NHTSA Complaint #11716493 — 2017 HYUNDAI SANTA FE

Current Mileage: ~94,000 miles Ownership: Second owner (purchased less than one year old at 17,035 miles) I purchased this vehicle in December 2018 when it had approximately 17,035 miles. Since purchase, the vehicle has been consistently and properly maintained, primarily at authorized Hyundai dealerships, with documented oil and filter changes throughout my ownership. All required Hyundai recalls and updates have been completed. As confirmed by Hyundai service records, my vehicle is eligible for extended warranty protections under the Theta II Engine Settlement, which explicitly applies to subsequent owners and is not limited to the original purchaser. Engine Failure & Repair History Beginning in mid-2025, my vehicle began to exhibit progressive and excessive oil consumption, despite regular maintenance. Hyundai dealerships performed multiple Hyundai-directed corrective actions, including: PCV valve replacement Multiple oil consumption tests Combustion chamber cleaning (paid out of pocket after Hyundai Motors denied goodwill) These measures failed to resolve the issue. Hyundai’s own oil consumption testing confirmed: 1.2 quarts consumed, followed by 1.4 quarts consumed, indicating worsening internal engine failure West Houston Hyundai has subsequently advised that engine replacement is required, yet Hyundai Motor America has refused coverage, and I was quoted $5,872 for engine replacement and labor at my expense. Engine failure requiring replacement at 94,000 miles is not normal wear and tear and is inconsistent with reasonable consumer expectations or Hyundai’s powertrain representations. Importantly: The vehicle has never been cited for neglect, sludge, or improper maintenance,Oil consumption worsened after Hyundai-directed repairs Hyundai has not identified any misuse or disqualifying condition The failure pattern is consistent with known Theta II piston/ring defects
