Radio will change automatically by itself from radio to other source cd, change to sat and eject a cd without touching anything. Lexus couldn't find anything wrong when taken in. They updated the firmware, but it still continues to change from radio to sat and ejects cd's. I asked if there was a recall or other know complaints about this. I was told no by Lexus. I searched online and I find this happens to other customers so I wanted to document this defect.

Purchased a 2010 Lexus 450H in August of 2009 and less than one week after purchased my wife parked the car for two hours and returned and the battery was dead. Lexus sent someone to jump start it and we brought to service at the dealer in carlsbad, ca. The next day. They checked it over and said that the onboard computer never found a problem and that all appeared to be perfect. They doubted that the car was ever jump started but then called the towing people and found that to be true. They gave me a readout showing the car was fine and that the onboard computer showed no error.
