2021 Ford F-150 Hybrid brakes problems

Filed Oct 17, 2026 · Brakes · OK

I was driving home after dark from a work trip. I was about 15 minutes from home when I slammed on my brakes to avoid hitting a deer that ran out in front of me. I was going approximately 45 miles an hour. Then all of the brake warning lights and ABS Fault lights came on. I was able to get home with no problem and though it might have just been because of the sudden brake application and it would clear at the next drive. When I went to drive my truck next, I had no brakes and the pedal went to the floor. I started looking and found a puddle of brake fluid under my truck. I used to be a mechanic, so I started to trouble shoot the problem and found that a wire mesh covered flexible section of the brake line feeding the front passenger wheel brake caliper had a blow out and is what had failed. Although my 2021 F-150 is out of warranty, a 5 year old well maintained truck shouldn't have a brake line fail and I think I was luck to get home safe. I had my truck towed to the local Ford dealership for the repair. They did a thorough examination and could find a reason for the failure and agreed that it shouldn't have failed and that they had never seen anything like it before.

If you pull onto a road and try to accelerate, the vehicle is unresponsive. The RPMs will increase, yet the vehicle drive train (10 Speed Transmission) is unresponsive for several seconds. This has been an ongoing issue with the vehicle since new and was first reported to Ford Customer service on Jan 2022. Ford has made several attempts to fix this issue, yet the transmission continues to fail with the same issue. This is a critical safety issue that jeopardizes the passengers in the vehicle. Vehicle parking brake engages without notice. At any given time, the electronic parking brake engages without warning and you have to manually release. While sitting at a controlled intersection, on an inclined street, waiting for traffic light to change, with vehicle in Drive, foot on the brake, the electric parking brake engaged. Vehicle shift lever moved to the park position on its own. Vehicle engages it's parking brake and moves shift lever into Park while sitting in traffic is very dangerous. Vehicle shift column failed in drive and vehicle would not move or run. This caused drive train to lock in place, freezing all four tires. Ford had to drag truck onto flat bed with tires locked. It had to be dragged off flatbed when delivered to Ford dealer for repair. They had to put grease down on the flatbed so truck would slide off without tires rolling. While at the dealership, the mechanic had to manually disconnect the calipers in order to move vehicle. The safety backup features failed and would not release wheels (lever under steering column).

On November 29, 2023 I took my 2021 F150 to Larry Miller Ford for servicing and repairs related to Recalls 22S71 and 23S35. When the tech was rotating the wheels he discovered that the axle shaft bolts were sheered off on both the left and right rear wheels. The service manager called to tell me that this was a serious safety issue and that only the brake rotors were preventing the wheels from falling off the truck. The service manager told me there was a "Customer Satisfaction Program 22B34" issued by Ford, but no Ford Recall relating to the problem. Larry Miller Ford has replaced both axles and axle bolts. I am waiting to find out if there is damage to the rotors, calipers or brake pads, a concern since the sheered off bolts were rattling around within that area since breaking off apparently between service visits. I strongly believe Ford should be required to issue a recall on this problem. I never received a notification on CSP 22B34. Had it not been for my tire rotation, the wheels could have fallen off at highway speed.

Electronic parking brake activated unexpectedly at low speed after taking off from a stop. From a stop traveling downhill at a low rate of speed, the parking break activated and caused the truck to skid to a halt three times causing a safety issue for drivers around the vehicle. Manually deactivated the electronic parking brake each time and after forward movement at about 5 mph, it activated again. After the fourth attempt to start forward movement, the electronic parking brake stayed off. After doing research, recall 23V‑509 came up but this specific VIN does not appear to be tagged under that recall.

This is the 4th time since purchasing the truck that this event has happened with time having the most severe results. When shifting from reverse to park the shifter goes into park and jumps back into reverse. First event (after exiting the truck) the truck rolled into a shipping dock breaking a taillight and buckling the rear bumper. Next two I had one foot on running board and one foot in the truck ant was able to hit the brake stopping the truck. This fourth event one foot was on the running board and one on the ground. As truck went back the door flattened me to the ground and the front tires rolled over both of my legs. The truck rolled up an inclined parking lot, across a busy road and down a bank. I was driven by ambulance to the hospital and then transferred and airlifted to trauma center at Ruby Memorial Hospital. After the second event the local Ford dealer said they could not duplicate the event. The brakes do not hold even though they are depressed and set when the shifter is shifted.

My trucks integrated brake controller will not consistently control the electric trailer brakes. I plug in the trailer and get confirmation that it is controlling the brakes by manually testing them while rolling and at some point during the trip it stops controlling them without warning. I have tried all methods to be sure the 7 pin connection is seated properly and I am sure it is. I have a 7 pin tester and when I check the electric output at the plug it lights up the circuit (BK) for the brakes. When traveling and I realize I no longer can control the trailer brakes, I pull over and unplug the trailer, plug in the tester and when squeezing the brake controller it will not light up the circuit marked (BK). If I leave it disconnected and shutoff the truck for 15+ minutes and reconnect, it works again only to stop again at some unknown point. There is obviously a seriously dangerous issue here. I have taken it to the Ford dealer and they can't find anything wrong. When it resets you can't duplicate it until you tow for an undermined distance for it to fail again. I have searched the internet and found many people with the same issue and no one has been able to get it solved by all manner of efforts including many efforts at Ford dealers and electrical shops. This form asks for the date it occurred. It started as soon as I took delivery with 5 miles and is ongoing.
