NHTSA Complaint #11675285 — 2021 LEXUS RX

My 2021 Lexus RX 350 (mileage approx. [19,000], has developed a severe mold contamination issue caused by HVAC condensate drain failure. This issue is a known design defect covered by Lexus Technical Service Bulletin L-SB-0020-21, which identifies blockage or poor drainage in the HVAC system that allows water to enter the cabin. As a result, water intrusion under the carpet has led to mold growth, making the vehicle uninhabitable and unsafe to drive. The cabin now contains visible mold and musty odor, raising serious health and air quality concerns. I brought the vehicle to Lexus of Route 10 (Whippqny, NJ), who acknowledged the water intrusion but have refused to repair it under warranty or goodwill. Instead, they are pressuring me to file a personal insurance claim, even though the issue stems from a known factory defect. The vehicle has now been out of service for weeks, and I am driving a loaner vehicle while mold continues to worsen in mine. Lexus Corporate stated that they "no longer goodwill" these repairs, despite the ongoing safety and hygiene risks. There has been no recall or warranty extension, and I believe other owners may be similarly affected by this unresolved defect. This is a serious safety issue due to the potential for mold-related health problems, interior air contamination, and possible electrical damage from long-term moisture. I urge NHTSA to investigate whether this HVAC defect poses a broader consumer risk, and whether Lexus is avoiding its responsibilities to repair or disclose this issue to other drivers.
