I have had to replace the 12v battery on my 2020 Focus with fewer than 20,000 miles. I have had the vehicle from new.
I had to replace the 12v battery on my EV, also owned from new, in December after it completely died at a similar mileage. Testing my 13 year old Volvo, no modem, no connectivity it pulls 20mA 2 hours after switching off. That car can sit for weeks with no issues. Both the connected 2020 cars pull 0.23 - 0.25mA (as tested though this can change if the modem is activated) when asleep and can drain the 12v battery in less than three weeks to the point the central locking will not work. If I leave anything plugged in (accessories such as dashcam, phone charge cable or wireless android adapter) the EV is dead overnight. It appears the ports do not shutdown if they detect something is plugged in. As an aside, I checked my Volvo this morning while out and about, the alternator output is 13.6v when driving, this increases to 14.5v on overrun. Confirms the AGM battery headroom overboost.
