Official summary
Some customers may experience that after the doors are locked and the Fuel Door Lock Delay with MAZDA CONNECT has passed (default setting is 90 seconds), the fuel-filler lid does not lock and can be opened when pressing it. NOTE: - The fuel-filler lid does not lock immediately after the doors are locked, but after the time set in the Fuel Door Lock Delay (0, 30, 60, 90, and 120 seconds). - Although the root cause has not been identified, the vehicle should be repaired by adjusting the fuel-filler lid opener cable position when there is a customer complaint.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
