Service Brakes Problems of Ford F-150 - part 2

My truck thinks my parking brake is engaged so it constantly flashes the “brake” light, constantly chimes while driving and says parking break malfunction, talk to dealer. I brought it to webber family Ford in detroit lakes mn 56501 and they checked it over including the safety recall location for recall 23s35. They said it was not the recall location and I would have to bring it in Monday for another appointment. When I got it home that day I crawled under to check that location. I see visible green which usually means corrosion and the protection around the harness seems warm. I also noticed the "recall" was not completed how it is shown on Fords recall paperwork using the zip tie as a wear location so it isn't the harness itself. That is not how mine is. I have photos to prove that. I spoke with corporate Ford today and they said they can't re open the recall because it has been closed and it is past its 12 month warranty being it was done in October of 2023 before my ownership and at a different dealer. I don't believe it is fair to me the current owner to pay for the cost of a rerepair of a recall that was done incorrectly.

My Ford F-150 is subject to manufacturer recall number23s65/NHTSA recall number23v896. I asked for the repair multiple times, but the dealership repeatedly told me that the parts were on backorder. The hub bolt on my right rear tire cracked and the truck was making a high pitched sound. I took it to the dealer and they said the bolt was cracked and driving it in that condition is dangerous. The truck is not safe to drive, but the parts remain on backorder indefinitely.

Transmission would downshift unexpectedly causing me to brake and panic, the tool icon will come on dash, speedometer stops working and backup camaras failed, transmission locked up on highway and caused driveshaft to lock back tires. All around dangerous situation.

2017 f150 super crew 4x4 brought into dealership for brake master cylinder recall. ( no lights on dash) dealership changed both the master cylinder and brake booster at no charge. The same day the vehicle was picked up, I returned it to the dealership. The vehicle was having issues with keeping straight on the highway and when I slowed down when coming to a full stop, the steering wheel turned completely to 1 side on its own. These symptoms were not present when vehicle was initially dropped off. Dealership is now telling me that the abs module is bad and that I need to pay for that repair. The local Ford dealership submitted documentation (special service support center assistance request) to Ford to cover related damage, but request was denied. I called Ford corporate to re-open case and appeal decision. Ford corporate would not re-open. I requested a field service engineer to review my situation, Ford said no. I asked for good will assistance, Ford said no. I asked if Ford could do anything to assist, Ford said no. It has now been over 45 days without my vehicle. The steering wheel rotating on its own after braking is a critical safety concern. The local dealership has changed the recall to complete and left me with a vehicle that is not safe to use. They claim the abs module is bad and I have to pay out of pocket, but they have yet to provide any documentation or reports including any obd2 codes that indicates this is not as a result of the recall work performed. In summary, I left my vehicle at dealership for recall on master cylinder and after repairs the vehicle is having issues with related components that were not present before dropping off. All I ask is that Ford can assist by covering the needed parts and labor to get my vehicle back on the road performing safely.

I battled this for a year and then my parking break locked up while driving 70 on the highway! that’s the recall megee claimed they fixed I’m not rich single dad 100% of rhe time and I sure my kids everywhere daily, I do research call Ford find intact I had a recalll so im thinking it will get fixed! 6 weeks later they not fixed I was told 2 days now heritage and Ford won’t fix it they want megee Ford the certified service and dealer to pay for it.

I almost reck once a day as the whole system is messed up now! I feel like I’m being bullied and picked on because of my nationality.

I’ve now had two major safety issues with my 2024 Ford F-150 stx. 1. September 2025 – loss of acceleration while driving I was driving north at about 40 mph when my truck suddenly stopped accelerating. It felt like it went into neutral on its own. I pressed the gas and nothing happened — the truck just started coasting. There were no alerts, no warning lights, and no explanation. I had to safely pull off the road while the truck was basically free-rolling. 2. Most recent incident – emergency brakes slamming on in an empty parking lot when I was leaving a facility recently, I was driving slowly through an empty walgreens parking lot — no cars or obstacles anywhere around me. Out of nowhere, the truck’s emergency brakes slammed on extremely hard. It didn’t just happen once — the brakes locked up five times within about a minute while I was in drive. There were zero warning messages on the dash each time. The jolts were so violent that my son flew forward and hit the seat in front of him. My right leg slammed into the dash, and the impact was so strong I ended up in the er afterward with severe pain on my right side.

The contact owns a 2014 Ford F-150. The contact stated that while shifting into drive(d) and depressing the brake pedal, the brake pedal remained on the floorboard and the vehicle unintendedly moved forward. The vehicle was restarted, and the brake pedal was continuously pumped until it regained normal functionality. The contact stated that after the third attempt to shift into drive(d), the "low brake fluid" message was displayed. The vehicle was towed to an independent mechanic, but it had not yet been diagnosed. Additionally, the contact stated that there was condensation under the passenger’s side of the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 88,000.

Put the truck in reverse [from park] and when I braked the pedal went to the floor and took many seconds to stop the vehicle. Checked the brake fluid, very low, filled it, pumped the brakes until it was no longer to the floor, checked the fluid again and filled it again. Parked it then tested it 20 minutes later, brakes were to the floor. Took it to mechanic who added brake fluid and looked everywhere underneath for leaking, found no brake fluid leak anywhere. Checked online for recall on defective braking system and found this. Reference mfr campaign number: 16s24, defect summary: loss of brake fluid from the primary reservoir results in a complete loss of front brake function, increasing the risk of a crash. That's the problem. I have an appointment 11/3/25 with russ milne Ford who says they will replace the brake booster, fill the brake fluid & replace the master cylinder, if necessary, as per usual with this recall.

The powertrain/transmission is not receiving the signal from the engine to accelerate. It can be inspected. The vehicle is slow to accelerate or will not accelerate at all, causing lurching motions and slow movement of the vehicle. This can cause my vehicle to rapidly accelerate or me to slowly decelerate, causing me to possibly run into others or be hit by others. No one has reproduced or assessed the problem. The problem occurred multiple times before a warning message was displayed. The signal appeared after two weeks of the failure occuring.

The contact owned a 2025 Ford F-150. The contact stated that while driving at 60 mph, and while depressing the brake to stop the vehicle from hitting a stopped vehicle, the rear end locked up and did not slow down as intended, and the front of the vehicle collided with the rear of the stopped vehicle. The contact sustained a broken sternum and had a concussion, and needed medical attention at a later time. A police report was taken. The vehicle was towed to two tow lots, where it was deemed a total loss. The contact stated that one day she received notification of NHTSA campaign number: 25v488000 (service brakes, hydraulic), four days later in the mai,l and believes the failure to be associated with the unrepaired recall. The manufacturer was notified of the failure. The failure mileage was approximately 10,200.

Driving at highway speed when the low brake fluid warning light came up on dash. I managed to get the truck and trailer I was pulling to a safe location and checked brake fluid. I had little braking power. I had brake fluid brought to my location and refilled the reservoir. I inspected the brake system for leaks and there were none. I tested brakes and they appeared to function properly. I returned to the highway and within two minutes I completely lost all braking. The internet reports that there are recalls on some trucks for this problem but my search using my VIN does not show one, but I have the same brake failure described to those reports.

Hi there, I wanted to report a situation with my Ford f150 lightning I brought this monster truck last December'24 and everything worked until today when I hit a issue with the break me and my wife went to costco for weekend shopping, I was trying to park to a very comfortable parking position; after getting in, I reversed the car to make it align with the parking line. Right after that I changed the position to drive slowly role it forward to adjust my parking, the truck started accelerating forward. I pressed the break hard and hard it would not stop. Imagine its costco, lot of people around me, luckily it was trees and mulch area infront, and imagine its costco, lot of people around me, luckily it was trees and mulch area infront, and there was a traffic board. The truck hit the traffic pole and stopped hanging over the mulch area. Everyone around me was screaming and looking at me. Through traffic stopped and took diversion, I pulled back slowly, guess what, the car would not come back to the parking lot again. I press the reverse and accelerate to get back to the parking space, but car is still going forward, scary. I stopped the engine and again tried to reverse; it worked. I swear to god that I never hit the acceleration since it's a parking spot, why would I do that. . . Car still went forward, so it's a genuine bug in the Ford 150 which needs to be fixed, otherwise its going to hurt or kill people I still have loan to pay for this car, but after todays incident I will not take his car out again , unless Ford give me proper explanation and fixes. I read many similar stories in rediit, so I think this is real issue. Other wise why the car wont stop even I press th break pedal, remember I configure this car with one pedal, but still nothing worked. Any help in sorting this out is higly appreciated, I am more worried about the risk of the public's life with this kind of issues where I cannot stop the car even after pressing the break, its really scary.

I took my 2017 f150 pickup to aaron Ford in poway to perform the following: 1) resolve recall #25v236 Ford brake booster 2) provide an estimate for resolving the "wrench" cockpit display icon aaron Ford had my vehicle for 3 days they claim, investigating #2 and provided an estimate of $10,000 to rebuild a transmission with <85,000 miles. The recall was not investigated nor resolved even though the dealer had the required parts in stock. I would like to file a formal complaint on aaron Ford's failure to complete the specified recall work as request.

When you’re stopped and have the auto hold feature on, and open your door, the gear selector will automatically shift to park and engage the e-brake. Off and on, this will cause the brake system to fault and will tell you to service immediately. A couple other times it triggered randomly with just having the auto hold feature activated. It’s happened on and off since I got the truck new. I have a video of me trying to engage and disengage the parking brake and nothing happens. I have to start and restart the truck multiple times to fix it.

I own a 2025 Ford F-150 lariat equipped with the factory tow package. The truck was sold to me and later serviced under the representation that the trailer brake controller was functional. Duvall Ford in clayton, GA installed and programmed only a brake controller switch and assured me the trailer brakes were working, without performing a functional brake output test. The truck was later found to be missing the required trailer brake control module (tbcm), meaning no trailer brakes could ever function. As a result, I unknowingly towed a 30-foot travel trailer from north carolina to California, across multiple states with zero trailer braking, creating multiple dangerous situations and close calls. Upon reaching California, aaron Ford of escondido inspected the vehicle and immediately identified the missing tbcm. They performed the proper repair, with an invoice of $1,043. 00. The original dealer’s incomplete and incorrect service directly created this safety hazard. This issue may affect other F-150 trucks that were sold or serviced with incomplete brake controller systems due to Ford’s mislabeled parts catalog.

Complete loss of brakes. There was zero response from the brake pedal for several complete pumps to the floor. After about 4 complete "stomps", the brakes locked, resulting in a violent and sudden stop. At the time, the dash began flashing multiple warning messages about display failure and also abs failure and making many alarm sounds, further distracting me from dealing with a very dangerous situation. Had this occurred at speed and not at a fast idle speed, serious injury or death would likely have occurred. This is a xcelerate fleet vehicle, and fleet services took the vehicle to a non-dealership shop, which claims to have fixed the problem but could not complete the recall repairs. Fleet has only just today agreed to tow the vehicle to a Ford dealership for recall repair. This incident occurred on 9/26/2025.

Recall 23s35 is not showing up for my vehicle even though I have the exact same issue. Dashboard alarm and message "park brake fault service now" and it activates my brakes. I took it to the dealership while it was still going on, even after I shut the truck off.

Transmission dropped into first gear at 45mph. Rear end locked up while taking my kids to school. Output speed sensor in transmission. Lead frame issue.

While driving , brake pedal went to the floor causing vehicle to barely stop. Upon stopping and exiting vehicle noticed brake fluid on the ground and right side brake hose had ruptured. Vehicle had to be towed for repairs. Ford service department says entire brake line and hose must be replaced due to "fitting is swollen".

Transmission & brakes . . . Acting up.

The brake system on my 2018 Ford F-150 2. 7l ecoboost began failing around early 2025 with a brake warning light illuminating and the pedal feeling soft, signaling a problem. The brake fluid reservoir dropped low repeatedly despite topping it off multiple times with dot 3 fluid, indicating a persistent leak. By 09:52 am cdt today, September 10, 2025, the brake pedal lost all pressure, making the vehicle completely undrivable and posing a severe safety risk due to significantly increased stopping distances and potential brake failure. At 10:37 am cdt, thick white smoke started billowing from the exhaust each time the vehicle was started, likely from brake fluid leaking into the engine via the brake booster, a symptom matching Ford recall 25s37 (NHTSA 25v236) for a defective brake master cylinder seal. This failure endangers the driver, passengers, and other road users, as the truck is a primary vehicle, with the smoke suggesting a fire hazard and possible engine damage like stalling or misfires. The issue is reproducible, with the warning light, fluid loss, and soft/no pedal persisting since early 2025, worsening today with the smoke appearing consistently on startup. It has not been confirmed by a dealer or service center yet, as the vehicle is undrivable, but I plan to tow it to a Ford dealership for inspection under the recall. No manufacturer, police, insurance, or other inspection has occurred, as the smoke issue escalated this morning; prior rear left electronic parking brake actuator replacements in 2025 due to fluid leaks were done at home. The brake master cylinder and possibly the brake booster are the failed components, with the actuator issue likely related, and the vehicle is available for inspection upon request or at a dealership. Symptoms first appeared with the warning light and soft pedal in early 2025, followed by fluid loss, complete pedal failure, and smoke today at 09:52 am cdt.

The contact owns a 2014 Ford F-150. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed and went to the floorboard. The "brake fluid low" message was displayed on the instrument panel soon after the failure. The vehicle was taken to an independent mechanic, and brake fluid was added; however, the failure persisted while continuing to drive. The vehicle was taken to another independent mechanic, who was unable to determine the cause of the failure, and the vehicle was towed to a dealer. While at the dealer, the vehicle was diagnosed with a defective brake master cylinder and brake booster. The contact was informed that the parts needed to be replaced. Upon investigation, the contact linked the failure to NHTSA campaign number: 20v332000 (service brakes, hydraulic); however, the VIN was not included in the recall.

Vehicle drove fine to work and upon getting in to return home and staring the vehicle, the brake pedal was instantly spongy and low brake fluid alert displayed on dash. There was a difference in 9 hours from when the brakes were fully functional to having brakes were completely out and nonfunctional. Had vehicle towed to local dealership and their diagnosis was "master cylinder is bleeding into the booster" and booster "full of brake fluid. " this exact issue has been known and was supposed to be addressed but there have been numerous issues with the new parts installed after the recall leading to subsequent master cylinder/booster failures. Since it has already been "repaired" under the initial recall, the subsequent repair cost $1,300 including diagnostic.

While driving today, my Ford f150 manual light came on while I was driving and then break assistance. Light came on, and it told me to check the brake system. And immediately immediately the truck slammed on the brakes while driving. I almost wrecked with my two year-old daughter who is autistic in the vehicle. This needs to be fixed ASAP. This is very dangerous and could’ve been a lot worse this morning.
