The same brake booster that allegedly only had 51 vehicles included in it? Same exact issue as this link: [XXX] not working seems like a pretty big safety issue.

I was traveling 47 mph and suddenly the parking brake was activated, causing the car to brake instantly. Luckily, no one was behind me and luckily it did not cause an accident. There were no lights on the dashboard. I took it to the Ford dealer to have it inspected and they gave me an appointment for 8 days later and let me go home knowing that I could not drive it since I almost caused an accident.

I was slowing to a stop at a stoplight in traffic when the brake pedal dropped to the floor and the truck was no longer slowing. The ABS, Anti collision, and check brake system lights all illuminated. I was able to slow the truck and place in park to stop. Vehicle was taken to dealership where it was found to be in perfect condition according to the mechanic. I have been told that I should have no issue taking the vehicle although nothing has been resolved.

Purchased vehicle w/ roughly 5000miles in 2021 from Ford Dealer. All stock items and factory tires. At roughly 50,000 during state inspection, it was found that the front passenger brake line was chafing on tire and was deemed unsafe by the Ford dealership. No prior work or modifications was done in this area. Research indicates that this is happening to other Ford F150s

On Wednesday [XXX]. The front brake hose rubbed against the right front tire, causing it to bust and me to lose brakes very dangerous, difficult to stop my vehicle. This needs to be addressed. All the brake safety features failed and all the brake related dash lights came on. The truck is at Bob Bell Ford in Maryland.

While driving the parking break activated. I was in the middle of the road with my newborn. I believe my truck should have been recalled since this is something that other F150 had. I took it to the Ford dealership and they said there was no active recall on this vehicle. So I had them check it since it-??s such a high safety concern. And yes there was a default with the parking break system.

I contacted a local Ford dealership: Hempstead Ford, 301 N Franklin St, Hempstead, NY 11550, (516) 363-1579 to perform multiple safety recalls issued by NHTSA. The service department refused to schedule me for service because I did not buy the vehicle from their dealership. I reported this to Ford Customer Relations and was told that they cannot force the dealership to service my vehicle. I believe this is illegal.

Truck was repair as per the recall of the emergency brake however is still applying the parking brake again and took it to have it scan but ford dealer ship says they don't find no codes or anything saying it does and I'm just scared of continuing to put myself and my family at risk when is still applying the emergency brake whenever it wants. So far has done it over 3 times in a period of a few moths after the recall was supposedly been done for that same reason. On the picture I'm posting here is the invoice of the repair of the recall. Is in Spanish part of it but all the numbers of the recall are there

While approaching a red traffic signal at speed, I went to apply brakes and the brake pedal had no resistance and failed to slow the vehicle. Immediately several alarms sounded and lights illuminated on the dash board. I was able to slow the vehicle with repeated brake attempts and swiftly moving to the right turn lane where I could navigate a turn and come to a complete stop after coasting. Dashboard indicated: Pre-collision assist not available, antilock brake fault, service AdvanceTrac, and check brake system.

Unknown which component is failing. It started with a rumble while accelerating or coasting but goes away when I shift into neutral so I believe that is the transmission. Other issues that are occurring randomly, speedometer will change indication to slower speed than I am actually going or it will drop to 0 while I am driving. Alerts and faults that have shown at the same time the speedometer goes out are: Powertrain fault, ABS, Forward Collision Warning, Parking Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Blind Spot Warning, Lane Keeping Assistance, Cross Traffic Warning. Also a random metallic spinning noise coming from under the truck. It has been in the dealer garage 5 times now.

My family and I were driving to a local coffee shop when my dash went off with a low brake fluid warning, I pull over to check and it was bone dry. That pretty odd so I immediately start looking for leaks and discovered the passenger side rear brake line where it connects to the rubber hose and goes to the caliper has a MAJOR leak. I videoed the leak so show how bad it was and where it was leaking from. The rubber hose itself if fine the leak is coming from the metal part of the hose but unfortunately the way to fix the issue is by replacing the hose assembly and according to ford that part is a wearable item, so my extended warranty I paid for it does not cover it. I find it absurd and extremely dangerous that a three-year-old truck has a major brake fluid leak like that and Ford has been no help at all. I-??ve spent all day on the phone with them arguing and they don-??t seem to care. This is a major safety issue from a clearly faulty part from the manufacturer, and I don-??t feel as though I should be responsible with the bill.

While driving forward the parking brake system automatically applied itself. Because of this I was nearly involved in a rear end collision. This was completely unexpected and without warning. The vehicle was in for service last week. It is now back in service and they are having trouble diagnosing the parking brake system. My vehicle is currently at the dealer and the dealer is in contact with Ford because the dealer is having trouble diagnosing the parking brake system.

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.
