This may be due to a software concern in the telematics control unit (TCU). Inform customers that Ford is currently working on a software update that will be released via an over the air (OTA) update expected in July 2021, and that the TCU software will update automatically if the vehicle has Vehicle Connectivity turned ON in the touchscreen Settings. Let the customer know they can continue to drive the vehicle, and contact the customer in August to determine if they received the update. If the customer needs further assistance with the update, schedule a follow-up appointment. Monitor OASIS for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10198655-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10198655-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10198655","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EDGE","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_ford_edge"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
