Driving under normal conditions April 20,2026, on the way to school. Got off the freeway and the vehicle immediately shut-off and the check engine light came on. Vehicle was stuck partially in the roadway and would not move. Vehicle was towed to Kia dealership and they found that there was no oil in the engine and that the oil drain plug was completely missing. This problem caused catastrophic engine failure resulting in the need for a full engine replacement. A routine oil change had been conducted approx. 2,000 miles prior to this on January 12, 2026. The vehicle had been driven daily since that oil change with no noticeable oil leak or problems preceding this event. Had this event occurred at freeway speeds, it could have caused serious injury to the driver and other motorists on the roadway at that time. It appears that the drain plug fell out since there was no other additional or noticeable damage to the oil pan or surrounding the drain plug itself. This information was confirmed by a photograph taken by the dealership conducting the repairs.

To Whom It May Concern, I am submitting a formal complaint regarding a serious safety issue involving my 2021 Kia Forte. Approximately one year ago, I purchased this vehicle used with approximately 56,000 miles. I have owned the vehicle for nearly a year without prior incident until a recent and significant failure occurred. While driving on a highway after work, the vehicle suddenly lost engine power. The RPMs dropped abruptly, and the vehicle began decelerating rapidly before completely shutting off. This occurred without any prior warning indicators, such as dashboard warning lights or messages. I attempted to restart the engine three times before it successfully turned over. Upon restarting, the engine produced a loud knocking noise that had not been present before. Since this incident, the vehicle has been unable to operate reliably. It will start and run briefly but stalls again after a short distance. The knocking noise persists, suggesting a serious internal engine issue. The vehicle remains in my possession and is available for inspection. Component/System Involved: The failure appears to involve the engine and/or internal engine components. The exact cause has not yet been diagnosed by a professional. Safety Risk: This failure posed a significant safety hazard, as the sudden loss of power occurred while traveling on a highway. This could have resulted in a serious accident, particularly if surrounding traffic had been heavier or less responsive. Inspection and Diagnosis: The issue has not yet been formally diagnosed or confirmed by a dealership or independent repair facility. Additionally, the vehicle has not been inspected by the manufacturer, law enforcement, insurance representatives, or other entities. Warning Indicators: There were no warning lights, messages, or other indicators prior to or during the initial failure. The only symptom Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Kia Forte. While driving at various speeds, the check engine warning illuminated. The vehicle would start to vibrate. The vibration was more evident while slowing down or stopping at traffic lights. The vibration and the warning light had become a recurring failure. After turning off and restarting the vehicle, the check engine warning light was cleared. However, lately, turning on and restarting the vehicle failed to clear the warning light. Additionally, the vehicle lost motive power and stalled several times. While the vehicle was stopped and idling, the RPM was fluctuating as if the accelerator pedal was depressed. The vehicle was taken to the same dealer several times; however, the dealer was unable to duplicate the failure. The contact was advised that the vehicle was in good working order. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

On May 13, 2023, I was involved in a severe frontal collision on the passenger side while driving my 2021 Kia Forte. The impact caused significant damage, and my insurance company declared the vehicle a total loss. Despite the severity of the crash, none of the airbags deployed. I experienced body pain for several days following the accident. Given the nature of the collision and the damage sustained, the airbags should have deployed to protect the occupants. This raises serious concerns about the reliability of the Supplemental Restraint System (SRS).

I am writing to report a serious safety concern involving my Kia vehicle. Shortly after getting an oil change, my car began making unusual noises and then suddenly stopped working in the middle of a busy intersection. This unexpected stall created a dangerous situation for both myself and other drivers. After having it towed to the dealership, it comes down to an engine malfunction which was not covered by my warranty since it just hit 70,000 miles. I have since learned that other Kia owners have experienced similar issues, and I am concerned this may be related to a larger defect or recall issue. I wanted to report this incident to ensure it is properly documented and investigated.

CUSTOMER SATISFACTION CAMPAIGN: OWNER NOTIFICATION (CS2312) - This document is the owner notification advising that Kia is conducting Customer Satisfaction Campaign. A software upgrade that addresses the social media theft method has been made available to owners of eligible Kia model vehicles free of charge at authorized Kia dealers since 2023. In addition to the anti-theft software, a new zinc-reinforced ignition cylinder protector hardware upgrade has been developed and can be installed at the ignition cylinder location to provide additional protection against the social media theft method.

(Mailing of these notifications to vehicle owners will be completed from December 17, 2025 through February 27, 2026)

PITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a “Warning Lamp’ to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)
