I have my charge timer set to start at 23:15 PM and shot off at 7:00 AM to take advantage of the low nightime rate for charging. Yesterday I took the car to a manual car wash. I locked the car before I started washing. While washing I noticed the lights flashed once. When I "started" the car, the touch screen panel was blank for a moment and a warning message that unfortunately I did not pay much attention to as I was in traffic. Drove 1 block and went into the grocery store. When I restarted all seemed well except that the audio switched from ipod to a mystery FM radio station. Later when I plugged the car in it started charging immediately. I checked the charge timer and if was off.
