Headlight Switch problems of the 2008 Buick Lacrosse

-door locks won't work with switches, key bof, and sometimes manually. Car had 49000 miles and was eight years old when problem began. Problem occurs while driving and stationary. Dealership estimate to repair is $900. Concerned that will not be able to exit vehicle in a emergency situation. -interior display lighting goes dim when headlights come on. Can not see some of the displayed information during daylight. Dealership said it could not be repaired.

On Dec. 18th my wife and I were driving at night going to a christmas party when the low beam headlights went out without warning. I switched to the high beams as they were still functioning. We went the last mile to our destination on the high beams. I turned off the car to see if that would re;set the lights, it did not. We went to the party and came back to the car apx. 3 hours later. I started the car and the low beams came on. . After about 1/2 mile they went out again. . So I pulled over and shut off the car to see if they would come on upon re-start,they did not,so we continued on with high beams. After about 10 minutes the low beams came on for the rest of our trip home. The next day I researched the issue on-line and discovered a recall had been issued for this problem I contacted the local Buick dealer and was told they were of the problem but had no direction on how to fix it from g. M. My wife called another area Buick dealer and recieved the same reply. . She was able to get a hold of g. M. And was told they were aware of the issue and would get back to us. . We never r got any recall notice from g. M. I had to print all the forms from the NHTSA web site. . Seems to me that this a multi million dollar law suit waiting to happen after something really bad happens (it is only a matter of time). This problem is not just with te Buick Lacrosse there are other models involved. . So what can be done to get g. M. And their dealers to fix this?.

In January of 2015 we received a recall notice from gm concerning the headlight driver module (gm safety recall 14291). We called the dealer several times to be told they were waiting for parts. We began experiencing a "headlights recommended" signal several times in broad daylight, but lived with it. When I was in the hospital in October recovering from cancer surgery my wife experienced a headlight failure when driving home alone at night. A neighbor took the car to the Buick dealer and they installed a relay, part #15016745. We then noticed that the left front headlight and the right rear tailight were not lit. As soon as I was cleared to drive I took it back and they insisted that it could not have been their fault, that it was just a coincidence that it happened at that time. I paid the $68. 93 for new bulbs. . Read more...

Underhood fuse block caught on fire from the headlamp driver module micro-relay #35 melting down. Headlights went off and the battery started draining. Pulled over, turned off the car, and opened the hood to discover that the #35 micro-relay was arcing and had melted itself to micro-relays #44 windshield wipers and #38 air conditioning compressor. Both windshield wipers and air conditioner was off at the time. Even though the engine was off the relay continued to arc and was melting the underhood fuse block. Grabbed an insulated set of pliers and pulled the #35 micro-relay (the #44 and #38 relay came out at the same time). Arcing stopped with the micro-relays removed. I have filed a previous report on the #35 headlamp driver module micro-relay, because it had turned off the low-beam headlights while I was driving, at night, on the highway. Turning the light switch to manual-on did not turn the low-beam headlights back on. I had the #35 headlamp driver module micro-relay replaced and it too proved to be defective. After just a few months, it started turning on the headlights about 10 minutes after the vehicle was turned-off. Had to have my vehicle jump started, replaced the battery, and replaced the #35 headlamp driver module micro-relay, yet again. The 3rd #35 headlamp driver module micro-relay, caused an electrical fire, costing me over $700 to repair. Apparently there is no fuse to prevent the melt-down of the micro-relays. There is no caution, and no warning in the owners manual, to advise the user about what to do in the case of the low-beam headlights suddenly going off. There is no protection against an electrical fire being caused by the #35 headlamp driver module micro-relay, or any other relay from starting an electrical fire.

Headlights went off while driving 60 mph in the dark and no nearby light sources were present. Turned headlight control to manual and still no headlights. Stopped vehicle and everything but the headlights were still working. Turned off the air conditioning, the fan, the radio, and still no headlights. Turned car off and back on, still no headlights. Turned car off again and waited 5 minutes and restarted car and headlights came on. This has happened 2 times now, 3 months apart. Dealership denied any knowledge of this problem the 1st time I talked to them, but admits now that several other people have also tried to get this problem fixed but they were unable to duplicate the problem. If I had been driving on a curve, I would most likely be dead now and they would be guessing why I ran off the road (user error), when they know there is a defect in design. Light switch on manual should bypass everything except the fuse.
