Loss of Motive Power
the federal safety agency 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 under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitionersâ 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. ODIâs evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to the federal safety agency 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. Â 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 the federal safety agency's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, the federal safety agency does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing the federal safety agencyâs reasons for denial of the petition will be published. The reference numbers for the complaints to the federal safety agency 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

What 2021 Kia Sorento owners say
Most recent owner complaints, unedited.
This is my third report regarding a dangerous loss of drive power on my vehicle, which completely matches the federal safety agency Recall 22V760000. Kia of Rainbow City in Alabama diagnosed the failing transmission oil pump in March 2026 but refused to honor the recall because a software patch was previously marked 'complete.' The dealership has since deactivated my digital access to the inspection report. The manufacturer is actively leaving a verified, life-threatening safety defect on the road.
While driving my 2021 Kia Sorento, the electronic power steering suddenly failed/intermittently cut out while the vehicle was in motion. The steering wheel became extremely stiff and difficult to turn, making the vehicle very hard to control and creating a serious risk of a crash. I had to muscle the wheel to get out of traffic turn the vehicle off and on several times before steering worked again. Because the steering failure occurred while driving THREE TIMES in the last two weeks and could recur without warning, I considered the vehicle unsafe to continue operating and had it taken to a Kia dealership for inspection. The vehicle has also experienced repeated electrical/electronic issues, including difficulty starting and recognizing both key fobs. Every time now, the engine requires approximately 3–4 attempts to start. There have also been problems with the climate-control system and other electrical components. I am concerned these issues may be related to a broader electrical, voltage, control-module, or electronic power-steering problem. The vehicle is currently available for inspection by the dealer/manufacturer upon request. The exact cause of the steering failure has not yet been confirmed. I have requested that the dealer inspect the electronic power steering system, retrieve any stored or historical EPS/IBU fault codes, and evaluate the vehicle’s battery, charging system, grounds, wiring, and related electronic control modules. The steering failure created an immediate safety hazard because normal steering assistance was lost while the vehicle was moving. There was little or no meaningful warning before the steering became extremely difficult to operate. I am reporting this because I am concerned the condition could recur and result in loss of vehicle control. I have two small children and this is my only means of transportation.
Kia completed Recall SC250 via a software update only. The physical hardware has now failed (Code P193B). Kia Corporate and the local dealership are refusing to honor the safety recall remedy because the software update marked the recall 'complete,' leaving a failed, dangerous transmission unaddressed.
I own a 2021 Kia Sorento 2.5L Turbo AWD with approximately 150,000 miles. In the evening, while driving home after dinner with my daughter in the vehicle, I was traveling in the area of [XXX] and [XXX] when the vehicle displayed a “STOP SAFELY IMMEDIATELY” warning. The vehicle unexpectedly slowed down/appeared to brake on its own while I was driving. There was no check-engine light at that time and the warning did not remain on, so I did not initially know what caused the incident. Approximately two weeks later, the vehicle developed delayed shifting from 1st to 2nd gear. RPM increased from about 2,000 to 3,000 before the next gear engaged. Switching from ECO to Comfort mode initially seemed to help, but later that day the problem worsened even in Comfort mode and also began occurring from 2nd to 3rd gear. The check-engine light then came on. O'Reilly Auto Parts scanned the vehicle and reported codes P0868/P086800 (Transmission Fluid Pressure Low) and P193B79 (High Pressure Electric Oil Pump Performance). Kia has not yet diagnosed the current problem, and the vehicle is available for inspection. Kia checked my VIN for recalls sometime in 2025 and advised there was no open recall. I am aware of Kia Safety Recall SC250/the federal safety agency Recall 22V‑760 involving the 8-speed DCT electric oil pump on certain 2021-2022 Sorento vehicles. I am concerned because my vehicle experienced the “STOP SAFELY IMMEDIATELY” warning and unexpected slowing and now has worsening transmission symptoms and related diagnostic codes. I am concerned the vehicle could unexpectedly lose drive power while being driven. I request the federal safety agency review whether my vehicle's condition may be related to the existing safety defect and whether additional vehicles should be investigated.

Car stalled July 14th car has been at Kia of Bowie and they are stalling g me and dont want to do the sarter recal and are asking me for $550 for a diagnostic that I should not pay for do to this safety recall ive been telling them from the start that there was a very strong gas smell coming from theoil dipstick and they have been avoiding it till yesterday now the gas has evaperated and they are asking g me to pay $550 for the leak down test.
On XXX im driving my 2021 Kia Sorento sx it stalled while driving in the mist of traffic engine light comes on and I had my car towed contacted Kia of Bowie they are giving me a hassle contacted them because this is a safety issue from the beginning I have mentioned gas smell coming from the oil dipstick now the car has say and the gas has evaperated and they are saying no gas smell contacted corporate and Istill have no results. This is a serious issue and I am being mishandled and treated as if this is not a severe safety hazard and needs to be addressed by Kia I am asking for assistance PLEASE IN SERIOUS SAFETY MATTER.
"The vehicle has twice suffered a sudden, catastrophic loss of motive power at highway speeds (approx. 70 MPH) on the interstate, forcing the driver to coast across active traffic to the shoulder without engine pull. The engine revs freely in 'Drive' but the transmission fails to engage any gears. No dashboard warning lights, check engine lights, or diagnostic trouble codes are triggered during or after the failure. The failure resets temporarily only after cycling the ignition key off and on.The vehicle previously had Safety Recall SC250 (8-speed Electric Oil Pump) performed by an authorized dealer, but the software flash completely failed to prevent this catastrophic hydraulic/electronic failure mode or provide the federally mandated dashboard warning countdown. The vehicle is entirely unsafe to drive,
previous warranty repair for a failed fuel injector (RO #1103175) resulted in severe gasoline dilution of the engine oil. the vehicle now vents raw fuel vapors into the cabin (Fire Hazard) and hesitates/jerks when braking at stoplights (Stall/Crash Hazard). Kia Corporate has refused to communicate for over two weeks while the dealer holds the car.
I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a transmission failure. The transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. This defect has put my safety and the safety of others at risk. On several occasions the vehicle failed to respond properly when accelerating, including while entering highways and driving in traffic. The hesitation and sudden loss of power created fear and anxiety because I could not trust the vehicle to operate as expected. The problem has been reproduced and confirmed by a repair facility, and the symptoms are consistent with a transmission torque converter clutch failure. I also contacted Kia and provided the vehicle information. Kia informed me that they would not repair the vehicle because it has exceeded 100,000 miles and that the recall or warranty extension had expired. However, my vehicle is experiencing the same transmission-related symptoms reported by many other Kia owners.I never received any recall notification because I purchased the vehicle from a dealership as the second owner. Had I been properly notified, I would have taken the vehicle in for inspection much earlier or would never have purchased the dangerous vehicle in the first place. It is extremely frustrating and costly to be denied assistance solely because of mileage when the failure appears to be related to a known transmission defect.Before the failure, the check engine light illuminated and then went away even though the issue did not. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse. I reported this to Kia on a previous service visit to Romeo Kia in Lake Katrine, NY and was told they did not find anything wrong. This situation has caused significant emotional stress and anxiety. I am requesting a full review and a fair resolution from kia. Thank
