What owners say about the engine
Verbatim from NHTSA complaints, newest first
“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.”
“My 2015 Ford Expedition needs to added to the recall 22S56. I just paid $1,200 to have that part fixed cause it burnt up. Replaced the front blower motor assembly. My husband burnt his hand on the wire exposed under the dash then the mechanic said the blower motor has burnt up the components around it. The fan, motor, control, and wire assembly all was burnt up. Ford needs to be made to include my vehicle in their recall as that vehicle year, model, plant made in and date made all match.”
“The contact owns a 2015 Ford Expedition. The contact stated while attempting to drive from being stationary, the vehicle hesitated and stalled. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine needed to be replaced or rebuilt. The contact stated that the timing chain had been replaced on two separate occasions. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The approximate failure mileage was 132,000.”
“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.”
“Driving 45mph the stuttered quickly and the wrench symbol appeared on the dashboard. I had to put the car in Neutral and tranisted to the shoulder of the road, stopped and turned the vehicle off. This is not the first time this has happened. It happened to my wife and my daughter at separate times also.”
“The mechanic assessing my vehicle stated that the vehicle has a coolant leak which cause the vehicle to run hot and ruin the head gaskets and requiring a new engine to repair at a significantly high cost. I explained to him that a check engine light only came on a day before and he stated that he has seen this a common problem in Ford Truck (F150 and expedition engines) with the 3.5 L turbo. The coolant sensor doesn’t pick up the leak because the coolant evaporates before the sensor can detect and only has cooler air passing over it thus not notifying the driver of the vehicle. I have maintained this vehicle properly since purchased in 2018. The risk was the engine could’ve overheated potentially causing fire or harm at high speeds.”
