2012 Ford Expedition Electrical system Problems

“Our 2012 Expedition speedometer has repeatedly dropped to zero and stopped functioning while driving on the highway. We bought the truck last month as a Ford certified vehicle. It has 30k original miles. This is a major safety issue. We have also submitted a complaint regarding intermittent loss of transmission output.”

“While driving, the vehicle suddenly downshifted into 1st gear, rpms revved up, speedometer stopped working, pushing the gas pedal temporarily had no effect, fuel level low light came on and tire pressure sensor fault light came on. I was still able to drive the vehicle, though the speedometer was not working. I stopped, turned off the vehicle and restarted it and the vehicle worked fine. This event happened three times over the past month. Sheehy Ford in ashland, virginia said that I needed a new lead frame and that the charge would be $900. …”

“Vehicle downshifts while driving at different speeds. Panel reads, flat tires, no fuel, no gauges will work. I was pulling out of a gas station on a major hwy, I gave the vehicle gas to enter the lane, as I was approaching a higher speed , my vehicle downshifted and the vehicle behind me had to slam on their breaks to avoid hitting me in the back. Another time at a high rate of speed on an interstate , as I was switching lanes, my vehicle downshifts almost causing another wreck. If it had not been for car seats, my grandchildren would have hit the floor. …”

“We took the vehicle to our local Ford service center approx. Aug. 2017 with mileage at approx. 54000 miles while the vehicle was still covered under factory warranty. We were experiencing a sudden downshift in the transmission when driving in city streets. The instrument cluster would show the speed at 0 MPH and the message --- miles to empty would display. The dealership was not able to pull any codes at that time or duplicate the symptoms on the vehicle. Our VIN was not covered under any recall. We were not charged. No check engine light has ever displayed until april 5th, 2018. …”

“Driving down the highway at 65 MPH in the left lane when the car lost all power. We were able to coast to the side of the highway because we were traveling at the rate of speed listed above with no power. This is extremely dangerous to someone in this position. As we attempted to see if we could figure out what had occurred an error appeared on the service display of service advance trac. A few minutes later we noticed the additional code of tire pressure monitor fault. We had to get the vehicle towed at this point. Not satisfied as the could be huge safety issue.”
