Print this page 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 a brand new 2006 Chevy Trailblazer in Jan. 19, 2006. On Jan. 20, 2009 the 4-wheel drive component in the Trailblazer quit working. Now I am over the 36,000 miles - I have approx. 44, 000 miles on the Trailblazer. The 4 wheel-drive will not work in 4WD hi, 4WD lo or automatic 4WD. I live in northwestern pa and need 4WD, especially the winter of 2009. There have been numerous occasions that I have slid on the road narrowly missing an accident due to not having 4 wheel drive. I called several dealers and asked if they had problems but was told one of two answers: 1. that's what happens when you buy a 4 wheel drive vehicle or 2. there's nothing we can do about it. I have never heard of this problem with any other model on such low mileage!
