My wife was driving home. She had taken the highway home when she had suddenly lost power with no warning or indication from the cars dashboard there was no warning lamps or messages explaining why the car lost power and that the car would not turn back on. The vehicle was towed to an independent mechanic where it was determined that the engine was seized up and that the motor needed to be replaced and that the car had no oil in the engine. Which is not possible since the cars Maintenace intervals were maintained. It was also later determined that the oil pan bolt was under tighten due to bad threading on the oil pan and bad oil pan seals. The car will be towed to a dealership for further inspection. This issue presents a possible fire hazard or risk of accident while at high speeds. My wife did suffer a small injury to her forehead after rapid loss of speed from the steering wheel.

The oil plug fell out of my Tuscon while I driving on the highway and it burned out my entire engine on January 2, 2023, at approximately 5:40 pm EST. The tech at the dealership found the plug in the tray under the spot where the plug goes. It was inspected by a technician at a Hyundai dealership. The car is a 2018 Tuscon--had less than 55,000 miles on it and is now basically worthless and undrivable, quoted $13,000 to fix it. My entire engine now needs to be replaced. I was within the lifespan of my last oil change when the plug fell out. A red oil light flickered on and then a battery subsequently came on. Within approximately three minutes of the light first flickering on, the car was dead on the side of the highway. The car would not turn over once it was stopped on the side of the highway. The car is still at the dealership and available for inspection as of today, but I am not sure how long it will be there because I am not sure what is the best path forward in terms of repair because of the financial cost. I'm lucky that I was able to navigate my car onto the shoulder of the highway and secure a tow without injury. It was a very foggy day and it was already dark when this occurred and I was afraid I would be struck if I exited my car. My car drifted to a stop at the start of an exit ramp with a highway barrier that prevented me from going farther right onto the shoulder.

Engine (1.6-liter turbocharged direct-injection four-cylinder) had a catastrophic failure driving along highway. Engine instantly lost power and stalled. No indicators on instrument cluster prior to engine stall, temperature gauge for coolant indicating nominal conditions. Upon pulling over to the side of the road, check engine & batter indicator lights shown on the instrument cluster. Hyundai's roadside assistance system, Bluelink, did not activate with the engine's stall. It was observed that a mix of antifreeze and oils were dripping behind the engine onto the ground. Dealer later discovered that a piston connection rod had punched through the wall of the engine block. Dealer has submitted issue to Hyundai Corporate. Vehicle is aggressively service with manufacture dealerships according to recommended service intervals with synthetic fluids.

Vehicle stalls when accelerating at low speeds. It appears to be a delay when the car transitions from 1st to 2nd gear. This creates a safety concern, especially when taking turns into traffic due to delays/stalls when turning.

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.
