The vehicle may be unable to enter electric-only drive modes as expected during normal drive cycles. This may be due to the software within the belt integrated starter generator (BISG). For vehicles with this condition, follow Pinpoint Test G located in the Workshop Manual (WSM), Section 303-06D and repair the vehicle as necessary. Note that the BISG is on backorder status at the time of this publication and Ford is working to make parts available. Engineering is investigating this concern. Monitor PTS for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031640-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031640-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11031640","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":["P0A1E"],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2026,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer","2023_ford_explorer","2024_ford_explorer","2025_ford_explorer","2026_ford_explorer"]},{"make":"FORD","model":"EXPLORER HYBRID","year_from":2020,"year_to":2023,"match":"base","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer","2023_ford_explorer"]},{"make":"FORD","model":"EXPLORER HYBRID","year_from":2025,"year_to":2026,"match":"base","vehicle_ids":["2025_ford_explorer","2026_ford_explorer"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2023,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
