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.

The gas gauge is inaccurate. I ran out of gas when I thought there was gas in the car. Since then (had just recently purchased vehicle) I have to fill up and reset mileage so that I will know if I actually have gas and when it is likely that I'll need to get more.

Fuel gauge inoperable just as stated in all the other complaints. Chevy should be held accountable to repair at no cost for the life of the vehicle. Please mandate a recall as soon as possible.

Check engine light come one code P0461 - fuel tank pressure sensor circuit high voltage. This problem seems to be a common problem with the Chevy Trailblazers and should be a recallable issue. Furthermore, the suspension on this vehicle has been a financial drain from the sway bar links, front end links stabilizer shaft and ball joints.

Gas gauge fluctuates, filled gas tank, moments later it went down to empty (warning light and sound went off). This has happened for the past week. Prior to this the check engine would sporadically go off and on, probably an early indicator that there was a problem with the fuel gauge. Problem has caused my family to be stranded on the freeway at night while I am at work and I have to go help them this is a big safety issue. GM only wants to pay for part of the repair, which is not right as the issue is wide spread and is a safety issue.
