Cruise Control problems of the 2015 Ford F-150 - part 1

Drive in the interstate I felt something tap my shoe and at the same time cruise control deactivated and the hill assist warning light come on. I then tried to accelerate and for a second there nothing happened and then acceleration came back on and it would cut out like traction control is kicking in. Pulled over on to the side of the interstate and found a broken plastic pin looks like a body panel pin on the floormatt. Me being a mechanic something told me to look at my brake light to see if there being activated with no pressure on the brake pedal . The lights were on telling me that this pin had to do something with the brake pedal and the brake light switch. Once I looked under the dash, I did find that this pin came from the brake pedal and was no longer pushing on the brake switch and that's what actually cause my cruise control to shut off and traction control kick in as I were driving on innerstate. I was able to temporarily fix the issue was a body panel pin that I by lock had in my glove box from other projects and was able to get back on the road and make it home . The issue is the this original plastic piece is a certain thickness that if you replace it with a thinner piece you still have the same problem and if you get this to thick you have to push harder on the brake pedal to activate the brake lights and deactivate crouse control, and that's were it can get scary going 70 mph on the interstate and not being able to deactivate the crouse connector. So I call the local Ford parts store and the issue is that this plastic pin can not be purchased by itself and that this pin has to be purchased with a $150 pedal. So I looked on the internet to see if maybe this is an issue with this vehicle and I found multiple complaints of the same issue and no recall form Ford for this issue witch in my opinion it's a safety issue. 2015 F-150 with 76000 miles.

On adaptive cruise control, since new, the vehicle brakes are applied when passing an 18 wheel truck/trailer (sometimes) causing a rapid 15-20 mph hard braking decrease in speed jolting and scaring the occupants of the Ford. Nearly rear ended several times. Have contacted Ford but they did not care nor were they concerned that this is a safety issue. Very dangerous going from 65 to 45 while passing another vehicle and cars are behind me. This is a random occurrence making it even more scary. This has happened too many times to count since 2015 and I am afraid to use the adaptive cruise control for fear of being hit from behind on the highway.

Tl the contact owns a 2015 Ford F-150. The contact stated while driving 50 mph with the cruise control activated, the steering wheel seized without warning. The contact attempted to depress the brake pedal however, the vehicle was difficult to stop. The contact stated after driving over a bump in the road, the contact was able to turn the steering wheel and depress the brake pedal to stop the vehicle on the side of the road. The contact stated the air bag warning light was illuminated. The contact continued driving to his destination. After driving 30 miles, the air bag warning light turned off independently. The contact stated while exiting the vehicle he started to smell electrical fumes. The vehicle was taken to joe hall Ford located at 1617 21st st, lewiston, id 83501, (208) 746-2391, and the mechanic was unable to duplicate the failure. The vehicle was not repaired. The VIN was included in NHTSA campaign number: 20v332000 (service brakes, hydraulic). The manufacturer had been informed of failure. The failure mileage was approximately 42,000.

This vehicle experiences exactly the same characteristics as the following NHTSA campaign number: 15v614000 yet is not subject to the recall. The vehicle has acted in this way at least 10 times, the most recent on June 24, 2020. The vehicle may fall just outside the previously determined manufacture date window that determined the recall pool. Ford will not perform the software update to solve this problem as the vehicle is not subject to the recall. Please reconsider the vehicles included in this recall as mine may have been missed in error. September 30, 2015 NHTSA campaign number: 15v614000 unexpected braking using adaptive cruise control a vehicle that unexpectedly brakes increases the risk of a crash. Nhtsa campaign number: 15v614000 manufacturer Ford motor company components forward collision avoidance potential number of units affected 33,481 summary Ford motor company (Ford) is recalling certain model year 2015 Ford F-150 trucks manufactured March 18, 2014, to August 6, 2015 and equipped with adaptive cruise control (acc).

Cruise control shuts off during operation. Intermittently will not turn on. Analog speedometer will indicate speeds in excess of 40mph slower than real speed. Stuck at 40mph when comes to complete stop.

While accelerating the vehicle to get to 55 mph the engine suddenly lost throttle response and began to run rough. Simultaneously the dash flashed that uphill assist was deactivated and flashed the maintenance wrench. Upon pulling the vehicle over and shutting it off and restarting it the vehicle ran normally. The frequency of this increased from once every couple of weeks to now up to 5 times in 10 miles. When it causes an obd code it is p2112. It occurs most frequently while accelerating to highway speeds but has also occurred while at highway speed and accelerating to village speeds of 30 mph. It has even occurred once while using cruise control as the vehicle was climbing a hill. At this time it is unknown what is causing the fault. An attempt has been made to clean the throttle body and the problem persists. A new throttle body is on order but has to be installed yet to see if it corrects the issue.

I picked up my 2015 Ford f150 on Thursday of last week because the master cylinder was leaking and caused my wife to lose her brakes while driving on the highway. I drove my truck to our family reunion about an hour and half away on Saturday which was 2 days after I had picked my truck up and the cruise control would not shut off by taping the brake. My wife and I were traveling on a highway and I was in the slow lane with the cruise set at 72mph. I was approaching the vehicle in front of me, so I looked in my left mirror and noticed a car coming up beside me. I was unable to pass, so I touched the brakes to disengage the cruise control and I looked back in my mirror again to see if the car beside me was going to pass me soon. My wife then said what are you doing? I told her I am going to pass this car in front of us after the car beside me passed us. She then said well you better slow down because you are about to hit the car in front of us. Here my cruise control never disengaged so I touched the brakes 2 more times and nothing happened. I finally had to slam on the breaks and it finally disengaged. I had almost rear ended the car in front of us. I then got into the fast lane and placed the cruise control on again and found out that I was unable to disengage the cruise control by tapping the brakes like you should. I had to push the brake pedal 2/3 of the way to the floor which at this point you are stopping on the highway. This is the third safety issue in less than 1 year that almost caused an accident and that it has been towed to Ford. My truck is currently at Ford. Dec 2018 throttle body went bad and shut off with my wife driving my truck, sept 2019 master cylinder went bad and caused my wife to lose the brakes while on the highway, and sept 2019 cruise control not working properly almost causing an accident.

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.

There is an existing adaptive cruise control safety recall open for this year, make, and model, but my truck also experiences the exact same issues described by Ford on their own site every time I use the adaptive cruise control: https://media. Ford. Com/content/fordmedia/fna/us/en/news/2015/09/30/Ford-issues-five-safety-recalls-and-one-safety-compliance-recall. Html I'm sure that the existing safety recall needs to be expanded to additional vins within the F-150 range of vehicles. It is extremely dangerous in the way it currently operates.

Adaptive cruise control sensor and braking activate in error when there is a large truck on the side of the vehicle. Vehicle will hard brakes as it thinks the car in front has stopped when there is no car in front of you. It is falsely seeing the truck in the other lane to your side. I had it into Ford for another issue and told them. They said there was "an update" but it is still doing the same thing. This is dangerous as the vehicle slams on the brakes by itself almost causing cars behind you to hit you. The vehicle should not hard brake due to a truck on the side of the car!. Just today my car did it twice on the highway. Once this morning and again on the drive home. I am driving at highway speeds, clear day, I'm in my lane and passing a slower truck on my right and the adaptive cruise braking slams on the brakes. It is intermittent and I'm not sure why its reacting to a large truck that is not in front of me. While it didn't result in a "crash" it could have if the person behind me hadn't been paying attention. This is a serious defect!!.

Multiple incidents have occurred where adaptive cruise control applies hard deceleration to the vehicle while at highway speeds without warning or without an object in front of the vehicle. Approx travel speed has been 65mph and vehicle collision warning comes on and instantly brakes causing a 10mph or more deceleration. It has happened on curves or when driving near a truck. Recent incident was moving from right lane to the left lane of a highway to pass a truck and another vehicle was following mine. As I approached the tractor portion of the tractor/trailer, my truck braked hard and the vehicle behind me nearly crashed into the back of my vehicle. The other driver wasn't expecting me to brake while passing another vehicle to its left. This has happened multiple times. I have contacted Ford and they admitted that there is a problem with the adaptive cruise system and that it was a safety issue but they had no plans to fix/recall the issue. Question - how many rear impact accidents/incidents/potential incidents will it take for Ford to address this serious unannounced braking issue. It is very unnerving to be driving at highway speed and then to be thrown forward for no reason because your vehicle brakes. Ford did acknowledge that this is a problem and yet does not wish to address it likely until there is death to lawsuit after which it will have been too late for someone. Please exert whatever pressure you can to get verification from Ford and have them address this problem with a recall before someone is killed. Thank you. Highway speed adaptive cruise control on on curves or straight roads near a tractor trailer collision warning/braking/rapid deceleration nearly causing multiple rear end accidents - many incidents Ford verified but refuses to fix.

Letter from congressman bilirakis on behalf of constituent re 2015 Ford F-150 safety concerns when the cruise control is applied his car would slow down instantly as if the breaks were applied. Updated 11/08/2017.

The contact owns a 2015 Ford F-150. While driving with the cruise control set at 75 mph, the vehicle started shaking and the speed reduced to 60 mph. The contact stated that it felt as if the brakes were being applied. The contact depressed the accelerator pedal and the rpms increased, but the vehicle failed to accelerate. The contact pulled the vehicle over and looked under the hood, but no issues were found. The vehicle was able to restart and operated normally. The contact stated that the failure occurred twice while the cruise control was engaged. The vehicle was taken to Ford of port richey (10715 us-19, port richey, FL 34668 (727) 478-0975), but the failure was unable to be duplicated. The manufacturer and a congress member for the state of florida were notified of the failure and a case was opened. The failure mileage was approximately 87,000.

While using the adaptive cruise control, the vehicle falsely detects an obstacle in its path and unexpectedly applies the brakes.

The adaptive cruise control sometimes thinks there is a vehicle in front of me when there is not and aggressively applies braking.

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.

The contact owns a 2015 Ford F-150. While the cruise control was activated, the vehicle braked abruptly. The collision warning indicator illuminated and a chiming sound was heard. The vehicle was taken to a local dealer (watertown Ford located at 1600 9th Ave se watertown, sd 57201) where it was diagnosed, but not repaired. The manufacturer was made aware of the failure and opened case number: 12350340. The failure mileage was 19,200.

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.

The contact owns a 2015 Ford F-150. The contact stated that while driving approximately 70 mph with the cruise control activated, the vehicle independently decelerated while driving next to other vehicles. No warning lights were illuminated. The vehicle was taken to a local dealer where unknown repairs were performed. The vehicle was repaired; however, approximately 7 years after repairs the failure reoccurred. The vehicle was taken to the same local dealer where unknown repairs were made. The manufacturer was not made aware of the failure. The failure mileage was approximately 25,000.

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.

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.

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.

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.

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.

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.

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.

While using adaptive cruise control mode at highway speeds both day and night my vehicles forward collision avoidance system has mistakenly applied the brakes suddenly reducing the vehicle speed abruptly. Night time instance was going under a expressway overpass center lane no other vehicles in area. Day time in hov lane and moderate traffic flow but no one within ten car lengths. Only 1000 miles on vehicle. I have deactivated the adaptive cruise control in vehicle settings. Vehicle just outside of production date of recall. Two purchased new 7/28/2016. To be reported to dealer.

The contact owns a 2015 Ford F-150. While driving approximately 40 mph, the vehicle suddenly experienced unintended acceleration and the accelerator pedal erroneously depressed to the floorboard. The cruise control was not operating at the time of the failure. When the brake pedal was depressed, the vehicle continued to accelerate. The vehicle was taken to the dealer where the failure could not duplicated. The manufacturer was not notified of the failure. The failure mileage was 72,000.

My girlfriend and I were driving down the highway on a sunny day at around 70 mph. I was using adaptive cruise control. There were other cars on the road, but none within distance to affect my speed/cruise control (they were all way ahead or behind). All of a sudden, for about a half second, my truck flashed the warning light and sound as if I was going to hit something, and it automatically pressed the brake for me. It was very scary and dangerous. Then it came out of the warning and we continued on our way (we were in a bit of shock). I of course turned off the adaptive cruise control so the vehicle was under my complete control. Thinking back, I'm wondering if the shadow from an overpass caused my truck to think there was a vehicle close and an impending crash. Either way, it was very unsafe, and I'm hoping it doesn't happen again to me, or anyone else.

While driving on the highway using the adaptive cruise control, the vehicle may falsely detects an obstacle in its path and may unexpectedly apply the brakes. This issue has been addressed by NHTSA campaign number: 15v-614, but my vehicle was not part of the recall. I believe my (and perhaps other peoples) vehicle should have been included in the campaign.

While using adaptive cruise control the car will inexplicably break when it sees shadows in the road. Usually happening while traveling under a bridge on highway. Car will drop speed from 70 mph to approximately 40 mph with sudden breaking?.

The contact owns a 2015 Ford F-150. While driving approximately 70 mph, the push start button was touched and the vehicle shut off while still in drive, causing the vehicle to slow down in the middle of traffic. The contact was able to pull over and restart the vehicle. The contact tested the failure at various speeds and the failure recurred. The contact spoke with the dealer who stated that there was no recall related to the failure; however, the dealer also stated that the cruise control needed to reprogrammed and further inspection was needed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 6,000.

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.
