Engine restart is possible with key operation. This problem occurs when an IR request happens during an extremely short period (a few milliseconds) while transitioning to i-stop control, such as when the brake is released. In this case, the engine may fail to restart due to improper i-stop control. This concern has been eliminated through a PCM control software modification.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11022616-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11022616-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11022616","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-30","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_mazda_cx-30","2023_mazda_cx-30"]},{"make":"MAZDA","model":"MAZDA3","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_mazda_mazda3","2023_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
