2019 Kia Sorento

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.

Gasoline smell is coming with the left side of vehicle. Gasoline is leaking from the fuel pump causing the gas to puddle creating the gasoline smell.

I am filing this complaint regarding my 2019 Kia Sorento and an engine failure related to Kia’s Product Improvement Campaign/KSDS (Knock Sensor Detection System) campaign. I purchased this vehicle used in 2022. Prior to the engine failure, I was never notified of any Product Improvement Campaign affecting my vehicle. Had I been notified, I would have immediately taken the vehicle to an authorized Kia dealership to have the campaign completed. My engine subsequently failed, and Kia denied coverage, stating that the Product Improvement Campaign was not completed before the engine failure occurred. Kia stated that notices were mailed to affected owners, but they have not provided me with documentation showing when my specific notice(s) were mailed, what address they were sent to, or proof that I was properly notified. I am concerned that affected owners may not be receiving adequate notification of this engine-related issue before a failure occurs. An engine failure can create a serious safety concern, especially if it occurs while driving, and owners may unknowingly continue operating vehicles affected by this condition without having the opportunity to complete the required update. I am requesting that NHTSA review this matter to determine whether Kia’s notification process for this campaign was effective and whether additional investigation is needed regarding engine failures associated with this issue. Vehicle Information: Year: 2019 Make: Kia Model: Sorento Date of engine failure: June 2026 I have documentation from Kia Customer Care regarding their denial of coverage and their statement that the campaign was not completed prior to engine failure.

The vehicle was slowly driven to the residence and stalled in the driveway. After restarting the vehicle, the engine immediately shut off. There were no warning lights illuminated. The vehicle was later towed to the local mechanic, who confirmed that the engine had failed. The vehicle was later towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. The cause of the engine failure was unknown. The vehicle was not yet repaired. While purchasing the vehicle, the contact was advised to constantly monitor the engine oil due to a known oil consumption issue. The manufacturer was notified of the failure and informed the contact that the vehicle was included in the extended warranty program. The failure mileage was 125,202.

Engine, a Lambda 3.3 v6 started knocking periodically and consuming oil at about a half a quart a week. It is a know problem with this motor and well documented in its existence in all Hyundai and Kia vehicles using this engine. We now have been told that the head bolts are partially stripped. Another known problem and we are consuming coolant. This can is not trustworthy and could fail at any time. We are still paying off the loan if it matters.

The paint is peeling in sheets, especially above the windshield, leaving the vehicle unprotected and vulnerable to rust. There were no chips or damage in this area prior to the paint beginning to peel away and once it started it's been progressing very quickly. Other owners have reported similar issues with this paint color (I believe it's pearl white) in Kia other forums online
