Dear NHTSA, My 2016 Hyundai Santa Fe Sport (VIN: [XXX] , 2.0L Theta II, 64,000 miles) suffered engine failure with knocking and power loss, matching NHTSA Recall #20V-746 (Hyundai #198). This defect risks stalling or fire, threatening my safety and others’. Hyundai Motor America and Hyundai of Tacoma (Tacoma, WA) refused repair, citing the rebuilt title, despite the factory defect. Recall #20V-746 addresses Theta II bearing wear. My vehicle’s symptoms align, yet the dealer denied service, claiming the title voids eligibility. Hyundai’s April 2025 email noted three unrelated recalls (turbo oil pipe, ECM update, hood latch) were completed but ignored #20V-746, redirecting me to the dealer without addressing the engine or title issue. I’ve called Hyundai (1-800-633-5151) and emailed multiple times since March 2025, receiving only generic responses. The dealer’s refusal and Hyundai’s inaction leave the vehicle inoperable, posing a ongoing safety hazard on the road. The rebuilt title should not exempt a factory defect tied to a safety recall. The low mileage (64,000) supports my claim. I haven’t obtained a diagnostic report but am willing to pay for one (~$100–$200) if required. Hyundai’s refusal to honor #20V-746 violates safety obligations. Please investigate Hyundai’s denial, confirm if the Knock Sensor Detection System was installed, and clarify if a rebuilt title excludes eligibility. I seek engine replacement per the recall or a clear explanation. This issue has caused significant financial and safety concerns, and I urge swift action. Contact me at [XXX]or [XXX] Sincerely, [XXX] [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine caught fire while driving. Vehicle is a total loss as fire department did not arrive for 20 min. Currently at a Copart yard in Gainesville, ga. Lucky I was on a rural road and my dog and I were able to get out of car. Only injury is cough that has not gone away after 4 weeks. No warning lights, but did smell what seemed like burning brake fluid prior to fire. Both Hyundai and Farmers insurance have inspected the car. Of note is that Hyundai replaced the engine at around 60k miles due to engine oiling issues.

This Hyundai had the motor replaced with a Hyundai recall... they did not replace the one-time use fuel line that HAS to be replaced when removed. Started leaking fuel out of that line. while I was driving the fuel from the line caught the exhaust on fire and within seconds had flames engulf the car.

DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
