In my experience many dealers and manufacturers tend to be really crappy when it comes to honoring their EV warranties.

I would still double check the 12v battery first, as it’s possible that this is just a super simple easy fix.

having level 2 charging is a nice convenience. Higher voltage is actually more efficient than lower voltage.

Worrying that the 240v wiring in your house is going to “create a giant magnetic field and give you cancer” is an absurd thing to worry about, whether you have a car charger in use or not.
