On February of 2013 while I was backing out of a parking lot, the rear windshield wiper started by itself and sprayed all the wash fluid until the tank drained and kept making a loud noise (audible from inside and outside of the car) even after I turned off the car engine. I took the car to a dealer and I was told the problem is due to faulty junction box. It took them two weeks to get a new junction box & replace it. After one year, on February 7 2014, the same problem occurred but this time it is the front windshield wiper that started by itself, drained the wash fluid tank and kept making a loud noise. Took the car to a dealer the same day & I'm still waiting for my car to be fixed. I was told BMW is aware of the problem with the junction box with X3 cars and yet they don't notify owners and replace the faulty junction box until after the problem occurs (it usually takes more than a week to get a replacement junction box). In my opinion this could be a safety issue; for instance if the wash fluid tank is drained while the car is being driven in a bad weather day ( such as heavy snow) which requires to frequently clean the windshield, it prevents the drivers ability to clean the windshield and could impair his/ her vision and could lead to an accident. BMW should recall all affected cars and replace the junction box before someone get injured.
