Very infrequently, the TPMS light will come on and flash saying there is a problem with the tire pressure monitoring system. I had it checked by the dealer and they said there was no problem. Also there was a time when I was driving down the road (in very hot weather) and the radio and climate control turned off and back on for a second as I was coming to a stop. I only noticed this because when it turned back on, it went on a different radio station, and much quieter than before.

Kind of strange, but I don't really suspect anything.
