2008 Ford F Super Duty Electrical system Problems

“Randomly and without warning a green wrench light came on my dashboard while I was driving on a busy highway. Date was 12/1/2015. I lost power and had to pull over on the side of the highway. There was no power when I tried to accelerate. There was no response when I would step on the gas pedal. It was idling very rough, I turned off the truck waited a couple of minutes then tried to turn the truck on again and the wrench light cleared. It went back to normal and I was able to drive off the highway. …”

“This truck has been an issue from the time we bought it. We have contacted Ford multiple times and their response is keep your receipts just in case. We have replaced the turbos both high and low end twice and they are starting to act up again. Traveling 60 MPH down the road you lose all turbo pressure causing you to lose power.
