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.

My wife was driving on the freeway and vehicle just shut down. How dangerous is that? Vehicle cranks but does not start initially make pinging type noise which leads to lack of fuel. A engine light came on separate from the check engine light, the owners manual says this light is for the Electronic Throttle Control malfunction. the light looks like a picture of the engine with an arrow pointing down. I ran a code scan and got a code p1516 meaning Commanded vs Actual TP Performance (TAC Module) I replaced the acceleration module on the pedal and it did nothing . Is it a recall?
