What's wrong?
The Dash Electrical Supply Unit, or ESU, on the 2024-2025 Mazda CX-70 and CX-90 is an electronic control unit tied to dashboard and startup functions. It helps power and coordinate systems the driver depends on right after the vehicle wakes up, including the defroster, seat belt warning, surround-view monitor, and the PHEV high-voltage battery cooling system.
On affected vehicles, the ESU software was programmed incorrectly. During startup, that software error can keep those connected functions from working properly. The issue is not a broken switch or loose trim panel; it is a control-module software problem. Mazda's remedy uses improved software for the ESU.
When the hybrid system is powered on or the engine is started, owners can see the malfunction indicator light and warning messages in the instrument cluster. Those dashboard warnings are the sign that the ESU startup error is present.
