NHTSA Complaint #11679355 — 2017 HYUNDAI SANTA FE

Subject: Urgent Safety & Warranty Concern – 2017 Hyundai Santa Fe Sport (TSB #21-01-002H) Dear Hyundai Customer Care and NHTSA, I am reporting a serious safety and warranty concern regarding my 2017 Hyundai Santa Fe Sport (VIN: [XXX] , mileage:97,320). The vehicle is exhibiting excessive oil consumption after an initial Consumption test burning 3quarts of oil in 725 miles as well as causing damage to the intake manifold requiring it to be repaired and is consistent with the connecting rod bearing defect covered under Hyundai TSB #21-01-002H. This TSB extends engine coverage to 10 years/120,000 miles for precisely this issue. Despite this, my authorized dealer, Premier Hyundai of Moreno Valley has refused to take immediate corrective action and is requiring me to drive an additional 1,000 miles before performing the repair — a delay that increases the risk of catastrophic engine failure and endangers vehicle occupants and other motorists. Key points: This is a documented defect with a known history of sudden engine failure. TSB coverage and my warranty should apply immediately, without dangerous delay. The dealership’s requirement to continue driving the vehicle is unreasonable and unsafe. I am requesting: Immediate authorization for the engine diagnostic and replacement under TSB #21-01-002H. Confirmation from Hyundai that I am not required to continue operating a defective engine to “prove” the defect. NHTSA to log this complaint as part of the ongoing safety concerns regarding Hyundai Theta II engines. Please respond within 5 business days with next steps. I am prepared to provide full maintenance history, documentation, and dealership correspondence. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
