Dash lights up with errors

My 2018 Acura TLX, sh-awd 3.5 litre. As of late comes up with three errors/issues all at once. It says sh-awd problem, battery charging problem, idle auto off problem. They all come up exactly at the same time. It happened before but when I restarted the car it would be gone. Now it doesn't seem to clear itself, has anyone had this issue?

Suggest to start by checking the battery - many such problems are linked to the battery. If the battery is more than 3 years old, consider replacing it.

I tested the voltage at the battery after the car was on, with some load on the battery.
And then also tested the voltage at the alternator itself. There were both at around 14.2

​​​​​​Is there more I can do test the alternator?
