A deviation may develop between the internal temperature and sensing temperature of the ICCU (Integrated Charging Control Unit) during high-current AC charging and predominantly in cold weather environments. If this condition occurs, the ICCU may become damaged, resulting in a stopped charging session and inability to charge using Level 1 or 2 AC chargers; however, the EV battery can still be charged using Level 3 DC fast charging.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10249469-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10249469-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10249469","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"KIA","model":"EV9","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_kia_ev9"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
