Electrical meltdown

Hi, I have a 2016 CX-3 sport. Today, with no warning, thr electrical system went bonkers. Engine light on, ignition light on, break light on. Fuel gauge failed. AC/Heat failed. Heated seats failed. Signals and lights went dead. Luckily I could drive it home, although the front windshield wipers were possessed and acting on their own the entire way (ironically the only thing working.) Had anyone had this happen? Any guidance on what it might be? Hoping the dealer can take it tomorrow. Its not safe to drive in it's current state. Thanks for the advice!

If it were my car, I'd start looking for a rodent nest or rodent damage to the wiring harness under the dash.

Other possible causes I can think of off the top of my head are a bad ground lug or weak battery.

I second the weak battery suggestion above. Check out this post :-


Answer was the battery was discharged due to the car not being used for around 3 weeks.
