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 This is the second time in 5 years fuse box has been replaced by certified dealership.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

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.

Vehicle stalls out without warning. Unable to start. Burning smell under rear seat (driver side). Service bulletin issued by GM #15-na-051 (July 26, 2016). Design defect causing no start/stalling condition because rear seat bottom bracket pressing on fuel pump relay causing fuel pump relay to short out (burn out). This is a safety issue which could cause serious injury or death by causing an accident when car stalls out without warning. GM refuses to issue recall. GM says to take vehicle to local dealer and have repair/modification done at owners expense.

Car was fine 1 day next day would not start. Had it towed mechanic replaced fuel pump and relay. Next day I'm driving going down hill and it looses all power and won't start. Had it towed again. Mechanic replaced relay. Picked car up and drove it for about 2 hours and relay burned out in middle of intersection. Walked to parts store and bought relay. Replaced and drove home. Next day going to work and relay burns out again. It is super hot and melts plastic around the hole in fuse box where the prong goes in. Have replaced it several more times and I am now taking it back to mechanic before it catches on fire or gets me killed driving down the road. This is a major problem with the Buick Lucerne. I once trusted this vehicle. Please please please recall and fix this problem. Stranded every time I leave the house.

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 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 NHTSA 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.

Fuel pump relay burns out and is so hot to the touch it will burn your hand. Was found when the car would not start. Has happened twice now, a week apart, and on the second occurrence the fuel pump was replaced by the mechanic to rule out a possible short causing the issue. The relay is still getting hot so much so that the seat gets hot and I fear it will catch on fire. The mechanic is going to look at the fuse block to see if there is corrosion or damaged wiring causing the issue. The relay was hot when the car was running, and just hadn't cooled by the time it was found. This speaks for how hot it was getting as it burned the mechanic when it had been sitting a few minutes. It does cool down after a while so it is not heating up while stationary.

Crank, but no start. Fuel pump relay pin melted into fuse block (under rear seat). Replaced fuel pump relay, with same result: No start melted the 4th pin in relay and plastic on fuel block creating an obvious fire hazard, that close to the fuel tank, under rear seat.

The vehicle was towed to patriot auto sales (12100 lorain ave, cleveland, oh 44111) where it was diagnosed that the fuel pump relay switch needed to be replaced.

Car would turn over will not start. Mechanic said that fuse under seat over heated. Purchased with 95K 7 days ago. After researching this is aknow issue for this model. I have it towed to a dealer I see fuel pump may need to be replaced as well. Will it take a fire or a highway accident before Buick has to uwn up to this dangerous problem. I am sure you are aware of the problems with this model. Car was staitionary but what can prevent this happening to the owners drivng in motion.
