Radio/tape Cd Player problems of the 2006 BMW X3

Electrical and has been affected since the car was less than 5 years old, radio would suddenly get loud if volume was adjusted. After the electrical issues started about 2 years later my a/c started having issues thought it may be a leak but now after seeing the recall on electrical issues on some models this SUV X3 should have been on the list but it's not, and should have reported this a long time ago that this is a lemon. The back window also slides down another electrical issue. Car was driven for pleasure every few days but has more issues than older cars.
