NHTSA Complaint #11682430 — 2023 HYUNDAI SANTA FE

AC evaporator drain design problem June, 2024 approx. 3500 miles under warranty, AC evaporator drain line backed up into the passenger front right. Brought it to service - they unclogged and drained the line at no charge. June 2025 approx. 12,K miles under warranty, AC drain backed up again. The excess water drained onto my feet as a passenger and collected under the front seat, saturating the rug area, potentially causing additional mildew and respiratory causing irritation. Service required an appointment. drained it charged $88. Filed a complaint incl Hyundai Motors ; was told the $88 charge was irreversible - cause was weather. The CAR HEALTH HAZARD seems to stem from a major design flaw The air intake is in the windshield wiper cowl resulting in wet tree and leaf debris , bird droppings, etc collect even when the car is not in use. Thus, when heat or air conditioning is activated, air comes in through the air intake and then through the difficult to acces filter recessed behind the glove box , then into the passenger area When the AC drain hose is plugged, it backs up through the dirty filter and then out, to accumulate under the passenger seat allowing more mildew. Re:My 2024 mile blockage, the water was drained, but the filter was not mentioned. In 2025 with the $88 bill, the water was drained no mention the filter. Draining the water does not correct the problem. It should be required at every service the l drain hose is checked, water drained. and filter changed at no charge until a design correction to cover the cowling or an interim solution is installed We lnotice that we have sporadic respiratory problems in the first of miles of riding in all the car From Hyundai Motor America - We expect reimbursement for the $88 service charge. Warranty draining the water and new filter annually. and an NHTSB approved fix of the problem and an NHTSB approved redesign of future models
