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.

The car would not start when I attempted to start it to go to work and had to be towed in for repairs. The fuel pump was found to need to be replaced. One week later the car again would not start and had to be towed for repairs. The problem this time was the rear fuse box that was shorted out due to the bracket rubbing against it, which seems to be a common problem for this model. A recall seems to be indicated because of this.

On 9/1/18 I drove my car all morning late that night when I went to drive again it wouldn't start and I could smell a little burning. Checked the fuse box and it had blew out a couple of fuses so we changed them. 3days later it did the same thing we changed the fuses again and once again the blew now when we changed them it won't start at all. I had to keep changing the fuel pump fuse and a dealer said it was because of the metal of the seat touching the box .

On march 28th, 2018 my vehicle a 2011 buick lucerne with 162,554 miles on it, would not restart after making a twenty-mile trip to take my grandchildren to school. I parked on the side of the road in front of my mother's house to visit, and upon my attempt to leave, the vehicle would not start. There were no warning indicators, strange noises, or smells that would lead me to believe the fuse box failure, leading to the box melting. When a battery goes bad, it smells like spoiled eggs, however in the case of my vehicles fuse box melting there was no toxic smell(s), that is a good thing since no passengers suffered from melting plastic fumes, I guess. I took my 2011 buick lucerne to the dealer's ship because my vehicle would not start. Upon the tech diagnoses the fuse relay had melted, and this was one reason the fuel pump was not receiving power to send fuel to the engine. My next concern is the placement of these components in the vehicle, they are located under the rear passenger seats. If the voltage, fuse box melts again soon, the possibility of an internal fire is highly possible and thus the loss of lives is likely. After conducting my own online search, this is a problem that has been overlooked in the past or minimized in order of importance for the consumers safety concerns reported at various dealerships.
