Okay - In hindsight I guess it's obvious, but doing a full system reboot (hazard and left steering wheel button) turns off your outlet timers. Here's what happened to me today...

We have a 8-night work trip to northern Kentucky. Last night I packed the fridge in my R1S subtrunk with food we wanted to bring with us. Thankfully I plugged it into the 12V outlet rather than 120 (more on that in a bit). I turned on the outlets for 2 days (so I didn't have to worry about it) and went to bed. We left the house shortly after 5am this morning and roughly an hour into our trip we got this:

Why does shit like this happen ONLY when you're leaving on a long trip? Anyway, our R1S spent two weeks in the Malvern SC in January for the same issue and it hadn't happened again since we got Rosey back so I thought it was fixed. No biggie - we had a decent shoulder on the road, so I pulled over and did a full reset and we got back on our way. I didn't think at all about my fridge - just that we're going to be an 8+ hour drive away from home in a car that may give us issues.

At 6pm tonight, as we were getting our last charge of the day, I flipped to the energy screen to stop the charging and I noticed that the "Outlets" button wasn't highlighted (meaning that it wasn't on). I then had an "oh shit" moment when I thought that my fridge had been off since I did the full reboot twelve hours before. Thankfully, because I had plugged it into the 12V (which is automatically on any time you're in the car), the fridge was only off for about three hours while we had lunch and helped our daughter pack up some dorm stuff. Since it was full and set to 34 degrees, I don't think anything got too warm.

The fun on our trip continued as well. About five hours after the first issue, as I was crusing along using Driver Assist on I-70, I heard the dreaded "whoop-whoop, whoop-whoop" and a status message that "A system fault was detected". I didn't catch the message in a photo, but I did have two new icons at the bottom of the driver's screen:

Sorry it's so fuzzy...i was pretty frazzled at the time. The icon next to the headlights is a turtle and the right-most one looks like the drivetrain. It didn't ask me to pull over (although I did do the Capture Diagnostics) so I just kept driving. After I put it in park at our destination, the icons magically went away (no second reboot required). We had another 2.5 hours in the car after that without incident.

Anyway, the FM (yes - I have read it) tells you that if you want the 12V to stay on when you're not in the car you need to set the outlet timer. It doesn't tell you that a full reboot will turn the timer off. Maybe this will help someone else in the future.

Always has. Software updates turn it off too.

Resets, software updates, and low battery warning all turn off the outlet timer. So on a long trip just pulling into a charging station below 50 miles of range will leave you without power to the fridge.

The default I think is that the auto mode is on but the timer goes off. My mini fridge beeps when it turns on, so if I hear that when I get in the truck I know that the timer is off but auto is on. I stopped putting perishables in my fridge.

I don't think my 12v follow my 120v like the OP says. I will check if that changed in an update or if it is a change to the newer trucks. Mine is a 2022
