Hello Kitsube and welcome to our forum -
Sounds like you got a BIG electrical problem.
Is your car still under warranty?
When you left your car to "air out" for an hour, did you leave it running?
Did you check the two big fuses on the battery terminal?
If you have a volt meter, what does the battery read?
Did you clean the battery terminals?
I'd suggest you put your battery on a battery charger for a spell.
Come back.
