Service bulletins for the 2020 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.

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

SA-031-20j2020-12-04. Service bulletin. LATCHES/LOCKS/LINKAGES:DOORS:LOCK; EQUIPMENT ADAPTIVE/MOBILITY; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:SOFTWARE. IMPORTANT NOTE: Some 2020 Mazda3 vehicles may have incorrect infotainment software version 10042 installed. The incorrect software will cause MyMazda App Connected Vehicle enrollment errors. Go to SSPC1. Some customers may complain about any of the following: Infotainment Center Display does not provide the Authorization Code during the MyMazda App Connected Vehicle enrollment (and Software Update Error message on 2020 Mazda3 only). Remote function(s) inoperative. Engine Start / Stop, Door Lock / Unlock, Lights ON / OFF
16-002-20-37222020-08-04. Service bulletin. ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:DOORS:LATCH; EQUIPMENT; ENGINE. When the vehicle is in sleep mode, some customers may experience a failed remote control attempt using the MyMazda APP, however, the second attempt works fine and no DTCs are stored. Remote control functions: - Remote Engine Start/Remote Engine Stop - Remote Door Lock/Remote Door Unlock - Remote Hazard Light. This concern may be caused by improper telematics communication unit control software. To eliminate this concern, the telematics communication unit software has been modified
09-024-20-37022020-08-04. Service bulletin. LATCHES/LOCKS/LINKAGES; EQUIPMENT ADAPTIVE/MOBILITY. Some customers may complain that the rear console lid does not slide smoothly. This may be caused by improperly positioned felt pads attached to the rear console lid lock, which may have moved out of position after repetitive use. The exposed adhesive residue may stick to the rail and disrupt smooth sliding operation. To eliminate this concern, the felt pad positions have been changed.
09-017-20-37012020-05-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; LATCHES/LOCKS/LINKAGES; ELECTRICAL SYSTEM. Some customers may experience that the door locks may not operate using the touch sensor on the outer door handle while parked in a parking space surrounded by concrete walls, but will operate when using the remote transmitter. This concern may be caused by refraction and/or diffraction of the signal used for the advanced keyless entry system by the steel reinforcement bars in the concrete walls. As a result, the signal will resemble a theft attempt (known as a Relay Attack) and the anti-theft function of the advanced keyless entry system will prohibit door lock operation. To eliminate this concern, the LF control unit software has been modified to reduce the improper detection of the theft attempt.
09-016-20-36932020-05-04. Service bulletin. LATCHES/LOCKS/LINKAGES; ELECTRICAL SYSTEM. Some customers may find that they cannot lock their vehicle when using the touch sensor (shown below) on the front door handle, however, they can unlock the vehicle. This concern may occur after the vehicle has been recently washed and water has accumulated around the touch sensor, resulting in temporarily lowering the sensitivity of the capacitor sensor. To eliminate this concern, the shape and material of the rubber sheet attached to the touch sensor has been improved.

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