It seems when the car is driven about 1 mile from start point the Anti-lock brake light and the AWD disengage light luminate to notify driver of a problem. It is accurate because the rear wheels deliver no power when the light is luminated.

Hello, I'm Danny.

It sounds that you have fault codes stored in both the anti-lock brake system and the transmission- transfer case in the all-wheel dive system. This will cause the poor performance you are experiencing. The best thing for you to do is have a CAN scan- Controller Area Network performed to determine what fault codes are stored in your vehicle's computer. Here is a tutorial showing what is involved with a CAN scan:

Once you have this performed get back to us with the code numbers and we can then properly diagnose the issues your vehicle is having. Hope this helps and thanks for using 2CarPros.
