Prius 2012 plug in - problem with the electrics

Hello, I have three problems, and they all seem related to each other.

1. When I press the buttons on the steering wheel, the wrong ones light up on the screen. For example, if I press the volume up (+) button, the trip button lights up.

2. The City EV and Eco Mode buttons on the center console don't work.

3. The battery status on the upper display (under the windshield) constantly shows one bar, even when fully charged.

The hybrid works properly, consumes low fuel, and is a pleasant drive, even on electric power.

Has anyone had this problem and can help me?
