Manufacturer summary

Original wording in English

Some 2021-2022 Mustang Mach-E vehicles may exhibit a condition of intermittent headlamp operation while the vehicle is OFF and have diagnostic trouble code (DTC) B1533 stored in the body control module (BCM). This may be due to the internal logic within the headlamp switch. Switch and/or module replacement will not resolve this condition. Headlamp operation is not affected while the vehicle is ON. A new headlamp switch is currently under development to correct this condition. This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and schedule a follow-up appointment in July 2023, when parts are expected to become available. Follow up with the customer to confirm the appointment once OASIS is updated with the repair information.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
