Print this page 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.

Passenger low beam headlight has gone out several different times over the 5 years we've owned it. Had a relay switched out that helped for a little bit. Also had to change the wiring right by the headlight because it was burnt up. We took it to Chevy in devils lake, nd. I seem to notice other Trailblazers driving around with the same headlight burnt out.

Occasionally headlights go out at night while driving. I see that 2006-07 were recalled but many others with a 2005 also complained of the same issue I'm having.

The low beam headlamps fail simultaneously. This occurs while driving at night. I have replaced the hdm solid state relay twice, but after a time. 6 months to a year, the failure occurs again. Once the hdm module became to hot to touch upon failing. This last time, the third, the lights may come on again after some time has passed. It is as if the module is short circuiting or overheating leading to a short circuit.

While driving at night, low beam headlamps go out completely. High beams still work and are the only option for getting home. Has happened multiple times. The first time it happened we were traveling away from home. We were on the highway and realized that we had no headlights. Very dangerous situation and from looking online - this seems to be a very common problem without a solution. Shop can't help unless they are doing it at the time.

The contact owns a 2005 Chevrolet Blazer. While driving at approximately 30 mph, the low beam headlights were activated and illuminated intermittently. The instrument panel warning indicators also illuminated. In addition, the high beam headlights experienced the same failure when activated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 150,000. The VIN was not available.

Low beam lighting was out when the vehicle was turned on at 2030. It did not come on while driving (20 minutes) so I had to use the high beams. I did check multiple times while driving.

I was leaving a parking lot at dark and my low beam headlights were working. After exiting the parking lot to the road, I note that the low beams were out. I then had to drive through town on the busiest roads with my high beams on. It was approximately 2100 and the temperature was in the 70's.

While driving after dark, the low beam headlights went out. The high beam lights continued to work. This is a recurring issue and seems to occur more once the vehicle has been running for some time. The lights did not come back on until the car was left parked overnight.

While driving southbound on I-75 in Michigan at approximately 9:10 pm on August 16, 2015, the low beam head lights went out near mile marker 180. The high beam lights and running lights continued to work. The low beam lights remained off until after I exited I-75 at the southbound 155 exit. After leaving the exit and driving an additional 4 miles, I again tried the low beams and they worked. I later got back into the vehicle (after it was off for approximately 30 minutes) and the low beam lights were again off. They would not come back on and I left the vehicle. The following morning, the low beam lights were functioning again. This situation has been reported to the executive customer service office at GM and they have stated that there is not a current recall and therefore they will not repair it.

The low beam headlight on my 2005 Chevrolet Trailblazer turn off while I am driving down the road with no notice. The first time this occurred was on lawndale/7 mile road in saginaw county Michigan in June 2014. The incident has happened several times since, most recently on 8/8/15 on greenwood road in alger mi. The low beam lights go out for no reason and cannot be turned back on. The high beam lights will work. The low beam lights will later turn on on their own. It generally takes several minutes before this happens. Several times this has occurred on dark, county roads which increase the danger to the occupants of my vehicle and other passengers on the road. I have contacted GM and their executive office and was informed that while the issue is a recall for the 2006 model year, because my vehicle was built in June 2005 it is not covered.

While driving home one night around 9:30 pm from the local wal-mart, I turned out onto a highway/public street and my head lights went out. They would not come back on no matter what I did. I went home thinking my lights were completely out but when I pulled into my drive and hit the high beams they worked just fine. My low beams did not come back on until early the next morning. It has happened several times since then.
