Having similar issue, 12.2V after few hours from turning car off, car is just 2 years old. Doing regular daily commute of totally ~1-1.5hr of suburban/urban driving to work and back. Always comfort mode, start-stop deactivated.
No any issues so far, but wondering when temps go into -10C or lower in month or two, will the car start with such low SoC.
During drive, voltage is between 14.7 and 14.9V, so alternator seems to be working OK, however not sure with how much current is it charging... And if all working correctly, why so low battery voltage and SoC?
