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.

dim lights go out and won't come back on

I have been really pleased with this vehicle other than this problem with the lights. I have a great concern with the dim lights going off when I am driving at night. I can use the brights but that is a hazard to other drivers. The problem is unidentifiable at this point...can't seem to pinpoint what is causing this. It seems to be OK then all of a sudden...you have no dim lights.

Still no fix on the headlight recall problem. Lower beam headlight will burn out or whatever, replace it and three or four months later, if your lucky that it lasts that long, it will need replacing again. This IS the third time that I have reported it and GM is apparently no closer to a fix than they were 9 months ago. Told you to fine the hell out of them and see how quick they come up with a fix. Last time both lower beam headlights became inop, had no choice but to drive home on high beams.

Headlights turn off at night while driving. At first they would come back on with dash switch, now that has no affect. Hi beam switch would help switch hi beams then back low beams fixed it. Now sometimes that doesn't help. Have to pull over, shut off engine and restart, but that is Hell, driving with no light to find a safe place to pull over. Really can't tell you how many times they have failed during the day drive.

Trailblazer LX 4cl

  • Automatic transmission
  • 115,000 miles

While driving at night, going anywhere from 45 to 70 mph, the lights shut off. I cannot see other drivers and they cannot see me. This is very dangerous and scary at the same time. The high beams are working but those are the only lights that I have to use. In return this is a dangerous and scary situation to other drivers.

Overall, this happens to be one of the best vehicles I have ever owned but this is a very serious problem that need attention. With all of the complaints surely the company WILL take ownership of this defect and satisfy their customers complaints. We have invested a lot of money in choosing our vehicles and would like the assurance that the company will rectify this issue because excellent customer service can make or break a company.
