2011 Buick Lucerne Complaints

Vehicle purchased used through Carvana. Battery installed at purchase was approximately 10 years old and later failed, causing starting issues and an instance of power loss while driving that left the vehicle stranded. Battery has been replaced and original battery retained.

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...

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.

The contact owns a 2011 Buick Lucerne. The contact stated that while using the front driver's side interior door handle to exit the vehicle, there was an abnormal cracking sound coming from the door. The contact stated that the failure had occurred on several occasions. The vehicle was taken to an independent mechanic, where the front driver's side door handle was replaced approximately 4-5 times. The vehicle was recently repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 28,000.

Passenger rear tire blew out the side wall all around the tire. The dealer that installed the tire has it for warranty. It was an large noise and I was able to pull to the side of the road immediately without loosing control. Yes the problem was reported to the dealer that put the new Falken tires on my car in September of 2025. The tires only had about 2,000 miles. My tire has tire pressure monitors on it, they did not alert me to a low tire pressure. I do have a few pictures of the tire showing the whole side wall blew out all around the tire. I am concerned for the safety of my family and anyone else that has this tire. I still have 4 of these tires on my car and I am worried that if another one blew out, it could end up in a serious crash.
