By Samuel Irvine · 15 Nov 2024
Mazda has recalled a total of 7870 examples of its Mazda CX-60 and CX-90 vehicles in petrol, diesel and plug-in hybrid guises, built between 2023 and 2024, due to malfunctioning software that may impact the cars' critical driving functions.According to a recall notice published by the Australian Government’s Department of Infrastructure, Transport, Regional Development, Communications and the Arts, 5331 petrol and diesel mild-hybrid variants of the CX-60 and CX-90 have been affected.The notice read: “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 engine may not automatically restart after entering idle stop (i-stop).“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 notice read.Unique to the diesel variant, the notice said: “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’.”In the worst case scenario, the notice said: “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.”The software issue impacting 2539 examples of the plug-in hybrid CX-60 is slightly different and only pertains to the vehicle’s Dash-ESU, which may also cause several warning messages to illuminate or systems to malfunction due to improper programming.The notice said: “the engine warning light may illuminate; the PHEV high-voltage battery cooling system may not operate as intended.“As a result, 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.”As with the petrol and diesel variants, in the worst case scenario, there are concerns a loss of EV drive mode and safety camera system functions and seatbelt warning malfunctioning could lead to serious injury or death.Owners of the petrol Mazda CX-60 and CX-90 built between 2023 and 2024 can check if their vehicle is affected here, while owners of diesel variants can check here.Plug-in hybrid owners can check here.All owners will be contacted by Mazda Australia imminently to arrange a time to have either vehicle’s PCM or Dash-ESU systems, or both, recalibrated free of charge.
