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.
New Buick Lucerne does not have room for a size 12 shoe to properly operate the brake pedal. The dealer says that the panel under the dashboard is in the correct position. The problem was not corrected. At times, the situation prevents proper application of the brakes.
