Is it a common problem with Toyota cars to have problems with water leaking in.

Could be a issue with tree leaves and debri working its way into the A/C drain and stopping it up. This can happen with any brand of car....has more to do with where the car is parked. Folks that have lots of trees and debri in area where car is stored has been a problem for as long as I can remember.

Oh. i have already been here no comment!!!.
