2017 Fiat 500e electrical problem

[ConstanceWUWU]

Major headache with my 2017 Fiat 500e. Within the past week, I've had the power steering light come on, followed by warnings for regenerative braking, electronic stability control, and hill start. To top it off, both my brake lights and a headlight went out.

I'm starting to think it's an electrical issue rather than all these components failing at once. Has anyone else experienced so many problems at once? I'm hoping it's something like a relay that I can fix myself instead of having to shell out a fortune at the dealer. Any advice or suggestions please?

First off, take a good look at the 12V battery. And seriously, don’t forget to unplug that humidity sensor if you haven’t already. It’s like the troublemaker of the 500e, always stirring up chaos with the other systems.
