Does that mean my battery is dying? Is this also consider okay?
Also, the battery charger is in red again after only 3 mins of use of hidden menu system.
Thank you again.

Nominal voltage vs. state of charge is not necessarily relevant without the batteries temperature and composition taken into account. Our batteries are AGM type.
12.2v at 70F for example is going to be about 35-40% nominal state of charge.
Again, how old is your battery? If it is more than 4-5 years old it is likely dying. You can continue to waste time on something that will leave you stranded, or you can replace it with a new battery. Batteries are consumable maintenance items on these cars.
Make sure the replacement is of like kind and rating and register it with the vehicle.
