The tech told her that since the vehicle was AWD the 3 remaining tires needed to be replaced. The tread life on the other tires were above the min’s ( estimated 5 to 7/32’s). I asked the tech why the replacement requirement. He stated that given the tread difference between the old tires and new one the AWD system would not perform correctly and over time would adversely affect the functioning of the system which will also lead to very costly repairs. Again, not knowing much about the AWD system I found this info very interesting. Is this true or false? I do recognize if this situation existed on a RWD car there will be some handling differences but it would not necessarily adversely affect the [long term] driveability of the car (non-track situations).

Yes, this is true. Not sure of the exact diff before you would have issues, but they need to be the same!!!!
