While traveling home on a 2 lane highway 55 on a busy Sunday, the truck started misfiring and jerking, shaking then stalled. Engine light was flashing and we were able to pull off to side as it stalled. After a short time we proceeded on the highway, as we were in a precarious position, about 3 miles and it began misfiring and stalled again. This could have been a tragic situation had there not been a pullout with our travel trailer. We had to have our truck towed to the ford dealer and our RV towed home. While seeking similar cases online we believe it to be a fuel pump driver module and contamination. Our truck VIN is not currently on the national recall list and feel it should be.

I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly has lost propulsion and RPMs flare while driving steadily uphill. This occurred while merging onto a fast moving highway and while traveling at a steady speed going uphill, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that the federal safety agency investigate the 10R80 CDF clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed.

I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly shifts hard/lags on gears 3-5 and sometime higher gears 7-9 at higher speeds. I’ve also noticed a buzzing/metallic rattling coming near the engine from inside. There is also times i can tell i have no power when trying to speed up and the other day i almost thought i was going to get T-Boned.

I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly slipped at least twice, and shifts violently often. The truck while driving on a 35mph road after just going over a railroad track I went to accelerate and lost gear and the transmission slipped really bad and violently caught a gear after reaching around 4000 rpm. The truck also shifts violently when under moderate acceleration at almost all times in gears 2-5 creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion.

I'm reporting a transmission problem on my 2021 Ford F-150 with the 10R80 automatic transmission that I believe is a safety issue, not just a reliability one. The truck currently has about 55,000 miles on it. Right now the truck shifts hard and jerks every time I drive it, and it's especially bad at low speed. The worst situation is creeping through a parking lot looking for a spot, the transmission drops down into first with a clunk and a jerk, and then kicks again when it shifts back up out of first. It's rough enough that I've taken to putting the truck in "Eco" drive mode on purpose, because that softens the shift profile and takes a little of the edge off. Once I'm out of the low-speed stop-and-go and up to normal road speed, it seems to smooth out and drive okay, but the low-speed shifting is genuinely excessively rough. From what I've read, this matches the known 10R80 problem where the CDF clutch sleeve can move axially and cause hydraulic-circuit leaks, which leads to slipping, RPM flares, delayed or harsh engagement, and unexpected shifts. Everything I've found says this condition progressively worsens as the transmission degrades. That's exactly why I'm filing now rather than waiting. A hard, unpredictable shift or a loss of propulsion at the wrong moment — pulling into traffic, crossing an intersection, merging — can easily cause a collision. I don't want to wait until it fails in a dangerous spot and someone in my family gets hurt. I'd like the federal safety agency to investigate the 10R80 CDF clutch-cylinder/sleeve condition on Ford F-150s and to review Ford's warranty claims, dealer repair records, transmission replacements, and other owner complaints to determine whether this is a defect requiring a recall. Owners shouldn't have to wait for a dangerous failure before a known condition like this is addressed.

Jerking when accelerating and shifting, when this occurs vehicle has a harsh movement forward then there is a delayed response when trying to accelerate have been multiple occasions where I go to make a turn and vehicle doesn’t respond or stopping in the middle of a turn almost causing my vehicle to be tboned

After coming to a complete stop the truck violently lurch’s forward. To the point that it feels as if another vehicle has contacted the rear of the vehicle. This seems to be attributed to an auxiliary pump failure.

The contact owns a 2021 Ford F-150. The contact stated while attempting to make a turn from a complete stop at an intersection, the accelerator pedal was depressed but the vehicle failed to respond. The contact stated that the START/STOP feature was engaged at the time of the failure. The contact turned off and restarted the vehicle several times and the vehicle responded. There was no warning light illuminated. Additionally, the contact stated while driving in a construction zone with the Lane Departure Steering Assist mode engaged, he turned the steering wheel to avoid the construction cone; however, the vehicle veered to the opposite direction and was pulling towards the construction cone. The contact also stated while driving and passing a semi-truck, the vehicle jerked and was pulling to the right, towards the rear of the semi-truck. There was no warning light illuminated. Additionally, the contact stated while driving at an undisclosed speed, the vehicle pulled toward an embankment. The contact deactivated the Lane Assist feature. The contact stated while driving and depressing the brake pedal to make a complete stop, the vehicle failed to respond. The contact stood on the brake pedal, but the vehicle hesitated to respond, causing a 10-foot stopping distance delay. The vehicle was taken to the dealer where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the dealer. The failure mileage was approximately 9,000.

While traveling at around 70 mph, the truck felt like it losing power. As I further step on the accelerator, the truck didn't response. The truck then jerked and shifted to gear 9 and jerk again then shifted back to gear 10. This happen for about 10 to 15 minutes and back to normal. During this time the truck loss the ability to accelerate. This happen during the cruise control engaged and also happen without the cruise control engaged. When this happen, the truck had about 35,000 miles and it happened during a road trip from Southern California to Flagstaff, AZ. The problem also happened on the way home. The problem was not observed as the truck travel at 65 mph or less.

My 2021 Powerboost F-150s experienced an issue where the truck lurched forward as if hit from behind after coming to a stop. This can result in the truck hitting the vehicle in front of you if you are in tight traffic. I dropped the truck at the local Ford dealer and was told it will take 1 to 3 months to fix the vehicle due to part in back order.

Vehicle lurches forward when transmission is in drive position, when stopped with foot on the brake. It is very forceful and feels like being hit from behind. It could easily cause a collision with a car stopped in front of my vehicle.
