Well my 2017 is in the shop waiting parts. My 12 volt battery died and apparently took out high voltage relay. 7-10 days for parts to arrive. Gave me a new Equinox as a loaner. Within 10 minutes I really miss my car! If anyone would just take an EV for a spin they would realize what a crappy car an ICE is.

That would have to be a pretty catastrophic battery failure to take out a relay. Would take a large surge of amps (like a dead short) through the coil of the relay to fry it. Yikes! Maybe you can ask how his could happen and report back.

That sucks. And the Equinox is a decent car, but you’re right, it’s an ICE and I can definitely see where you’d miss the Bolt.

Sounds like two unrelated incidents. Let us know what happens
I wonder if the "high voltage relay" referred to is one that supplies power to the inverter - if it failed and the car was running its low voltage systems off nothing but the 12V battery that would explain both failures.

I believe that is what happened. Will get full details when repair is done. Also the seats in the Equinox suck too....
