Recalls: Mazda KK CX-90

2023 Mazda KK CX-90: loss of power steering assistance

In January 2024, recall campaign R202401 was issued for 2023 Mazda KK CX-90 vehicles. Due to a manufacturing defect, the gear set within the power steering assembly may not operate as intended. As a result, the driver could experience unexpected increased steering effort. Unexpected increased steering effort, if it occurred whilst driving, could increase the risk of a collision and injury to both vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-005882.

2023 Mazda KK CX-90: autonomous braking falsely activated

In May 2024, recall campaign R202404 was issued for 2023 Mazda KK CX-90 vehicles. Due to a calibration issue within the Vehicle Control Module (VCM) and when driving at low speeds, the vehicle may falsely detect reflective objects such as metal walls, barriers or similar objects on the side of the road as an approaching object. This could trigger an unintended brake activation that increased the risk of a collision and injury to both vehicle occupants and other road users. To fix, the Vehicle Control Module was to be updated with a revised calibration by a Mazda Dealer. For the VINs of the recalled vehicles, please see REC-005973.

2023-24 Mazda KK CX-90 Diesel: no drive when accelerator pedal depressed

In August 2024, recall campaign 202405 was issued for 2023-24 Mazda KK CX-90 vehicles with diesel engines. Due to a software issue in the transmission control module, if the brake pedal was firmly depressed to stop the vehicle, the clutch for the engine and electric motor may remain disengaged during deceleration. If this occurred, power from the engine or electric motor may not be transmitted when the accelerator pedal was depressed. This condition could increase the risk of injury to vehicle occupants and other road users. To fix, a Mazda dealer was to upgrade the calibration for the transmission control module. For the VINs of the recalled vehicles, please see REC-006046.

2023-24 Mazda KK CX-90 Petrol Turbo: system malfunctions due to Dash-ESU software

In November 2024, a recall was issued for 2023-24 Mazda KK CX-90 vehicles with turbocharged petrol engines. 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 engine idle stop (Mazda’s “i-stop”). Furthermore, improper software programming of the Dash Electronic Supply Unit (Dash-ESU) could cause multiple warning messages to display in the instrument cluster when the hybrid system was powered on. For example,

• the engine warning light may illuminate;
• the instrument cluster may fail to illuminate the seatbelt warnings, and the audible warning may not sound; and
• the 360 degree view camera may not operate as intended to detect nearby obstacles or driver errors.

If the engine did not restart from i-stop or there was a loss of safety systems and seatbelt warnings, it could increase the risk of a collision and injury to vehicle occupants and other road users. To fix, a Mazda dealer was to update the PCM, BECM and Dash-ESU software with a revised calibration. For the VINs of the recalled vehicles, please see REC-006173.

2023–24 Mazda KK CX-90 Diesel: powertrain and instrument systems software may affect hybrid function

In November 2024, recall campaign REC-006174 was issued for 2023–24 Mazda KK CX-90 Diesel vehicles. Due to a software issue, the Powertrain Control Module (PCM) and Battery Energy Control Module (BECM) may affect the hybrid battery assist function, such that the driver may be unable to restart the engine. Additionally, a software issue with the Dash Electronic Supply Unit (Dash-ESU) may cause the following problems when the hybrid system was powered on:

• illumination of the engine warning light;
• the instrument cluster may fail to illuminate the seatbelt warnings, and the audible warning may not sound;
• the 360 degree view camera may not operate as intended;
• the clutch connecting the motor and engine may not engage correctly when restarting the engine during EV-driving, requiring the driver to restart the engine by pressing the “start” button; and
• the engine may restart immediately after the transition from engine-driving to EV-driving.

If the engine did not restart from i-stop and there was a loss of safety systems, the risk of a collision would increase, as would the risk of injury to vehicle occupants and other road users. To fix, the PCM, BECM and Dash-ESU software was to be updated. For the VINs of the recalled vehicles, please see REC-006174.

2023-25 Mazda KK CX-90 3.3 SkyActiv-G: Body Control Module and faulty fuel level reading

In September 2025, recall campaign R202504 was issued for 2023-25 Mazda KK CX-90 vehicles that had 3.3-litre SkyActiv-G petrol engines. Due to a software programming issue of the Body Control Module (BCM), the instrument cluster may not operate as intended. This could result in an incorrect display of the fuel level, such that the driver may not be aware when the fuel tank becomes empty. If the fuel tank became empty whilst the vehicle was being driven, it could cause a sudden loss of power. This condition increased the risk of a collision and injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-006434.
