## 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
