Call Ford customer service, phone number should be in your owners manual. Our 2015 ACE 30.1 had a problem with a power steering leak. I called Ford CS and explained the problem and they took care of it from there. Offered to tow it to a dealer, which was not necessary. They found the nearest dealer that could accomidate the MH, contacted them, explained the problem and that it was under warranty. All I had to do was call the dealer and set up an appointment, everything fixed at no charge and in a timley manner. Jim.
