Fuse box (rear) 2008 Buick Lucerne CXL. FUEL PUMP Relay burns fuses out quickly. The fuse box located under the back seat has been having issues of burning where the fuel pump relay is located. It then in turn shorts out the fuse box which keeps needing to be replaced. This is a safety issue as it catches fire under the back seat. Fuse box has been replaced before and continues to have issues and melts, causing the vehicle to die in mid traffic, does at stop lights or even just parked and running it dies out and smells like burning plastic. The fuse box has caught fire several times. The issue has been confirmed by several mechanics and dealerships. Also there is a history of electrical problems with the rear fuse box in carfax. There was no warning, and now the check engine light is illuminated. We bought the vehicle last year in June of 2024. There seem to be no problems at the time until shortly after we had bought the vehicle. Turns out there's a long history of electrical problems involving the rear fuse box with this vehicle. I have uploaded screenshots of the car report on this vehicle. There are more complaints.

What owners say
Several malfunction indicator lights in dash appeared suddenly. Car would not start after shutting off. Finally started and drove to repair shop. Diagnosed as faulty ride height sensor. Shop searched for part at several dealers and online and found the part was discontinued in 2021. I contacted Buick and was offered $1500 off on a new GM car. I have not received any suggestions on how to repair the car or remove malfunction indicator lights which I specifically asked for. The repair shop is waiting for me to find the part and I have not been able to find one. Dealers have no answer and neither does Buick. The repair shop says it will start if sensor is unplugged but suspension will not work and dash will still have malfunction indicator lights. It is my opinion to operate under these conditions, it would definitely be hazardous.
The contact owns a 2008 Buick Lucerne. The contact stated while attempting to start the vehicle, the vehicle made an abnormal sound and failed to start. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic. The vehicle had not been diagnosed or repaired. The contact referred to the federal safety agency Campaign Number: 08V441000 (Electrical System). The manufacturer was not made aware of the failure. The failure mileage was unknown.
I have a 2006 buick lucerne that loses power randomly as I'm driving whether its pulling outbjnto traffic, which could cause injuries possibly even death, or maintain a certain speed for any amount of time , it just randomly loses power and wont go for however long until it starts to accelerate again . Also if I'm at a red light or stopped waiting to pull out somewhere , although I have my foot on the break, my car begins to accelerate and almost pulling me out into traffic. I have a service engine light and the code reads h02s heating control circuit sensor but I've yet to have it inspected because there isn't a recall for my car on that problem even though I've heard and read many complaints with the same or similar issues
To start things off the car would crank but not start. My wife did some research and these cars have a problem with the fuel pump relay shorting out. So I replaced it and it fixed the problem for a few days. I was driving home from work and the car shut off. I could smell plastic burning. I pulled over and pulled the fuse box cover off which is located under the rear seat and I pulled the relay out and burned my fingers in the process. So something is wrong and it's causing the relay to overheat and melt. There are many people according to carcomplaints.com that have the same issue. I've seen a lot of people saying that GM says that the seat bracket touches the fuse box putting pressure on the relay causing this problem. Well after I replaced the relay I did not put the rear seat on and it still burned out. In my mind it seems to be a fire safety hazard. No check engine lights came on either.
The engine it's shutting off while driving, and after it gets cold it will restart, but after driving again another few miles it will shut off again. There are no lights on, so no mechanic to tell me what the problem is. I even called the dealer, and I was told that they can't diagnose the car because is no check engine light on.. I tried few different auto shops with no answer, so my car is parked in the driveway because I'm scared to drive it, I don't know how or when the engine will stop.. Another mechanic told me to drop the car to his shop but it make 2 weeks of work to find out the problem and I will have to pay for 2 weeks, and than to pay to fix it. It usually stops while in motion when close to the a traffic light, when I make a turn and always when I slow down
Car drains my battery and it messed up my alternator. I replaced both and once again my battery keeps being drained. I took it to the shop and the mechanic ran a diagnostic test and about 10 codes popped up saying electrical problem. Other models of this buick has been recalled for the same electrical problem. Il drive my car and it will completely cut off on me and the check engine light comes on. Il find my paper work from the mechanic if needed. This has been happening for months now. It didnt happen just once. So I cant drive the car until its fixed.
My 2009 buick lucerne wouldn't start..thought it was the fuel pump had it checked out..the fuel pump was good so we check the relay fuse and it was burnt out. I put a new relay fuse in and drove around the block my check engine light went on..so we rechecked the relay fuse and it was burnt out again..there should be a recall on the relay and fuse box.this could start a fire..I have 3 small children I need my car but at the same time I need it safe..I looked online and about 10 or more people are having this same problem..please recall these parts..
The car was garaged and hardly driven by the previous owner, and the current mileage is about 43,000. Since the beginning of my ownership the check engine light comes and goes randomly. The car also says on the digital readout "service air bag," pretty much all the time. I have had three different mechanics scan for the error codes and they could find nothing for them to recommend a next step. While I was in white plains, ny, I got a notice for an air bag service recall from the dealer. All they did was to put an insert onto my ignition key after a two hour wait. When I asked what this had to do with the check air bag light, they said, "if you drive with a heavily loaded key chain the pulls down, the service air bag/check engine lights erroneously come on." it was the most stupid thing I have ever heard, and I can't believe the federal safety agency would have allowed this sham to pass as a recall. Having read the bulletin board of complaints I see a number of complaints about air bags not deploying after an accident. You need to put out a recall---a real recall--on this vehicle for the air bag. Please feel free to contact me.
Driving down highway and vehicle stalled for no reason. Engine light did not come on. Attempted to start, but nothing happened...no click, no crank, nothing. Had to wait 10 min. Until key start attempt did anything and then ran fine. Have been driving in town ~35mph as well as slower speeds and vehicle will do the same thing...stall. Attempted to start, but nothing happened...no click, no crank, nothing. Had to wait 10 min. Until key start attempt did anything and then ran fine. This has happened approximately 12 times in the last 2 months. The gm recall (solution was a key insert) has been performed and this issue has occurred before and after the recall fix.
