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.

ABS light and stability control light on. So I have no ABS function of the brakes. Had front wheel bearing replaced but didn't fix the issue. ABS and traction control module light still on.

The contact owns a 2011 Buick Lucerne. The contact stated that the front driver's side brake line was fractured. The contact noticed the failure while his wife was reversing out of a parking space with the brake pedal depressed. The contact stated that the brake pedal went to the floorboard. The contact added brake fluid to the vehicle and drove to his destination. The vehicle was later taken to an independent mechanic where the technician saw brake fluid leaking from the brake line. The vehicle was diagnosed and the contact was informed that the brake hose needed to be replaced. The vehicle was repaired. The vehicle was not taken to a dealer. The contact mention that the passenger side brake hose showed evidence of a fracture. The manufacturer was not made aware of the failure. The failure mileage was approximately 102,465.

Brake line experienced a catastrophic failure resulting in a rapid loss of all brake fluid and complete loss of brakes while on a city street. Car was towed to the repair shop where it was determined that all brake lines were severely rusted from the outside and one had failed. This car was always garage kept and very infrequently driven on salted streets. All brake had to be replaced. I think it is unreasonable that brake lines should rust out and cause such a failure. Someone could have been killed. A person does not think of their brake lines as requiring constant inspection, like one might keep an eye on the tread on their tires.
