There is an issue with the dash of this vehicle. The dash AC button does not work at all, and the pre collision is not working either. The Ford dealerships local to me refuse to even look at it, even though there is a recall on this exact issue, put out by Ford. Recall 22S65. Getting Ford to do anything for you is a joke. There is one dealer in the entire state that works on Ford chassis rv's and they are refusing to even take appointments at this time.

IN ADDITION, THE FRONT PASSENGER SIDE WINDOW GLASS FELL OUT OF THE WINDOW FRAME. THE VEHICLE WAS NOT TAKEN TO A DEALER OR INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING OF THE FAILURES. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES AND DID NOT ASSIST. THE APPROXIMATE FAILURE MILEAGE WAS 375.
While driving at highway speeds (70 mph+/-), my diesel powered vehicle 'derated' (I believe that is the term) for no apparent reason. An engine light came on related to a DEF system malfunction. I can provide the code later. My vehicle instantly went from 70 mph to 15 mph on a crowded interstate, on an inside lane. With some difficulty I managed to make across three lanes to the shoulder and turned off the vehicle. After a quick inspection, finding nothing obvious, I proceeded down the shoulder to a gas station. I tried to top off my DEF tank, …
