 Lost wiper in heavy rain storm,  one of the windows insisted to open on the freeway and flooded my car.  The next day it magically cured itself.  Alarm goes off on its own.  I have observed this myself.  Nothing passed by my X5 with loud music or exhaust.  MY dealer cant figure it out.  The battery is excellent.  Lost the driver's memory seat, fixed it then it was the passenger's memory seat.  What's next?  When the car goes over a bump, the rear wiper and washer are on.  You all get the idea...
