Warnings problems of the 2014 Lincoln MKZ

The steering wheel locked up while I was driving. A message on the screen said power steering assist fault. I could not turn left or right and the brake was very difficult to press.

12m02 -- I took the vehicle in for this extended service plan twice during while it was still active. Both times the dealership tried to play it off as "not under the warranty" and "software issue not hardware". They even charged me for the service over $250 worth of "updates". That did not even fix the issue with the display turing off while the vehicle is operating making most of the vehicles functions useless. The dealership is now denying to fix the problem and Ford/Lincoln is claiming it is out of warranty. When I took it in already twice for this issue and was taken advantage of and robbed $250 when they should have replaced the display (apm module) to fix the issue as per forda instructions. Please help me as the apm module would cost me over $2,000 to fix when the dealership and Ford should have fixed it in the first place. As they are ones who messed up and not me neglecting to take the vehicle in to them and inform them of the issue. I even had the vehicle with them when the problem was showing of the display turing completely black for over 5 minutes. Then coming back and just stuck in a boot cycle where it turns on and off constantly until the vehicle is turned off. But then it still has an issue later on even after the restart of the vehicle.

The problem with this car is that the backup camera stopped working on my car. The line are gone and the image is reversed. The dealing told me it was the camera and it was almost $1,000 to replace it. I did notdo it, but now I am finding many othes with the same broplem. The safety issue is that when I back up and I am not sure if what I am seeing is accurate.
