2004 Sorento 4 wheel drive. We have been having issues with car not starting on 2004 Kia Sorento

We have been told it is the 4 wheel drive modgel that needs to be replaced? Battery is fine. Why would the 4 wheel drive model effect starting. We were able to jump for a while but now it will not start at all.
It feels like the it is stuck in park.
