The speed limit is announced when the vehicle is unlocked and a door is opened (waking up the CMU) without touching the start button. This concern occurs on the vehicles located in Canada and Mexico including those driven to and from the U.S. It is caused by improper CMU software and the unnecessary speed limit announcement function left activated at the factory. To correct the concern, the CMU software has been modified and the speed limit announcement function has been removed.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10163382-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10163382-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10163382","components":[{"id":"electrical","name":"Electrical system","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.
