Was driving at night, vehicle lights went dim, then out completely. Pulled over to side of road. Smelled fire, opened hood, smoke coming from fuse block / box under hood. Looked at fuse block and several relays were melted and had melted a portion of fuse block. There are several other complaints like this posted online.

I have had problems with my low beam headlamps for a couple of days now not turning on at night or they begin to flicker on and off causing me to drive with my high beams on.. but today I smelled an electrical fire as I parked and exited my car and saw smoke coming from under the hood and it turns out the relay for the headlamps was burning and melted. I removed it but it caused damage to the other relays next to this one and melted the actual fuse center. I haven't checked for possible damage to other components of my car yet but I will in the morning... this looks to be a common problem with this make of vehicle and still no recall has been made..

Night highway driving the low beam headlights suddenly go out. Bad. High beams are ok. Fog lights are ok fortunately so I could drive home safely. Turn signals normal. Only the low beam headlights appear to be affected. They resumed working the next vehicle use, the next day. Updated 9/19/13 updated 09/24/2013

While driving down the highway one night the low beams suddenly went out. I was force to use the high beams until I could pull over. Inside the car I could smell something burning, something electrical. Once I pulled over I notice smoke coming from under the hood and that the fuse block under the hood was on fire, which hold fuses and relays. The two relays that was affected were the low beam and high windshield wiper, so they no longer work.

The contact owns a 2007 Buick Lacrosse. While the vehicle was parked and unoccupied, the emergency horn sounded unintendedly and black smoke emitted from underneath the vehicle. When the contact approached the vehicle, he began to inspect underneath the hood area and noticed the fuse box and wires were burnt severely. There were no flames present. The vehicle was towed to an authorized dealer, who stated the electrical harness would need to be replaced. The vehicle was in the process of being repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 45,000.

Driving a distance of three miles car stalled five times. Started again each time dealership sold me a new battery three days later--acceleration quit, going down the road in heavy traffic. I engaged the accelerator with no response. Able to pull over and turn off key and then start again and proceed. Dealership told me that the computer showed no problem with the car. Two days later the car stalled in my mobile home park, started then stalled and wouldn't start. When I tried to start the car it wouldn't. then when I tried to start again and released the key, the starter grabbed the key and kept grinding momentarily. Then when I tried to start it the starter clicked as if it were gone. I parked it for the night and called aaa in the morning. The car started right up and was driven on to the truck.. I was told I needed two parts a starter and something else. That was on Monday. It's Thursday now and I'm waiting for another part. I was told the dimmer switch had shorted out and had been affecting the whole system. It is now Thursday afternoon and my part has been snowed in. There is none to ber had in the whole city of tampa Florida! I am a snow bird and am thankful I wasn't on the road to Michigan when this happened. Losing acceleration and/or stalling in heavy traffic is a very dangerous situation. By the way I didn't trust the century Buick dealership I had the aaa garage work on it this time. It cost me $300. The first time ) the second $0.but with no results. Now I'm in it for more that $400. Merry christmas.

The contact owns a 2007 Buick Lacrosse. The instrument panel indicators and headlights dimmed twice. The second time the failure occurred was while driving 70 mph. When the contact moved the dimmer button, the instrument panel indicators illuminated again, but the high beam headlights illuminated instead of the normal beams. The vehicle was taken to the dealer twice and they found no failures; however, they replaced a part. The contact was unsure of which part was replaced; however, it did not correct the failure. The failure mileage was 49,000 and current mileage was 50,000.
