I've had my FX for about 4 weeks now, and I have this extremely annoying whistle coming from the driver's side outside mirror at 65-70 mph. It sounds similar to the modem dial up wistle on your computer, only it never connects. If I put my hand on top of the mirror it stops. I do have paint protection film on the edge of my mirror, but the right mirror has identical film on it, and it doesn't whistle. Does anyone have or has anyone heard of a problem with this wind noise on the driver's outside mirror? I want to know if I should take it into the dealer for warranty service or if I should take it to my film installer to see if a new installation would stop the whistle. Thanks.
