2015 Ford Expedition power train problems

“I am driving a 2015 Ford Expedition that utilizes the 6R80 transmission. I am actively experiencing the severe, dangerous highway downshifting failure described in Ford's F-150 safety recall. The truck is throwing codes P0705, P0706, and P0707. My car will go into limp-mode and lose acceleration while driving, light up the wrench and stop displaying the gear and idle high and accelerate at half the speed. When I turn my car off, it will not turn back on until the engine has cooled off.”

“Issue I’m having with my 2015 Ford expedition Limited, is on multiple occasions when I’m at highway speeds my vehicle downshifts and decelerates. While im driving through the city streets, my vehicle downshifts randomly and does not upshift. On these occasions I’ve had to safely pull over and turn my vehicle off and on. Doing so resolves the problem for about 10 miles, and then back to the same issue.”

“Driving at 58 mph with cruise on, using the cruise - button to reduce speed to 50 the vehicle drastically downshifted causing the engine to over-rev and ultimately caused catastrophic engine failure, a blown engine.”

“Vehicle will shift in and out of gears randomly while driving I’m concerned about driving on the highway and getting into or causing an accident because it happens at random and then stops No lights on dashboard and vehicle just passed inspection I believe it is a problem with the TCM and there has been an extended warranty issues for the same part in different models for ford including the fiesta and focus I believe”

“The contact owns a 2015 Ford Expedition. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle briefly hesitated, with the transmission slipping. Later, the contact stated that while driving at 60 MPH, the vehicle was vibrating excessively. The check engine warning light was illuminated. The vehicle was taken to the dealer and was diagnosed with transmission power converter failure resulting in damages to the timing chain. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 135,000.”

“I was driving and going around 45mph when the wrench warning light came on and I lost the ability to accelerate. The car could only coast. I was able to coast to a parking lot. I turned off the car and restarted it. It seemed fine so I drove home. The same thing happened again a couple of days later. We checked the codes and it had a p2112 error code. We replaced the throttle body and it seems fine now. However this is the second time we have had to replace the throttle body. The same thing happened in 2018 with about 74000 miles on the car. We replaced the throttle body then also. From internet searches this seems to be a common problem. It is a big safety issue since the car loses the ability to accelerate unexpectedly. I was lucky I was able to coast out of the way each time without causing an accident.”
