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.

Every freakin 6 months I have to replace the headlights. I have even had to replace the plug in for headlight on the passenger side as it had melted. I had just replaced a burnt out headlight and the new one burnt out less than a day later, that's when I found the melted plug in. I should own stock in GE.

I had to replace the light on this vehicle several times. they go in and out as they please! just about every 60 days i have to replace the light bulbs in this vehicle. It started out by turning off on their on while I was driving at night. VERY DANGEROUS! I had to drive with the high beam light on in order to get to work at night! After that was fixed now the lights bulbs go out every few months! It is a Pain in the ASS to not be able to rely on you're vehicle, specially if its taking you to work and exposing you're life to danger! Chevy ya'll need to recall this vehicle or do something about this problem!

HEADLIGHTS DO NOT LAST ANYTIME IN THESE VEHICLES, ALL THE TIME REPLACING THEM WHERE THEY BURN OUT. ONE SIDE THEN THE OTHER BUT MOSTLY ON THE RIGHT SIDE.

Only one of the lights continue to go out. All work but one. It has been replaced several times and goes out the next day. I have been pulled over and received tickets. I am so tired of switching the bulb and having it burn out in 24 hours that I just drive with one light and my fogs on.

Most of the time all I have to do is hit it and it will come on and then eventually it'll go out. I change it and within 2 weeks the other side will go out. I am changing the bulbs at least 3 to 4 times a year. These bulbs are not cheap. I don't even change the bulbs in my house that often!

Trail blazer have so many electrical problems. I have 3 chevy trucks and 2 of them have electrical problems that are expensive to fix. The trail blazer's tail lights don't work. I have to check the fuse box & the wires and everything looks good. I have another chevy with the same problem. what a pain.

I have no brake lights what so ever. Stopped at a Auto parts place and they say its the electrical system, not the lights. They also said new panels cost couple hundred $$$ and they problem aren't warranty either. I am going to try calling and asking, but my problem is I would have to drive at least 75 miles to get to a dealer being none around us anymore, and the problem wont be able to fix it right away. So I will buy out of pocket skip the warranty and deal. BUT HEY WE KNOW OWN 60% OF CHEVY. just not the benefits of getting something repaired.
