I have a 2009 Prius with 65,000 miles and have recently noticed sensitivity trouble with the touch screen. At times it will not react to my button presses and other times if I touch one part of the screen the touch will be registered in another area of the screen. Usually I turn the screen off (if I am able to get the touch of the off button to register) and restart later. It's possible that this could be due to the heat in New Mexico but I haven't experienced this problem in the summer time before (I am the original owner). Has anyone experienced something similar?
