What is the battery voltage you guys have seen after leaving your car sit over night? Mine is usually around 11.2 - 11.4 seemed to be about the same even when it was warmer outside. I'm concerned there might be some problem and would just like to compare.
My concern started from every time I would hook a programmer up to the vehicle it will not let me proceed because the voltage has to be at least 12V. Not that it recommends I hook it up to a charger, it requires it. I've programmed lots of other vehicles and the recommendation is always there to hook it up to a charger but I've never had it not allow me to do anything until it's hooked to a charger.
When I drive the car, it goes right to 14.4V so I'm thinking it's probably not the alternator, most likely the battery just isn't holding the charge well. The surprising thing is it's a 2015, 3 years old and it's always been this way and I've never had a problem with the car starting, not even on the coldest winter mornings.
