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.

2015 F150 - without warning - driving at 30 mph on a road and the engine shut down. Hill assist came on along with skid anti-sway motion and a wrench appeared in the indicator light. Truck would not move. I turned off the engine and started it back up and it ran until I reached 45 mph on a 4 lane main road and the engine shut down and I had to coast to the side and restart again. This is a very hazardous situation especially if I had been on an interstate with multiple lanes. I am surprised Ford has not issued a recall on this matter. It happened suddenly and without warning. Please look into this asap - I have seen postings where other people are having the same problem.

While driving on a mountain highway (~7000 ft elevation) in Colorado, my 2015 Ford F150 suddenly lost speed and vibrated wildly before stalling completely in the middle of the highway. While stopped, the truck continued to vibrate. Various warning lights illuminated (check engine, hill assist not working, check manual, etc.) and I had to turn off my truck and re-start to pull off the road. The problem happened 3 more times within 2 hrs but this time I was able to track additional metrics (but I moved over to a secondary road with little to no traffic) to relocate to a safe location. The 3 additional stall events were triggered between rpms of 1000 and 2000. As I approached 2000 rpms and/or climbed a slight hill, I could feel the truck begin to loss throttle and if I did not back off on the gas peddle, the truck would stall. I am having my truck towed to a Ford dealership but I am at 36,747 miles and just beyond my warranty. I consider this a very danger system failure for a low mileage vehicle.

Engine goes into limp mode on the road, street or highway with no warning. Engine shuts down. Dealer installed new throttle body for the third time!

- Dripping Springs, TX, USA

Randomly the hill start assist control error would come up. Additionally, service advance trac error would come up and the truck would go into some sort of limp mode with no acceleration allowed. Finally, the truck started running really rough. All these things would happen while I was in motion and or turning. I have been broken down on the side of the highway 4 separate times now. Everything is really random and can't be replicated. It's done this about 10 times now and the dealer has no idea how to fix it. My truck has been there for over a week with no remedy.

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.

- Lafollette, TN, USA

Driving on highway at 60 mph, climbing slight incline, multiple warnings regarding hill assist, ABS, traction control, etc. Populate on dash. Truck goes in to "limp" mode, steering becomes stiff and speed reduces until it comes to a rough idle.

- Ashland, KY, USA

This is the second time the engine just seized on me while driving in motion, on the interstate, at a high rate of speed and I would have to change the gear to keep it from stalling! this is a serious safety issue. I am taking it in for service at autonation Ford in sanford fl, again today!

My 2015 3.5 F150 has been experiencing sudden downshifting at random times. Typically, it happens once every hundred miles or so and takes the gears from 5 or 6 all the way to 1 or 2 gear at highway speeds. It is scary especially since we are supposed to be pulling a camper across the West for a few months. First the dealership said that it was a throttle body issue so I replaced that. Now they are saying that it is spark plugs. Apparently, four out of six misfire at the same time randomly which they said would cause the downshift. However, I just had them replaced with new boots three months ago. The issue did start after a dealer transflush but I do not know if it is a coincidence or not.

The contact owns a 2015 Ford F-150. While driving 70 mph, the vehicle's throttle completely failed and several unknown warning indicators illuminated. The contact was able to coast the vehicle to the side of the road and restart the vehicle. The vehicle was taken to holmes tuttle Ford Lincoln (660 w auto mall dr, tucson, AZ 85705, (866) 930-6255) where it was diagnosed that the throttle body needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 79,500.

My 2015 F150 with 100,700 miles on it completely stalled on me while pulling into traffic. I lost all control and had no throttle response and the truck went into idle mode and would not do anything until I put in park and then turned the truck off and then restarted the truck. Ran my codes and noticed that it showed a P2112 code which was a fault with the throttle body response. This caused my truck to completely lose all function in the middle of a busy intersection with cross traffic. Luckily there were people turning to prevent an 18 wheeler from coming towards me and the speed limit of 55 mph. This is totally unacceptable for this to just shutdown like this and cause serious danger for myself and those driving around me. After reading online it seems that this is a common problem with these throttle body assembly's. this is not ok!!!! I replaced the throttle body myself without paying $800 at the Ford dealership. This has to be addressed for safety reasons.

While driving on the highway through town at 35mph lost all acceleration, message on the screen said see manual, service advancetrac, hill descent control fault and collision warning not available. Stopped in the middle of traffic, could not get off the road. Shut vehicle of then on again and drove for half a mile before it did it again. This time I was able to move from traffic and park safely vehicle will idle but not move. This happened ten times in two days in varying traffic conditions

- Eagle, CO, USA

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.

- Mosinee, WI, USA

Loss of engine power while driving, code hill assist not available, ,sevice advance trac and service engine light comes

- Elkhart, IN, USA

When driving down the road an error will randomly pop up stating 'see manual' then another one pops up stating 'hill descent control fault.' The truck then loses all power. You have to carefully drive off the road (with no power) and stop and then restart. Sometimes it will start and be fine, other times the error will appear again. Very unsafe if you lose power driving 80mph down the interstate.

- Hadley, PA, USA

Corroded body control module and wiring. Ford technicians unable to diagnose cause. Caused vehicle to go into limp mode while driving in an unsafe manner.

The contact owns a 2015 Ford F-150. While driving 60 mph, the vehicle stalled and the engine would not restart. The contact attempted to restart the engine; however, the vehicle began shaking and would not stop. Also, 'hill descent control fault' and 'service advancetrac" appeared on the instrument panel. The vehicle was towed to paducah Ford (3476 park ave, paducah, ky 42001, (270) 444-0011) where it was diagnosed that a new throttle body needed to be installed. The contact planned to have the vehicle repaired this week. The manufacturer was made aware of the failure and stated that the vehicle was not included in a recall. The failure mileage was 104,000.

- Bradey, TX, USA

Floored throttle to pass slower traffic on highway and engine did not return to normal RPM. Instead, the engine continued run at 4,000 RPM until I was able to bring vehicle to a stop and use key to turn off engine. Upon restarting all was normal.
