2011 Buick Lucerne problems

“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.”

“TL* THE CONTACT OWNS A 2011 BUICK LUCERNE. THE CONTACT STATED THAT THE CRUISE CONTROL WOULD ACTIVATE AT RANDOM. THE VEHICLE WAS TAKEN TO THE DEALER SEVERAL TIMES, BUT THEY WERE NOT ABLE TO REPLICATE THE FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS NOT AVAILABLE.”

“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.”

“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.”

“TL* THE CONTACT OWNS A 2011 BUICK LUCERNE. WHILE DRIVING 60 MPH, THE ENGINE STALLED AND THE STEERING WHEEL SEIZED WITHOUT WARNING. IT TOOK THE CONTACT SEVERAL MINUTES TO RESTART THE VEHICLE. THE FAILURE OCCURRED ON SEVERAL OCCASIONS AND, EACH TIME THE VEHICLE STALLED, THE CONTACT WAS LOCKED INSIDE THE VEHICLE DUE TO THE ELECTRONIC LOCK SYSTEM WITHIN THE VEHICLE. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE CONTACT SERVICED THE VEHICLE HIMSELF AND FOUND THAT THE WIRING HARNESS HAD MELTED AND THE ENGINE WARNING INDICATOR ILLUMINATED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 118,000.”

“TL* THE CONTACT OWNS A 2011 BUICK LUCERNE. WHILE DRIVING AT A LOW SPEED, THE VEHICLE HESITATED WHEN THE BRAKE PEDAL WAS DEPRESSED. THE CONTACT STATED THAT THE TRANSMISSION WAS NOT IN SYNC WITH THE ENGINE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE TRANSMISSION FAILED DUE TO EXCESSIVE TRAVEL IN THE THIRD CLUTCH PISTON. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WOULD NOT REPAIR THE VEHICLE BECAUSE THE WARRANTY EXPIRED. THE FAILURE MILEAGE WAS 117,000.”
