My son's trunk gutter drains got clogged again -- he parks under an evil tree at school. He tried to clean them, but only succeeded in ramming the plant matter into one of the crroks in the pipe. We had to remove the trunk side interior pieces and detach the hoses to get the clogs out. A real pain.

My advice is to check the drains periodically, and, if they seem slow, flush them with a hose before they get really clogged. Sometime in the fall and after the leaves have fallen would probably be the best times.

Check Sunroof drains

Check Air Conditioning water drip hose (On other makes of cars, I have had my interior carpeting soaked with water)
