The electric trailer brakes only work intermittently. This results in dangerous situations where they fail without warning. An update was made in 2022 but failed to fix the issue. I have been on forums where many others are still having issues just like mine. It's very dangerous and needs to be addressed.
The Brake Pedal must be pressed very hard and the Pedal travels further than normal compared to my 2020 F150. The dealer told me the Brakes are OK but I can’t believe that Power Disk brakes don’t stop the vehicle easily. There’s is also extra brake necessary to come to a complete stop !

My 2021 F150 XLT with 19,000 miles has never had functioning trailer brakes. Initially I was plagued with constant trailer wiring fault / trailer disconnected issues, and zero slide or pedal brakes, when trying to tow a travel trailer. Two separate dealerships initially dismissed my concerns because it passed their trailer simulator test. Eventually, Ford replaced the trailer wiring harness under warranty. After that, I had intermittent slide brakes that would work, but I never saw any brake output when using the pedal brakes, regardless of gain setting. Ford then replaced the trailer brake controller, which worsened the issue: once again I am getting trailer wiring faults. My slide brakes are extremely hit or miss, and when they do engage they catch and release several times. I still have zero brake output when using the pedal brakes regardless of gain. The dealership consulted a Ford engineer and assured me that my truck is perfect, I should not expect to see brake output for pedal brakes, and all is working as designed. They blamed my trailer. I demanded to test my trailer with a different F150 from the dealership and it works flawlessly - brake output on both slide and pedal brakes, no error codes. It is horrifyingly obvious that I have never had ANY trailer braking functioning with my pedal brakes now that I have compared the braking distance in the loaner truck to my truck. If I had believed Ford, I would be towing a 7,500lb trailer with zero idea that I did not have any trailer brakes. Dealership and corporate are both kicking their feet on a potential fix to this horrifyingly dangerous trailer brake problem.
Park/Emergency Brake system light illuminates and system engages when vehicle is placed from drive to park, and when system is shut down the light illuminates and engages. Also, when vehicle is started the park brake light shows to be engaged. When the vehicle is put in reverse the light is still illuminated while the vehicle is backing up. The light stays on while the vehicle is in backward motion. Safety concerns for me and my family are: 1. What if the Park Brake engaged while driving at normal speed - what could happen? 2. With vehicle parked and brake system engaged driver should not be able to put vehicle in reverse and back up without disengaging brake lever. The vehicle was taken to the local dealership service center twice to try to get resolution of the park brake light issue. They were unable to duplicate the issue and stated that according to Ford's maintenance policy there was nothing more that could be done. We have tried to contact Ford through their main customer service phone number. We literally spent hours on the phone trying to reach someone who could help us with the issue, but no one had an answer for us. A case file was made by Ford Customer Service and marked "RESOLVED". It has not been resolved. As stated, the park brake light started showing up in February 2022. As of this time there has not been an incident, but I can't rule out that something might happen. I think it should be addressed by the dealership and/or Ford engineer with more interest than just a dismissal attitude.
This is a link to the Dashcam footage. Traveling 45mph in stop and go traffic. I braked (indicated by my hood dipping downwards) but failed to stop. Possible defect? Haven't had my truck back since the accident on 6/24/2022. https://youtu.be/HL7Iau0463I
When traveling on a divided highway in the left lane with no vehicle ahead of me, as I am passing a vehicle in the right lane, just when I am about even with that vehicle beside me my truck applies the brakes firmly and unexpectedly. There is no associated warning message on the instrument panel display or audio alert like there is when it goes into collision avoidance. When it happened the first time I was very startled and worried it saw something that required braking but as it happens almost every time I pass someone I am getting used to it.

I was driving with my wife and our one month old baby on I-25 in Albuquerque on a hot day (truck screen indicated 106 F) when suddenly the AdvanceTrac traction control, forward pre-collision braking, adaptive cruise control, and ABS system warnings all came on the dashboard. At the same time the brake pedal went limp (no braking action for the first ~50% of the pedal press). I slowed the truck by coasting for over a mile and picked an off-ramp that I expected to be empty before getting off the highway. Upon exiting the highway, I pressed the brake pedal all the way down and at 90-95% of the pedal compression the brakes finally engaged but locked up the rear wheels leading us to skip and skid across two lanes. We were able to come to a stop in the middle of the ramp and then gently moved over to the side of the exit, again locking up the rear wheels when we came to a stop. Upon turning the truck off and turning it back on again everything went back to normal suggesting that it was some subsystem that caused the electronic brake booster and ABS to become unresponsive. After a week at the local Ford dealer, the service technicians were able to find the error code C05CF. This error code appears to be officially only triggered by "Brake Master Cylinder Piston Position Sensor "B" -This DTC sets due to incomplete or improper module programming procedures." Which suggests this problem may have been lingering for over 30k miles of use. Ford technicians updated the traction control module firmware, body control module firmware, and then reproduced the issue leading them to perform an ABS system calibration which they claim fixed the issue. It is claimed that no component replacement was necessary, only software updates and calibration. Full dealer notes attached as .pdf It's crazy to think a software bug caused our brake system to almost entirely fail on the highway, particularly with an error code that should only have been able to been generated at the factory.
Have had squeeking breaks since receiving the truck a year ago. Brought in and was told to watch for a letter they don't have the part that my breaks are safe but the squeeking has gotten a lot worse. Also the dash board lights turn on and off when the car is off. The other day driving at speed on the expressway the whole dash board turned off all gages went to zero than rebooted. I was coasting trying to figure out what was happening so not sure if I lost power. 3 faults were sent to my phone. Restraint fault abs fault and tire pressure fault all showed up.

My emergency brake engages in its own. It has done it more than 20times since I have owned the vehicle. The first time it happened was about a month after purchasing. The last time it engaged I was pulling into a parking spot a couple weeks ago. Sometimes it come on when parked and other times The brake light on the dash will flash at me if I am in motion as it engages. When I disengage the brake I can hear the noice as it retracts. I assume typically there is a safety if it engages at high speeds but If this can have a glitch it makes me nervous if it would engage at highway speed and cause an accident. I have small children that ride with me and makes me nervous. I have brought it to the attention of the dealership I bought the vehicle from and they could not find anything wrong. I plan on taking it to a Ford dealership closer to my home as I drove a distance to purchase my vehicle. I believe this to be a huge risk if it would lock up while driving.
1) Pre-collision assist not available---- when starting after vehicle has been sitting off for one hour. Service AvanceTrac----when starting after vehicle has been sitting off for one hour. Hill start assist not available-----when starting after vehicle has been sitting off for one hour. Check brake system-------when starting after vehicle has been sitting off for one hour. All these warnings appear when starting the engine after vehicle has been sitting off for one hour. Yes, it is available. 2) I don't know if I restart the vehicle and warnings do not reappear if the components at fault still work. 3) Don't think it was reproduced. Showed dealer photos of warnings displayed on my dash. Dealer said no fix currently available. 4) No 5) All these warnings appear on the dash when starting the engine after vehicle has been sitting off for one hour. First appeared after starting on multiple occasions.
After connecting my boat trailer, I had ZERO trailer brakes. The lights all worked, brake, running, signal-but no trailer brakes. I turned the integrated trailer brake gain to the highest setting-still zero trailer brakes.
The standard trailer brake controller does not function. I have tried it on 2 known trailers that function with other trucks and this truck's does not work.
when connecting my truck to a know working trailer the truck would not enable the trailer brakes. tried different vehicle and the brakes work fine.
I make a panic stop with my 5,000 lb boat, ABS light came on break light came on flashing warning light said to inspect brakes. Moved truck and found I had only partial breaking, carefully drove home with partial breaking.. At home all lights went out and brakes worked fine. Took to dealer they said a sensor went bad and they ordered part will be here in a few days. Truck only has 7500 miles on it, replacing a sensor does not fix the problem of a sensor that can at any time go bad again. This is a major design flaw similar to the original 121 brakes on trucks. This is going to get someone killed . There is no reason to install a sensor that can disable any part of the breaking system.
