Okay. Who HASN'T had a 12V battery issue with their 2023-24 Prime?

You have been saying the same thing for Gen 4 for many years now.

 

Agreed. There was a serious discharge problem with gen 4 for some owners, same as gen 5.
It’s like the gen 3 head gasket issue, some have it and some don’t, but no one knows the cause

 

And just like the 12-V-battery issue, the Gen 3 head-gasket issue was due to owner error. If you trash your engine while you drive it, don't change the coolant, etc., don't expect your head gasket to last forever. Likewise, if you use the ACC mode, keep the lights on when the car is not in the ready mode, don't do frequent long trips, keep the car plugged in when not needed, etc., don't expect the 12-V battery to survive for too long.

 

You’re making wild assumptions and accusations in both cases without any evidence

 

i realize, many think they know

 

Toyota might.

Our third gen's battery more-or-less living on a smart charger, will be 9 years old in september. Load tests like new still. I kinda wonder if I quit with the charger, it'd be like the proverbial Portrait of Dorian Grey.
