I purchased a Ford F 150 with 11 miles on it in November 2015. It now has 14,000 miles on it. It has broken down three times for the same issue. It now has it's forth (4) throttle body in it. This is a safety issue. The vehicle goes into a crawl mode. It has occurred while driving on highways. Ford needs to replace this vehicle. It's a lemon.

I have a 2015 F150 king ranch with the 3.5L ecoboost. It has 41,000 miles and never had an issue until yesterday morning and today around lunch. This was from yesterday 10/23/17: Hill descent control fault service advancetrac hill start assist not available I was pulling out onto a highway and the truck began shaking violently, moving very slow with no acceleration, power steering was lost, and the dashboard was showing all the above errors. Luckily there were no vehicles coming when I entered the highway and there was a place to safely pull off the highway. The truck continues to idle rough and shake violently. And today 10/24/17: I was driving down the interstate at 70 mph when the truck did the same thing as yesterday morning. I was able to pull off the side of the highway and shut off the motor. Once I restarted the engine, I was able to get it to the local Ford dealership. They say they have no idea why it would be doing this and have not heard anything from Ford or seen this in other F150's they have serviced. Update: The dealership claims the fix is in a faulty electronic throttle body and they replaced it at a whopping price of $770. A simple google search shows Ford has issues with etb's across vehicles of all classes and knows about it. In fact, some consumers seem to be involved in lawsuits against Ford because of their unwillingness to issue a recall before someone is fatally injured. These were scary, scary situations with my vehicle and thank god my wife and kids were not with me. There is obviously an issue and Ford needs to correct it at their expense.

Vehicle was on I88 westbound in 4:30 rush hour traffic near naperville, il when the dash lit up, speed dropped dramatically and the gas pedal went dead-no response. Engine speed reduced to a rough idle. Had to somehow get to the shoulder to restart engine to get rid of the error. Was fortunate the problem did not recur until next day on side roads. Brought vehicle to willowbrook Ford dealer who replaced the throttle body on 8/17/2017. Why a service advance trac error message occurs for a fuel problem boggles my mind.

Truck intermittently and without warning lost power and went into "limp mode". several error messages appeared on the dashboard including "hill start assist not available", "hill descent control fault", "service advance trac" and "see manual"..the wrench and engine lights also appeared. There would be no throttle response and the engine appeared to be running on 4 out of 6 cylinders. Took the truck to have the codes scanned and the following two codes appeared: P2111 throttle actuator control system - stuck open and P2112 throttle actuator control system - stuck closed. Took the truck to a Ford dealer and was told my VIN did not have a throttle body recall but in their opinion, it was a defective throttle body not covered under warranty. I replaced the throttle body with a bbk-1822 throttle body assembly myself.

Electronic throttle body assembly (etb) failed. Vehicle has 8206 miles on it. Bought brand new. While driving on a fairly untraveled road the engine power was cut and I had to coast to a safe location. The accelerator only allowed for a speed under ~4 mph which I needed to get on the side street. This happened again as I was exciting my driveway which is on a dangerous street due to curves (luckily there were no cars coming from either direction). This has been an issue with Ford and Mercury vehicles since at least 2010 based on my research. Ntsb has failed to have Ford recall their vehicles to replace this system. This issue results in (my experience) complete loss of power to the engine. It may also lead to full power to the engine. If either occurs it has a potential to result in injury or death (sudden slowdown in high speed traffic or sudden increase in velocity in an area with pedestrians). I do not understand why the ntsb has not made Ford conduct a recall considering the potential danger this may cause. Ntsb has known about this issue but has failed to force Ford to correct it. The issue appears to have started with the Fusion/escape (plus two Mercury vehicles) and is now happening in F-150 trucks. I do not know if it is happening in other Ford/Mercury lines. Ford has failed to adequately prepare for their "we'll fix it as it happens" (so much for customer care) and I am now out of a vehicle for at least two weeks. Very disappointed in this company as I felt it was worth purchasing an american truck and that Ford was the number one world wide.

"check brake or check brake controller" appears on dash. Has occured twice in first 8,000 miles. Dealers clear code the brakes seem to be fine. Now " check hill decent" has appeared and truck will not accelerate more than 2-3 mph. This has occured twice in first 8,000 miles on city streets in motion or when starting from a stop light.

While driving on freeway at approximately 55 mph vehicle suddenly lost power. Several emergency lights sequenced on. I realized that engine was still running at idle and that vehicle kept moving at approximately 15 mph. Got off road and shut down vehicle and restarted it. Same problem existed. At idol speed vehicle would slowly move. Pressing accelerator pedal did nothing. Ford representative indicates that this is a widespread problem. No info yet on redesigned replacement part. I was told by dealership that the problem is the "throttle body motor assembly". I received no information from Ford prior to this incident and do not see a recall.

Got on I-95 South driving 65 mph smelling gasoline opened closed windows turned of and on A/C still smelling gasoline got off the highway at commerical blvd exit. Got out of vehicle to see gasoline pouring down from drivers side rear in front of right rear tire walked about 200 feet dialed 911 contacted police and fire.. fire truck spread chemicals on floor now truck is in Ford to repair the gas leak.. when I have the repair bill I will know the exact part replaced. If the truck would have caught fire I would be dead there is no way to exit a burning vehicle at 65 mph.

After morning startup, vehicle stumbled, hesitated on acceleration into traffic. Vehicle stalled after approximately driving 1 mile. Would re-start, only idle, then stall when put into drive and attempted to re-enter traffic. I had towed to closest Ford dealership for warranty repairs. My vehicle was returned over two weeks later. The service invoice outlined that the low pressure fuel pump was found bad, shorted and connecting plug to harness melted. They replaced fuel pump and repaired harness plug. Vehicle was not fixed. Over the two week period the vehicle was at the dealership, the fuel pump driver, body control module, and last the engine control module was replaced to repair the problem. My major concern is the melted fuel pump plug. I would think there would be adequate fusible link protection to keep this kind of problem from happening especially when affecting an in tank fuel pump. This might lead to fuel fires and also accidents due to loss of power from the engine. I was fortunate to be able to safely get my vehicle on the road shoulder, and then onto a side street with minimal traffic. Another issue is that one device failure creating failures in multiple vehicle control systems that would cost the consumer thousands of dollars out of warranty to repair. I was told that a Ford field engineer was sent to assist the dealership, after his visit, the ECM was replaced which made the vehicle functional again. Adequate overcurrent protection on the fuel pump should have prevented damaging the other critical parts. Ford has put a lot of these vehicles on the road with the fuel efficiency new engineering as a major marketing tool. I fear the vehicle may have been rushed to production with inherent flaws that could be a danger to owners and the public.
