My 2019 Hyundai Kona SE (2.0L Nu MPI/Atkinson engine) was previously subject to NHTSA Recall 21V301000 (Hyundai Recall 203) for defective piston oil rings that can chip and cause accelerated oil consumption, engine knocking, and stalling. That recall's remedy was performed under a prior owner in December 2021. In November 2025, a Hyundai dealership installed a Cylinder Noise Diagnostic System (CNDS) software update (Service Campaign 974) specifically meant to detect this defect's vibration signature before it causes engine damage. Approximately 7,000-8,000 miles and about nine months after that software update, the vehicle stalled unexpectedly while being driven on two separate occasions, with no check-engine light or other warning beforehand. A third stall left the vehicle unable to restart. It was towed to a service station, which found no engine oil and no external leak. A Hyundai dealership subsequently diagnosed cracked valves that allowed approximately 5 quarts of oil to burn through the engine, and determined the engine requires complete replacement. This is the same failure mode (oil consumption/engine damage leading to stalling) that the original recall and the 2025 software update were both meant to prevent, and the software gave no advance warning before the stalling occurred. The vehicle and dealership diagnosis are available for inspection upon request.

One day after I filled my gas tank, I noticed a strong gasoline smell outside the car. The next morning, I noticed a huge puddle on the pavement under the fuel tank.

One day after I filled my gas tank, I noticed a strong gasoline smell outside the car. The next morning, I noticed a huge puddle on the pavement under the fuel tank. At least a gallon of gasoline must have leaked out overnight while the car was parked. I also noticed that gasoline continued to drip down from the fuel tank to the ground. I then had the car towed to the mechanic and they discovered a crack in the mounting flange on the top of the plastic fuel pump. The car was not in a collision and there was no external force that could have caused the fuel pump to crack and leak.

Yesterday my car, Hyundai Kona 2019, stalled out for no reason while the vehicle was in motion. There were no warning signs on the panel. I change the oil regularly, but the car keeps burning oil very quickly before the next planned oil change, however, I never have any warning signs that my oil level is low. I could have gotten into an accident, and now I am afraid of driving because the car can stall at any moment, and cause an accident. The manufacturing company doesn't s solve this problem in a timely manner!

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
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.
