I just got my X5 this past weekend and already experienced it.... first thing I did ... well after getting out of the car was doing a search. I had my local car shop spray some lubricant on it and it has been fine since then.

I am curious .. that if you get those air/rain deflector vents if that will stop or deflect some of the water that goes down into the door locks.. at least from the top portion of the door, this is something I plan to put on anyways but just got myself curious on this.
