Service bulletins for the 2021 Mazda CX-30

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

616 on file from NHTSA, as of 2026-10-19.

SA-020/232023-05-05. Service bulletin. FUEL SYSTEM, GASOLINE; FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY. Some customers will report that their fuel door was stuck closed and would not open to refuel the vehicle. Follow the repair steps below unless the conditions outlined in TSB 09-019/21 - FUEL-FILLER LID PANEL IS DEFORMED for 2019-2021 Mazda3 and 2020-2021 CX-30 are present.
09-006/222022-04-05. Service bulletin. LATCHES/LOCKS/LINKAGES; EQUIPMENT; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP. 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.
09-019-21-38132021-06-29. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY. Some vehicles may exhibit a deformed fuel-filler lid panel (1) attached to the fuel-filler lid box, resulting in a poor appearance. This concern is caused by the lid box not having enough water drainage capability which leads to the accumulation of water inside it. The water then freezes in cold weather and expands or the inner side of the lid panel absorbs the water and swells from long exposure, deforming the lid panel. To eliminate this concern, the shape of the fuel-filler lid box has been modified to have better drainage capability and a modified fuel-filler lid panel service part has been established for less water absorbance.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
