Doing approximately 45mph, in freezing temps and light snow, approached a yellow light. Had plenty of distance to stop and began to apply brakes. Truck began to slow, but suddenly felt like the brakes let go or maybe hit a patch of ice. Let off and depressed the pedal again. The pedal went to the floor. I began pumping them which was slowing the vehicle, but I ended up in the middle of the intersection, narrowly avoiding a side impact with a semi and looking like a moron. My entire family was in the truck and this was very close to a disaster. Afterwards the brakes were soft and continued to do the same. When the pedal was held down it would slowly go to the floor, feeling like all hydraulic pressure was bleeding off. The initial occurrence happened on a city road in motion. Of course the truck warranty ended about 500 miles prior. This vehicle has been babied, only used for weekends. Being told by dealer that a seal failed in the master cylinder and possibly a hydraulic control unit. Estimate to repair is over $2500 to repair a very new vehicle that costs over $50,000.
2017 Ford F-150 brakes complaints
Page 4 of 5: complaints 71 to 100 of 116, newest first, as owners wrote them.
I was backing into my driveway and stepped on the brake to stop the vehicle and the brake pedal went to the floor - no brakes. I didn't have time to try pumping the brakes or stepping on the emergency brake. The vehicle impacted the garage door damaging it to the point that it needs to be replaced. The replacement cost is $1,833.33. The vehicle impact points were the plastic parts of the tailgate, bumper and trailer hitch. There was no visible damage to the vehicle. The brakes worked fine again after the incident. I had skyline ford check the brakes and they could not find any trouble codes or problems with the brakes during a test drive. I now don't trust the brakes and am concerned that it could happen again with more severe consequences.
Tl* the contact owns a 2017 ford f-150. The contact stated that while approaching a stop light at 35 MPH, she attempted to depress the brake pedal however, the brakes failed to operate as needed, without warning. The vehicle proceeded through the red light. The contact was driven to the residence and then towed to peoria ford (9130 w bell rd, peoria, az 85382) where the brake master cylinder was replaced due to a leak. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in the federal safety agency campaign number: 20v332000 (service brakes, hydraulic). The vehicle was repaired. The failure mileage was 24,613.
While coming to a stop in traffic my 2017 ford f-150 xl 5.0l started braking normally with solid pedal feel. However, as I continued braking and applying more pressure to stop the pedal suddenly became very soft and went to the floor. I had to release the pedal and reapply the brakes. Again, the brake pedal started out normal and then went soft again as more pressure was applied and I had to veer to the right to avoid rear ending a stopped vehicle. Luckily no collision occurred. The brakes continued acting this way until I was able to carefully drive it to a ford service center. This occurred on both city and highway driving when coming to a stop or trying to slow down suddenly due to traffic. My vehicle is currently in for repair at a ford service center.
Digital cluster malfunction, causing speedometer and fuel gauge to both display zero, loss of power to windows, loss of parking brake function, blacked out backup camera, no heat or A/C. Highbeams stay on and cannot be switched to low beams. All happened while the vehicle was in motion on a highway at 60 MPH.
Brakes extremely pedal sponge to the floor. Extreme brake stoppage. Vehicle was in motion and was able to stop slowly on city street. I sent it back to a near home to stay. Extremely close to collision. No damages. Replaced master cylinder to repair center. Dealership was not available.
Tl* the contact owns a 2017 ford f-150. The contact stated that brake pedal stiffened without warning which had made it difficult to depress the brake pedal while driving at various speeds. The contact had taken the vehicle to tindol ford (1901 e franklin blvd, gastonia, nc 28054) where an inspection was performed on the vehicle however, the dealer found no fault with his brakes or brake master cylinder. Upon investigation, the contact linked the failure to the federal safety agency campaign number: 20v332000 (service brakes, hydraulic) however, the vehicle was not included. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 27,000.*dt consumer stated he took the vehicle to a different dealer and had it diagnosed vehicle had a defective brake booster, parts were unavailable.
Loss of brake function while driving on highway. Pedal to the floor with no warning lights / chimes. Brake fluid reservoir appeared full - no external signs of leaks. Brake pedal had a mind of it's own! Brakes would work, then pedal to floor, then brakes would work, then not.......... Towed to dealer on 8/13/2020 8/14/2020 - dealer states brake booster failure with brake fluid leaking into brake booster. Johnson / sewell ford in marble falls, tx. No mention of master cylinder or brake vacuum pump involvement? (ecoboost 3.5 engine configuration) booster on back order, may be weeks to months! My build date (3/2017 at dearborn plant) is almost one year later than the build dates shown in the pending recall 20s31, but appears to be the same problem.
I was on a highway in rain on cruise control approaching an off ramp. My speed was 72 MPH as set by cruise control. I applied the brakes to disengage and slow for the off-ramp which is sharp. As I approached I started to apply more brake pressure. The vehicle began accelerating as I was going into the turn. I stomped on the brakes and the brakes went to the floor repeatedly while still accelerating. I navigated the turn at high speed with the back end breaking loose and fish tailing. I barely made it around and proceeded to hit the off button frantically. The truck shut down and I coasted to the side of the road. I had my 7yr old girl in the truck. It was terrifying. When I restarted the truck the cruise control was disengaged and the brakes worked
I was in my driveway sitting stationary in my vehicle buckling up to depart for the store. I put my foot on the brake pedal to push the start button. After starting I moved the shift lever to put the vehicle in gear and the vehicle started to roll and my brake pedal went to the floor. Because my driveway has a slight ramp to it the vehicle kept rolling forward, I kept hitting the brake pedal but the brake pedal kept going to the floor and the vehicle would not stop. As a result I rolled into a block fence across from my driveway knocking it down and damaging my vehicle. Vehicle was just rolling under its own momentum, no power to the drive train. No injuries, but fence was down and vehicle hood and other front end areas were damaged. I have no idea what caused the brakes to fail. Filed an insurance claim and had to have vehicle towed to dealer for body repairs and neighbors fence repaired.
Without warning, brake pedal went all the way to the floor, pumping brakes brought pressure and was able to stop. Upon inspection at brake repair shop, master cylinder failure was identified.
Tl* the contact owns a 2017 ford f-150. While driving approximately 20 MPH and attempting to stop the vehicle, the brake pedal traveled to the floorboard and the vehicle would not immediately stop. The vehicle was immediately taken to grapevine ford (8101 e. State hwy 114, grapevine, ford) to be diagnosed, but the cause of the failure was not determined. The manufacturer was not notified of the failure. The failure mileage was 5,000. *pm consumer stated he tried applying the brakes several times but brakes went to the floor and emergency brakes had to be used.
Driving from california to oregon through nevada on interstate when vehicle started to overheat nevada dealer would not even look at the vehicle. Informed ford motor company. Continued to oregon and then on to bozeman montana. Vehicle is now at bozeman ford having the motor dismantled for diagnosis. Was told there is a issue with the number one cylinder, ford corporation has not been of any help what so ever.
Went to grocery store and everything was fine. Came out of store and started truck and had no power steering. Along with error messages on display reading: service advantrac, hill assist fault, powersteering assist fault, also have ABS light on and cruise control quit working. Steering is very hard to turn and makes truck very unpleasant to drive.
Intermittent braking issue. Breaks do not have much breaking power. While setting at a red light more pressure needs to applied to the break pedal. In some instances the pedal travels an additional 2 inches. Loss of break holding power caused me to hit a trailer being towed in front of me. My bumper had to be replaced.
Dashboard warning message "park brake malfunction-service now" along with other brake system symbols. Multiple random occurrences, can happen upon starting, when running or any operating condition. First happened day after new car delivery and re-occurs up to present date. Authorized ford dealer service departments have attempted repairs six times but the problem persists. Typical photo attached.
Power steering went out, lane assist, hill assist, lane keeping it, braking assist have all stopped working. Abs light is on and I am getting multiple senor warnings.
Ford f-150 lost control and accelerated coming out of car wash tunnel. Car did not respond to brakes and accelerated into a building injuring driver and pedestrian.
I go to the ford dealership that sold me my vehicle for all maintenance. (cowles parkway ford, woodbridge virginia). On 10/22,2018, I had my truck serviced and it was noted that my brakes were in a "yellow condition." on 12/11/18 my vehicle received a mandatory virginia state inspection (with no mention of the brake condition). On 1/22/2019, I took my truck for a service to include tire rotation and was informed that the tires could not be rotated and the brakes could not be inspected because the "lugnuts were swollen." I admit that this sounded ludicrous--(I am a retired aircraft maintenance officer with 27 years service in the united states air force). When I inquired about this condition from the senior technician, he informed me that ford motor company has these lug nuts that swell due to water intrusion and freezing. I asked how I would be able to change a flat tire on the highway and was informed that I would not be able to complete this task because the lug nut wrench would not fit over the nut. Thus my tire rotation was not completed and my brakes were not inspected today and (my belief it did not occur during the mandatory virginia state inspection either. However, my complaint focus is that the lug nuts on my 2017 ford f-150 can not be removed. I believe that this is an unsafe condition and warrants a recall and replacement of all f-150 truck wheel lug nuts and request your assistance in this matter. I was told by the technician that ford motor company is aware of this issue but has taken no action!
Could not stop for red light and smashed into someonee
The rear brake calipers seized up causing grinding noises and excessive wear of pads and rotors in a very short amount of time. Gas mileage was also greatly reduced as brakes were being applied while driving. Ford replaced the effected caliper but cannot guarantee that the other 3 will not do the same thing saying it was a faulty part raising concern that they will go out after my warranty on a one year old truck expires in the next few months leaving me responsible for replacing the faulty parts out of pocket.
Ford motor company documentation (2017 rv & trailer towing guide) states this model of truck, with the ford 3.5l ecoboost engine, can safely tow 11,500lbs (maximum loaded trailer weight). Based on personal experience and consulting multiple trailer towing experts, this is a misrepresentation of the material facts and capabilities of this truck. Additionally, it puts unsuspecting drivers in an unsafe and dangerous driving situation.
Door latches repeatedly freeze during cold weather despite having been in for repair several times since the truck was new, including a service campaign designed to address this issue. The door latches will either freeze while the door is shut, preventing them from opening, or will freeze after the door has been opened, which prevents them from securely latching when you attempt to close them. This past saturday the door opened while I was moving the truck in the driveway, resulting in me falling part-way out of the truck while it was moving. They again froze that evening, creating a situation where I had to hold the door closed with my left arm.
Tl* the contact owns a 2017 ford f-150. While driving 25 MPH and approaching a stop light, the brake pedal was depressed and traveled to the floorboard. The vehicle failed to stop and crashed into the middle of the front driver side door of another vehicle. There was no warning indicator illuminated. The contact sustained arm injuries, but did not require medical attention. A police report was filed. The vehicle was towed to the contact's residence. The contact called larry h. Miller ford lakewood (11595 w 6th ave, lakewood, co 80215, (303) 232-2200) and was advised to have the vehicle towed to the collision center. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 10,000. The VIN was not available.
. Last sunday I got a 2017 f150 xlt stuck in a small two foot snow drift. Once I got stuck I tried rocking the truck, but the transmission would not shift from forward to rear ward without the truck coming to a complete stop. After several attempts I got a fault warning for the limited slip diff. The warning for the power steering, the ABS, the parking brake, the hill descent, hill start assist, park assist warning (which I do not have), advanced track warning (which I do not have) and 4x4 low. Additionally the truck would shift in and out of 4 high, but not 4 low. In 4 high no tires would move. In two high only the left rear tire would spin. Because of darkness and grizzly bear I had to wait until morning to walk out far enough to get cell reception. The temp never got below 34 degrees, but it did rain and snow all night. When the tow truck pulled me out of the drift (a total of 10 feet) everything except the power steering worked. It was not until the 3 rd day when the power steering suddenly started to work. The dealer will not see me until next week and I am afraid I will loose all the fault codes by then. Its great to have a 4x4 that only works on dry ground. Had this happened in the winter or further away from cell phone coverage it could have proven to be a life threatening situation
Brake pedal must be pressed at least 1 1/2 to 2 inches for braking to begin. At this point the brakes are not firm. Also, while on a downward grade or hill the brakes initially brake, but slowly lose pressure and have to be pumped to retain braking. I have taken my truck to dealership 4 times and was told that this common to all lariat trucks and they cannot repair. Obviously, this is a defect that ford should address immediately.
No break lights, backup lights, parking lights, turn signal lights in rear.
Sudden loss brakes in a hard stop. There are videos explaining the problem where the ABS unit goes into bypass and for one wheel; but then the value does not reset. This issue has happened to me 4 times while driving the car, and to my wife once. Taking out the ABS fuse, and thereby disabling the function solves the problem, as the bypass valve will not engage. However you lose the mandated feature of ABS. Detailed explanation found at https://www.youtube.com/watch?v=0r46_unyyk8. This started at 7,500 miles and continued until I disabled the feature when ford could not isolate and fix the issue.
While applying the brakes, it is very easy to simultaneously push on the throttle pedal. This has happened several times, one time resulting in a rear-end collision, this is my first ford and this problem has never happened in any of the numerous vehicles I have owned. I had thought that software was in place that would not allow the engine to rev with the brake applied. If not so, it would seem like a very good idea.
Tl* the contact owns a 2017 ford f-150. While driving 30 MPH, the brake pedal was depressed, but the vehicle failed to stop. The contact stated that the brake pedal felt soft. The failure occurred without warning. The vehicle was able to be stopped by repeatedly applying the brakes and using the trailer brake.
