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.

Fuel pump relay under vehicles back seat fried out due to the back seat hitting the fuse box cover and grounding out the fuel pump relay. My child was in the back seat and said there was smoke coming from the back seat and the fuse box nearly caught on fire. After reading online I am appalled that this has not been recalled yet. There was 0 warning, no lights on dash, I did not file a police report or do anything with my insurance as there was no accident. Just a car bomb manufactured by

After being driven normally all day, the car all of a sudden wouldn't crank properly after being parked for a few hours. The car needed to be towed to a car shop. According to a local mechanic, the back seat pressed on the wiring that, in turn, burned up the electric panel and the fuel pump. Due to this, the electric panel and the fuel pump need to be replaced.

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 This is the second time in 5 years fuse box has been replaced by certified dealership.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

When driving the car died and would not start. The fuel pump relay had burned up and so we changed the relay, but that did not fix the problem so we went ahead and changed the fuel pump; this did not fix the problem. The fuel pump relay switch is still getting red hot and not sure at this time what is causing the issue. Having it looked into further. I am not sure if there is a recall on this issue or not but have seen quite a few people having this same issue,

I had just driven the car on a 2 hour trip with no issue. I drove that trip in the morning and that afternoon I went to start the car and the starter was going but the engine wouldn't start. I lifted the back seat to find an awful smell coming from the fuse box. I pulled the fuel pump fuse to find it singed. The vehicle will be needing a new fuse box and I'm still waiting to find the part.

I am a widow living alone on a fixed income. I have less than 80,000 miles on my vehicle. Long story short. Vehicle wouldn't start - had it towed to shop - they put it on machine - showed fuel pump was out - put in a new relay, fuel pump, etc. Did not solve problem. Found later that fuel box, relay fried, partially melted area on fuse box. Fire hazard. Ending up paying over $1000 for repairs. Have been told repeatedly that this has been an issue with this type car and there have been no recalls. Also told that probably will happen again. I cannot afford this. Please help. There are hundreds of similar complaints. Why doesn't someone do something about this dangerous and expensive issue.

The vehicle is leaking fuel down the sides of the gas tank and there is pooling of fuel around the fuel pump on the tank, also on this vehicle the exhaust pipe runs in the middle of the gas tank. The vehicle was taken to a repair shop and diagnosed with a leaking gas tank, after hearing that the vehicle was taken to the GM dealership and diagnosed. The GM dealership is stating that the gas tank is cracked. The vehicle has never been in a wreck! this is a serious safety issue and there should be an investigation on this matter, and I also think that it is the fuel lines going to the fuel pump that sits inside of the gas tank that are leaking, not a crack tank. Leaking or cracking fuel tanks on vehicle should be an automatic recall. Thank you for your time:
