2009 Buick Lucerne: won't start

Filed Aug 1, 2024 · Electrical, Fuel system · SC

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.

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.

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.

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.

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.
