2009 Buick Lucerne Electrical System Problems

The contact owns a 2009 Buick Lucerne. The contact stated that while attempting to start the vehicle, the engine failed to turn over. No warning light was illuminated. The contact stated that upon inspection he became aware that one of the relays from the electric fuel pump under the rear passenger’s seat needed to be replaced. The contact stated that the fuel pump relay prong base had melted due to overheating. In addition, the contact stated that the fuse was a 10.01 AMP instead of a 5 AMP which could have caused the failure. The local dealer was not contacted. The vehicle was repaired; however, the failure reoccurred 2 days later. The manufacturer was made not aware of the failure. The failure mileage was approximately 66,000.

The car died suddenly and would not start, with no warnings or codes. Towed it to a Midas repair shop and it was diagnosed as a corroded Low Profile Fuel Pump relay. This was replaced, and the car ran fine for 3 days before going dead in the middle of driving and left me stranded in an intersection. Had to get it towed back to Midas where it was more accurately diagnosed that the issue with the relay was being caused by a faulty Rear Electrical Center. Both of these parts have been recalled, and I have only owned this car for a little over a year. It has only around 40,000 miles on it. Despite this recall, upon taking the car to the local Buick dealership, they stated they could not cover the recall due to it being expired before I even owned the car. I do not understand how it is right or fair for this to have to be paid out of pocket, for $183.53 and $818.81 respectively, when it is not my fault, it is a faulty GM parts issue, and GM stated they will not stand behind their product and cover the recall despite the evident risk to my safety if I was to continue driving the car without repair. I understand it is expired, but I fail to see how this is ethical when the part is still faulty to the point of being dangerous.

Fuel Pump relay fuse is getting burnt up and not allowing car to start. This is a known problem and Nhtsa has already made a recall but mine isn’t recalled. You would think since mine is a 2008-2011 Buick Lucerne it would be able to get fixed. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2009 Buick Lucerne. The contact stated that while driving approximately 70 MPH, the fuel pump relay overheated and burned the fuse box. The accelerator pedal and steering wheel became inoperable. The contact was able to control the vehicle and park the vehicle. There were no warning lights illuminated. The contact replaced the relay, but the vehicle failed to start. The contact called the local dealer and was advised to schedule an appointment for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 170,000.

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 keeps burning out.

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 GM

failed fuel pump relay and melted fuse block. Car would not start in garage. Knew this vehicle is known to have this issue and when investigating the failure to start the first thing I checked was the fuel pump relay and fuse block and sure enough that was the issue. Common issue that Buick never addressed adequately.

Vehicle was no start. Dealer found fuel pump relay bad on 10/05/201. Next time using vehicle same problem. On 10/20/2021 dealer service department diagnosed bad fuse box. The fuse box is located under the rear passenger seat. It was extremely hot and melting. Fortunately no fire, this time.
