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.

Stupid electronics!!! Chevy knows about the issues with their fuel sensor and won't offer recall. Now I have to drop the entire tank, or take to a shop and pony up $450+. SUCKS!!!

My engine light keeps coming on. I have OnStar and had them do diagnostic test to see what the problem was. I took it to mechanic and they diagnose the same problem. Codes were P0128 and P00017. Had the car repair and P00017 keep come back on. I replaced the Kam shaft actuator. I am so tired of the problem I cant get my car smog. How do I get Chev to fix my car. I am not only one who has had this problem. I google it and read and find this to be a big issue.

Trailblazer LS V6

  • Automatic transmission

Still owe $10k on vehicle with regular maintenance checks and oil changes, etc to keep it running. Drove one day on highway - check engine light kept blinking but all gauges were fine and no unusual noises. Exited and immediately felt car slugging terribly. Immediately pulled into gas station to eventually learn that a valve (or valve spring) broke off and fell into a piston ruining the engine.

Two separate mechanics agreed that this was highly unusual and a fluke. GREAT NEWS FOR ME! Was told only solution is to buy a new engine. REALLY? Why can't they rebuild my engine?

I'm screwed - no warranty - no money and 3 kids with 2 in college and of course a deadbeat dad who has paid $400 since 2000 in child support.

Any recommendations? Thanks!!!
