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.
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.
