The vehicle suffered a sudden, catastrophic mechanical engine failure while driving. The vehicle completely lost acceleration, entered a low-pitched humming 'limp-home mode,' and the dashboard red oil pressure warning light illuminated solidly.The vehicle had previously received the mandatory corporate KSDS software update. A diagnostic check by an authorized Kia dealership officially documented the physical evidence of 'metal debris in the engine oil,' which is the unarguable signature of the defect described in NHTSA Recall campaigns for the Theta II engine block.Despite the physical evidence of connecting rod bearing failure and the active KSDS update, Kia Corporate and the local dealership have issued a flat denial of the Lifetime Warranty engine replacement mandate. This constitutes a direct violation of the safety recall settlement framework."

2 problems occurred within 1 month from each other: - Kia Sportage engine started to randomly stall. I needed to do a full stop in the middle of the road and restart the car to continue driving. I had 3 stalls happen within 2 weeks before I had time to take it to the dealer. The Kia Dealer held it for over a week and drove it but could not find any issues. They mentioned low oil, which was strange considering I recently replaced it. I also forced the dealer to do ignition tuning which seemed to have resolved the issue. - In a month after the first problem with stalling I experienced issues with the engine of unknown origin (so far). This happened this week. While going downhill cruise control shut off. After that the engine started to decelerate and the amber blinking engine light came off. Transmission started to be jerky. Dropped it off at the dealer again. I was very luck to not get into any major car accidents so far, but I was very close! Smells, sounds, and looks like a potential recall that Kia does not want to recognize.

On Sunday, June 1, 2025, I was leaving work and was exiting I97 to enter on 695 and and I accelerated to proceed on 695 and my vehicle lost power, the engine light along with the oil indictor came on, and making a loud knocking sound. The vehicle was towed and taken to the mechanic and the code read, "Knock sensor." The knock sensor was replaced at $301.85. I was able to drive the vehicle without any problems until Wednesday, June 3, 2025, when going to a doctor's appointment the vehicle's engine came on along with the oil indicator and the power was reduced and I had to pull over again with the same experience. The vehicle was again tested for codes and it then read Camshaft Sensor. This vehicle did not have any ill-performance, bells, dings, whistles or indicator lights until it was actually happening. According to the certified mechanic, this is a defect in the vehicle and although the part may be warranted, it will happen again and buyers will still have to pay for the part and labor, again, to have it fixed. I do not have my invoice on hand, however, I can get another copy.

Was able to get it to an autoshop (O'Reilly's) diagnosis shows knock sensor failure and they told me it has to do with the safety recall, didn't even know the car had a recall on it.

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651.

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.
