2017 Ford Explorer. My advance trac light comes on (or) my advance trac comes on for no reason. Sometimes it won't let me drive. Today it made a grinding noise. Sometimes its on a straight road, sometimes making a curve at 10 mph. I've had this problem since I bought it. My mechanic just resets it, but its starting to get ridiculous. Can anyone help? Why hasn't Ford fixed this problem?
