While driving up a long incline on I-10 vehicle behaved as if the ignition had been turned off and key removed. Ie: engine off, no lights or accessories, no warning lights on dash. Traffic was heavy and my wife was fortunate to safely coast into shoulder. Incident recorded with Buick, have reference number.

Driving at 45mph, smelled smoke from what appeared to be an electrical fire. Approximately 1/2 mile driving time, the engine and all power cut off. Got someone to help push the car off road when another person notice there was a fire coming from underneath the engine. Fire department was dispatched but engine was completely engulfed by the time they got there to put out the fire. Police and fire marshall determined fire came from electrical fuse box initially. Car was totaled by insurance.

The contact owns a 2006 Buick Lacrosse. The contact stated that the head lights failed. The contact took the vehicle to the dealer where it was determined that the relay switch burned out the panel box. The failure mileage and current mileages were 121,000.

Coming home from the hospital on I-65, with my mother the low beam headlights suddenly went out we managed to pull over safely but shaken up. After a few minutes the lowbeams came back on. We have had recurring problems with this but never knew when to expect it to happen. We replaced the relay and solved the problem temporarily. The car now has 96000 miles and no low beams. If General Motors don't think this issue is severe enough to do a recall maybe they might respond to a class action lawsuit. Once I decide to sell this car it will be the last Buick I ever own.

I went to the parking garage after work, and had difficult getting into my vehicle. The remote did not work. When I put the key in the lock, it would turn but not unlock the door. After about 15 minutes, I finally got into my car. I picked my sister up and went to the restaurant. I was unable to get out of the car. I tried the remote, the inside release and pulling on the lock. I finally got it to release. Then I had problems closing the door. We got it shut but when we came back from the restaurant it was open. I dropped my sister off and drove the mile home, the door again would not open nor would the passenger door open. I am claustrophobic and became very upset. I went back to my sister's and got the door open. We left it ajar, and when I got home it still would not open. After about another 15 minutes, I finally got it to release. Then next day when my husband took the car over to the dealers, he could not get the door to open. He was able to get the passenger door open and climbed out that way. I can understand the electronics malfunctioning, but not the manual system. I really feel this is a safety hazard. I just got off the chat line with General Motors and received no satisfaction or resolution. It was $300 to have the driver door lock actuator replaced/repaired. I still have no explanation as to why the manual system did not work..

Low beam headlights do not work. Lights worked fine, parked the car in the garage, lights stayed on delay mode and both were fine. Driving home the next night, several oncoming vehicles flashed lights, I pulled into a parking lot to check my lights... no low beam lights. Switched from auto to manual mode, still no low beam lights, high beam lights work fine. I have read that several others have this same problem. Nobody seems to have a solution. I do not feel I should need to pay the dealer to 'analyze the problem' and charge an outrageous price to fix this. This is a definite safety issue! updated 09/10/13

While driving on a three lane highway, the 2006 Lacrosse engine stopped. I was able to cross two lanes and park on the shoulder. Towed to a mechanic and he spent 1/2 hour looking for problem. Tested and no codes. Moved the connection at the distributor module and the problem was solved. Tried to make it fail again by moving, unplug and plugging the connection. I drove home and it has not happened again.

I have had problems with my ABS and traction control, I contacted GM on the matter and they told me they dont cover the braking system, I do consider this to be a safety hasserd, as my brake pedal jumps when I apply the brakes, id like to get satisfaction on this issue.

I am an owner of a 2006 Buick Lacrosse cx, with approx. 47,000 miles. As I entered the underground parking garage, at work, Tuesday morning, I discovered I had no low beams. The high beams and parking lights both worked. I took the car to a very reputable dealer to diagnose. I was told that it was a good thing I got the car there when I did. (I could've had a fire under the hood)...the technician said that the fuse box, against the firewall, under the hood, had melted. This could have been a very dangerous situation, a.E., driving at 65 mph at night, a fire, etc...

Dash lights will not come on when starting the car. This happens on occasion (about 2 times per month). It is impossible to determine when this happens. The dash lights may come on from five minutes to an hour after the car is started. This mostly happens when the car is first started. On several occasions it has done out while driving. GM has offered a diagnoses of the problem but this would only be beneficial if they were off and stayed off when I would go to a dealer. I have tried this any the lights always come back on before I arrive. My neighbor has a Buick the same year as mine and his does the same thing. The dealer refuses to find the problem and says it is suppose to work that way. They are wrong on this problem. When the lights go out you can not see anything in the dash lighted area.

The contact owns a 2006 Buick Lacrosse. While turning the vehicle at 10 mph, the headlights dimmed when the turn signals were engaged. The contact did not know if the rest of the exterior lights also failed. He waited approximately 15-20 seconds before the headlights illuminated again. He turned the vehicle again and the headlights failed. The contact pulled the vehicle over and waited once more for the lights to illuminate. Once the lights activated again, he drove all the way home without using his turn signals. He took the vehicle to the dealer and they attempted to repair the vehicle, but was unsuccessful. There had been no other occurrences since the recent failure. The current mileage was approximately 16,600 and failure mileage was approximately 16,400. Updated 07/09/08
