It happens very often to me.
When i turn off the car and I do the one-touch closing of the windows, they arrive at the top and than go back down as they found an obstacle.
It also often happens when I close the windows using the long touch on the key, and that's more annoying since I've to get back into the car to close them.
Does it happens only to me?
I've tried to set up again full open and full closed position, but the problem (if we can call it a problem) always come back.
