I was getting off of work and as I tried to open my car I noticed the remote wasn't work. As I approached my vehicle I smelled something burnt. Figured it was coming from the alley. I noticed my windshield wipers were up. I manually opened the car and it smelled worse of burnt. Noticed that nothing was working inside my vehicle. I call security to come and help me and as we open the hood it smelled just as bad. We noticed that the fuse box had a melted hole in it. Once it opened several fused were burnt. I have read that several people have had the same issue. I wish u let us upload pictures of this incident. What if while driving my car had caught on fire or something worse could have happened to me or my child. Luckily I was out of my vehicle when this problem occurred. This issue has to be looked at. Now I have to tow my car out of my work garage pay for that and then pay for my vehicle to get fix which we should definitely get reimbursed for it because it's obvious that this is a recurring issue that has not been fixed. It can turn out to be a big law suit against buick. I had the same issue also with the headlights. I would be driving at night and out of no where my lights would just shut off. Had to replace that also. . .updated 07/21/15 *bf updated 11/9/2015

2007 buick lacrosse. Consumer writes in regards to defective fuse box and seeks reimbursement for repairs. *smd the consumer stated the low beam lights stopped working. He took the vehicle to his local mechanic, where he was informed he was very fortunate the vehicle did not catch on fire, because the fuse box had melted and the wires had burned. The damage was not a result of negligence, but was caused by a flaw in the fuse block.

The car was driven on the freeway. Smell of something burning coming from the hood area. Take the next exit, smoke start coming out of the hood. Stop the car check the hood and the underhood fuse block was burning. The whole fuse is damaged so is the engine harness. It looked like the headlamp driver module and the fog lamp micro-relays were the ones that melted first and cause the fuse box to burn. I couldn't figure out why the fuse box just burned that's why I started looking online if someone else has the same problem. It seems a few people has the same problem. I guess there are unreported cases as well. Something should be done before someone get hurt because it looks like this is a problem the 2007 buick lacrosse has. The car has not been fixed yet. Still trying to find out if it is still worth fixing...updated 10/05/14 *bf....updated 01/12/15*bf the main wiring harness was replaced. Updated 01/15/15*jb updated 3/26/2015

A improperly shielded wire grounded out and caused the under hood fuseblock to melt, some reports on line state that the car caught on fire from the same problem. Came out of restaurant and car wouldn't start. When the hood was raised we could smell burning rubber. Had I been driving it could have been very serious reported to gm to try to get reimbursed. Said because it wasn't on recall that they could not help us. The purpose of the fuse box as we understand is to prevent this from happening.

The low beams on this vehicle had been flickering on and off at night for a few days. Then the low beams would not come on at all on the night of december 2, 2012, high beams worked but the smell of burning plastic filled the car and I immediately shut off the engine. Upon inspection I found one of the relays, presumably the low beam relay, burned and melted inside the fuse block causing a small fire inside the fuse compartment which fortunately contained the fire but destroyed the entire fuse panel (block). This appears to be a well documented and common problem on the 2007 buick lacrosse and yet there is no recall. This is a top tier safety concern as it is only a matter of time before there is a fatality associated with this safety issue. I had the car repaired at a buick dealer for a total of $616.15. This type of failure should not happen on a vehicle of this age or mileage, yet I am reading that I am not the only person to experience this same exact issue. I am researching all claims and considering a class action lawsuit to have this problem corrected. I feel as though gm owes me my $616.15 back and should correct this issue via a mass vehicle recall.

I have had problems with my low beam headlamps for a couple of days now not turning on at night or they begin to flicker on and off causing me to drive with my high beams on.. But today I smelled an electrical fire as I parked and exited my car and saw smoke coming from under the hood and it turns out the relay for the headlamps was burning and melted. I removed it but it caused damage to the other relays next to this one and melted the actual fuse center. I haven't checked for possible damage to other components of my car yet but I will in the morning... This looks to be a common problem with this make of vehicle and still no recall has been made..
