2017 Buick Encore Steering problems

Steering wheel locked up, had to replace rack and pinion, locking up when turning, therefore needing a wheel alignment.

The power steering works intermittent. In the morning when it is cold there is no power steering for you park it in the sun and let the inside of the car heat up it will start working. Also, when it is cold if you let it run with the heater going on the floor it will start working after some time. The dealer is saying the steering control module is bad. I have seen that buick has recalls for other models with the same issues.

The locking lever for the tilt/telescopic steering column will not stay locked the lever falls out of the locked position and the column collapses while driving I reported this to my servicing dealership over two weeks ago and have no indication they have ordered a replacement part

Car was parked on level ground outside home. Atv accidentally ran into rear bumper of car (had moved approximately 10 feet). Car rolled away and ended up rolling down a small hill, jumping a ditch and resting on another hill. Car moved approximately 300 feet prior to coming to a stop. Wheels were noted to be turning and rolling normally and car had minimal resistance to moving. Car was in park with secure break when we arrived at car.
