I am enjoying my new Ford Escape Titanium most of the time, but about once per week, the touch screen doesn't start up when the engine is turned on. It just stays black and doesn't respond to touch. Other controls such as volume, fan speed, etc, which are manual, work but the controls for temperature, audio, navigation, clock can't be used. There seems to be no obvious pattern of time of day, temperature, etc that is associated with the fault. Once it happens, it is not easy to reset quickly. Turning the engine off then on again doesn't fix the problem. Once the engine is off for some time, the screen comes on as it should when the car is started.. The first time I took the car to the dealership to resolve the problem, they could not replicate the fault so did nothing to correct it. The second time, the system was rebooted. The third time, the software was updated. The problem persists. The car is at the dealership again now. The technicians appear to be baffled.
