There are 8 owner-reported steering complaints for the 2012 Lincoln MKSin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I’ve owned my 2012 Lincoln MKS for 3 years. A warning recently appeared saying “Power Steering Assist Fault,” and now the steering is very hard to turn, especially at low speeds. I’ve already paid around $1,800 in the past to fix this issue once, but now I’m experiencing the same or similar problems again. I haven’t had it officially diagnosed this time because both Ford and the dealer told me it wouldn’t be covered, since the recall (15S18) is now expired. This is a serious safety issue. The car is difficult to control and unsafe to drive. I’m a full-time worker and a father of two toddlers, and I’m still making payments on this car that I now can’t safely use — or only for short trips while constantly worrying about steering failure. I just found out about this old recall, and the dealership never told me anything about it when I bought the car used. I strongly believe I’m experiencing the same issue Ford previously recalled these vehicles for, and I’m asking NHTSA to investigate or reopen the recall so it can be repaired before me or my family is seriously injured.
