Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and Thank you for choosing Just Answer.
The newer Expeditions, Navigators and F150 vehicles are known for the wrnech light to come on in the dash. What I have found with most all of them is a faulty Electronic Throttle Body or ETB. The internal electronics go bad and it will cause all kinds of driving and accelerating concerns. I beleive this is what your dealer is reffering to and I would agree with them. Hope this helps.
