CarComplaints.com Notes: The 2005-2007 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.

What the hell ! Oh, no you mean you want to charge me over $ 450.00 to hope to fix this problem . Mr Goodwrench cant provide a definitive diagnosis or prognosis but if I buy the replacement part ( the entire headlamp assembly ) at the dealership at an inflated price.next time I come in because with this vehicle its a given they will replace the part again and again and again ..... etc .

Okay so here goes another Trailblazer complaint. My front headlight kept burning out(literally) so I take it to the shop for repair and after removing my bumper and grill to access my head light they discover that the wires have melted together from a small electrical fire. I had to replace the wires and headlight costing me $100.00. Thank God the rest of my vehicle didn't catch fire.

Headlight won't work--even with a new bulb. Police stop you for only having one headlight. This is the third wiring problem. Dealership should fix this problem for free. No way am I responsible for wiring defects in this vehicle.
