2013 F-150 subject to Customer Satisfaction Program 19N01, Transmission Molded Leadframe Extended Coverage. Speedometer went to zero, airbag light illuminated, truck downshifted on its own with a sudden lunging feeling, as if I got rear ended. Wrench icon illuminated. Truck would not shift properly. Mileage indication went blank. I was doing 55 mph on the highway with other vehicles around me. Caused me to have to make an abrupt stop and almost caused an accident. Definitely put my safety and others at risk. Problem happened 3 times during my 1 trip. Was able to correct by turning vehicle off then back on. Can be reproduced easily. Not confirmed by dealer or maintenance tech, or inspected by anyone because I am afraid to drive it. There were no warning signs or symptoms before problem occured.
