Components: ENGINE
Subject: 3.3L Engine Loss of Motive Power (LOMP)
Opened From: 2024-02-08 - 2024-05-16
Summary
The Office of Defects Investigation (ODI) received a petition on February 2, 2024, requesting a defect investigation into an alleged defect of the "engine" on the following vehicle model: 2017 Hyundai Santa Fe vehicles equipped with the 3.3L V-Shaped GDI Lambda-II engines. The petition cites allegations of a loss of motive power, often resulting in an engine seizure. The stall is preceded by a knocking sound, decreased performance and no warning lights. An analysis of the subject vehicle population was undertaken using complaints submitted to ODI along with manufacturer data.-? It was determined that the frequency of events is low for the subject population, while those that specifically report a loss of motive power event have a high mileage at the time of incident.-? The 2017 Santa Fe is equipped with a service interval reminder for the consumer that must be set by the consumer themselves or at a dealership.-? A Technical Service Bulletin (19-EM-002H) instructs the dealership to set the maintenance reminder at the completion of routine maintenance service or anytime a repair is performed that requires new engine oil.-? This maintenance reminder will help reinforce the need for proper oil maintenance intervals.-? Additionally, the Santa Fe vehicles with 3.3L V-shaped Lambda-II engines will be added to HyundaiG??s existing Technical Service Bulletin (23-EM-007H) related to combustion chamber cleaning.-? These actions will help limit negative consumer incidents related to loss of motive power.-? Lastly, Hyundai has extended the limited engine warranty for MY 2013-2019 Santa Fe vehicles equipped with 3.3L V-shaped Lambda-II engines included in the Petition.-? The updated coverage is 15 years, or 150,000 miles and details are contained in Technical Service Bulletin 24-EM-003H. In view of the service interval reminder, combustion chamber cleaning, and extended warranty actions being taken by Hyundai, ODI is denying this Defect Petition.-? The agency reserves the right to take additional action if warranted by future circumstances.-?
