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.

The blower will not blow on but 3 and 4. The passenger heating is totally out. Heat out in the rear. Blower completely stops and comes back on later.

Bought this vehicle used.

Went to turn on AC and it is blowing just air. Not cold air not warm air just tepid air! AC/heat has NEVER worked on #5. Why I don't know. Wish I did. All these complaints here and nothing done about a recall. This is a shame. This is my husbands vehicle. I NEVER buy Chevy. I always buy Honda.

This proves Chevy sucks! He had a Chevy Silverado and had nothing but problems! Why can't they get it right?
