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.

While trying to pass a dump truck on the interstate with adaptive cruise on, vehicle slammed on the brakes, and causing the vehicle behind me to slam on theirs to avoid hitting me.. I noticed that there had been a recall for this before in 2015, but I never received any notice of this.. it is a very serious road hazard!!

Vehicle accelerated of its own Accord driving straight on highway. Took to dealer (village Ford, ocala, fl), they ran black box and did warranty work. A few weeks later, vehicle accelerated again of its own Accord while attempting to slow down to make a left turn. Vehicle collided into a tree.

Driving down the road today being mindful of the speed limit since I just got a speeding ticket two weeks prior. I looked at the speedometer and it read 62. I know the difference I speed variation just from driver feeling and experience. Well I applied the brakes and the speedometer did not move. When I reached my destination I put the car in park and noticed my speedometer was frozen at 40 mph. So now according to the trucks brain 40 mph = 0 mph

  • 77,000 miles
While accelerating the vehicle to get to 55 mph the engine suddenly lost throttle response and began to run rough. Simultaneously the dash flashed that uphill assist was deactivated and flashed the maintenance wrench. Upon pulling the vehicle over and shutting it off and restarting it the vehicle ran normally. The frequency of this increased from once every couple of weeks to now up to 5 times in 10 miles. When it causes an obd code it is P2112. It occurs most frequently while accelerating to highway speeds but has also occurred while at highway speed and accelerating to village speeds of 30 mph. It has even occurred once while using cruise control as the vehicle was climbing a hill. At this time it is unknown what is causing the fault. An attempt has been made to clean the throttle body and the problem persists. A new throttle body is on order but has to be installed yet to see if it corrects the issue.

I picked up my 2015 Ford F150 on Thursday of last week because the master cylinder was leaking and caused my wife to lose her brakes while driving on the highway. I drove my truck to our family reunion about an hour and half away on Saturday which was 2 days after I had picked my truck up and the cruise control would not shut off by taping the brake. My wife and I were traveling on a highway and I was in the slow lane with the cruise set at 72mph. I was approaching the vehicle in front of me, so I looked in my left mirror and noticed a car coming up beside me. I was unable to pass, so I touched the brakes to disengage the cruise control and I looked back in my mirror again to see if the car beside me was going to pass me soon. My wife then said what are you doing? I told her I am going to pass this car in front of us after the car beside me passed us. She then said well you better slow down because you are about to hit the car in front of us. Here my cruise control never disengaged so I touched the brakes 2 more times and nothing happened. I finally had to slam on the breaks and it finally disengaged. I had almost rear ended the car in front of us. I then got into the fast lane and placed the cruise control on again and found out that I was unable to disengage the cruise control by tapping the brakes like you should. I had to push the brake pedal 2/3 of the way to the floor which at this point you are stopping on the highway. This is the third safety issue in less than 1 year that almost caused an accident and that it has been towed to Ford. My truck is currently at Ford. Dec 2018 throttle body went bad and shut off with my wife driving my truck, Sept 2019 master cylinder went bad and caused my wife to lose the brakes while on the highway, and Sept 2019 cruise control not working properly almost causing an accident.

Alert - alert I wrote before about trouble with the 2015 Ford F150 stalling out while driving. I mechanic took ours out for a test drive and it did the same for him on the interstate. Please have someone address this issue before someone dies or has severe injuries due to vehicle stalling at random and for no apparent reason. I am just glad he wasn't passing on a 2 lane road or pulling a trailer. I can't believe Ford has not addressed this - it's on you tube. This is the opposite of speeding up - imagine you have your kids, etc in the truck, in the middle of a major interstate with cars all around you and you stall out completely. Please, please do something about this. It only happens in motion.

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.

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.

When I started the car, put it in drive, the truck went to full throttle on its own without touching the accelerator, and it took off at an excessive speed. I tried braking, but it just threw me into a power slide. So, once I was finally able to straighten the car without flipping it, I could turn loose with one hand and kill the engine. That's the only way it would stop. I was forced to go through the yard with things flying out of the bed of the truck ruining a 5 gallon can of paint we had mixed to paint the inside of the house. I am a professional truck driver, and this scared the death out of me.

My 2015 F150 ecoboost has 79,156 miles on it. Over the past 3 days the truck has repeatedly lost power while driving in traffic on the highway. The RPM will drop down to 500 RPM, rough idle, no acceleration at all, hill assist light wrench light check engine light passenger air bag light and see owners manual pop up on the instrument panel. Took my truck into Ford today and they replaced the throttle body under my extende warranty not their emissions warranty as stated in their owners manual of 8 years or 80,000 miles. Called Ford and they don't know about an emissions warranty in their owners manual. Looked online and youtube to discover this problem is not just me and frequent with others. This can really cause a horrible accident. Luckily I'm a cdl driver and was able to safely get over on the shoulder this time. I'm not confident replacing the throttle body was a fix as it is a bandage to happen again at any point in time. This truck now is compromised and I wouldn't want any of my family using it or depending on it.

2015 F-150 3.5L ecoboost driving on highway at speeds 60-75mph went to "limp mode" losing all acceleration with warnings "service advance trac" "hill descent control fault" and "hill start assist not available" along with the service wrench light. Resulted having to pull over on interstate 10 with busy traffic, also while in the middle of a traffic light turning left. This has happened 6 times. Ford dealer has diagnosed this as a throttle body issue and will be replaced at my cost

My Ford truck has had issues with lurching while at a stop, hard downshifts. And as of Friday night, going from 75 mph on the interstate to a dead standstill as though my transmission locked up. Almost created a pileup on interstate 70. Then would have RPM btwn 5 to 8 going 20 mph. 2015 model V8 with ecoboost. My year was not part of the recall announced but the symptoms described in that recall fit mine exactly. I am going to file a complaint with Ford as well.

P2112 obd error code - throttle body closed - while driving at any speed - in this case on the highway - engine would drop to limp mode, various errors display on dash. Have to pull over, shut off engine, then restart it to reset. Know issue with numerous Ford F150 ecoboost and mustang gas engines. This is very dangerous especially if I cannot pull off to the side to shut off the motor. Very high possibility of getting rear-ended by other fast moving cars potentially causing harm to driver and others.
