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.

First time I've had a valve head break on any vehicle I've owned. Got this vehicle at public surplus auction, ran great for a few months then BAM! Sounds like a damn Harley. Mechanic inspected and found the valve head sitting on top of piston 3, cylinder walls trashed, piston damaged, used engine $2.5-$3K installed. Pretty difficult engine swap because the differential bolts to the oil pan and then the front driveshaft runs through the pan itself. Haven't done anything with it since. Bummer too, the interior and exterior are in great shape. Any compensation from GM on this one? I know, too many miles. FML!
