Ford are well aware of this issue, and under consumer law dealerships are supposed to do what is a very quick fix free of charge. Now getting them to acknowledge that might be another story. However if enough people told Ford dealers that consumer law states if something on a vehicle is a known fault, making the faulty item not fit for purpose, even when out of warranty, it must be rectified. It is not rocket science for Ford to fix this problem they well and truelly know about. There is apparently a firmware update as well, which the ethical dealers also will do free of charge, that will prevent frozen screens from happening again. There is nothing wrong with politely informing any dealership of your consumer rights, if they want to be difficult.
