Found a red-header "Take car for service" at the top of the display this morning, plus a range charge warning popup. Could not get rid of either, nor bring up control screen etc. iPhone App commands worked OK. Rebooted twice, still came up with the frozen display. Took in to Seattle service center, they got same result. They updated to latest OS (I already had .21), still got the frozen screen. So they replaced the touchscreen. And washed the car. Anyone else?
