What are the defects?
Due to a software issue, the Powertrain Control Module (PCM) and Battery Energy Control Module (BECM) may impact the hybrid battery assist function. As a result, the driver may be unable to restart the engine.
In Addition, due to a software issue with the Dash Electronic Supply Unit (Dash-ESU), when the hybrid system is powered on multiple warning messages may display in the instrument cluster:
• the engine warning light may illuminate;
• the instrument cluster may fail to illuminate the visual and audible seat belt warnings; and
• the 360° view camera functions may not operate as intended to assist the driver to detect nearby obstacles or driver errors.
• The clutch connecting motor and engine may not engage with appropriate timing when:
- restarting the engine during EV-driving and/or
- the engine may restart immediately after the transition from engine-driving to EV driving.
In this condition, the engine RPM may not increase, and the engine may fail to restart. The engine can be restarted by pressing the “push start button”.

What are the hazards?
If the engine does not restart from i-stop and a loss of safety systems such as camera functions and seat belt warnings it may increase the risk of an accident, causing injury or death to vehicle occupants and other road users.
What should consumers do?
Owners of affected vehicles will be contacted by Mazda Australia once the remedy is available asking them to book an appointment to update the PCM, BECM and Dash-ESU with a revised calibration, free of charge.
