12v battery (hybrid) runs low after sitting for a week

Likewise I won't leave home without a jump pack at this point.

Same. This issue alone is causing some pretty big pangs of regret in regards to this truck…..the deaf ears of the dealership is most maddening.

Half considering a hood mounted solar battery tender for piece of mind. I don't do long through hikes anymore but its crazy to think that I wouldn't have been able to leave my truck at one end of the John Muir Trail while i hiked it.

It's the original battery. I've circled the voltage of me driving.

Thanks, something in the charging system seems wonky If it’s sometimes applying 13.8v and other times not. Also seems like a lot of drawdown overnight - logout of the Toyota app to rule that out as a source.

Given that some like yourself have an issue, and other people don’t, it suggests a faulty component or something.

I’d push hard on the dealer to find what’s wrong. Hopefully you can get it sorted. If it were me and they gave a BS excuse, I’d start documenting what would be needed for a lemon law case.

I've got a laundry list for the dealer when I have the time to burn. The OBD2 port falls out because the dealer replaced it with an aftermarket tracker, back passenger tire leaks super slowly, no punctures. And an annoying rattle with the trim in front of the front doors as identified in this thread. Rest assured I'll keep them busy one way or another.
