bad, which would cause it not to start and be stuck in park, so I guess we will see if it is fixed or if it will go back for the third time in one week.

For no reason the vehicle shuts down. The vehicle has been taken to the dealer four times for this problem.
