The headlights are not working properly. Sometimes the headlights work but other times they turn off. The high beams and marker lights are not affected. This also applies to the daytime running lamps and occurs in motion or at a stop.

As identified in recall # 14V755000, the low beam headlamps will turn off at random times. This have happened several times during darkness hours and is increasing. In one case, an accident was barely avoided. I was recently (Nov. 13, 2015) told by the GM dealer - the vehicle VIN # does not list this as a recall item. "??" last occurence is listed below.

Both rear brake lights failed simultaneously, even after fuses were checked both under the hood and behind the drivers side fuse box (fuse #12 & fuse #34). This is a road hazard and faulty wiring should be covered. Front left headlight was found to have switch with melted wiring as well, changes by mechanic and I was informed it could have caused a fire. This vehicle has 3 recalls thus far that are extremely dangerous if such faults can cause a fire within the electrical wirings. I would like to get compensated for the work done, the brake lights faulty wiring should be covered under the recall as the local Chevy dealer refuses to fix it.

The low beam headlights on my 2006 Chevrolet Trailblazer ext continue to go out. The problem started about 3 years ago where initially the drivers side low beam light would turn on and off intermittently. Then, the pig-tail wiring to the bulb burned up (luckily not causing a fire, which my mechanic said could have happened). The pig-tail was replaced and the light worked, but only for about 8-10 months, which the wiring burned up again. The same mechanic replaced the wiring again, and this time it only lasted about 6-8 months, and he replaced it yet again. This final wiring replacement lasted, but the relay went up. We replaced the relay several months ago, but now the light is starting to work intermittently again, worrying me that the pig-tail will burn up again and possibly catch fire. The first time it burned up, I noticed some very noxious fumes while driving which nauseated me terribly. I understand other trailblazers have this problem. I would love to see a recall on it as there is a similar recall on some of the trailblazers for the brake lights.

My lights dim and flicker along with the dash board instrumentation and the volt meter dips down to around 12. This problem initially occurred about a year ago. It seems to have some sort of short. I called my local auto shop who said he would take a look but doubted he would find the problem since he couldn't with the last one he looked at!! I really enjoy this vehicle and I'm hoping that someone stumbles across the real issue and is able to help me to fix my trailblazer.

The bearings on the alternator are wearing and need to be replaced, the vehicle only has 29,000 miles and according to my mechanic they should not be worn this early and should be replaced as soon as possible; this is definitely a safety issue and a faulty part that I should not have to pay to have replaced. The fuel level indicator has stopped working over 2.5 years ago. I did receive a letter saying that the part may wear out prematurely and they are willing to pay 50% of the replacement but if it wears out prematurely then the part is faulty and I should not have to pay to replace the part. The backup light panel is bad, I tried to replace the bulb but the problem lies with the panel, faulty part again.

My fuel gauge on my 2006 Chevy trailblazer slowly stopped to where it is no longer working at all. Also, suddenly today, both of my dim (low beam) head lights stopped working after having the battery replaced. Have checked fuses and they are ok. I have seen many complaints for both of these issues.

The air conditioning on my 2006 Chevy Trailblazer ext stopped working. The problem was the blower motor resistor module and resistor module connector. The parts had melted together, causing the wires to become loose at the connection. Apparently this is a common problem with my Chevy model. There are many online postings indicating that the problem could cause a fire. Chevrolet company refused to even look at my vehicle until I paid a $110 diagnostic fee. The service technician immediately knew what the problem was and explained that it was a common problem with my model and the Tahoe. The gas gauge also stopped working recently which I was told by the technician that it too was a common problem. There are numerous complaints on these parts as well as the brake light circuit boards, which also went out on my vehicle. The technician once again said that it was a common problem. These parts seem to be failing shortly after the warranty expires. There are many issues with the electrical system in this vehicle. The problems are hazardous safety issues and are known to the Chevrolet corporation. I was able to find the parts at nearly 80% cheaper than what the dealer wanted to charge me, not including the labor and diagnostic fee. Safety recalls on these parts should be issued.
