Question for car people, lol...

Waiting for it to be towed right now, but for you car MD's, here are the symptoms:
-Starts right up and sounds just fine but won't come out of Park.
-All the warning lights are on and won't turn off, including the parking brake even when the parking break is disengaged.
-Yet other stuff won't turn on at all, like the radio, A/C, etc., even though it'll sit there running just fine.
Now the battery was just replaced after dying for pretty much no reason we could tell, the car is only 1.5 years old... any of this maybe related to that somehow? What can drain a battery besides leaving a light on, etc? Sound like a computer/electrical prob?
Obviously I'm bored passing time waiting, so any of your guesses, lol.
