One problem related to radio/tape cd player has been reported for the 2014 Tesla Model S. The most recently reported issues are listed below.
Touchscreen failure due to emmc chip. This rendered many of the vehicle functions useless, such as ac, turn signals, high-beams, radio, navigation, back up camera, proximity sensors, garage door opener, infotainment info, and charging. I was told by a Tesla service center rep that if battery fail do to not being able to charge it would be on me. Even though that function was rendered useless due to the screen failure. The car was parked in the garage while charging when this happened, I woke up to a black screen the next morning.
