Had Toyota Road Side Assistance so off to the dealer it went. They got it started with a jump and then measured the battery and the charging system. It seemed to be fine, with the battery showing 12.41 volts when the car was off. But the tech was not satisfied and brought out an old "carbon pile" [as he put it] tester and the battery failed miserably, dropping to 8.3 volts under load.
In short, it "looked like" it was good until it was asked to do some heavy lifting at which point it failed. They replace the battery under warranty.
He also measured the 'no key in the ignition' current flow. It would bounce between 22ma and 26ma. The bounce was the security LED turning on and off.
As a side note, when I got the car back they had reset the clock to the correct time  .

Mines a 2015 as well, I ended up buying the battery someone suggested earlier in this thread and it's working wonders.
