What the reviewed source says
Start with the documented condition, not a parts guess.
NHTSA campaign 24V814000 includes certain 2025 Mazda CX-70 vehicles. Mazda North American Operations (Mazda) is recalling certain 2024-2025 CX-90 and 2025 CX-70 vehicles equipped with a Dash Electrical Supply Unit (ESU). During vehicle startup, the defroster, seat belt warning, 360° view monitor functions, and the PHEV high-voltage battery cooling system may not function properly. An ESU that does not function properly, increases the risk of a crash.

Check the complete VIN before arranging work

Useful before authorizing work
Read the method beside the problem
These guides explain the safety and evidence checks that apply to this problem file.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
