It happens on all vehicles, its rail dust/brake dust etc. It comes off with a clay bar and make sure to polish, seal, and wax the whole car.

It is normal, you mainly see it on white cars but it happens on all colours.

Come on Cold Weather! Get the hell outta here! My X is not liking it and neither am I! 2 effin degrees over here!

Old man Winter is layin the smack down on us...:rant:

Stop complaining, I would switch with you anyday!

It is -34F with the wind chill here this morning! :(

Oh Damn!!

From a cold start, how's the X run in those temps?

The x starts everytime, but just makes a funny noise ;) I know it doesn't like it.
Thank god it's in the garage overnight :D

Yeah mine makes that funny noise too...Everytime I hear it I cringe and hope nothing broke...The X definitely doesn't like it..

Me too, can't wait for spring to replace the door lock actuators!

what kind of slicone i can use i have the same problem with my x5,3.0,thank you?

As a new owner, I can tell you guys are scaring me. I'm beginning to wonder if we made a good decission buying this car. Well, its 7 degrees outside this morning, so wish me luck I guess...

Well, I need to say so far the antifreeze spray of the door mechanism does really work. Been 3 days of sub or near zero here, and my doors open flawlessly.

I guess I will wait till it gets back in the 20's before I take it through the wash though.
