general problems of the 2000 Subaru Outback

Passenger side sun roof drain plugs up. Backed up water drains into inside rear cargo area. My vehicle came equipped with the large all weather rubber mat in the cargo area. Since the area where the water pours out is near the right rear of the car the most of the water ends up on the carpet under the mat and it is not always noticeable. Spoke with contractor that comes in and takes care of water leak for dealer he said is the fix should take care of problem. Found it distracting while driving that water was pouring down inside of car, could see in rear view mirror. Once water drained out leak stopped, but water would build up again. Worry about possible damage to headliner and future body structural integrity due to water leaking into roof area.
