They've not learned from past issues, I have a Lexus hybrid from 2008 and a known issue with them is that the 12v battery will die if the car is left to sit for more than 2 weeks.
Reading the article it seems like the problem has gotten much worse as the new EVs rely on the 12v batery for more electronics.
I've had the car 3 years and I'm on my second battery. If they dig into this properly it will go back a lot further than the 20s.
