Hi I was very lucky to receive one of the first new models last month.
My Koba is amazing- as have all of my previous Toyotas. However in answer to your question it does not automatically lock the doors when you engage Drive or when you reach a preset speed. I am very disappointed that with all of the electronic devices and safety features and the approximately 20% increase in price over the last model that Toyota Australia has left a very important safety feature out of the vehicle. We see cars being carjacked almost nightly on the news. My knowledge of technology in this sector is limited but surely it is only an update of the operating systems to fix this.
The new model is a beautiful car- your wife should still buy one.
