I had the same message on my 2011 MKS. The first dealership tried to tell me it was a security module that would need to be replaced because they couldn't get the computer to go into diagnostic mode. I declined the service and took the car to another dealership. They diagnosed which sensor needed to be replaced in minutes. Unfortunately, when I returned to pick the car up, I was given a bill for the service. I argued that the car was still under the bumper-to-bumper warranty and they said the TPMS was not covered because it is a tire-related part. I reluctantly paid and began researching the warranty coverage when I arrived home that evening. After sending an email to Lincoln service, they confirmed that the part was, in fact, covered. From there on, Lincoln took great care of me. They contacted the dealership and I had the refund check in my hands within a couple of days. It was roughly $85 for the part and labor.
