Going down highway 70 MPH straightaway car stalled able to get to side of highway pulled off seat found fuse box temp hot when cooled down noticed fuel relay switch burnt out. Common problem with car due to engineering of seat brackets hitting fuse box and damaging it. This is the second time in 5 years fuse box has been replaced by certified dealership. Obviously problem is with the engineering of seat bracket but apparently dealer does not take me seriously and did not trim seat clips per my specific request bc there is only a bulletin from gm 15-na-051 not a recall. Several complaints have been made and must be common enough for a bulletin luckily no one was tailgating or this could have been a very serious accident.

I own a 2009 buick lucerne that I attempted to start the vehicle on random occassions. On another occasion the vehicle stalled on highway 49 in the middle of traffic. It fails to start, some relays are hot even when the car is off, fuel relay has been replace 4 times and it gets extra hot and will almost burn your hand, the fuse box is melted partly and has a burning smell. The fuel pump voltage was checked and is good. On the last try to crack now the driver door windo and door lock is not working. There is no corrison under the fuse box. Buick does not have a recall out on the fuse box or relay. The vehicle had to be towed 25 miles. This is a safety hazard. I have a disabled daughter who is transported in my car and I worry about the safety of this vehicle. Buick is aware of this issue with this particular car. The bucik forum and the federal safety agency websites both have complaints about this issue. The manufacture has been notified. It will take accidents, injury, or deaths for this issue to be resovled it seems. As buick and dealers continue to sell these cars many peoples lives are I jeopardy. I have reviewed pages on complaints and again buick is aware of these issues.
