2013 Buick Lacrosse. Consumer writes in regards to unpredictable power outage. The consumer stated when the power went out the keys would get stuck in the ignition. When this would occur the consumer would remove the battery cables from the negatice and positive. The consumer then put the negative back in the battery and tap the postive causing a spark to reset the power.

For months prior at night my low beams would dim and get brighter periodically. Then as I was driving one morning I began to smell an electrical burning smell. Luckily I was on my way home which was less than a half mile away. When I got home I opened the hood and saw smoke coming from the fuse box. I immediately disconnected the negative battery cable and proceeded to investigate what happened. Upon further investigation the hdm module had failed and was melted right into the fuse block. If I had driven any longer than I did I feel like my car would have certainly caught fire. Luckily I got home safe and prevented any further damage from my car.

2006 Buick Lacrosse. Consumer writes in regards to head lamp driver module recall notice. The consumer stated while driving, the windshield wipers started operating on their own. The consumer stopped and inspected the vehicle and discovered smoke coming from the fuse box. He disconnected the battery cable, but smoke was still coming out. He removed the cover from the fuse box and a part of the fuse box had melted and smoke continued to come out but after a minute it stopped. The wipers extended over the windshield and would not work even when the battery was re-connected later. The fuse box and wiring harness had to be replaced.

While driving home from store my wife and I smelled something burning three blocks from home. We got home and I checked under the hood and the relay/fuse block on the passenger side was hot and slightly smoldering. I waited a while and the popped off the fuse block cover and saw the hdm module (according to the diagram in the manual) had melted and fused to the block. The melting and burning had also affected the surrounding relays and fuses. I immediately disconnected the battery and scraped away the burnt, fused portion of the hdm relay and visually checked the fuses which were singed or partially melted and replaced the bad ones. I do not have anything to check the relays with. My wife is on oxygen 24-7 and had a tank in the passenger front with her at the time of the incident which, if a fire had spread, could have become a catastrophic incident. After cleaning out the burnt portion of the fuse box of charred remains from the hdm module, I re-connected the battery cables and was able to start the vehicle without incident. The headlights would not work and some gauges appear to be erratic in their readings ( fuel tank and mileage). I then got online and found many 2006 thru 2011 Buick's have reported this very same problem but no recall ( to my knowledge) has been issued for this highly dangerous and possibly catastrophic issue inherent in gm and specifically Buick products. I purchased this car new and I have never received a notice or recall of any kind. I am in the process of having diagnostics and repairs done by an authorized gm dealer and will know more (hopefully) in the near future.

Wednesday morning, I had an appointment, then stopped at the store, came home pulled into the garage, came in the house, my husband was outside, & smelled rubber burning, he went out front to check, I had left the garage door open, he turned around & looked in the garage, smoke was coming from under the hood of the car. The whole relay switch box was melting & the smoke was very bad, he got the battery cables off. I took an extra warranty on the car when I bought it, but am told it does not cover electrical fires, what a rip off, I traded an 2001 Buick limited on this 2008 Buick Lacrosse, on 07/17/2013. I am really upset about this, & with the dealer ship, & general motors. I am told there are no recalls for this problem, & it is very rare for this to happen, but this is not what see on the web.
