Yes, this had to be some kind of a 1 car malfunction. Ours do not do that, and neither did the wipers on my '07 rental, and as said, there is no Rainsense feature on this car...just a salesperson who needs to learn the product.

I always found oddness with having both the click up for speed and the rotation to then modify speed on top of that (someone should know what I mean here?), but got used them after a few days. This is how most are now, though. Mom hasn't said a thing about her '08, and all is fine and dandy.

Just throwing this out there...but after about a year, the wipers on our '04 Suburban started doing funny things like that, intermittently, and they traced it back to a bad wiper control module (basically, wiper "brains"). That kind of thing could be the issue here.
