- Park City, UT, USA

I was driving on a city street at about 30mph up a slight incline when the truck just seem to shut off. But it didn't die, the engine was still running but barely. It was running very rough, like miss firing on several cylinders. It would not accelerate, no change of engine sound or power, the throttle was totally unresponsive. It also felt as if the brakes were being applied slightly. A message came on the dash saying something about hill assist and another wrench message. I had no chose but to pull over in traffic before it quit. This was on or about July 18 then again today on July 26. This time I was one a city street down to one lane due to construction. I was barely able to make it to a turn off before it totally quit moving, with traffic backed up behind me. I shut off the engine to let the computer reboot and got a message that hill assist was now off. After a longer than normal crank time it started and ran ok. I called Stivers Ford to make an appointment and was told it was probably a fluke, and wait and see if it did it again. I now have an appointment for August 4 to have it checked. I went on Google after the first time and found many complaints about the same situations, but with no fixes. If this were to happen under the right circumstances it could be very serious. I'm a recently retired auto technician, and shop owner of 48 years. I understand the difficulty in finding intermittent failures. But after reading all the same symtoms in Ford pickups for years it seems there should be more done from the manufacturer to address this problem.

While driving on the freeway the truck completely lost throttle, note electrical stayed and engine idled roughly during this time. Had to emergently pull to the side of the freeway while the truck coasted nearly causing several accidents and people swerved around the truck. Since this initial incident this has happened approximately 15 times on various roads and in intersections. Dealership is saying that some of the electronic throttle bodies (TSB 16-0139) were defective which causes this issue.

Sounds like an exhaust leak near the turbo possibly at the manifold. It is very loud and can tell there is a significant loss of power.

While in motion and on the freeway there is power loss, shaking, engine sputtering and barely has enough power to get off the road, hill start assist disabled, decent control disabled, service wrench indicator, service advance trac. I powered off the truck, waiting 10 seconds and it starts and runs fine until it does it again.

When turning onto a road and starting to accelerate, the truck suddenly lost all power and the traction control, advance traction control, hill descent control, maintenance required light all came on and the truck went into limp mode. Luckily I was able to pull off the road and avoid being hit.

Truck fault code flashes and truck shuts down into safe mode. Three times it occurred while driving on freeway at 70 mph and the fourth time it happened in an a side road doing 35 mph. Every time the same thing happened, the truck shut down in safe mode showing fault codes. I would stop, it would idle very rough, I was not able to move it as it would not rev or let me increase RPM. I would have to shut off truck, turn it back on, it would reset and drive like normal. Took to courtesy Ford four times to diagnose and they could not find anything, I bought a code ready and the truck went into fault code and safety mode again, the code read P2112. Ford found tsb 16-0139 applied and replaced throttle body and charged me $496.95 for repair. 2015 Ford F150 with 58K miles.

My truck on multiple occasions was driving than immediately lost power and shut off after sending it to the dealership and them replacing the throttle body it was still doing this with a rattle noise. It got to the point where my truck at 52,000 miles did this exact thing again and blew white smoke and a hole now is in the oil pan.

My wife was driving vehicle and dash started flashing "hill start assist not available", "service advanced trac" and the wrench icon started displaying on console. Vehicle vibrated heavily slowed down in a "cripple" mode no matter how hard gas pedal was pressed. She pulled over, turned the ignition off and waited 5+ minutes before restarting. It re-started with engine light lit. In order to get it to dealer, she had to drive approximately 15 miles. Vehicle drove ok for a bit and then exhibited similar behavior 4 more times, including once going up the conejo grade between camarillo and newbury park where a big rig had to take evasive action to avoid hitting her when the Ford F150 suddenly and uncontrollably slowed down. Had the semi driving not been paying attention, he could have easily hit her. Ford dealer diagnosed as bad throttle body on 11/2/2020 same vehicle had exhibited brake loss due to faulty master cylinder (now a recall) in August of 2019.

Oil pan repair was unsuccessful. Began leaking 17,000 miles after initial warranty repair. Truck currently has 71,000 miles. 2nd issue is paint over windshield is peeling. It appears tape was not removed and primer did not adhere.

- Holland, MI, USA

Driving on highway 3 different times when acceleration stopped and check engine light came. Fortunately traffic was light when vehicle decelerated. I took vehicle to my mechanic and he had to replace throttle body. He googled problem and saw numerous types of same part vehicle. Called my Ford dealer and he confirmed that they had had to replace throttle body on certain models but Ford had not yet issued a recall notice. This is a very dangerous situation to lose throttle suddenly while driving. My mechanic replaced part, but Ford will not address as a recall issue

- Grand Junction, CO, USA

Engine has stalled and gone into 'limp' mode at highway speeds 4 times in the past few months. Have to pull over and turn truck off and then on to resume normal function. Got error codes about hill assist not working when turning the truck back on. Took to the Ford dealership and they could not replicate the issue. After researching online found numerous other people having exact same issue and it the resolution was replacing the throttle body. Called dealership and they said that might be it but didn't want to diagnosis it as that until they could replicate. Again voiced concern to them that if the vehicle goes into limp mode in the middle of the freeway that could be extremely dangerous. They said there were no recalls for my vehicle but appears multiple other models and years have had this recall already done.

The exhaust manifolds have warped causing studs to break leading to an exhaust leak. This is a very common problem with these engines. It produces a squealing noise under acceleration

Truck engine goes to rough idle while driving, have to shut engine off, restart. Never know when this might happen or at what speed. Local Ford dealer unable to find problem.has happened several times

- Alamogordo, NM, USA

While driving on crowded highway in boston area, truck lost engine power. Dash gave following warnings: See manual, service advancetrac, hill descent control fault, hill start assist not available. After emergently switching lanes with no engine power, I shut the truck down, paused, and restarted the engine. This happened ~20 times before I could get it fixed. The problem was a faulty throttle body. This was not covered by Ford even though I consider this a major safety hazard.

- Rowley, MA, USA

When accelerating, there is a loud chirping noise coming from the engine. The exhaust manifolds have warped. Very annoying sound and loss of power. Seems to be a common problem among other owners of the 3.5 eco boost. Very disappointing.

- Peoria, AZ, USA

While turning and accelerating onto a two lane highway while towing, there was a sudden loss of power and the instrument console displayed warning message, "service advancetrac." As I was accelerating to merge into traffic at the time of power loss, an unsafe condition was created as the semi-truck I pulled in front of now had to make evasive movements to avoid a collision with my now disabled truck and trailer in the roadway. Power came back on with restart of the truck, but only for a few minutes before the same loss of power and fault message. The code P2112 was pulled from the obd2 reader and it was determined the throttle body needed to be replaced. The problem was in fact fixed with replacement of the throttle body.
