My first thought is a bad body control module. It originally had a 4yr./50k warranty so you might still be covered. ---

Yes, a bad battery can produce odd effects and you can’t test other stuff until you take care of that. If you’re lucky that’s all that’s wrong. ---

I presume you’re saying the seat belt and airbag lights are lit during normal vehicle operation. If so, then you still have a problem. Could be a bad body control module, could be bad sensors. Either way your vehicle isn’t safe. Have a good mechanic look at it. ---
