NHTSA Complaint #11690735 — 2018 TESLA MODEL 3

Mold, mildew and smelly odors are coming through the on-cabin ventilation system. This is the 3rd time since 2020, I had to purchase & replace the two air filters and spray the poorly designed duct & condensation accumulation. I inspected the self-installed air filters and there were no signs of moisture, mildew, mold or stains on the filters, which makes me think the problem was /is from the HVAC condenser or coil area. Tesla had issued a 2019 software update to “run” the ventilation system longer after the vehicle was in “Park” but the software update has NOT solved the mildew and bacteria odors that are vented into the cabin, and subsequently changed the HVAC design in post 2021Tesla models that corrected this problem with many pre-2021 Model 3s. Tesla Service Centers are still charging for the coil spray cleaning and not covering this mold & bacteria-creating HVAC design problem of their earlier year vehicles ca as I had to pay Tesla for a pair of air filters change and now they want me to pay for a separate fee for spraying the condenser coils.
