Lose Power Steering problems of the 2012 Buick Lacrosse

Tl the contact owns a 2012 Buick Lacrosse. The contact stated that the vehicle was taken to unknown dealer in 2014 to be serviced under NHTSA campaign number: 13v173000 (electrical system); however; the repair did not correct the failure. The contact stated that while reversing, the vehicle stalled and all lights on the instrumental panel flickered and the battery warning light illuminated. The contact also advised that the steering wheel lost power steering ability while driving. The vehicle was not taken back to the dealer to have a diagnostic performed. The vehicle was not repaired. The manufacturer was notified. The VIN was not available. The failure mileage was 45,000. Li.

Car stalled out twice, lost power steering. I was backing out of a parking lot space; restarted and then stalled while pulling onto street. Fear is it stalling in traffic and getting rear-ended. I took to garner Buick where had purchased new. When car was relatively new and still on warranty had had similar issue, but dealer never found problem. Now occurs again. They found two sensors that failed but ok now so told me to drive over weekend and see what happens. I see this as a big safety problem and an accident waiting to happen. Buick should be responsible if this happens, but in the meantime I am the one injured.

Vehicle was excessively rough in transition between hybrid and engine power and would jerk as if someone had placed the vehicle into park while moving. Vehicle lost electrical power to ac, radio and other accessories. Vehicle shutoff and had to be stopped and placed into park before it would restart. Vehicle lost power steering and the steering would stay locked in position until the vehicle rolled about 10-15 feet or until the vehicle transitioned to engine power. These condition repeated multiple times in a two day span, the vehicle was taken to the dealer for service. The dealer replaced a solenoid and an engine mount stating they had excessive wear. The vehicle now stays running, but I continue to have issues with the rough transition between modes. My concern is that this is the root cause of the excessive wear on the other parts and that the vehicle shutdown and steering loss will occur again. If it does, the damage to property, injury, or loss of life could easily occur given the lack of drivability and loss of control of the vehicle when the condition occurs.
