Mazda dash supply unit may disable defroster and other startup functions

Mazda is recalling certain 2024-2025 CX-90 and 2025 CX-70 vehicles with a Dash Electrical Supply Unit because the defroster, seat belt warning, 360° view monitor and PHEV battery cooling may not work at startup.

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: Rubric level 3 covers risk-of-harm where injury has not yet been reported: several auxiliary functions may not start correctly, but the vehicle retains control and propulsion and no incidents are recorded.

Plain-English summary

Mazda North American Operations is recalling certain 2024-2025 CX-90 and 2025 CX-70 vehicles equipped with a Dash Electrical Supply Unit (ESU). About 80,915 units are potentially affected.

During vehicle startup, the defroster, seat belt warning, 360° view monitor functions and the PHEV high-voltage battery cooling system may not function properly.
