This may be due to tire flat spotting. Dealers should refer to the all-new Pinpoint Test G located in the Workshop Manual (WSM), Section 204-04A, for help with diagnosing this condition. The currently available original equipment tire design has not changed. If flat spot occurrences continue after tire replacement, inform customers that driving the vehicle more frequently and minimizing the duration of time the vehicle remains stationary/parked will help to reduce flat spot occurrences. Returning vehicles with flat spot concerns must be diagnosed and repaired using Pinpoint Test G (referenced above). Engineering is investigating with the tire supplier and expects updates to be available in Q4 2025. Monitor Professional Technician System (PTS) for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019699-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019699-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11019699","components":[{"id":"wheels","name":"Wheels","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_ford_expedition"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
