2011 Buick Lucerne Lafayette, GA

ELECTRICAL SYSTEM

The vehicle’s instrument cluster appears to be a non-original unit that may not be correct for the model year. The cluster is responsible for displaying the odometer and communicating with other vehicle systems. After purchase, I observed that diagnostic scan tools could not consistently access or communicate with multiple modules, and an experienced mechanic indicated the instrument cluster may be incompatible with the vehicle’s configuration. Because the odometer reading is displayed through this component, there is concern that the mileage may not be independently verifiable. The vehicle otherwise operates, but diagnostic communication inconsistencies raise questions about the reliability of system-level data. Additionally, there does not appear to be any service documentation indicating that the instrument cluster or odometer system was replaced, repaired, or recalibrated. This creates uncertainty regarding how the current mileage reading was established. The inability to fully verify mileage and system data may affect maintenance accuracy, resale valuation, and overall confidence in vehicle information.

2011 Buick Lucerne Pahrump, NV

ELECTRICAL SYSTEM

Fuel pump relay is overheating to dangerously high temperatures. At least 211 F degrees. Causes the fuel pump fuse to melt leaving me stranded. Immediate replacement of the 20 AMP fuse is necessary to get the car running again. The fuel pump relay gets really hot even if the AC is not on. Waited for hour and a half in near 100 F degree heat for a tow truck to it home. I’m lucky the car did not catch on fire. I know quite a few of the Buick Lucerne’s have had recalls regarding this item. Picture of the actual car is included. No police report was necessary as this was a breakdown situation. This has utterly disrupted my life because I do not have access to a car with good air conditioning until this problem is repaired.

2010 Buick Lucerne Buchanan, MI

ELECTRICAL SYSTEM

We have a Buick Lucerne 2010. We went out it would not start. Tow it to dealership they replace the fuel pump. We did. Get it home next day it will not start again. Tow it to dealership again. This time they find melted wire connectors. Under back seat and on a fuse box.They replace them it starts and melt them again. This time they call to junk yards to get a used fuse box and connectors. Because of cost. The junk yards did tell them it's a known problem with these cars and they sell these fuse boxes and connectors sell as fast as they get them. We said no used parts on this car. Come to find out that GM now's about this problem. And has not done anything about it. They meaning GM. Has even put out papers on the internet as how to try and fix it. Such as cut the insulation around the fuse box.And even cutting the seat belt bracket. My wife drives this car everyday. Now she is afraid of it. Because if it happened once could it happen again. I don't now. I have drove GM's all my life but am not happy about this. What do I do. Please help. I am a retired firefighter and I do not want her to drive this car if it could catch fire.

2008 Buick Lucerne Fontana, CA Fire

ELECTRICAL SYSTEM

I purchased the vehicle a week before the incident. There were no warning lights or messages and nothing to indicate there was a problem. I was driving in a crowded parking lot so I was going very slow. When I turned my car suddenly died. My husband was passenger and my daughter and 2 sons were in the back. Smoke started coming from the seat and we all rushed out of the car while the seat was on fire. my husband pulled the seat out and put the fire out. I was not aware the battery is located under the back seat. I had the car towed and inspected by a mechanic. I was told the battery does not have a cover so the metal from the seat was touching the battery causing the fire. The battery is a top post battery that is recommended for this vehicle. I can find no information about a battery cover. The vehicle is available for inspection. I have photos and the report from the mechanic but I'm having trouble uploading them

2008 Buick Lucerne Houston, TX Fire

ELECTRICAL SYSTEM

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.

2006 Buick Lucerne Coshocton, OH

ELECTRICAL SYSTEM

The airbag lights on and there is an electrical issue also that causes the car to smoke and nearly catch fire, as soon as the battery is reconnected. Therefore rendering it non drivable. It's the same problems that are associated with the 2006 Lucern,s. When i look up the year make and model it says there should be a recall but once you put in the vin it nothing comes up.The vehicle is readily available upon request but has not been inspected by anyone else.

2009 Buick Lucerne Spartanburg, SC

ELECTRICAL SYSTEM

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.

2011 Buick Lucerne Canton, IL

ELECTRICAL SYSTEM

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.

2008 Buick Lucerne Laveen, AZ

ELECTRICAL SYSTEM

Our Buick Lucerne would crank but wouldn't turn over when trying to start after trying to pick up take out. 1) It was suggested to me by a passerby that it sounds like a fuel pump relay. 2)I started to smell something burning. The passerby who happens to be familiar with Buick Lucerne tried to help. He lifted the back seat and showed me the fuel pump relay which was burned. Then he switched the electrick window relay which is the exact same relay switch and the car started. Went immediately to an autozone and bought spare fuel pump relay. Thought that solve the problem, but every 2 to 3 days I'd smell that burning smell. 3) The mechanic I've been going to for 10 years confirmed the issue 4)Have not taken to dealer or insurance rep 5)Absolutely no visual warning on dashboard. the warning happens when I start smelling the burning odor. Started one and a half months ago....

2009 Buick Lucerne Clarks Grove, MN

ELECTRICAL SYSTEM

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)

2008 Buick Lucerne Salyersville, KY Fire

ELECTRICAL SYSTEM

The transmission started not shifting as I was driving down the road and the relay fuse box caught on fire and I think it’s where the back seat lays on top of the fuse box which rubs the fuses. Which is dangerous bc it catches on fire and could blow the car up while driving
