The fuse box or fuse holder under the back seat had the fuel pump relay fail due to pressure on the fuse box lid from the seat above it. This is a known issue by Buick as they keep the fuse box in stock (for about $300) I have owned two similar Lucernes with this issue. The fuel pump relay caused enough heat to melt into the fuse box, causing a disconnection. This caused the fuel pump to stop pumping, causing the car to stop running. The problem can be confirmed by calling any Buick dealer. I'm sure they have had several examples of this issue besides my pair. There are many examples mentioned on the internet, as well as videos as to how to fix it. There are no warning lamps prior to the failure. The engine dies and refuses to restart.

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 This is the second time in 5 years fuse box has been replaced by certified dealership.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.

My 2009 Buick Lucerne would not start in my driveway on the morning of June 8, 2019. The mileage of the vehicle is 109466. The engine would crack but not start. I found that the relay for the fuel pump was burnt which is located under the rear seat in a fuse box. This was replaced and the vehicle started again and ran. That evening after driving approximately 160 miies, the vehicle shut off while traveling at a speed of 45 miles per hour. I lost all power functions of the vehicle but was able to avoid having an accident while pulling off the road. At the time my wife was in the front passenger seat and my mother was in the rear seat behind my wife. The fuse box is located under the rear seat behind the driver. As long as we owned this vehicle nobody has sat behind the driver as I'm 6'3" tall. The vehicle was towed to countryside auto group located at N8167 kellom rd. Beaver dam, wi 53916. The service department there replaced the fuse box, replaced the relay with a low profile relay, and trimmed the metal seat brackets so it would not push down on the fuse box. The technician stated that from the weight of people sitting on the seat put pressure on the box which caused the relay to short out and fail. The repair cost $647.79 after researching this problem I found out this is an issue with the 2009 Buick Lucerne as there is a service bulletin #15-na-051. It clearly shows how to correct this problem. My concern is the safety issue related to this problem is you lose complete power function of the vehicle which could happen at anytime. There should be a safety recall for this problem no matter what the mileage of the vehicle is at time of failure. I will include a pic of the burnt relay. I was not returned the melted fuse box.
