NHTSA Complaint #11697649 — 2022 TESLA MODEL 3

Shortly after purchasing my 2022 Tesla Model 3 RWD in February 2025, I began noticing a persistent musty, mold-like odor coming from the HVAC vents whenever the air conditioning or defrost was on. The odor worsens when driving with the windows down. I reported this issue to Tesla multiple times between May and October 2025. Tesla replaced the cabin filters but refused to perform a full evaporator or HVAC disinfection, stating the odor was “normal.” Despite the filter changes, the smell always returns within a few weeks. Between these visits, I also tried to resolve the issue myself by replacing filters, using odor-eliminating products, and placing moisture absorbers inside the vehicle, but nothing has resolved the problem. This ongoing issue has led to repeated respiratory and eye irritation, including a documented pneumonia case in April 2025. The symptoms clearly worsen after time spent in the car. Tesla has not offered any permanent fix, warranty repair, or replacement. The problem appears to stem from mold or microbial buildup within the HVAC evaporator and duct system, which could affect air quality and occupant health. This raises safety concerns regarding possible HVAC design flaws or moisture retention issues that may affect other Tesla vehicles. The issue is ongoing as of November 2025 and has been reported to the Florida Department of Agriculture and Consumer Services (FDACS Case #2511-00831) for further review.
