I have this problem and can recreate it consistently. It happens when I go over a bump while the window is in upward motion. For example, it just so happens that there’s a natural “speed bump” across the end of my driveway. When approaching home, I’ll stop and get the mail from my roadside mailbox. As I pull away from the mailbox and start turning into the driveway, the window is on the way up. As soon as I hit the bump, the window retreats. Every single time. Now that I know what to look for I can recreate it on many other bumps. Perhaps it’s an obstruction-sensor calibration issue. Window recalibration procedure has no effect on symptoms.
