I have discovered that the Pro-Pilot and Auto Steering features on my new (less than 1000 miles) Armada are dangerous. I will not use either one again. Three time the Auto Steering tried to turn me into the on-coming lane of traffic. The Pro-Pilot would not hold the speed to which I set it. I was driving on flat roads and it was set for 55. The speed would "wander" with out ANY input on my part. The speed would be up to 65 and the back down to 55 and then back up gain. I finally turned it of when the Pro-Pilot had my vehicle going 70!
