general problems of the 2010 Buick Lucerne

We have a Buick Lucerne 2010. We went out it would not start. Tow it to dealership they replace the fuel pump. We did. Get it home next day it will not start again. Tow it to dealership again. This time they find melted wire connectors. Under back seat and on a fuse box. They replace them it starts and melt them again. This time they call to junk yards to get a used fuse box and connectors. Because of cost. The junk yards did tell them it's a known problem with these cars and they sell these fuse boxes and connectors sell as fast as they get them. We said no used parts on this car. Come to find out that gm now's about this problem. And has not done anything about it. They meaning gm. Has even put out papers on the internet as how to try and fix it. Such as cut the insulation around the fuse box. And even cutting the seat belt bracket. My wife drives this car everyday. Now she is afraid of it. Because if it happened once could it happen again. I don't now. I have drove gm's all my life but am not happy about this. What do I do. Please help. I am a retired firefighter and I do not want her to drive this car if it could catch fire.

See gm bulletin # 15-na-051 vehicle died, required tow, found out due to fuel pump relay per bulletin cited above. Rear seat bracket interfered with fuse box, disabling vehicle requiring tow. Vehicle repaired at owners cost. Due to safety factor involved, the seriousness of the situation, for what portion of the costs of repair will the manufacturer be responsible?.

When to start vehicle on the above date and it would not turn over, the day before while I was driving I smell something burning and today it does not start. Reading about problem and complaint on the internet I realize that this is a common problem with the vehicle years 2006 until 2011. It seems there needs to be a recall on these vehicle, because a fire hazard could happen and the vehicle can catch fire while driving or stopped.
