Cruise Control problems of the 2016 Ford F-150

I erratically simultaneously receive a warning that adaptive cruise control is inoperative & collision avoidance is inoperative. Both indicate sensor is blocked when it is clearly not the case. Also receive arbitrary collision warnings. Both occur with no other vehicles in the vicinity. The systems works fine most of the time but then the problem appears "out of nowhere". Seems to be occurring in all Ford models with adaptive cruise/collision warning. May happen on the interstate or in town. There are hundreds of reports of this condition on the internet. Stopping, shutting down, and restarting will "fix" the problem for an hour or so or maybe even a few days until it occurs again. Again, the sensor is not blocked. I can't find a safety recall or technical service bulletin for this problem.

Cruise control will not disengage. Driving down highway with cruise control on and when I put foot on brake to slow down, cruise control does not stop and accelerator begins to speed up. Pulled over and had to keep foot on brake as accelerator continued to increase while stopped. Turned off vehicle, did not disengage. Turned off engine again and stomped on gas, break petals. Finally cruise control disengaged.

The truck was set on cruise control when I accelerated to pass a moving vehicle on a freeway. The truck would not stop accelerating when I removed my foot from the gas pedal; I had to break hard to control the speed. As soon as I removed my foot from the break, the car engine revved up again and quickly accelerated from 70 to 96 mph even though I was not touching the gas pedal. When I stopped the vehicle and put the truck in park, the engine continued to idle at a high speed. The diagnostic reader produced the error code "p068a - ecm/pcm power relay DE-energized performance - too early". I took the truck to the dealership and they were able to reproduce the problem. To fix the issue, a new battery was installed.

When adaptive cruise control on and passing a semi sometimes the truck brakes sharply slowing down.

I have a 2016 Ford f150. 4 times now the auto breaking system engaged for no reason. 3 of the times I was driving in cruise control down a straight section of highway 80 going to lake tahoe, the auto breaking system engaged for no reason while passing a semi truck. The latest auto breaking episode almost killed us, we were driving back from lake tahoe on hwy 80, (cruise control was not no), when we were passing a semi truck on a curve in the two lane highway going about 70 miles per hour when the auto breaking system engaged for no reason and slowed our truck down form 70 to about 35 miles per hour in just 1-2 seconds. . . . I was not able to override by flooring the accelerator for at least 2-4 seconds. . . . A semi truck behind us came within inches from rear ending us!! this issue needs to be addressed by Ford. Its a huge safety issue!!.

When driving the vehicle on freeways with adaptive cruise control enabled, if the vehicle approaches a vehicle in an adjacent lane (typically a larger vehicle like a truck with a trailer, semi, or tanker) the collision aid activates and heavily applies the brakes. If someone is following close behind me, as has happened in at least 4 instances, the individual will need to stop and make an emergency maneuver to avoid colliding. In both cases, the braking only lasted momentarily but was enough to reduce the vehicles speed 20-30 mph during that time. The vehicle has been inspected by Ford but they have said that there is nothing that they can do. For the time being, we keep this feature disabled until Ford can get this issue resolved. There have been recalls for previous years but ours is not included. Because of this Ford has said there's nothing they can do on multiple attempts to get the problem resolved.

While in motion, the adaptive cruise control and collision warning system will activate and apply the brakes with force for no reason. At 70 mph, this is quite dangerous and has almost caused several accidents. I have since deactivated the adaptive cruise. The same issue occurred with a 2015 model I had and was never fixed by Ford.

My 2016 F-150 plarinum with adaptive cruise control, runs up behind vehicles on occasions then brakes hard. If the other vehicle is a semi, as you attempt to pass him with adaptive cruise on, the car brakes hard and slows down on occasions. In addition to this problem, on 5 different occasions when coming to a bend in the road, the steering gets very stiff as if the power steering is inoperative. The is very briefly before the steering returns to a very sensitive steering , also very brief. The vehicle at this point is in a under steer condition which it corrects itself. This has occurred at least 6 times. My selling Ford dealer has twice checked the programing with 0 results. No codes- no problems when they test drive it. The vehicle has 3550 miles and I'm getting scared to drive it. This first problem is identical to the 2015 Ford F-150 problem. According to my selling dealer, my vehicle which I purchased 2/19/16 was built towards the end of last year, but my dealer states this has no bearing on my alleged cruise problems. My selling dealer is two rivers Ford in mount juliet, tennessee. An additional vehicle at their dealership has been reported by one of their salesmen to have the same problem to management, and the problem exists today is my understanding. The speed at which these problems arise is varied and on at least one occasion I was almost rear ended by a semi who was coming up behind me when the brakes applied themselves.

Adaptive cruise control braking issue. My new 2016 Ford f150 platinum edition pick up truck will automatically brake hard when passing some large trucks while operating in adaptive cruise control. The lane ahead of me was clear with no vehicles in sight in my lane each time this happened. The large trucks I passed were on my right and not in my lane or even close to the lane markers. The large trucks did not have anything hanging over into my lane. These dangerous braking events happened while I was driving on very good dry highways and freeways in arizona. I have no stickers or after market items on my new f150 truck. This hard automatic braking happened to me on four different occasions during the month of March. In each of the four braking events I was traveling between 65 and 75 mph on straight high quality roads in arizona. I was almost rear-ended the last time it happened so I'm no longer using cruise control. As of today 4/8 my truck is at the morgan hill Ford store in morgan hill calif for inspection of this dangerous problem.
