I have a 2021 RAV4 Trail (Adventure) with ~27000km. This is the 2nd winter since I have owned this vehicle, and I live in Manitoba, Canada where it gets very cold (colder than -30c/-22F) routinely. The battery in the RAV4 drains below 11 volts in less than 5 days unless I drive it every day for at least 30 minutes, or I put a trickle charger on it. The dealer says this is normal, however the following class action lawsuit has come to my attention. .

Have you heard anything of this, or of similar issues with 2020/2021 RAV4's?
By the way, it's bad enough I have to put a battery trickle charger onto my car battery every 3 days (if I don't run it) in cold weather. But, the NOCO Genius charger I purchased won't work in temperatures below -20C (-4F), and needs to be warmed up before connecting, then placed near the block heater.
