For some unknown reasons my windows go down while Driving , Sometimes they may work fine, then out of Know where all all 4 Windows go Down at any Time , came be Very Dangerous in a Rain Storm or Huracane , i have taken my Car to atleasat 2-3 Shops they Pretend to repair it and said they needed a better Scanner.
While driving my windows go down when driving without a notice, this can be safety issue when I'm driving, also can be a distraction far as safety goes, this happens often without notice and allows the rain to enter inside my vehicle.
With the key on and the vehicle turned off, in park, parking brake on, pressed closure button. During closure headrests began to raise. Not a sudden pop up kind of raising, but a slow, steady raising, as if I had my hand on the button to raise them, yet I did not.
Opened door and got in car to close and pulling handle the handle broke off. Went to mercedes to order part and they said it was a weak part and have to order from germany.
