The V2X technology allows EV9 vehicles to interact with other devices such as Vehicle-to-Home ‘V2H’ and Vehicle-to-Grid ‘V2G’ technology which enables bidirectional charging, where the EV's battery can be used as a mobile energy storage unit, providing power to the grid or a home backup power source.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036137-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036137-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11036137","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KIA","model":"EV9","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_kia_ev9","2026_kia_ev9"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
