Both my wife's 2020 Model Y and my 2021 Model Y have the same issue, almost immediately after delivery. I have scheduled a service with Tesla, and they want me to approve at $125 repair cost per car. Something tells me that this is a design/build issue. I live in Colorado, where the air is dry, and mold/bacteria simply does not grow. I've never had this issue in any of my previous cars. Does anybody have any insight into this?
