There is a problem with the heating controls. The temperature will be set at 72 and is stable for awhile, even days, then will spontaneously heat until it’s unbearably hot. This is a huge distraction while driving to having to keep messing with the controls. Safety issue! After numerous complaints to Ford’s service department with no results as the technicians cannot duplicate issue and there are no codes. Purchased a thermal imaging camera: 97.8 dash vents, 55.1 at knees and 80 degrees at feet (driver’s side). This is not a situation where the heating system is just trying to bring the cab up to temperature as this occurs when the truck has already been on the road for over an hour at a comfortable temperature and then it just erratically starts spewing out unbearable temperatures. I have thermal imaging pictures as high as 153 degrees Fahrenheit while the set temperature is 70. Something definitely wrong. I am submitting this complaint as I am tired of turning the truck in for repairs. Maybe if enough people say something, Ford will do something.
