2023 Model S Plaid High Voltage Relay - Every 1 minute???

Hello!

On my new Model S, parked in the basement, about once per minute I can hear the HV relay "ka-thunk" whether plugged in or not, anybody else experiencing this?

No, it shouldn't be doing that. Does your battery charge to 100% full, and what does it show for miles remaining when/if it does?

I did a hard reboot and it hasn't happened since.

Maybe the dc-dc converter needed to be reset. The main traction battery has a standby supply that bypasses the main contactor to run the systems when power requirements are lower. If the dc-dc converter was in a weird state and not using it and just running on the accessory battery, the contactor would engage every so often to recharge the accessory battery.

That sounds a bit odd, - has that happened to anyone else?

It happened to me on my P85D (frequent contactor action) but it went away. When I opened a ticket for it, Tesla said it was some kind of software bug and it would be fixed soon. Probably standard response, but it did go away not long after that.
