The concern occurs only once after the vehicle is in sleep mode (5 minutes or more after the doors are locked). This is caused by improper control logic of the electrical supply unit (ESU). To correct this issue, the ESU software has been modified.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10170933-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10170933-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10170933","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"lighting","name":"Lighting","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"MAZDA3","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
