Service bulletin 16-002-20-3722

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.

NHTSA's summary

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
