Today it failed to charge again so I headed to the dealer.
Of course the service writer and the EV technician then watched as it charged fine on the big Leviton while blaming my Schneider and the small Leviton and Clipper Creek at work are not compatible.
Just frustrating so back to work.

Did not charge again... pushed the extended setting and voila it starts charging. :|

Tonight I tried Entune app. Response 'battery too low to run pre-climate' Battery is 70+% when I pulled in. Start charge function just failed. Contactor just closes and opens and it fails to start.

It is a slow torture of intermittent failure. Eventually it has to get so dead Toyota will find something. Appointment for next Tuesday.
Good luck

Just measured the 12v draw when the car appears asleep. Close to 2 amps. Holy cow I had no idea.

Has anyone else checked whether that's a normal draw? I'll try to take an ammeter to mine tonight if I remember, and perhaps compare to the Leaf. However 24W doesn't really seem like that much...

Hmmm. If you leave your car off for 10 days, then that 24 W draw uses nearly 6 kWh of energy. That seems like a lot to me.

The 2 amps must be when the car is not completely sleeping. It takes a couple minutes for all the activity to die down. I suggest measuring it again, or even putting a data recorder on it to measure the current every second for an hour. If you don't have a data recorder, just make a video showing the multi-meter reading for 5 or 10 minutes.

Yeah, also it's worth noting that when you simply approach the car with the key in your pocket it "wakes up", and even without the key something similar happens if you're opening doors to pop the hood and such, so you'd need to set up some sort of remote or persistent monitoring and check in at multiple time points to get a sense of what the car's doing. And we still need some baseline data from others with normally functioning cars.

Left the hood up last night in the garage. Keys are 30' away in the house.
12 volt draw was measured at just over 2 amps in the morning.
Measured with Fluke 325.

Is this normal?

That cannot be normal. There was another owner who was having troubles like yours and his dealer found that there was something defective in his car that was pulling more power than it should when the car was off. I think they changed the NAV head unit and the problem was gone. You could start pulling fuses one by one and see when the current goes down.

More testing this morning after sitting overnight with the 12v battery charger.

In the morning the car was still pulling 2 amps continuous from the battery.
The two fuses that seem to reset the power draw to near zero are:

#9 G/W-B 10A Multiplex communication system
#10 RADIO 30A Audio system

as listed in the owners manual page 389.

When these fuses are replaced the draw stays near zero. Center screen reboots when the car is started. Car then continues to draw 2 amps again after settling down. Pulling the fuses again resets the draw to near zero. I need to take it in and explain this issue although I can see their eyes rolling already with another crazy customer that thinks they know something.

Any tips to tell the dealer please let me know.
I have in my mind there are more issues but one thing at a time.

Dropped off at Carson today.

Dealer calls back my new 12v battery is bad. Does not pass load test.
Really? The car is killing the battery is the reason the car is in.
How about charge and retest?

Nooooo, Toyota must replace my three week old Bosch 24 at my cost. No more warranty.

We exchanged a few words.

How do you stay polite in such events ?
I have such a hard time dealing with willingly not even trying to understand the situation.
Now you have to buy a new battery from them.
It will get killed within a month.
Your car will be stranded _again_
tell them you want to be reimbursed for all the time/trouble you will go through because of this unnecessary checking from their part.
argghh... i feel for you.
