2025 BMW Trunk/Tailgate Latch Not Locking SIB 51 04 25

BMW has issued Service Information Bulletin (SIB) 51 04 25 to address a potential issue with the trunk or tailgate latch on certain 2025 BMW models. This service action ensures that the trunk or tailgate properly secures after closing, preventing it from not completely locking.

The SIB 51 04 25 bulletin highlights a specific concern related to changes in the opening mechanism of the trunk/tailgate latch. This change can lead to situations where the trunk or tailgate does not fully engage and lock, posing a security risk and potential inconvenience for vehicle owners.

This means that if a new tailgate lock part is not immediately available, the dealer is obligated to inform you and schedule a follow-up appointment for the repair.
