While accelerating onto the freeway from the on-ramp, all throttle control went away and the truck started decelerating along with warning lamps turning on the driver display panel. Steep hill descent fault, sensortrac fault. Had to pull coast over to the shoulder under rough idle and turn off the vehicle ignition. After cycling the ignition, the throttle control came back. This has happened at least 5 times now during the last week or so. After a google search online, I have found that this seems to be a very common occurance with Ford F-150's and seems to be related to the electronic throttle body controller. Ford has tsb 16-0139 documenting the issue

- Castro Valley, CA, USA

When using the adaptive cruise control (acc) and passing alongside a semi-truck in the left lane, the system mistakenly detects something that causes it to slam on the brakes and set off the crash warning system. A couple of seconds later it accelerated back to your original speed setting. Brought the truck to 2 Ford dealerships and 1 just set the sensitivity level to low and the other one did an update to the control module. Neither of these has worked and the truck continues to do this. I called the dealership and they said they have no other direction from Ford on how to resolve this issue. This has happened over a dozen times since I have owned the vehicle and it is just a matter of time before this will cause a major accident especially when I have vehicles following behind me alongside a semi.

- Anoka, MN, USA

I received a recall notice, 15S29, to reprogram my F-150's control system to correct an adaptive cruse control issue. I had this recall work performed by my Ford dealership in March, 2017. I was on a road trip this week (4-4-2017) and was traveling on the I-35 interstate at 75 mph passing a semi. About half way passed the semi the brakes were suddenly applied and the warning flasher (on the windshield) activated. I thought this was fixed!! thankfully the vehicle behind me was able to brake to avoid a rear collision. Is there still an issue with this" if so when will it be fixed"

- Leander, TX, USA

This is the fourth time I'm reporting this. Although my vehicle should have qualified for Ford's recall 15S29, I was never notified. But I have mentioned it to my dealer 3 or 4 different times. They always tell me there's nothing they can do. So here's the issue. When driving on the highway, my truck thinks I'm going to hit something and the alert lights and sounds come on (and once since I had adaptive cruise control on, it applied the brakes at 70 mph). This is not safe. The dealerships say there is nothing they can do to fix my truck, yet the issue keeps happening.

- Olathe, KS, USA

This is a work truck driven by several people. Vehicle will sometimes keep accelerating without pedal being depressed. Also will not disengage cruise control. Have to shift to neutral and wait a few seconds for engine RPM to lower. Check engine light doesn't come on. Has been to Ford dealer on 12/05/16 and 12/20/16-1/10/17. They said they couldn't replicate problem.

- Sterlington, LA, USA

Adaptive cruise control periodically detects a truck in the right as being in front of me. It activates the brakes to avoid a assumed collision even though the lane is clear ahead. The brakes have, on occasion, be applied automatically in a very strong manner. I am afraid that this condition can lead to someone rear ending my truck. The dealer could not confirm any issues, however it has happened own occasion since new.

- Grosse Pointe Woods, MI, USA

The adaptive cruise control was updated when the recall was issued but still exhibits the problem of slamming on the brakes when passing a semi. The problem is actually getting worse, and happens more frequently. It now happens when going under a bridge. I have had it to 2 different dealers and contacted Ford and they all tell me that there are no computer error codes therefore it didn't happen. They also tell me that there is no recall because I already had the recall service performed. This truck is not safe, it will kill me or whoever is unlucky enough to be following me. Ford doesn't seem to care because they have already performed the recall service.

- North Ridgeville, OH, USA

My adaptive cruise control system has been updated according to the recall that was issued but I still have the same issue with the truck slamming on the brakes when passing a semi-truck.

- San Antonio, TX, USA

On Friday 10/28 while driving down the interstate at about 55 miles/hour at approximately 6:30pm with vehicles ahead of and behind my truck, the vehicle began to give a number of check engine alerts, at which time the engine rpms dropped to very low levels and began to stall and the accelerator no longer responded. Had truck towed to the nearest dealership within the hour. I was very lucky in this situation, for had I been in a construction area or on a bridge, the situation could have been much worse. This same situation occurred on the evening of 10/2 while driving 40mph down a state road near my home and according to the dealer who attended to the issue, the brake module had failed which caused the symptoms to arise. In that instance, the accelerate failed to respond and the engine began to stall, which it did when I pulled to the side of the road. They replaced the module a few days later. In addition, the driver side door vibrates and does not latch properly. Two dealers have failed to resolve this issue to date and I believe it is a safety concern that has largely been dismissed by the service technicians and dealerships involved. Despite numerous documented attempts to resolve this issue with Ford customer service, they have ignored this concern, have failed to respond to me in a timely manner, and declined a buyback request. I am submitting lemon law documentation for the vehicle during the week of October 31. I have spent hundreds of dollars on rental vehicles during attempted repairs to the doors and the brake module since Ford claims they will not cover the cost of rental vehicles during warranty repairs. Repair documentation attached pertains to repairs for 10/2 occurrence since the dealership has not yet had an opportunity to inspect my vehicle since it was dropped off yesterday evening. I will gladly provide info once received.

My fiance and I were driving down the highway, with no cruise control on, and suddenly my sensors go off as if I was about to hit something. Then after a second (probably was only a split-second, but it felt like forever), it went away. If adaptive cruise control would have been enabled, this would have caused the brakes to automatically press (I know because this has happened to me before). I was passing a semi, if that helps. This is a very dangerous issue (sensors thinking they are going to hit something, when it should be nothing). I wish I had a video of it happening, but it only has happened 3 times for at most 3 seconds in the the 1.5 years I have owned the vehicle.

While driving vehicle on highway and going to pass another vehicle when passing all of a sudden the vehicle will go from 70 mph and drop to around 40 mph with out no indication it's going to do this. Now this vehicle will do this anytime on highway you don't have to be passing anyone.

- Marinette, WI, USA

Vehicle brakes suddenly when on adaptive cruise control, particularly near semis hauling containers. Vehicle was recalled for this previously and still exhibits unsafe braking at highway speeds.

- Vestavia, AL, USA

Despite being in the dealers repair shop for warranty work for 33 days including a factory recall on the adaptive cruise control, the unit continues to malfunction. The latest event occurred on August 24, 2016 while traveling at 77mph with the adaptive cruise control engaged. Without warning or cause the collision control system fully deployed to include hard braking, windshield warning lights, instrument cluster warning, and audible warning. Result is that the vehicle dramatically slows very quickly creating a potentially major problem if there were vehicles following closely behind. This in addition to the sudden nature of the warning and vehicle "take over" by the system could cause momentary driver panic! dealer has stated a willingness to work on the vehicle again, but says they can only re-do what they have already done multiple times.
