Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

I own a 2002 Chevy Trailblazer and I have had my headlights checked because not always but once in a while they just completely turn off sometimes at night time while driving. I took it in to a repair shop and nothing was found wrong with it but the problem continues I have to have headlights and brake lights changed like every month or so my truck one day didn't turn on couldn't figure out what was wrong with it sat in my garage for about 3 days and everyday I would try to turn it on but nothing after the 3rd day went and tried again it came on without a problem and it's been okay just the problem with my headlights still going off at night once in a while. I know 2 other people who have 2002 Chevy Trailblazers and have had kind of the same problems. I believe that their is an electrical problem with the 2002 Chevy Trailblazers.

The passenger-side low beam headlight socket caught fire and melted. This same socket and bulb were replaced due to melted contacts only 4 months ago. I was aware of the current situation as there was a strong burnt odor inside the vehicle. The fuse for the headlight did not blow in either situation.

My headlight on the drivers side of the vehicle is out. I can not just replace the bulb because my wires that connect the headlight assembly to the wiring system is burnt where it looks like it has tried to catch fire. Now my whole lighting system is flashing and when you drive down the road the headlights flash and dim down.

I have had to replace both drivers side and passenger side brake lights numerous times only to have them burn out within 4-6 months of installing new ones. This cannot be normal.

  • 89,000 miles
The contact owns a 2002 Chevrolet Trailblazer. The contact took the vehicle to the repair shop for routine maintenance, in which the passenger side headlamp was replaced. Two weeks after the repair, the passenger side headlamp failed. She took the vehicle back to the repair shop and they inspected the headlight and concluded that the wiring melted. The contact then called the dealer in reference to NHTSA campaign id number 06E025000 (exterior lighting:headlights) and was informed that her VIN was excluded from the VIN range. She would be responsible for the repair costs. The vehicle has not been repaired. The contact is in the process of notifying the manufacturer. The failure and current mileages were 89,000.
