The rear drive unit (RDU) in these vehicles uses a brushless DC motor to vary the amount of torque to the rear axle, and during functional verification, it produces a noticeable noise that is a normal function of the RDU. If the noise appears abnormally loud, it is recommended to compare the noise from the customers vehicle with a 2019 AWD Edge or Nautilus built before 22-Jan-2019 or after 03-Mar-2019, in a similar environment (i.e. both outside). If the noise in the customers vehicle is determined to be significantly louder than a similar vehicle built outside the build dates, do not disassemble the RDU for further diagnosis, an updated RDU assembly is available.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10160946-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10160946-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10160946","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EDGE","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_ford_edge"]},{"make":"LINCOLN","model":"NAUTILUS","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_lincoln_nautilus"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
