This concern occurs when turning the ignition on or starting the engine when the battery is at 8 volts or lower (vehicle is in sleep mode), then it is charged to normal voltage while connected to the vehicle. NOTE: This concern will not occur if the battery is charged when removed from the vehicle. This concern is caused by improper telematics communication unit control software. To eliminate this concern, the telematics communication unit control software has been modified.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10182108-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10182108-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10182108","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-30","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_mazda_cx-30","2021_mazda_cx-30"]},{"make":"MAZDA","model":"MAZDA3","year_from":2019,"year_to":2021,"match":"exact","vehicle_ids":["2019_mazda_mazda3","2020_mazda_mazda3","2021_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
