Tri-State Ford Lincoln in Maryville, MO, has an excellent, competent Service Department and Personnel. The AM Radio on my 2013 Lincoln MKS had poor AM reception from the time of purchase in May 2012. Numerous visits to my local dealership did not fix the AM reception problem, despite the replacement of the radio, electrical wiring harness, and module(s). Two and a half years later, the AM radio was fixed after working with a Lincoln Representative who made an appointment for me to get a second opinion at Tri-State Ford Lincoln in Maryville, MO. The Tri-State Service Manager, Steve Schons, listened to my description of the AM radio reception problem and directed his best Technician to find the cause. At the end of the day, the Technician had diagnosed the problem was due to faulty wiring but needed another day to disassemble the dashboard panel to trace and find the faulty wiring. Because they needed to keep my car another day or two, Mr. Schons provided me a new Lincoln MKZ to drive while they fixed my AM radio. The next day, Mr. Schons called and told me they had fixed the AM radio reception which was caused by a broken wire. Needless to say, I am delighted to finally have a working Am radio. I highly recommend the Service Department and Personnel at Tri-State Lincoln in Maryville, MO.
