2018 had that available (all 4 auto up/down). My 2017 rear passenger would roll back down a little bit if you didn’t watch it... it was not auto up/down... even holding the switch and rolling one up this can happen.This is so crucial and I've seen/heard (locally even) many reports about this problem. Thanks for sharing and welcome!
Interesting that this "spot" is getting more runoff. I installed the window shades and wonder if this will minimize the problem. Guess I should clean the gasket anyhow. Always best to deal with critical spots before they become a problem.
Were there not other spots, rear pass, that were also having an issue? Seems I saw/read about Tourings that had the auto feature for the rears windows doing this? 19's or 20's?
