My favorite fix thus far...
 

Yes... I have swapped out wiper blades and the like... but nothing (bang for buck wise) makes a car feel more complete than when the car's (or SUV's) trim is in place properly.

Door Sill Rail Clip
Part #: 955-559-547-00-M58

$3.75 and my driver's sill is ship shape.

Not intuitive as to how it does it's job, but there's a youtube on the install process, works like a charm (that you smack with a mallet).

Thanks Pelican!

Thanks Luccia,

If I had thought ahead, I would have... maybe next time!
