Severe structural manufacturing defect in my 2021 Kia Sportage. A physical hole has formed in the floorboard on the driver side directly next to the pedals, creating an immediate risk of a catastrophic accident. The vehicle also has chronic failure of the air conditioning system, documented by Sunset Kia of Sarasota as a leaking evaporator. This prevents the windshield from defrosting during heavy Florida rains, severely impairing visibility. Dealer confirmed these hazards under a signed repair order on June 3 2026, but Kia Corporate closed case 25175676 without any physical technical inspection, leaving an unsafe vehicle on the road.

On June 14, 2026, the driver experienced sudden rough engine running followed immediately by a flashing check engine light. The vehicle was towed to the selling dealer, which has performed all prior maintenance. The vehicle is currently at the dealership and available for inspection. Technician notes show DTC P1326 was stored — the Knock Sensor Detection System code associated with connecting rod bearing wear on Kia's Theta II engine family. The technician performed an audible knock check only (none heard) and cleared the code. The vehicle was found approximately 2.5 quarts low on oil due to an internal turbo oil leak. The dealer's notes state the code "may be related" to low oil — hedged language, not confirmed causation. The dealer confirmed the turbo failure but has not performed a bearing clearance test to confirm or rule out bearing damage from the low oil condition. The dealer performed a turbocharger replacement. Despite a verbal commitment from the service manager that a bearing clearance test would follow, no such test was performed 40 days later. When the vehicle was declared ready, the service manager did not recall the commitment and suggested driving 40-50 miles as an alternative. Kia America opened a formal case last month and authorized a partial goodwill adjustment but no one has addressed the safety concern of the unperformed engine test indicated by the thrown code. Driving a vehicle with potential connecting rod bearing wear risks catastrophic engine failure, creating a serious safety hazard. This vehicle has a documented history of oil consumption prior to this incident. The engine has not been cleared for bearing damage following a significant low oil event and a stored P1326 code.

While driving southbound on Route 93 on 6/11/2026 during the morning commute, my 2021 Kia Sportage suddenly sputtered and lost the ability to accelerate. I was traveling about 65 mph in heavy traffic when the vehicle abruptly lost power without any warning lights or prior symptoms. As my speed dropped, I had to cross multiple lanes to reach the breakdown lane, creating a dangerous situation for me and surrounding drivers. The vehicle had to be towed to a repair shop, where I was informed that the high‑pressure fuel pump had failed and needed to be replaced. The car has only 22,000 miles on it and is just one month out of warranty. This sudden loss of drive power at highway speed poses a significant safety risk.

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.
