The multi function switch does not work properly. When going around curves and corners you can't dim the headlights. Because the steering wheel doesn't allow the lever to go far enough to catch. Now my headlights will not turn on when the they are suppose to. My cruise control doesn't work. My a/c stops cooling when the speed reaches 60 mph but if I move the m. F. S. (aka turn signal) it gets cool again for a few minutes. The other night my lights went off when I was meeting a car with its headlights on bright. It was a dark stretch of road. I almost ran in the ditch.

Traveling at night, once in heavy traffic with lights on low beam and other times in light or no traffic with lights on high beam, all outside lights go out creating a very dangerous situation. Does not matter if the manual switch is used or if the lights are on automatic. The only thing that makes them come back on is switching the high/ low beam switch. Miles traveled or length of time traveling makes no difference . . . Random occurrence. Replaced the headlight switches at a auto repair shop made no difference.

While driving, when high-beams were turned on the entire headlight system would shut down leaving driver with absolutely no visibility. Fortunately the headlights did come back on as the dimmer switch was activated and the low-beams did come back on. I can only use my low-beam headlights as this issue happens most times the switch is activated.

Failure Date: 04/15/2015

We have had our 2005 Buick lacrosse for about six months now and want to report this lighting safety concern. This headlight incident with our Buick has actually happened to us, three times since mid April. The first time it happened, we were driving one evening, suddenly our low beam headlights went off. This was very frightening as it was a dark stretch of road, with traffic. I slowed and found a reasonable safe spot to pull over. I tried turning the headlight switch in several positions with no success. We normally keep the headlamp switch in the auto position. Our low beam headlights still were not coming on. I then found I cound turn my high beams on, so I did to illuminate the road and be able to drive home. Driving with only high beams is both dangerous and illegal. It can be blinding to on coming traffic and I could have been cited if I had been pulled over by the police. From where my low beams went out, to home was about 4. 5 miles. Right before pulling in at home my low beams came back on. I turned off the high beams and still had the low beams. Quite unusual. Then within a 2 to 3 week stretch, my low beam headlights went out twice again. Right away, I turned on my high beams and within 15 - 20 minutes, low beams came back on. While I'm able to light up the road using the high beams if this happens again - it still is not a safe alternative. There is an issue. I don't know if it's a module problem, bad wiring, I just don't know. I did find out on the internet, other same year, make and model drivers have experienced this same issue. Lights going out for no reason while driving at night needs to be addressed. Thank you for researching and getting gm to do the right thing and have them fix this safety issue.

Failure Date: 01/26/2015

The contact owns a 2005 Buick Century. While driving approximately 60 mph, the low beams stopped working and hindered the contact's visibility while the vehicle was in motion. The contact had to hold the switch to get the high beams to remain illuminated due to the failure. The vehicle was taken to a dealer where it was diagnosed that the multi-function switch on the column for the lights needed to be replaced, including prematurely deteriorated ground wires. The dealer stated that the parts were to be ordered, but were not yet available for them to provide a specific date of when the part would be available to complete the repair. The contact left the vehicle at the dealer until the part was available. The manufacturer was notified of the failure. The approximate failure mileage was 118,000.

Headlights go out completely for a few seconds until the bright/dim is switched and then come on. This has happened infrequently since fall of 2014. Doesn't happen when at dealer service or when we test lights after returning home. Dealer says can't be repaired until they can get the incident to repeat. Lights are fine for a while & without warning the situation occurs again. Very alarming! a friend with a Buick regal 2002 has the same problem.

Pulled out of gas station to enter street and noticed headlights were not on. Pulled out the head light switch and nothing happened. I pulled back on the bright light switch and the lights came on. Mechanic had told me to try this since this same thing has happened before. Last year, I took the car to the Buick dealer for something else, but I brought up having a diagnostics run to see if it would show anything about the light problem. They told me that it wouldn't show up. Now I am afraid to drive this car at night. I have read many letters on the internet regarding this problem. Gm should fix this problem. It would cost about $700. 00 to get the switch replaced at the dealer. Does someone have to die if the lights go out while driving?.

Low beam headlights suddenly stopped working while driving at night. I bought the car used a year ago, and the multifunction switch was replaced just before I bought it. After doing some investigation, I discover it's a very common, almost universal problem with these vehicles that costs almost $800 to repair. Gm hasn't issued a recall for this defect. . . . Yes, I said defect.

While driving at night, my headlights just go out! this has happened often in the last month and a half. I commute an hour to work and it happens at least once a day. It does not matter if they are on manually or automatically, it does not matter if they are on low or high beam. I discovered that the lights come back on if I hit the dimmer switch. This is a dangerous situation and I believe that it is worthy of investigation and a recall being issued. I have seen many complaints online about this situation. What will it take for a recall? will it take someone getting killed in a head on crash?.

Almost every time the headlights are changed from high to low beams the lights will shut off compleatly and I will have no headligts at all, I have gone out and purchased a new turnsignal switch and plan to put it in as soon as posible and I will have the old part still. The front drive assembely will grind any time a tire loses traction and spins in either the rain or snow on pavement or off the road in a driveway so my car has been driving in one wheel drive instead of two wheel drive, I have not had the chance to go and buy a new drive axel assembely to correct the problem.

While driving home one night, my headlights just went out! this has happened often enough we now do not drive our car at night if at all possible. Through research online and testing it ourselves, we determined that the lights come back on if we flick the dimmer switch. This is a very dangerous situation, and after reading other's similar experiences at aboutautomobile. Com (15 different entries), we believe that this is worthy of investigation and a recall being issued. We did take the car to a mechanic who was not sure what might be the cause. Now that we have some idea, we will return to him and get an estimate for repairs. From the online research, we can expect it to cost approximately $600 or more. Thank you for your time.

I was driving on the interstate to visit friends at about dusk. I always drive with the headlight switch in the "auto" position, but because of weather conditions I switched to the "manual on" position. I continued to drive for another hour and when I got to within 10 minutes of my destination, the interior dash lights and radio started flashing. My headlights were also going off and I could hear the relay on the computer (passenger side) clicking. I stopped and inspected for a shorted wire but found none. I switched to the "auto" position and was able to complete the drive and return back home without recurrence. Testing it again at home the headlights would go on and off in the "manual on " position. After exercising the headlight switch through all the positions numerous times, I could not reproduce the problem. . I believe that the problem was caused by a unused contact on the headlight switch that became oxidized and the low voltage caused the loss of headlights and reaction with the computer controlling them. This is a very dangerous design to be driving at interstate speeds and loose your headlights.

Was driving after dark on country road. Switched on bright lights after a few seconds headlights went out. Pulled over to side of road. Pulled light switch on and off several times and lights came back on. Was afraid to use bright lights again. Is very dangerous as was I was on straight away and little traffic at the moment. Could have been on a curve and could have resulted in crash and or loss of life or at least injuries. Will go to mechanic Monday and hopefully can get repaired. Was looking for safety bulletin and or recall or advisory.

The contact states the headlights go out for a few minutes and then they come back on. This has been occurring for the past week. Because it can be duplicated by pulling the turn signal switch forward it is a problem in the steering column with the turn signal and headlight switch. There have been no repairs made to the vehicle, and a mechanic has not inspected the vehicle.
