Hi All - I bought a CPO 718 S in January and have had a few issues with the car. One is the passenger window rolls up that final quarter inch about 30 seconds after the drivers door is closed. It closes completely when the passenger door is closed, then rolls up again after the drivers door closes. I have taken this to my local dealer twice and they say it's normal but I just dont find that believable. Do any of you also experience a delayed window closure? Normal?
