anyone else have this issue? When my door is opened and windows comes down slightly, sometimes goes all the way down when door is closed - hard to get back up. Sometimes works, sometimes doesn't. Had adjusted multiple times, but I think the motor is broken - of course warranty is now up and they want me to pay for. Dealer has just made adjustments, won't pay for motor replacement so far

 

The dealership is probably just doing a reset. Theres more to it than just a reset. If you search for window reset, you should find some details as to what really needs to be done (actually removing the motor and cleaning out the carbon build up).
Or they could just replace it. if your not inclined to do the reset yourself keep taking it back, eventually they will get tired of dealing with it and replace the motor.
Hope that helps
