6/25/24 I put my 2015 F150 in reverse and gave it just a little acceleration and it immediately accelerated fast crossing the street and hitting a utility pole totaling my truck. I did some research on a Ford forum an saw where othe people had had rapid unexplained acceration.one person said it was because of a faulty accelerato pedal positon also known as app. My safety and anyone walking or driving by my house were greatly put at risk. The problem has not been reproduced or confirmed by anyone. There were no warning lamps or messages. This nightmare came out of nowhere.

I am driving back to Florida on [XXX] and my engine light comes on and the wrench symbol on my dash, as I am going about 70 mph and accelerate suddenly my truck going from gear/speed 6 down to 5. I take my foot off the accelerate and it goes back to speed /gear 6. If i stay at one speed and do not accelerate its ok, the minute I accelerate it changes speed. I took it into the Ford Dealer in Daytona Beach, and they are fixing the problem, but I don't have all the details. I am wondering if this is related to your recall to the 2014 F-150 where the problem is exactly like mine. I have not gotten the truck back, only that it is costing around $2400.

The 2015 F150 shifted itself from drive at 60mph to 1st gear. I as leading traffic when this occurred. The rest of traffic went around me as, I went to shoulder of rd. The F150 shuttered and was unable to be steered safely off the road. Warning lights flashed but as a driver I was unable to watch as traffic behind me was more important then watching F150. As a Simi was also close to me. This was a very scary event! As my husband was with me and is [XXX] he doesn't drive. Smoke came from under the vehicle. I see this is a common accurate with the F series of 2014. I would suggest checking the 2015. We have since had it fixed and it now drives better. I noticed a marked difference, from when I purchased it a few mos. Earlier. Seriously it could have been a wreck. Strong driving instinct is what saved us this time.

In 2022, while behind the wheel of my 2015 F150, I would be driving down the highway (70+ mph) and the transmission would suddenly downshift to 1st gear, then jump to 3rd, and then back down to first gear, all over the place. This happened on several occasions. It was erratic, I experienced sudden changes in speed, sudden and frightening revving of the engine (especially on the highway) and on several occasions I had to make sudden changes to my driving to ensure my safety as well as the safety of others on the road. After I was able to pull over and turn my truck off, the truck would either not turn back on or take a while to be able to turn on. I had no warning that the transmission was about to shift gears and only noticed a check engine light after the incident had occurred. After taking my truck to a transmission shop and they did not find an issue with the transmission (it worked correctly while they test drove it), I took it to a Ford Dealership where I was told there was a fault with the CAM Shaft sensors. After a $3,000 repair to fix the issue, I recently found Ford has Recalled 2014 F-150s for issues that sound identical to what I was experiencing in my 2015 F-150.

During normal highway driving, the vehicle abruptly went into "limp mode" with a complete loss of throttle control. The engine remained running, but I was unable to increase the speed of the vehicle. Once stopped, the vehicle showed several alerts on the dashboard: "Service Advancetrac, " "Hill Assist Not Available, " and "See Owners Manual." I was able to scan for fault codes and returned DTC P2112: Throttle Actuator Control System Stuck Closed. Upon further research, there is a Ford Technical Service Bulletin # TSB 16-0193 which states the vehicle may exhibit an intermittent loss of power and/or an illuminated powertrain malfunction (wrench) lamp with diagnostic trouble codes (DTCs) P2111, P2112 and/or P2119 stored in powertrain control module (PCM) memory." After restarting the vehicle, it returned to normal operation with the dashboard errors remaining. A Ford dealer is scheduled to look at the vehicle. I have been told they expect to diagnose and replace a faulty Electronic Throttle Body. Losing complete throttle control while driving on a busy highway is dangerous for many obvious reasons.

No lights previous to incident. Sudden engine & speed malfunction. Yes, it happened multiple times heading to the ford dealer-2 mi away. We kept the hazard lights on. Sudden loss of power while driving, engine goes into limp mode, down hill assist light and altrack light comes on. Truck restarts but again limps unexpectedly. Took it to dealer -it was the throttle body that had been replaced 3 1/2 years ago by dealer.

accelator stuck to the floor a couple of times when gassing it to pass other cars on the roads. The pedal would actually will stay pressed down even when my foot is off the pedal, it will speed the truck up even when pressing down hard on the brakes. when i got it to stop and cut the truck off while in park and turning the key the rpms were going absouletely nuts. looking to see if this is a common occurance. thanks in advance!

While driving at posted speeds on open highway and in congested work zones, this F-150 experienced an Electronic Throttle Body failure 5 times between Rochester Hills, MI and Granger, IN on 9/13/2022. It happened again on 9/14/2022 in city two way traffic with no shoulder. In each incident, the vehicle went into limp mode with rough idle and had to be completely stopped, turned off and restarted in high traffic, hazardous stopping locations. This happened once before in the mountains in Utah, in a construction zone back on 5/02/2021. At that time, the check engine light did not stay on and Ford was unable to find a code. It did not happen again until 9/13/2022. These incidents put me and my family in danger with each episode. Ford is fully aware of this issue, has in the past and should notify owners of the potential issue and continue to make repairs available as a recall or extended warranty service issue.

I was driving down the road like I always do, the cruise control just shut off. I tried to re-engage it and it would not respond, about 15 minutes later I engaged the cruise control successfully. This has happened numerous times over the last three weeks and now in order to engage the cruise control, I lift with my fingertips, the top left and the bottom left of the button and then it will engage. One occasion, the dash lights in trip 1 mode flashed. Then the control began working again.

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.

I was driving my 2015 F-150 on a city street at 35 mph when suddenly my truck lost all acceleration power and began to shake violently. The engine continued to shake and sputter as I brought the vehicle to a stop. The service engine light came on along with two codes to 'service advancetrac' and 'hill decent control fault'. I turned the vehicle off, then restarted. It seemed to take longer to crank, but it started and I proceeded down the road. Each time the vehicle would reach 35 mph the same sequence would occur with the vehicle shaking violently and losing all acceleration power along with the service codes flashing. I researched my problem and read story after story on the internet of others who owned 2015 F-150's with the same exact issue happening. I even found a recall Ford issued: 16B32 for a defective throttle body, but was told at my local Ford service center that although the identical thing happened with others, my truck was not listed under that recall. I had to pay $500 out of pocket for them to replace my defective throttle body plus labor costs. This seems to be a common issue with these 2015 trucks. I would like to see something done to include more trucks like mine with similar issues into that recall. I should not have been responsible for paying almost $500 to get this problem fixed. I'm just glad I wasn't on the highway or pulling my camper trailer. It's just a matter of time before someone is killed or badly injured because of this problem! please do something about it before this happens!

On adaptive cruise control, since new, the vehicle brakes are applied when passing an 18 wheel truck/trailer (sometimes) causing a rapid 15-20 mph hard braking decrease in speed jolting and scaring the occupants of the Ford. Nearly rear ended several times. Have contacted Ford but they did not care nor were they concerned that this is a safety issue. Very dangerous going from 65 to 45 while passing another vehicle and cars are behind me. This is a random occurrence making it even more scary. This has happened too many times to count since 2015 and I am afraid to use the adaptive cruise control for fear of being hit from behind on the highway.

While driving on highway at 55 mph (6th gear), vehicle suddenly downshifted to 1st gear. The engine's rpms revved as the vehicle began to decelerate hard, resulting in the passengers experiencing a sudden jerk of their neck and body. The accelerator pedal had no response. After approximately 5 seconds I regained response from the accelerator and the vehicle began to upshift. A few moments later, the whole experience repeated with the vehicle downshifting to 1st. This repeated a third time. The incident caused several near-misses as we lost power at highway speed and began a rapid deceleration without notice.
