Once the software update is available, contact the customer and schedule a follow-up appointment for repair in February 2022. Monitor OASIS for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201605-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201605-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10201605","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_navigator","2021_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
