Adaptive Equipment problems of the 2015 Ford F-150

While using the adaptive cruise control on my 2015 Ford F-150 (king ranch), my truck will confuse a dump truck as a stopped or slow moving vehicle in front of my truck. This will happen if a dump truck is in the lane beside me or in opposing lanes. This occurs at sow and high speeds. Multiple times this has occurred at 65mph+ in traffic. The truck will very abruptly apply the breaks and the collision warning system will alert. This has almost caused very serious wrecks due to the speeds that it often occurs. This is also not a seldom occurance, it happens every time I pass by a dump truck. It will occur on any and every street. I took the vehicle to a Ford delearship and their solution had no effect on the issue.

Adaptive cruise control occasionally causes f 150 to make an emergency stop even though there is nothing in front of truck on a clear, sunny day. The truck was doing 70-75 mph 3 times when this occurred.

My fiancée 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.

I received a recall notice from Ford telling me to bring the truck to the dealer to have the adaptive cruise control reprogrammed. I did have this work done. After the work was done I had an incident where I was passing an 18 wheeler and the truck set off the collision warning alarm and applied the brakes hard. If someone was following closely it would have been a collision. There was no traffic in my lane for at least 1/4 mile ahead. Ford has not been helpful in resolving this issue and their only suggestion is to turn off the adaptive cruise control. I paid a lot of money for what I feel is an important and useful safety feature and want Ford to fix the system so it will not malfunction and possibly cause a rear end collision.

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.

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.

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.

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.
