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.
While traveling on the highway at 70mph, my vehicle went limp, abruptly shook as I pulled over to the shoulder to avoid a collision. My indicator lights lit up like a christmas tree..."hill assist", "service advancetrak" " the "wrench" adn my check engine light remained on. Terrified, I got stopped, took the keys out and had it towed to the nearest dealer. Their diagnosis was that it was a throttle body failure. My service manager requested that I call Ford customer care. I did that immediately following the diagnosis with my repair being above $650. After a week of research, Ford came back and stated that they would not help me out at all. There are recalls for the specific problem including an extended warranty for 10 years and 150,000 miles, however I was told that I could not receive any help for the same part. I experienced a preknow condition with a part on my truck that was faulty with myself to blame. If I had known any of this I would have never purchased the vehicle.
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

I own a 2015 Ford F150. I was driving at 60 mph, the vehicle abruptly decelerated. The wrench and limp mode warning lights illuminated while the failure code P2112 occurred. I had to coast my vehicle on to the road shoulder and restart the engine. I had to stop and restart numerous times before I could make it home, off of a busy highway. When it stalled on me the next day, I had the vehicle towed to the dealer and paid for a diagnostic that located a failure code at the throttle body.
Auto start/stop causing wrench to come up. Seems like transmission has issue keeping proper fuel level to restart at red lights. Causes a hard start. Also driver door does not lock and unlock with the other 3 doors.
When accelerating, about 90% of the time the vehicle will get warnings for "hill descent control fault" and "advance track service". when this happens, the vehicle will not accelerate anymore and starts slowing down. This has happened to me twice getting onto the interstate in the past month but luckily no vehicles were coming up behind me. This is a huge safety issue though that Ford needs to recognize and fix. The dealership said they have no idea what is causing it but everyone online says that it's likely to be the steering rack. Recall the steering rack because this has apparently happened to a lot of people.
Code P1450- fuel tank is unable to bleed up fuel tank vacuum, and this has nothing to do with the fuel pressure sensor at the engine. It is a defective fuel tank pressure. Due to this defect, the check engine light stays on and a piece now needs to be removed.
Truck suddenly decelerated while traveling at 70mph. Pulled over, turned off truck and turned on again and accelerated onto the freeway. This happened 3 times on the freeway. Drove to Ford dealership in albuquerque for help. They evaluated and found the throttle body needed replacement. This same part was a safety recall item on our 2010 Ford escape.
Driving on an interstate 75 mph when the hillside assist light turned on the dash along with other warning lights and immediately lost all power to the engine requiring a pull off to shoulder. Shut off the engine and restarted with no problem, accelerated back to speed and within a few miles the light came on again and lost all power. This happened several more times while attempting to locate a local Ford dealer. While waiting at the dealer I searched online and found numerous others have experienced the same issue attributed to a defective throttle body (see attached screenshot). After bringing up the frequency of this issue with the dealer, I was told there is a tsb from Ford but no economic relief for the $675 bill since there was not a recall. The dealer stated there was not a recall because this is not a safety issue. I responded that driving 75mph on a busy urban interstate, losing all power, and being forced to find a shoulder immediately is a serious safety issue as one frantically tries to figure out what is happening and searching for a way out of traffic.
My 2015 F150 crew cab loses ability to accelerate. You will be going down road or pulling out and without any warning the check engine lights light up and the gas peddle will do nothing. It's very dangerous while in traffic. The truck only has 45,000 mi on it, done some research and it sounds like I'm not the only one having this problem.
Defective throttle body caused vehicle to lose power. Engine light on with messages service advanced trac/hill start not available. Truck has 44K miles
I purchased my 2015 F150 about a year ago. There is a tsb for a valve on the top of the gas tank. Tsb states emission related with warranty covered. Ford stating it was built in Canada so don't have to warranty in America. Vehicle cuts out after stopping and then accelerating. How can Ford sell a vehicle to be used in America with a known issue and not be liable? this is a safety concern. Tsb 15-0171 engine code P2450.. part number involved is same on Canada or american vehicles.
While in motion, at highway speeds on a highway and sometimes slower speeds on town streets too, my truck would suddenly start flashing multiple errors and the throttle would immediately be unresponsive. In 1 second I was dead in the water. The truck would immediately start slowing down due to lack of propulsion and the engine would have a very low rough idle. The throttle would not work at any speed. The only way to recover control of propulsion was to come to a complete stop right where the problem occurred (very dangerous), turn off the vehicle and then restart the vehicle. After restart the problem would completely disappear. Until it happened again. This problem appeared 3 times in 1 week, all while the vehicle was traveling uphill. I was lucky to not be in traffic at the time. I took the vehicle to the dealer and they reported the vehicle needed a new throttle body, and that this issue was common and that a recall was not in place. The repair cost is over $500.
Driving down highway when truck immediately lost power, began shaking violently, with no throttle/acceleration available. The dashboard was showing all the below errors. Hill descent control fault service advancetrac hill start assist not available
Truck goes into limp mode constant in middle of traffic. Severe safety hazard for all. Throws throttle body code. According to dealer its not covered in yhe recall or whatever Ford called it but its gonna get us killed.
Transmission downshifts violently for no reason. At around 20-30 mph and light throttle it feels like you hit a concrete post when this happens. Shakes the whole truck violently
While driving on a two-lane road, my engine went to "limp" mode, no power, rough idle and the dash warning lights (wrench, check service manual etc.) all lit up. No power and costed to the side of the road. Shut off, then vehicle started normally before doing it a 2nd time. Had towed to the Ford dealer (ray schultens, the dalles Oregon). Diagnosed as faulty throttle body assembly (Ford tsb 16-0139) not covered under powertrain warranty but this condition makes the vehicle inherently unsafe with no ability to control engine power.
Truck went into limp mode after stopping for a red light. This happened twice one day. Dealership said they replaced the throttle body assembly. When in limp it took forever to get through the intersection, long enough that the light changed back to red.
