NHTSA Complaint #11693194 — 2025 LEXUS NX

I purchased a brand-new 2025 Lexus NX 350 from Lexus of Smithtown, NY less than two months ago. At around 1,300 miles, I discovered a large amount of water pooled on the front passenger floor and could hear water sloshing inside the vehicle while driving. I immediately brought it to the dealership for inspection. According to the dealer’s service report dated October 13, 2025, technicians found the A/C drain clogged, removed the carpet from the front passenger area, and confirmed the padding was soaked with water. They recommended replacing the carpet, padding, and performing an A/C refresh service, estimating about $7,000. The dealership stated the issue was caused by “outside influence” and referred me to file an insurance claim rather than covering it under the new-vehicle warranty. The vehicle has never been exposed to flooding, road debris, or unusual environmental conditions. It is kept in a clean residential garage and driven under normal use. Given the extremely low mileage and short ownership period, this appears to be a manufacturing or design defect in the HVAC condensate drain system rather than external damage. Water intrusion inside the cabin poses potential safety and health risks, including mold growth, corrosion of electrical components, and possible impact on airbag or electronic systems. Similar A/C drain and water-leak problems have been reported by other Lexus NX owners in prior model years, suggesting a recurring design weakness that may also affect the 2025 model. Lexus should investigate whether the A/C drain design or installation allows premature blockage and issue a Technical Service Bulletin (TSB) or recall if appropriate.
