“Reason for Dispute & Desired Resolution: I am filing an executive escalation regarding a catastrophic engine failure on my 2020 Kia Soul, which is actively included in the Piston Oil Ring Safety Recall (Campaign SC209). The engine suffered a total structural failure where a rod broke and punctured a hole directly through the engine oil pan. The vehicle is completely undrivable and presents an environmental hazard due to active fluid leakage. Standard Kia Customer Care and Roadside Support lines have officially denied emergency towing assistance and rental car coverage, stating they cannot help. The closest authorized dealership, Kia of Columbia, has an appointment backlog delaying an official inspection until October 29th. I cannot afford the out-of-pocket costs for an hour-long flatbed tow from my home or weeks of upfront rental car fees. As a consumer, I am being penalized and left stranded by a severe manufacturing defect that Kia has legally acknowledged. I demand that Kia’s Executive Resolution Team immediately issue a direct digital dispatch code to authorize a free flatbed tow to the dealership, and establish a direct-billed loaner or rental vehicle (via…”
“The vehicle experienced complete and sudden engine failure while actively driving on a roadway. The engine began making loud, violent knocking noises, the check engine light illuminated, and the vehicle completely stopped and lost all motive power mid-drive. I believe this is directly caused by the defective piston oil rings covered under NHTSA Safety Recall Campaign 21V-259 (Kia Campaign SC209). The vehicle had only just begun exhibiting these severe symptoms on the exact day it stopped working. The loud engine knocking, immediate check engine light, and rapid internal oil loss all occurred rapidly within hours of each other on the same day, leading directly to the total mechanical failure and seizure. The engine component is currently intact and remains completely available for physical inspection upon request. The engine in my Kia Soul is the 2.0L Nu MPI. The vehicle was towed to an authorized Kia dealership service center. The dealership confirmed that the engine has completely failed and had loud knocking sounds, but they are attributing the issue to an external leak in an attempt to deny coverage under Safety Recall SC209. The manufacturer (via the…”
“The vehicle has experienced intermittent stalling and near-stalling while driving. The problem began after a prior Kia engine replacement related to DTC P1327/P132700. After the engine replacement, the vehicle developed additional drivability and warning-light concerns, including P0420 and communication/CAN faults. An authorized Kia dealer later documented that the vehicle had stalled a few times, identified P0420, reported a clogged catalytic converter, and found 11 additional lost-communication/CAN-related codes. The dealer stated that approximately eight additional diagnostic labor hours would be required to investigate the remaining faults. The vehicle was returned with the intermittent stalling condition unresolved. The stalling presents a safety risk because the vehicle can lose motive power unexpectedly while being driven. The vehicle remains available for inspection. The dealer confirmed the stalling complaint and performed diagnostic testing, but the complete cause has not been determined. Kia previously performed an engine replacement related to the earlier P1327 condition, and the current stalling occurred afterward.”
