Is the rear windows not going up properly over time a known issue with A3's?

my car is 2006 only had it for 2 months now and the Rear Passenger Side window has issues going up if its put down. seems to come off track some how goes down when the window is raised up halfway while trying to fully close it. its slow going either way, so not sure if its the track or maybe both whole assembly motor and track that is the issue as I really dont want to bother with it since its cold out tho will be taking door apart in spring probably to give it a look at.
