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 www.F150forum.com/F118/adaptive-cruise-malfunctions-scary-299485/.

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.

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.
