For Mazda6 and CX-5, the following error messages may appear in the instrument cluster. • Front camera sensor system malfunction • Forward Smart City Brake Support Malfunction • Driver attention alert system malfunction. This may be caused by the battery voltage falling and the EPS control module failing the initial learning for the steering center position while cranking. The FSC detects the error notified by the EPS control module. To correct this concern, the control software of the EPS control module has been modified while the repair procedure modifies the FSC for earlier repairs in the market.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10182100-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10182100-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10182100","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"driver-assistance","name":"Driver assistance","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"steering","name":"Steering","parent":null}],"codes":["U0420"],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-9","year_from":2018,"year_to":2020,"match":"exact","vehicle_ids":["2018_mazda_cx-9","2019_mazda_cx-9","2020_mazda_cx-9"]},{"make":"MAZDA","model":"MAZDA3","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_mazda_mazda3","2018_mazda_mazda3"]},{"make":"MAZDA","model":"MAZDA6","year_from":2017,"year_to":2020,"match":"exact","vehicle_ids":["2017_mazda_mazda6","2018_mazda_mazda6","2019_mazda_mazda6","2020_mazda_mazda6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
