NHTSA Complaint #11481899 — 2010 LINCOLN MKS

My car will intermittently (more times than not) lose its power steering assist, making it almost impossible for me to drive. I've had the car looked at, replaced the rack and pinion assembly, put on new tires, ran a diagnostic, and the car still lacks power steering most of the time. When starting the vehicle, the wheel will lock up, and the message "Power Steering Assist Fault" displays, no matter how many times I try to restart the car and allow the computer to reset, the fault does not go away. I rarely have times when I can drive with a power steering assist. The car has become a serious problem because I cannot get to work or school safely; when driving the other day, the power steering went out, and I was almost in an accident. I believe that there is a defect in the 2010 MKS, just like there was with the other years that were recalled, the fact that this issue has cost me so much money (and I cannot get out from under the car, I would if I could), and still puts me at risk for serious injury is seriously concerning.
