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.

While driving with sound volume at normal setting (volume 8), speakers started to pop and static erratically, which startled me, almost causing an accident. The issue will randomly go away, no warning lights on screen or dashboard. The static and pop sounds still continued at volume setting one. The erratic static and pop goes away then it happens again 20 min later. My ears are ringing from the popping sounds

On March 24, 2023, I got inside my 2021 Ford F-150 Power Boost King Ranch Truck, Turned it on. Heard a loud popping sound. Began to drive away. Then all of a sudden there was a loud static sound. The sound was so loud like someone turned the volume to MAX limit and I began trying to turn it off. The radio was not responsive. I started to panic because I had all these vehicles around me and could not think correctly. It was affecting my decision making and all I could think of is turning off my phone, pressing the Power On + Next Track button to hard reset radio, etc. Nothing worked. Loud static sound would stop. Radio wouldnt turn off. Next thing you know Im on the expressway trying to get off because obviously nothing worked. After around 20 minutes, I finally pulled over. Turned off my truck. Then turned it back on thinking it would have stopped. NOPE, sound was still on. Had to get to my destination and when I did. I lost some of my hearing. It was that BAD!!

UNKNOWN: I was driving through light to moderate rain. I was following traffic probably at about 35 mph. I was driving in normal mode (no cruise control active) I saw a warning message out of the corner of my eye pop up on my dash (I didn't see what it was because it went away quickly after it came up). Soon after that, a bunch of warning messages started popping up on my dash one after the other. Then my engine shut off (dash still working, sync still working, power steering still working, brakes still working). Luckily, I was able make a turn and then coast into a gas station. Could have been a different story if I was somewhere else. I came to a stop, put it in park, (this is the unfortunate part, I franticly clicked through all the warnings without reading them), then I pressed the start button and turned the truck off. If I was the guess at what I remember seeing, I think I saw messages related to blind spot monitoring and other driver assistance stuff. After about a minute, I turned the truck back on. It turned over fine, but only idled about 20 seconds, and then turned off. Same situation as before except I wasn't moving this time. After calling a few people and a tow truck company (maybe 30 minutes later), I tried one more time to turn on the truck. This time it stayed on and idled normally. I left it on for about 10 minutes and then shut if off. I ended up having it towed because I didn't want to test my luck driving it. It is currently at a Ford dealership being serviced. The latest update that I have received is that the tech ran a diagnostic and could not duplicate the issue.

Speaker Issue: When starting the truck, after about 3 seconds of sitting in the truck, the speakers made a really loud pop noise and then continued to make a loud static noise and cracking noise for the duration of my 15 minute drive home. If this happened on the freeway, it may traumatize someone or cause an accident. The problem has happened twice but it is not been replicable for a dealer or service center. The truck has not been inspected by the manufacturer, police, or insurance reps. I read online that this is happening to a lot of 2021+ F-150s with the B & O Unleashed 18 Speaker sound package. Please recall this, it is the most dangerous speaker issue I have ever heard.

Trailer brake system fault. This fault warning displays when there is a possible lack of trailer brakes. On this vehicle it is on every time the vehicle starts. It began after the recall for the trailer brake module update in June of 2022. It has been to the servicing dealership 4 times and has been there for the past 23 days without resolution. There are many other accounts of this situation on-line also with no resolution.

Audio system malfunction that resulted in deafening random electronic noise levels that would not stop until the battery was disconnected for a long period of time. I started a thread online (link below) and there are numerous others with the issue. There are multiple videos showing the issue. Some have reported a burning smell so there could be a fire risk as well. (https://www.f150gen14.com/forum/threads/dangerous-b-o-sound-system-issue.9254/) It really is loud enough to cause a crash and I believe it's just a matter of time if it hasn't already happened. My ears were ringing for several hours. To date Ford hasn't provided any resolution beyond just extending my factory warranty. The vehicle was taken to the dealer for a full week with no resolution - again, same as several others.

Complaint 1: Mar 14,2022 Manufacturer Recall Number22S12 NHTSA Recall Number22V-142 Parts for recall has not been made available yet, promised for 2nd quarter. We are not into 3rd quarter. How can Ford still produce new trucks if parts are not available to fix existing trucks on the road as it is a safety concern? Complaint 2: Error code P2C44 - requires replacement of Auxiliary Battery Insulator from Ford's internal doc SSM 50976. Was told part is also backed ordered for 45 days. Again how can Ford build new trucks if parts are not available! Please make them fix existing trucks on the road first before new trucks are built! What good are warranties when it takes months to fix.

The contact owns a 2021 Ford F-150. The contact stated that while towing a trailer, he attempted to make a right turn while driving downhill.

The traction control warning light appeared on the instrument panel as the contact began to lose control of the vehicle. The trailer pushed the vehicle off the road and onto a mount of dirt and stone. The trailer damaged the rear bumper and rear right corner panel of the vehicle due to the failure. The contact did not suffer any injuries due to the failure. A police report was not filed since the failure occurred on his property.
