problem #11

Oct 152015


  • 900 miles


When using the adaptive cruise control, and when passing large trucks, the F-150 suddenly brakes as if it were about to crash, yet there is nothing in front of the vehicle. This has occurred 6 times at full highway speeds when passing big trucks that are in in right lane. It is a little scary if someone is tailgating - the good part is that using the accelerator will stop the braking. I took it to dealer and they were clueless. I've only had truck 30 days.

I previously reported that my vehicle had repeated experienced improper activation of the adaptive cruise control (and sometime collision avoidance system) and sudden braking at highway speed when passing certain large trucks. Recently Ford notified me of their (saftey recall) field service action number: 15S29 and on 5 November 2015 I took my truck to my local Ford dealer where they performed the work for recall 15S29. I took my first interstate trip following the repair on 9 November, a total distance of 74 miles, during this trip the adaptive cruise control again activated my brakes one time unexpectedly while passing a large truck. The safety recall repair has not solved the problem with my truck.

The truck's adaptive cruise control system would brake for no apparent reason. I had the issued safety recall performed on the truck Nov 2, 2015. The dealership report said that the recall was performed and working properly. That evening the truck again started breaking for no reason. I had installed a dash cam the Saturday prior to the recall repair. I have video footage of what was going on in front of the truck that caused it to apply the breaks. I had the cruise control set at 51mph, the 2 distance spacing, and the truck slowed it self down to 39 mph then sped back up again. I know I cannot attach a video to this report, but I am have it available to email.

When using the adaptive cruise control, and when passing large trucks, the F-150 suddenly and without warning brakes as if it were about to crash, yet there is nothing in front of the vehicle. This has occurred three times at full highway speeds when passing larger vehicles in an inside lane of interstate highways. This sudden and unexpected braking has almost caused three accidents and very nearly caused me to lose control of the vehicle.

  • miles
When passing a semi truck on the left (semi is to the right of me) using the adaptive cruise control function, the truck slammed on its brakes and said collision warning. Car behind me almost rear ended me. This happens intermittently like 6 times in 3 months and only happens when passing a large semi and the semi is to my right. Only happens in day time and even then, only sometimes happens.

  • 1,400 miles
When passing a large truck on a 4 lane road, adaptive cruse detected a collision and applied full braking. This occurred as I was in the trucks full shadow. Again last week while on the expressway and passing a semi, my vehicle detected a collision and applied full braking, again while in the semi's shadow.

  • 2,000 miles


Adaptive cuisse control falsely detects potential collision when passing semitruck (18-wheeler) on interstate/freeway highways as speed of 70mhp. The brakes are automatically applied and collision warning message goes off in the dashboard center screen. This happens very frequently when passing semitruck, to the point that I either disable the cruise or get ready to punch the accelerator in order to prevent a rear-end accident in case someone behind me.

problem #4

  • 1,000 miles
While the cruise is set and traveling on the interstate, in this case 70mph, when I pass an 18 wheeler the adaptive cruise control senses an imminent collision while passing the 18 wheeler in the left travel lane. The adaptive cruise immediately alerts and engages the brakes. Fortunately, this has not yet resulted in a rear end collision in my case however I'm sure at some point it will with owners of these vehicles. This has happened twice since I purchased the F150 in January(2015) and both occurrences happened while passing a tanker truck specifically and while in the left lane- tanker truck was in the right lane traveling at a slower speed perhaps around 60-65mph. This defect to me appears to be very dangerous because if my F150 engages the brakes for no reason and there were to be cars behind me a rear end accident could likely occur on the interstate. Ford has been very slow in responding to this safety concern and has not came up with a fix for this issue. Many on internet are voicing concern however are told by dealers that the system is functioning as designed and sent on their way.

problem #3

Apr 222015


  • 3,000 miles
The truck is equipped with adaptive cruise control and collision alert systems. Intermittently, when traveling at interstate speeds with the adaptive cruise control activated and passing tractor-trailer sized vehicles, the adaptive cruise control will falsely sense another vehicle directly in front and activate the brake system, resulting in rapid deceleration of the truck and creating the potential for a collision from behind. When the system activates, there are no other vehicles in front of the truck, only in the adjacent lane. This has happened over half a dozen times, and has resulted in near rear-end collisions from vehicles behind the truck because of how rapidly the adaptive cruise control slows the truck. Passengers in the truck have been thrown into their seatbelts from the rapid deceleration of the truck. Luckily no one has been hurt, but this presents an extreme safety problem and has resulted in having to turn off the adaptive cruise control and collision alert systems. Ford has not successfully created a fix for the problem. This problem has been well documented at

problem #2

  • 2,200 miles
Adaptive cruise control was set and engaged on vehicle at 75 mph. My vehicle was traveling on inside lane of four lane divided highway and came up on slightly slower vehicle traveling in the same lane at around 70 mph. My vehicle slowed down and tracked the other vehicle for about a mile before coming up on a slower moving tractor trailer truck in the outside lane. As the vehicle in front on my truck passed the tractor trailer on the inside lane, it moved over in front of the tractor trailer to the outside lane to allow me to pass. Instead on speeding up to 75 mph, my truck started to brake before I disengaged the cruise control (around 65 mph). At that time, I was located beside the tractor trailer near the back of the trailer. A vehicle following me had to brake due my truck unexpected braking and slow down.

problem #1

Jun 022015


  • 3,000 miles
When driving at night in the far left lane going 72 mph with the adaptive cruise control on, the truck randomly slammed on the brakes and the red crash indicator flashed although there was nothing in front of the truck. If someone was behind me, it is likely they would have rear ended my vehicle. There seems to be a defect in the auto cruise control, although Ford believes this behavior is normal.
