Lose Power Steering problems of the 2016 Ford Fusion

While driving on the highway to work my steering suddenly locked up and jerked and then I got multiple alerts and lost power steering. The alerts were "service advancetrac" "steering assist fault service required" "hill assist not working" "service battery charging system" and there were two traction control lights. After work the traction control lights and alerts were still on and I did not have power steering on the drive home.

While driving on a straightaway going 70 km, all dash lights and indicators came on and I lost power steering.

This vehicle is at 48800 miles and I started to receive the following warnings/errors on my dashboard when the problems began: "hill hold assist not available", "service advancetrack", abs fault and airbag failure sign lights remain while I was driving the car. After these warnings I lost power steering assist and pulled over and restarted the car. However the warning signs did not clear and I lost abs, traction control and airbags. I have contacted with a Ford dealer to diagnose the problem. Error codes they got from the car were c0031 and u0401. The first one is related to a short wire in the abs wheel speed sensor at the driver side front wheel and this part was replaced at the dealer. However, after replacement all the mentioned warnings/errors remain and u0401 code remained. Dealer does not know whether these are just from communication error from the computer or these parts are actually defective. I am not able to use the car right now. In any case, all of the affected systems are not related with drivers driving habits, storage conditions and other things related to the usage of the car and seems like a manufacturing problem, even if it is a communication error or wiring problem. And the affected components are vital so if there is a production error, this should be resolved as soon as possible.
