2014 FORD F-150 Complaints

while driving my vehicle it suddenly downshifts from 6th gear to 1st gear causing the rear wheels to lock up.

Lost brakes at the same time the low Brake Fuid warning light came on. Was able to slow down by shifting the automatic transmission into a lower gear and using the Emergency Brake. The the fluid in the Brake Fluid reservoir was empty. I refilled the Brake Fluid reservoir up to the full line. It Brake warning light was off so I decided to try to make it back home. About 2 uses of the brakes and they failed completely again as I used the same method of stopping the truck as I did before when I found a safe place to get off the road. After having it towed to my house I pulled the Master Cylinder off the Brake Booster and the Booster was full of Brake Fluid. The rear seal of the Master Cylinder had completely failed. The issue is the same issue as on the other 2 recalls on 2014 Ford F150 Ecoboost and the other 2014 Ford F150 with the rear seal on the Brake Master Cylinder failing which allows the Brake Fluid to be pumped into the Brake Booster instead of the Brake Calipers. If they used the same Brake Master Cylinder on the 5.0 Liter F150 as they did on the recalled F150s, then they need to recall these also.

Vehicle was on & operating for 20 minutes and after traveling 1-2 miles all of the sudden smoke came from engine compartment. Pulled over immediately, and turned vehicle off when a full fledged fire began in the engine block on passenger side. Ran into gas station and used a fire extinguisher to get fire under control. 911/Fire Dept was contacted and hosed down hood, engine compartment. Analysis showed the source of the fire was from the passenger side hood accent light (factory installed) short circuited and was the origin of the fire.

We received a low brake fluid light on the dash. I verified the low level was legit by inspecting the brake fluid reservoir, which was indeed empty. I filled the reservoir with DOT 4, I drove approximately 2 miles, and received the low level brake fluid alarm again. I drove approximately 17 miles until I could get more DOT 4, during this 17 miles I used the trailer brakes to stop as I had no Ford F-150 braking. I filled the reservoir with more DOT 4 and drove 2.5 hours home, with the low fluid level alarm in due my master cylinder and booster continuously leaking… the truck got turned in the Bill Brandt Ford where they found a leaking master cylinder and broken booster.

Brakes failed after I had driven and parked the truck. Brakes worked normal. Cranked up and went to drive away and brake warning light illuminates. Applied brakes and pedal goes to the floor. Opened hood, Master cylinder empty. It’s looks like the Brake Master cylinder suddenly failed. Luckily it happened when I was starting off.

When driving on the highway going about 50 mph, my speedometer dropped to zero, back up to 35, back to 10, then back to 50 and the truck violently downshifted into 2nd gear, back to 4th, back to 2nd and then back to 5th. It happed again this morning going about 30 mph. It dropped to about 15, back to 25, down to 15, hard shift and the back to 35mph. I have a short video of it happening but can't attach.

On 6-20-2021 the brakes failed on my 2014 Ford F150 3.5 V6 Ecoboost engine almost causing an accident. I found two recall notices but my VIN number was not listed. I took the vehicle to Ford in Livermore, CA and had it repaired. I then contacted Ford and I have a case number. I then went through all my maintenance history and found that there was actually a recall in 2017 with my VIN number. Apparently I did take the vehicle in and it was repaired. The recall was then deleted on my truck because it was repaired. Now in 2021 the same problem happened again. A master cylinder is a pretty simple part and should not fail this often. I will follow up on this with Ford.....

there are two safety recalls on 2014 Ford F150 brake master cylinder failures. My VIN is not on the recall list but I have the exact same problem as they have. My brakes failed and I almost ran into a cross street with traffic. I have the vehicle in the shop now and they say if I am not on their recall list they can not help. My vehicle is the same year, same model, same engine etc. so I am confused. This is definetely a safety concern. Will be interesting how many other vehicles like mine have the same problem.o

The contact owns a 2014 Ford F-150. The contact stated that the brakes failed. When the contact attempted to move the vehicle out of the park position the brake pedal failed to engage, the brake pedal became hard to move. The contact stated that the vehicle had to be moved by reversing the vehicle. The vehicle was towed to the dealer. The dealer performed a diagnostic that located the failure code at the brake booster and the master cylinder. The vehicle was not repaired. The manufacturer advised that the vehicle was not included in NHTSA Campaign Number: 20v332000 (service brakes hydraulic). The failure mileage was 83,000.

while driving on the freeway my 2014 ford f150 suddenly downshifted from 6th gear to 1st gear causing my rear wheels to lock up and having the steering wheel jerk to the left. the car behind me had to swerve to avoid hitting me from behind since the trucks wheels locked up with no brake lights. this has been the 8th time this has happened. each time i take it to ford for them to check it out they tell me they can not duplicate the issue. the wrench light comes on and it throws codes and ford will do nothing to fix it.
