I have suddenly lost all power to my 2010 Mazda 3. No

Customer Question

I have suddenly lost all power to my 2010 Mazda 3. No response to key fob, nothing when key is turned. I suspect a fuse issue, likely a main fuse since all power is gone. Any suggestions on which fuse has this kind of influence on all power?

Additional details on this issue:
• Have noticed no issues at all lately, smooth running and no signs of issues with electrical or other systems
• Battery is about a year old; still looks great (no corrosion)
• I ran a bunch of errands today, but each a few miles apart and no A/C use or other possible drains on power
• Total blackout of power and no reaction whatsoever when trying to start car; no sound or lights at all
• Have checked all minor fuses (7.5 – 25) in main fuse compartment under hood and they appear fine. The others are larger and harder to remove, so I’m hesitant to blindly start pulling since I suspect some are hard-wired to actual fusebox.
