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.

Was traveling down highway and vehicle started running rough, check engine light came on and exited highway when safe and vehicle quit running and wouldn't restart. It seems the timing chain broke and then damaged the engine. Dealer rep said they have seen a lot of these, but not recalls yet.

When pulling out into heavy traffic on a divided four lane road, the vehicle suddenly lost power and went into limp mode almost causing a serious accident. The check engine light came on and the code was later to be determined p2112 throttle actuator a control system stuck closed. After researching the issue it was apparent that the ford 3.5 ecoboost motor has quite a history of these type failures. Often driver safety is compromised as the vehicle suddenly and without warning will lose power just when you need it. The fix is to install a new throttle body with electronic actuator.

The day after we bought this vehicle used had 78,000 miles on it we were driving on a 4 lane road about 60mph when the check engine light came on and it put itself into neutral. The gas peddle would not engage. After we turn it off and on a couple times we were able to drive it again. This has happened at least three times since we have owned it. We bought it 4 months ago. On three other occasions the check engine light came on while returning home from a 3 hour drive on a highway going 60mph down a hill and it was under powered but still drivable. We had one turbo replaced however the light has come on again but the dealer couldn't fix it because the check engine light cleared and they can't find anything wrong with it. Last week we were driving in town thankfully under 30mph and the break peddle got hard and couldn't be pressed down. A light came on that said break failure we had to engage the emergency break to stop. We had it towed no lights were on when it got to the dealership they put 30 miles on it trying to recreate the problem and couldn't get it to do it again. This vehicle is very unsafe it's a matter of time before it either shuts down in the middle of a busy highway or the breaks won't work and crashes into something or someone. We have a vehicle now that we cannot drive and cannot fix and if we trade it in we will be out a lot of money and this unsafe vehicle will be put back on the lot.

On today's date, april 9, 2019 at approximately 4:20pm cdt, I was entering freeway accelerating to 40 MPH when power was lost and quickly decelerated to under 5mph. Engine still running, but it went into 'limp home' mode, no faster than 5mph. Was able to get to distress lane. Wrench symbol displayed on instrument cluster. Turned off engine and checked owners manual...symbol indicated power train trouble. Turned on started ok, and continued to freeway speed. About 1 mile later, lost power again, slowing to 'limp' mode. This time check engine and wrench lights came on and engine noticeably rough running. Turned off/on started ok, exited freeway and drove city streets home, about 3 miles. Check engine light never went off. Wrench light did go off after 2nd re-start. Manual recommends having ford dealer check it out. That's what I'll be doing tomorrow. This spontaneous loss of power has risk of causing a crash from other driver's as sudden decelerations without brake light warning is very dangerous.

While traveling in the passing (3rd) left lane on interstate highway with speeds of 65 to 70 MPH, the vehical totally loss power, motor still running but just at an uneven poor idle, still in gear, I attempted to accelerate, it did absolutely nothing yet the motor was still at the poor idle. On the dash comupter a wrench appeared with "see manual" along with a small check engine light above that. I was forced to get out of that dangerous situation with no power, coasting through 3 lanes with my wife waving out the passenger window to let my powerless car drift over. Once off the highway, the motor was still poorly idling, giving it gas did nothing, still just a rough idle. I shut the car off and restarted it and miraculously I once again had control of the accelerator. I was still 3 hours from home with all highway driving ahead of me, which I did doing 55mph in the slow lane & ready to turn off road. I bought a new vehicle as to not have problems, let alone the most dangerous episode of our lives. What really is unacceptable is that I just had a 70k mile checkup at a local ford dealer where I was told they reccomend changing my transfer case oil along with an oil change & tire rotation. I was given a clean bill of health for a road trip. I refuse to pay anything for a flaw in their design, especially being a dangerous safety issue.

Bad throttle body and gasket. Going 75 on a hwy in az and the wrench symbol pops up and the gas pedal no longer works! Luckily we were able to maneuver to the side of the hwy safely. Restarted it and it was like nothing happened no check engine light or anything. This happened about 12 times before we were able to connect a computer to it and get code p2112 throttle actuauter control system stuck closed. It didn't matter what speed we were going it would just all of sudden get stuck and the throttle would no longer work. This is a very dangerous issue that needs to be looked into!

Vehicle in motion on freeway at speed (70mph approx.) and suddenly lost power w/check engine light (orange wrench) coming on. Vehicle had no power/acceleration and seemed to only idle. Was able to coast to right shoulder. Shut engine off and waited for a few moments and turned back on, started up, and appeared to work normally, allowing us to continue on to destination.
