Parked with low beam headlights on and they suddenly shut off. Turned them off and back on manually with no affect. Turned on the high beams and had light. About 5 minutes later while driving the low beams returned. A second incident occurred on September 25, 2014 while driving 60 mph. Low beams went out was able to switch on high beams, although somewhat diminished, low beams returned within 10 minutes of driving with diminished high beams.
While driving on the highway in the rain, my headlights went out. I was terrified. Turning the switch on and off would not fix the problem. I took the car to the dealership. They said they could not duplicate the problem and would not fix it. I had taken the car to the dealership shortly after purchase in 2009 and had complained of leaking seal on the top edge of the driver's side door in the rain. Water would drip all over my left arm, shoulder and arm rest. They said they could not duplicate the problem and would not fix it. Now the headlights will refuse to work on an intermittent basis. The dealership will not fix it. The dash reads headlights suggested but they will not come on. I can use the dimmer on the steering column and the bright lights will work, but driving with bright lights into oncoming traffic is dangerous. I need to have a dealer fix this problem. I took the car through a car wash for the first time the other day and the lights have been acting up again. Please have someone contact me and authorize repairs at the dealership. I am afraid to drive even a short distance at night not knowing when my headlights will suddenly go out again. It has happened several times now. It really scares me and concerns me that a dealership would not repair the problem. Updated 09/10/lj the consumer also stated there was a noise coming from the steering, a squeaking noise coming from the dash area, and water would drip through the top door, every time it rained. Also, there was a vibration issue, so the dealer replaced the tires, but it didn't resolve the issue.
The contact owns a 2007 Buick Lacrosse. The contact was driving at an unknown speed when the headlights failed and would not re-illuminate despite the contacts attempts. The contact had to utilize the high beam lights and the vehicle was taken to an authorized dealer where the contact was advised that a relay switch would need to be replaced. The vehicle was not repaired. The failure and current mileages were 58,000.
In the past six months, the headlights on my 2007 Buick Lacrosse have turned off on their own several times. Twice this has occurred at night and twice during twilight. Adjusting the headlight switch does nothing to affect the lights. This problem affects the low beam lights only. The car has been taken to the dealer with this reported problem 3 times. They report that no problem was found, but they did replace a part once that has had not remedied the problem.
