After restarting the car after a continuous drive of 2 or more hours the screen goes blank and the radio and heater controls don't work. the radio volume and heater resume where they were before the car was turned off. After a few minutes, restarting the car restores the screen & controls. It's apparent that the computer reboots itself.
The dealer has no clue because the problem can't be recreated at the dealership. This has happened several times and before buying the vehicle at the end of the lease I'd like to verify that this isn't going to become a larger issue. Aside from this concern, the Journey has been outstanding.

 

This happened to my R/T RB5 on two separate occasions. Have not had any touchscreen problems aside from those two occurances.

Peace.
