I am an owner of a 2018 Nissan Versa, 50k miles. Since last September (roughly a year) the passenger side of the car has flooded twice - there is a serious design flaw where the inner drainage system is easily blocked by leaves/environmental debris which results in an overflow of water behind the dashboard area. Rain water floods the entire side of the passenger area which, after reading other forums of owners with the same problem, sometimes impacts the cars electronic system which destroys the car. I am here to seek advice as to what to do with my car. How easily do cars rust and grow mold? I an extremely thorough with my cleaning and am able to effectively rid the car of any odors or water, but of course I can’t control what happens to the inner body. Is the car worth “keeping on top of”, or should I sell now before significant problems occur?
