“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.”

“Outer mirror, driver's side, turns down when placed in reverse and will stay in the down position. Occasionally it will turn down on its own when changing from park. When going to drive, there is no way to see oncoming traffic on the left without turning head and looking: something a driver isn't expecting. This always occurs going from stationary to motion. Occurance in random.”
