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.

While driving at night, the low beam headlights stopped working without notice. Stopped at next convenience store, checked all fuses and all were good. Started ignition and lights still did not work. Checked high beam headlights and they worked. Followed up with mechanic the following morning. Could not diagnose problem and referred to a local dealer. Dealer diagnosed problem as being a faulty BCM. BCM was replaced. Approx. 8 weeks later, same problem w/low beam lights not working. Dealer replaced relay. Now low beams work, check engine light has come on and fuel gauge has stopped working.
