The contact owns a 2007 Buick Lacrosse. The contact stated that while driving at an undisclosed speed, there was an abnormal odor coming from the vents and the headlights were inoperative. The contact stated that there was smoke coming from the engine compartment. The contact exited the vehicle and discovered that the fuse box was on fire and had melted. The contact used a headwrap to extinguish the fire. No warning lights were illuminated. A fire department report was not filed. The contact was informed that the VIN was included in NHTSA Campaign Number: 15V519000 (Exterior Lighting). The vehicle was towed to a dealer, where it was diagnosed and determined that the fuse box, module, and the circuit board needed to be replaced. The contact stated that the electrical failure had melted and damaged the fuse box and the circuit board. The vehicle was not repaired. …
Low beam headlights randomly turn off while driving at night and day. Causing not to be able to see the roadway at all. Very dangerous!!! They give no warning at all. Only the low beams do this. Bright lights are not affected. There was a recall for this issue but they said my car was not affected. But it is 100% affected by this recall. Ot seems like the Headlamp driver module is overheating. It gets extremely hot. This issue almost caused a very serious accident .
Tl* the contact owns a 2007 Buick Lacrosse. While the vehicle was parked, the low beam head lamps were activated but failed to illuminate. Upon inspection of the fuse box, the contact noticed that the relay was hot and had melted. The contact also noticed smoke and a burning odor. The vehicle was repaired. The contact then received notification of NHTSA campaign number: 14V755000 (exterior lighting). The dealer replaced the head lamp module as a temporary remedy due to the part not being available to repair the vehicle. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the failure. The failure mileage was 16,000.

Low beam headlights can go out at any time while driving. Started happening about 7/2013. Would only drive during day/ had module replaced a year ago when recall notice came out and had lights for a about 6 months with no problem. Was driving going around a corner a couple of months ago, lights went out and I went into ditch causing a bad fender dent and breaking my windshield. Lights can come and go at any time. Thank god, no one was hurt. This could be a major problem. You can use brights, but that would cause blinding the oncoming traffic.
The headlamp driver module burned a hole in the engine fuse box. The hdm is now fused into the fuse box and can't be pulled out to replace it. Recall 14v-755 will replace the hdm. But the GM said I have to pay for the replacement of the fuse box. The hdm failed as the recall said.
I was getting off of work and as I tried to open my car I noticed the remote wasn't work. As I approached my vehicle I smelled something burnt. Figured it was coming from the alley. I noticed my windshield wipers were up. I manually opened the car and it smelled worse of burnt. Noticed that nothing was working inside my vehicle. I call security to come and help me and as we open the hood it smelled just as bad. We noticed that the fuse box had a melted hole in it. Once it opened several fused were burnt. I have read that several people have had the same issue. I wish u let us upload pictures of this incident. What if while driving my car had caught on fire or something worse could have happened to me or my child. Luckily I was out of my vehicle when this problem occurred. This issue has to be looked at. …
The low beams on this vehicle had been flickering on and off at night for a few days. Then the low beams would not come on at all on the night of December 2, 2012, high beams worked but the smell of burning plastic filled the car and I immediately shut off the engine. Upon inspection I found one of the relays, presumably the low beam relay, burned and melted inside the fuse block causing a small fire inside the fuse compartment which fortunately contained the fire but destroyed the entire fuse panel (block). This appears to be a well documented and common problem on the 2007 Buick Lacrosse and yet there is no recall. This is a top tier safety concern as it is only a matter of time before there is a fatality associated with this safety issue. I had the car repaired at a Buick dealer for a total of $616.15. …
I was having intermittent headlight issues with my car, I would drive and the headlights would randomly shut off, I would pull over and they would come back on about 3 minutes later. I did some research and tried replacing the headlight relay, this seemed to fix the problem for about 2 weeks. On the night of April 13, I was at the mall and when returning to my car, it wouldn't start. I had the car jumped and the fuse box caught on fire. The headlight relay had melted and destroyed my fuse box. I had my fuse box replaced and again, everything was fine for about 2 weeks, when I started getting the intermittent issue again. Last night, May 1st, my car again died. This time, all fuses and relays were removed before jump starting my car, but you can look at the relay and see that it has been melting once again. I've researched online and can't find a proper fix for this. …
Tl* the contact owns a 2007 Buick Lacrosse. While driving approximately 65 MPH, the low beam head lamps failed without warning. The contact activated the high beam head lamps to illuminate the road. Each time the vehicle was driven at night, the contact had to engage the high beam head lamps. The contact received notification of NHTSA campaign number: 15V519000 (exterior lighting), however, the part to do the repair was unavailable. The dealer offered to repair the vehicle, but stated that the repairs would not be free of charge. The dealer did not disclose the details of the repair to the contact. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The approximate failure mileage was 38,000. The VIN was unavailable. VIN tool confirms parts not available.
This is the second time it has happened to me. My headlights quit working. The first time it was not as dark and I caught it . My husband took it to sims Buick on elm rd. Where we purchased it. They said there was no recall on it, but we new there was. My husband paid for the new module and put it in. This time it took place on tues. Mar. 29 and 8:30 pm in the dark. I had 3 girls I was taking home from work and my headlights went out. Almost hit someone along the road and there was traffic coming at me. Thakfully the girls guided me into a driveway. My brights worked to get me and the girls home. My husband checked again and was told there was no recall or fix. He bought the module and replaced it himself. Thank god we were safe. But you need to figure it out before someone gets hurt. And make sure your dealers get the information.
