On 1/25/16, in the rain, at 6 am, I pulled out from a side street near my residence on to a major road and was increasing speed. I traveled about 150 yards and was up to about 40 mph. My truck suddenly decelerated to about 5 mph very quickly causing my car to skid in the rain. There was no accident since traffic was light at the time, so I pulled into the median and put the truck in park to see what was happening and I could not discover anything wrong. I then put the truck in gear and tried to accelerate again but the car would speed up to about 15 mph and then decelerate very quickly, almost giving it a bucking motion. After a few seconds the truck seemed to want to die, it would move and then seem to want to stop and die, and then repeat the process. I was able to get to the side of the road and park in a parking lot. I had my truck towed to the dealer and the dealer looked at it but said they couldn't find anything and had never heard of that happening to anyone before. I looked on the NHTSA site and found that many people had had this occur in this model. The work order received from the dealer did not indicate that anything was adjusted or replaced. To date it has not reoccurred.

Driving about 50 mph lost engine speed suddenly to about 10 mph. Have been told by 2 others that this also happened to them. Same truck model. Root cause given was throttle body cable. Accelarator box. Having ours towed to dealer ship today. Under 10,000 miles on vehicle.

I noticed a faint smell of gas while driving the vehicle and after a few miles a car next to me at a stoplight asked me to roll down my window. They told me my truck was leaking gas all over the road so I immediately pulled over and called for help. It was towed to a dealership where they told me a fuel line fitting was loose which caused the leak. My frustration was this was a new vehicle with only 1500 miles. The leak was severe enough to drain a full tank of gas prior to being repaired.

2016 Ford F-150 2.7L ecoboost model with only 3,928 miles. This is the third time engine has cut off on me while driving/accelerating! was taking a left turn from side road onto main road. While accelerating in the turn, engine started stuttering a few times (rpms would dip) and then it stalled out. Luckily I was able to complete my left hand turn without getting hitting by oncoming traffic and was able to pull over immediately. This time around the engine would not restart. Had to call Ford's roadside assistance to get towed to nearest dealership. The last two instances the dealer could not pull a code or diagnose what was wrong so nothing was done. This time the dealership has a dead truck on arrival so they can't tell me that there is nothing wrong with it (service and diagnostics has yet to be completed at the time of this writing). I have been in touch with Ford regional rep regarding my cases and I am told they cannot do anything until the dealer can diagnose what the root cause is. Obviously something is wrong. There are dozens of other complaints of engine stalling while driving.

Second time engine stalled while driving in less than 2 weeks!!! 2016 Ford F-150 XLT 2.7L eco-boost model. This is the second time the engine has stalled and shut off during driving! not even 3,600 miles on it yet. Typical stop and go traffic during rush hour. Went to accelerate after rolling along with traffic (<10 mph) and nothing happens. Tachometer stays at around 500 RPM and does not go anywhere. Since this was the second time this has happen within the last 2 weeks so I wasn't too surprised this time around. I put it in neutral and shut off ignition and try cranking it. Rpms would barely stutter around 400-500 RPM and would not stay on. Tried a few more attempts while still rolling in neutral. I had to brake to a stop, put it in park, and had attempted to crank it several more times until it finally started up and was idling correctly around 800-900 RPM. This is definitely a safety issue and should be investigated immediately. Dealer says oem has known issue with throttle body causing Ford vehicles to stall while driving. Unfortunately, dealer says my VIN is not part of vehicle models affected by this issue. Obviously it is happening to the 2016 F150S. Both of my incidents did not throw a code so there seems to be nothing dealer can do to fix the problem for the moment. I do not want to keep driving this vehicle with this defective part and unsafe condition, especially with my infant son in the rear cab.

Ford throttle body issue - vehicle has less than 9000 miles. While traveling on highway (65-70mph) in a remote area, the vehicle suddenly loss acceleration and begun to shudder. No response when pressing gas pedal. We coasted to the roadside and attempted to restart the car. Vehicle dash warnings for descent assistance and collision avoidance appeared. Third attempt to restart vehicle worked. The issue occurred on 4 other occasions including stalling in a busy intersection shortly after accelerating from a stop. Each time restarting the car results in shuddering and error messages on the dash. Dealership says its a known issue and parts will take up to 3 weeks plus repair time. Manufacturer offered only to check on parts and update us 4 days later. They did not offered loan vehicle. Internet research points to defective throttle body for similar vehicles. Vehicle also has a defective sensor for tailgate ajar that has been unresolved in two attempts to repair. Vehicle is unsafe to drive.
