I have been chronically ill since I purchased my Nissan Versa Note 2 months ago due to a recurring mold problem. The seats, under the seats and the carpets have mold that keeps coming back regardless of cleaning or constant treatment of the mold. When I first saw the vehicle, there was a clump of mold on the floor. I thought that it was possibly from some moisture that had collected from a window being left down. The dealer cleaned the mold and I treated it, yet the mold keeps growing on the seats, under the seats and on the carpets. I feel that all seats may need to be replaced. Any help or comments are welcome. Thank you.

Did you buy used? If so, I bet your car was a salvage from flood damage or something. That's the only thing I can think of that would cause mold to grow.
