Drive my 2018 Model S on Jan 2nd. Plugged it back in to charge that same day with main battery down to about 50% and target charge level set to 70%. Went to drive it last night and the 12v battery was dead. Jumped the 12v battery and when the computer powered on it showed the main battery at 70%.
thoughts? When does that 12v battery charge? Why would it ever die when the car is plugged in to an electrical outlet the whole time and the main battery is fully charged?
