Ok so all of a sudden I turn on my car and first off my airbag light is blinking. Then I go to turn on my AC and nothing happens. So I start playing with the buttons and hardly anything is working. I have absolutely no HVAC controls, none of those buttons do anything. The radio works but only the volume knob is working and I have to change the stations and everything else with the steering wheel controls. The navigation works but none of the buttons for the Nav work either so I have to use the steering wheel controls for that too. The screen is stuck on the Nav map and will not change. The lights for all the buttons that are not functioning do work. If anybody had any idea what the hell is going on please let me know, any help is appreciated.

Normally these things are diagnosed by Dealership at least thru the first 4 years. [Smart peiople buy the 7 year Nissan 100k extended warranty especially for electronics].

Hopefully you've gotten into HABIT of visiting the Dealer at least every 90 days [oil change] so that things under warranty can be found and quickly resolved.

Obviously parts will have to be replaced

Has your battery or alternator gone bad? What's the voltage measured across the battery terminals with the engine off (S/B 12.0v) and with the engine running (S/B 14.1 or so)?

12.0 volts with engine off IS A SEVERELY DISCHARGED BATTERY!!!!! 12.6-12.8 shows a fully charged battery at rest.

Ditto on the dealership suggestion. If, by chance, you're very far from the closest dealership I would try disconnecting the negative battery cable and see if you could possibly reset something.

Newer vehicles are very confusing for those without a BSEE or BSCS, as electonics make up much more than powertrain in build cost and repairs.
Electronic things don't get repaired, just replaced as few have the necessary diagnostic capacity to do circuit board repairs unless some minor cable conditions become known.
