Smart glass...dumb engineering.

BMW uses that feature on the 1 and 3 series cars. I've owned both. The 1 series is fine so far. But the 3 series was a pain. The switch is mounted in the door jamb on the striker assembly. The striker has a plastic coating and the switch is plastic. So over time the plastic wears down from opening and closing the door. A small thing like turning the air on high would put enough cabin pressure to trip the switch and the window would "flutter" up and down. Speed bumps, potholes, steep driveway angles, etc would twist the chassis just enough to mess with it.

You also had to remove the rear seat, door panel, access panel, etc to remove the striker for replacement since it didn't have a simple captured nut on the back. Stupid German engineering.

Unfortunately the chargers and challengers have some of that GREAT German engineering.
