I've experienced the loss of power during hard acceleration. Right hand turns from a stop feel like the engine has stalled and rolling right hand turns are becoming increasingly more dangerous. Most recently as I was merging onto a highway. Pedal to the floor, the truck initi9ally accelerated for a couple seconds until it stalled to make the truck not only not accelerate but almost made it feel as if I was breaking. This is very dangerous.

Cruising highway speeds, when accelerator is pressed to gain speed, make a pass, ect the transmission downshifts into 3rd gear, engine losses all power for 4-8 seconds while accelerator is held down. I-??ve almost been in several accidents due to expecting a vehicle to accelerate and nothing happening and traffic

The truck is a 10-speed and the 10 gears are displayed on the dash. While driving down the road, the gears start to disappear. Once it gets to the gear you are in, it will force a hard downshift. It will continue to force a downshift into first gear and the truck stops with hard engine breaking. The first time (6/26/2024), I was almost rear ended. If you put the truck into neutral, all gears reappear and you can start to drive again without any indication of transmission issues until the gears start to disappear. Ford dealership has attempted to fix multiple times, but continues to happen. If not expecting, is very sudden and can cause rear-end collision or loss of control. I have a detailed record of the incidents (date, speed, mileage, etc.) as well as multiple videos demonstrating the issue. Not able to upload videos.

Rear axle seal busted because the rear axle hub bolt broke. Dealer indicated this cause the axle boot to bust allowing water into the differential. Dealer stated parts for recall aren't available and/or are on national back order. Ford estimates a fix will be in place 1st quarter 2025. So I am out of a vehicle until this time. Ford refuses to cover a rental.

Check engine light on. Ford says exhaust heat exchanger bypass valve. I see online multiple people are having the same issue. Seems to be a common issue with this vehicle. They are saying it-??s not a part of the power train warranty although it-??s attached to the power train. This is a safety issue. With the amount of posts about this issue I-??m surprised it isn-??t a recall already.

I started to pass a vehicle, when I tried to accelerate the vehicle lost all forward momentum like it was in neutral, I pressed the gas to the floor and then engine did not raise the rpm-??s and no forward increase in momentum, I then let off the gas, and then reapplied full gas and it very slowly started to move forward again. This almost caused an accident as I was passing on a 2 lane road over a broken yellow line, it just fell flat on its face.

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.

While operating the vehicle, I shifted into park, using the console shifter. With no warning, the vehicle malfunctioned. The console shifter indicator light started blinking next to the "P" and it would not let me shift back into gear. I turned off the vehicle and tried to restart it in the hopes that it would clear the error. The vehicle engine would not start, and told me to shift the vehicle into park. I was unable to shift the gear into park or any gear. A tow truck driver came and we were able to force the vehicle into neutral for towing, but the vehicle's parking brake engaged and would not disengage. Every time we turned off the parking brake, it immediately turned itself back on. Thus, we could not push the vehicle into a better position for the tow truck to get the vehicle and the tow truck operator had to drag the vehicle with its back tires not turning. At the Ford dealership, a service employee inspected the vehicle and said there was no physical damage to any component and that some kind of electronics error had caused the fault. He said it was a known issue with F150 transmissions and that a Ford service bulletin indicated a 6-hour "module" reprogramming process was necessary to make the truck operable. He said that it could recur. I spoke to Ford customer service. A representative there confirmed that this is a known issue with F150 transmissions but that no recall had been made. She also stated that Ford did not know why it happens and that, even after being "reprogrammed", it could happen again. Based on my experience and discussions with Ford, the F150 can suddenly become inoperable and (because of the parking brake) immovable. Thankfully, the transmission error occurred for me in a safe location near my home. It could have been very dangerous had the vehicle become immovable in an unsafe location or far from home or help. I am concerned it will happen again. The vehicle is currently at the Ford dealership in Grand Ledge, MI.

The automatic 10 speed transmission 10R80 covered by TSB24-2176 will violently downshift or upshift causing passengers and contents of the vehicle to be thrown around the vehicle. This happens at random events, sometimes while accelerating, sometimes while decelerating, and without warning, which leads to violent decelerating and lurching on the road, which is a safety concern in heavy traffic. The transmission has been serviced 3 times by Ford of Homewood, twice under warranty and once out of warranty (60K powertrain) but there is no fix or remedy to repair this issue. I own several other identical 10 speed equipped trucks that operate fine, perhaps a bit jerky with shifting, but this truck is a safety hazard that cannot be repaired.

At a stop, in electric mode, truck will lunge forward as if you were rear ended. Most of the time, transmission failure will occur after some time due to this lunging forward, and it has happened to many truck owners. Electric auxiliary transmission pump tends to be the cause.

Good day, I am experiencing a leak from the front differential pinion seal on my vehicle. This leak appears to be a common issue based on reports from other owners in various online forums and owner groups. The front differential transfers power from the transmission to the front wheels. A leak from the pinion seal can cause a loss of differential fluid, which could lead to premature wear and eventual failure of the front differential components. If the front differential fails while driving, it could cause a loss of control of the vehicle and increase the risk of a crash or collision. This poses a significant safety hazard to myself, my passengers, and other vehicles on the road. I am requesting that Ford Motor Company acknowledge this issue and take corrective action by issuing a recall or service bulletin to inspect and repair/replace the faulty front differential pinion seals on affected vehicles. Allowing this defect to persist is unacceptable from a quality and safety standpoint. A front differential failure caused by this leak could result in serious vehicle damage, injuries, or fatalities. Please investigate this matter thoroughly and require Ford to address this safety defect before it leads to additional vehicle failures and potential accidents. Thank you!

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.
