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.

Takata recall I was involved in an accident that did over $9,000 damage to my front end of vehicle. The airbags did not inflate. This was on a city street, and both vehicles were moving. Also had a power window motor go out. I understand that this might be involved in a recall of window motors that could be causing fires.

All interior and exterior lights flash every second when engine RPM at 2000 and above. Radio occasionally has noise that changes with engine RPM, also stepping on brake pedal causes clicking noise over speakers when radio is playing. Service charging system warning on driver's console when temperature 80 degrees and above. Flashing started after Chevy dealer replaced the underhood bussed electric center (ubec) which was suppose to resolve the service charging system warning and transmission interlock solenoid failing to let truck out of park.

Bad blower motor resistor. The A/C completely shuts off when switched to position "5" on fan speed. I just replaced this part about a month ago. It has been working fine since I replaced it. The same thing is happening again now. The fan shuts completely off when in position "5". this needs to be recalled. There is something wrong with the design of the electrical system. I am worried that this will eventually cause a fire from malfunctioning. Yet another problem with this vehicle.

At a red light and attempted to close the driver's side electric window. When I pressed the buttom to raise the window the window stopped raising to a closed position and heard a loud noise similar to glass crumbling inside driver door. Is the regulator covered under a recall. I previously had the driver's door master power window switch module replaced due to a recall. I have always had problems with the driver's side window mechanism always slowing down and stopping midway during cold temperatures.

The ignition will not turn off unless the bright lights are on. At times, it will start automatically even when the ignition switch is turned off. Sometimes the ignition will not turn on or off at all. Fuel system is faulty. Consistently problems have caused the fuel pump to go out repeatedly, and the fuel gauge to stop working. Motor in the drivers seat stopped working after months of problems. The radio has stopped working. We've replaced the fuse, and have been told its an electrical problem.
