2023-2024 Mazda CX-60 and CX-90 recalled in Australia

Yesterday at 07:52 PM

Mazda Australia has recalled 7930 examples of its 2023 to 2024 Mazda CX-60 and Mazda CX-90 models, citing a potential fault with the hybrid system which could result in the driver being unable to restart the engine. 

The affected vehicles are stamped 2023 to 2024 models, covering 6557 CX-60s and 1373 CX-90s. 

The recall notices, lodged with the Department of Infrastructure for inline-six petrol and diesel variants, say: "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 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'."

The latter concern has been noted for diesel variants only.

"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'.

"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.”

The CX-60 PHEV is also potentially affected by "improper programming" of the Dash-ESU, which could result in the following warning messages: 

• The engine warning light may illuminate;
• The PHEV high-voltage battery cooling system may not operate as intended. As a result, electric (EV) drive mode may not be available;
• 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.

"A loss of EV drive mode and a loss of safety systems such as camera functions and seat belt warnings could increase the risk of an accident, causing serious injury or death to vehicle occupants and other road users," said the recall notice for the CX-60 PHEV. 

A full list of vehicle identification numbers (VIN) for the 7930 vehicles involved in the recall can be found below:

• CX-60 and CX-90 3.3-litre turbo-petrol: VIN list

Mazda Australia advises it will contact affected vehicle owners when the remedy becomes available to book an appointment to have the PCM and BECM updated (inline-six), and the Dash-ESU for all models, with a revised calibration, free of charge.
