2008 Buick Lucerne: check engine light

Filed Sep 10, 2024 · Electrical, Fuel system · TX · fire

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.

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

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.

I took delivery of a 2008 buick lucerne.last year. Almost immediately I had problems. I proceeded under pa. Lemon law due to electrical issues (engine light indicating a problem) represented by counsel. I was told the problem was fixed and settled for a flat amount. Since that time I have had additional engine light issues but this time it has been diagnosed (and documented) as a problem completely different than that which occurred previously. The original problem was well in excess of five times and close to 30 days down time. This new problem is now on its second occurrence and now I am in rental car. I have informed gm and the dealer that this vehicle is an accident waiting to happen. It is a potential death trap. The dealer finally admits today that this vehicle is defective. However, gm has taken a position that the first incident was settled that they refuse to acknowledge that there is a new & second problem not fixed by the first recall. I have even offered to give them their settlement money back on the first occurrence I am so disgusted. The car is a danger not only to myself but to others that I am on the road with as a travel the pa tpk. Everyday for work. Gm refuses to listen to their dealer who now admits that this vehicle is defective and confirms a new and second problem. Gm will not listen to their dealer nor take this seriously. One problem solved another electrical problem (supposedly involving an emission systems breakdown) to go. Can someone at the agency please help me?
