A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

The manufacturer filed it against 4 model years: 2026 Kia Sorento, 2025 Kia Sorento, 2024 Kia Sorento, 2023 Kia Sorento. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
