Driving approximately 20 miles an hour, gently applying the brake as I was approaching a stoplight when the brake suddenly engaged forcefully causing the car to jerk to a stop unexpectedly. There was a warning across the dash that said " forward collision is not available" and that disappeared. A local dealership said this was an abs issue and reprogrammed it.

What happened: on [early July 2026], while towing a cargo trailer at low speed, the electric parking brake engaged unexpectedly. The brake continued to engage repeatedly throughout the duration of travel. Eventually, the parking brake circuit lost power entirely, which is when the repeated engagement stopped. What component failed? the rear axle wiring harness (part of recall 23s35). The harness had chafed against the rear axle housing, causing an electrical short that resulted in repeated unintended parking brake activation. The short eventually compromised the entire circuit, causing loss of power to the brake. How was safety put at risk? a towing vehicle with an unexpectedly engaged parking brake creates immediate risk of loss of control, especially while actively towing cargo. The repeated activations while operating the vehicle could have caused the trailer to jackknife or the truck to slide. This malfunction occurred despite a prior recall repair performed in quebec under the same recall number (23s35). Confirmation: both north star Ford duluth and benna Ford duluth confirmed the diagnosis. Ford canada opened a claim acknowledging the failed recall repair.

I am filing an emergency complaint against Ford motor company for failure to provide a safety recall remedy within a reasonable timeframe under 49 u. S. C. Chapter 301. My vehicle has an active safety recall (recall 20s31) for a compromised brake master cylinder, making it entirely unsafe to operate. The vehicle is currently grounded and inoperable at my residence. Ford corporate has kept the required repair parts on a national backorder for over 3 months. On August 18th, Ford corporate sent me a formal written denial explicitly refusing to provide a rental vehicle or alternative transportation while my truck sits stranded. Ford is forcing me to choose between driving a vehicle with known catastrophic braking failure or having no transportation, actively violating federal recall compliance guidelines.

On July 6th, I was in my 2016 Ford F-150 at a stoplight after driving 200 miles in mountainous roads when my brake pedal got soft and went to the floor. I immediately shifted into neutral and waited for the light to turn so I could ease into a parking lot. Once parked, I noticed fluid on the ground and on the inside of my front passenger tire. I called for a tow and had it sent to a local repair shop. The repair shop told me that the right front brake line failed causing loss of brake fluid. The cost of the repair was $495. 00. When I called the local Ford dealership they told me that they could schedule me for July 31, 2026. I had the local repair shop do the repair. I did not have a brake fluid warning light come on while I was in the truck. My truck has 95,262 miles on it at the time of this incident.

The contact owns a 2014 Ford F-150. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop as intended. The contact stated that the brake pedal was depressed to the floorboard, and the vehicle rolled to a complete stop. No warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a leaking brake cylinder. The contact was informed that the brake cylinder was leaking onto the brake booster. The contact was informed that the brake cylinder, the brake booster, and the brake fluid reservoir needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 170,000.

Nhtsa / center for auto safety formal complaint vehicle information: * year / make / model: 2014 Ford F-150 * component category: service brakes, hydraulic / anti-lock brake system (abs) * affected part: abs hydraulic control unit (hcu) / valve assembly (part # dl3z-2c215-a / dl3z-2c215-c) incident / issue summary: I am reporting a critical safety concern involving a failure of the anti-lock brake system hydraulic control unit (hcu) on my 2014 Ford F-150, combined with an indefinite manufacturer supply chain failure that renders the vehicle unable to be repaired to safe operating standards. The electronic abs control module on my vehicle was inspected and rebuilt to functional specification; however, diagnostic testing confirmed that the internal mechanical/solenoid valves within the hydraulic control unit (hcu) assembly are stuck/failing. This internal valve failure disables key safety features, including anti-lock braking (abs), electronic stability control (advancetrac), and traction control. Upon attempting to purchase an original equipment manufacturer (oem) replacement hcu assembly through Ford motor company and authorized dealerships, I was informed that the critical safety part is on an indefinite nationwide backorder with no estimated delivery date (eta). Safety risk & regulatory impact: 1. Loss of safety features: without a functional hcu assembly, the vehicle operates without active abs or advancetrac traction/stability control, significantly increasing the risk of wheel lockup, vehicle skidding, and loss of directional control during emergency stopping or adverse weather conditions. 2. Unavailability of safe parts: due to high failure rates across 2009–2014 F-150 models, the replacement supply chain is completely exhausted. Independent repair facilities refuse to install unverified, used, or salvaged junkyard units due to severe liability and safety risks. 3. Indefinite stranding / unsafe driving: owners are forced to either leave their primary vehicle.

The vehicle has a documented, active transmission failure code p0720 relating to recall 26s28 (NHTSA campaign 26v237). Per pages 3 and 4 of Ford's official part 573 safety recall report, dealers are explicitly required to bypass the software wait and replace the physical lead frame hardware if a vehicle exhibits this code prior to the software's release. The local franchise dealership (mccombs Ford west in san antonio, TX) and Ford corporate customer relations are both actively refusing to honor this hardware safety remedy directive, forcing the vehicle to be grounded on the dealer lot due to the severe risk of high-speed rear-wheel lockup, while denying mandated alternative transportation support. Furthermore, the dealership has failed to execute the safety remedy for open brake master cylinder recall 20s31 (NHTSA campaign 20v332000), which presents an immediate risk of a sudden loss of braking pressure.

Issues with my 2025 f150 tremor when I applied my brakes firmly, really not that hard ( not hard enough to skid) my truck locked into park and I wasn’t even able to put it back into a gear with a flashing message! couldn’t get it back into gear for about 30 sec to 60 sec until a message stopped flashing. Had this happened in traffic or on a freeway this could have been really bad especially in traffic. Very dangerous!.

While towing a 6000 pound travel trailer 6/21/26, the brakes on the trailer failed. A trailer wiring fault message came up on the dash each time I braked. It is available for inspection. How was our safety put at risk??? stopping distance was increased substantually. When you need to stop, you need to stop! the truck has been brought to the dealer 4 times prior to this for the same problem. One of those times was for the recall on the trailer brake, may of 2026. The first time the truck was taken to the dealer for the warning message was April of 2025. The trailer was taken to the RV dealer after the incident (on my oct 2025 visit, the dealer told me the problem was with the trailer. I wanted to rule that out). The RV dealer found no problem with the trailer brakes, and determined the problem is with the truck. The truck was then taken to the dealer July 23 with "trailer brake module fault" message every time it is started. It remains at the dealer now. They believe it is the trailer brake control module. The module is on backorder with no estimated time for repair.

The master brake cylinder and components thereof are leaking and failing, leading to decrease braking power. Yes it is available for inspection. But Ford says my truck is not covered under the recall 20s31. Having this problem puts my family in danger every time we drive this vehicle, I have 3 young children 11,8, & 6 years old. There was no warning light or message prior to the failure. When I called Ford they said it was not covered under the recall and basically it was my problem for repair.

The driver's side rear light is full of moisture and some water. It is available for inspection. The Ford dealership in beeville texas coastal bend Ford inspected it already and informed me that it would cost $1,400 to replace and that it was only going to get worse. They also informed me that Ford allows a certain percentage of moisture and water to be in there safely. When you see the pictures this is definitely unacceptable and unsafe. This is causing the reverse lights to flicker intermittent. The moisture accumulation inside the lights can result in inoperative or flickering reverse lamp function. Inoperative reverse lamps may reduce the awareness of other motorists or road users of the driver's intention to operate the vehicle in reverse gear increasing the risk of injury or crash. I bought the vehicle from a Ford dealership in austin texas less than 10 days ago. I reported it to them and they stated it wouldn't be covered under warranty. The best assessment in my opinion of cause is going to be microcracks in the outer lens. Because my truck is a 2023 Ford F-150 king ranch, and there is a known recall for the same issue for 2022-2023 lariat and platinum models, so this can't be a coincidence. Refer NHTSA recall number 23v-418.

Truck suddenly reported abs issue while driving. Traction assist light came on. Parking brake light came on. Steering assist failure message appeared. Now the power steering is not functioning. I know of 2 other people with near exact issues on a Ford and a Lincoln. There is also a pending master cylinder recall that Ford said the didn’t have parts for and still haven’t heard back from them on that. Please investigate this dangerous situation.

My 2014 Ford F-150 previously received Ford's brake master cylinder recall repair under the previous owner in November, 2016. On xxx, at approximately 108,372 miles, we were towing our travel trailer and had just begun a planned vacation. Within approximately five minutes of leaving home, a warning chime sounded and a "brake fluid low" warning appeared on the instrument panel. I immediately exited the roadway and pulled into the nearest gas station to determine the cause. Within moments, the brake pedal traveled completely to the floor, leaving the vehicle with virtually no braking capability and making it unsafe to operate. Because the truck was towing our travel trailer, we had to disconnect the trailer in the gas station parking lot. The truck could not be driven safely and had to be towed to kent parsons Ford in [xxx]. My son had to bring his own truck to tow our travel trailer home because our truck was no longer capable of doing so safely. Kent parsons Ford inspected the vehicle and documented the following diagnosis on the repair order: "verified customer's concern. Found master cylinder seal failed and filled booster with dot fluid. " the dealership replaced the brake master cylinder, brake booster, brake fluid, and related components. The failed components may no longer be available for inspection because they were replaced during the repair. I paid $1,793. 38 for the repair. The dealership's diagnosis documents the same failure mechanism described in NHTSA recall 20v-332 (Ford safety recall 20s31), involving failure of the master cylinder seal that allows brake fluid to leak into the brake booster, reducing braking performance. Because this vehicle had already received Ford's recall remedy in November 2016, I am submitting this complaint to document that an authorized Ford dealership identified the same failure mechanism after the recall repair had already been completed. I respectfully request that NHTSA investigate. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C.

My 2021 Ford F-150 intermittently displays the warning message “reverse brake assist not available – see manual” when the vehicle is placed in reverse. When this message appears, the reverse brake assist / parking collision warning feature is not available, which may reduce safety while backing up. The vehicle was inspected by a Ford dealership. The dealership confirmed dtc u3000:49 in the ipma module and identified Ford TSB 23-2040 as applicable to the concern. The dealer stated that the repair requires an ipma software/module update and calibration. The quoted repair cost was approximately $1,100. This appears to be a software/programming-related condition affecting a driver assistance and brake-related safety feature, not normal wear and tear or a failed mechanical component. The warning is intermittent, but it has appeared multiple times. The vehicle is available for inspection upon request. No crash, injury, or fire has occurred. Ford customer support was contacted and case number xxx was opened. Ford advised that no active warranty, recall, or customer satisfaction program currently provides repair cost coverage, and that because this involves reverse brake assist, I may choose to file a safety concern report with NHTSA.

Master cylinder leaked and got a low brake fluid level warning and within one mile lost brakes with pedal depression all the way to the floor. Ford has a current recall for other makes and models which appears to be a manufacturer defect. My truck is currently in the dealership getting repaired.

My 2017 Ford F-150 is subject to safety recall 25v236 / 25s37 for a faulty brake master cylinder that can leak fluid and cause a loss of front braking function. I contacted the dealership to have the safety repair completed, but I was informed that the necessary replacement parts are on indefinite backorder with no estimated arrival date. No interim safety defect remedy or loaner vehicle has been provided by the manufacturer. I am forced to drive a vehicle with a known, critical braking defect, posing an immediate safety risk to myself and others on the road. The manufacturer has failed to remedy this safety recall in a timely manner.

In November of 2025. I took my truck, 2017 F-150 3. 5 liter engine, to crest Ford in flat rock mi. There was a recall on the master cylinder (25s37). On 5-26-2026 we were following a friend to take his car to dean arbour Ford in east tawas for service. While trying to slow down for a turn my brake pedal went very soft almost to the floor. I was able to slow my truck down enough to make the turn. I then proceeded very carefully to the dealer. It was all country roads with no traffic. By the time I got to the dealer my brake pedal went all the to the floor. I almost had to use the emergency brake to stop. If this would of happened on the expressway we could of been killed or killed someone else. There was no way I could of stopped in an emergency. Upon investigation the new master brake cylinder that was put on in November of 2025 failed. I was told they don't know how long it will be to get a new part because Ford requested all the new master cylinders to be returned. So it sounds to me that there could be alot more vehicles with bad master cylinders that customer had replaced and do not know they are bad. I was having no issues with my brakes on the old master cylinder. I am also being told that it's a warranty issue because the recall on it was closed when the master cylinder was replaced in November of 2025.

While driving this vehicle, the brake line was cut after making contact with the a arm assembly, at the highest point on the line. I immediately lost my brakes as the brake pedal went to the floor. I am extremely lucky that I was able to stop within the parking lot that I had just entered and did not have to make an immediate stop.

Tried to turn on vehicle one morning and it would not start due a parking brake error message & a warning light on the dashboard. The message on the screen behind the steering wheel stated “park brake fault service now” and there was a clicking noise heard coming from underneath the truck. I tried to reset the parking brake by pressing and holding the button as indicated online but it didn’t work. The brake also physically revolted at me pressing down on it and would stutter/thump and not let me press it down fully without heavy resistance. The clicking noise continued randomly even when I was not in the vehicle. Then the door locks stopped working with my car keys, I could only open the drive door manually. I had no means to jumpstart my battery. I called Ford local dealership to come check the issue incase it was a recall issue that had not been reported for my vehicle yet. They are scheduled to come Monday 6/1/26.

- master cylinder leaking into booster pump. ~lost brakes going 65mph, had to drive into a grass area to slow down. No warning lights until I lost all brakes. - transmission hard shifting and unreliable gear selection ~ this truck has missed gears when passing intersections and has almost caused a wreck multiple time. Transmission is unsafe for users to drive with.

The contact owns a 2016 Ford F-150. The contact stated that while driving 40 mph, the brake pedal was depressed and went to the floorboard, and the vehicle lost braking functionality. The vehicle was pulled over to the side of the roadway. The contact referenced notifications of NHTSA campaign numbers: 22v150000 (service brakes, hydraulic), and 17v652000 (latches/locks/linkages); however, the vehicle was not repaired because the parts for the recall repairs were not yet available. The vehicle was towed to dealer and was diagnosed with catastrophic brake master failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 140,000.

I was driving by and received multiple warnings about brakes. Brake assist, one pedal driving, reverse brake assist, general brake warning. After the came on the brake were spongy with a hard brake after applying more pressure to the pedal. I needed to apply more pressure because the car was not stopping. I almost hit various cars on the way home because there is certainly an adjustment needed to my braking habits. Very dangerous and unsafe. I took the truck to the dealership and quoted me around $2,500. This is something I have no control over and see that there is a recall on this issue for a 2025 model, but my vehicle does not fall under this recall.

I was on the highway doing 70mph and went to break and I had no brakes. I was terrified. I kept trying and I got it to break and pressed again and lost them again. Eventually the pressure on the breaks returned. The remaining ride home was just scarey.
