2021 FORD F-150 Complaints

I am reporting a safety-related transmission problem l experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly will shift gears violently, unexpectedly downshifted. This occurred while accelerating, merging onto a highway, turning, crossing an intersection, traveling at highway speed, stop-and-go traffic, 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 NHTSA 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.

For about a year the transmission has been having an issue that has resulted in it now needing to be replaced. Started as periodic hard downshifting between 4th and 3rd gears. Now it periodically up and down shifts hard or skips gears between 2nd and 4th gears.

My truck has spent 80 days in the shop over 11 visits attempting to repair the transmission since 2023. The truck has a hard downshift from 5-4, 4-3, and sometimes 3-1 while light braking coming to a stop. Sometimes it’s several times per day and sometimes not in an entire week. On average it occurs 2-5 times per week. I drive 40 miles to work mostly on the freeway with little traffic with two stop signs going and one stop sign + 4 lights returning so I don’t have that many locations for the condition to be repeated which means the frequency it occurs is pretty high. It is an hard enough downshift where it clunks real bad and sometimes shutters the truck. The transmision cannot last long term and is likely loosening / damaging other components. One of the hardest downshifts I have felt occurred 2 months ago. It shuttered so bad, it felt something could have been damaged. The same day I was holding speed going downhill and it had a hard shift from 3-2. On several occasions in the last 3 years it had a clunk from 5-6 while accelerating on the freeway. Every few weeks it has a hard shift from 4-3 going uphill for power. The adaptive tables have been reset multiple times. Sometimes that helps for a little bit, sometimes not. Long term it is not a solution. The pan was dropped at one of the last visits and a repair made inside. This did not make any significant changes. The hardest downshift I have ever felt (above) occorred several days after this.

I am reporting a safety-related transmission failure I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly failed to engage and then shifted violently, causing an unexpected loss of power and then a change of propulsion. This occurred while merging at highway speed, creating a potentially dangerous situation because the truck did not respond as expected when I needed acceleration. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information for 2021–2022 F-150s identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This 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 issue. Unexpected loss of propulsion while merging, accelerating into traffic, crossing an intersection, or turning could leave a driver unable to accelerate as expected and create a collision hazard. An unexpected downshift or lurch can also abruptly alter vehicle behavior. Because I personally experienced this unexpected transmission event, I request that NHTSA investigate the 10R80 CDF clutch-cylinder/sleeve condition in 2021 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.

*Brake system failure, complete shut down of vehicle. *Vehicle unable to start. *Vehicle was taken directly to Peoria Ford ( 9130 W Bell Rd, Peoria, AZ 85382) via tow truck on XXX Confirmed when dropped off of brake system failure and vehicle not functioning. *Vehicle was inspected on XXX which we were originally told it was the battery. Although the vehicle was in for trailer software recall on XXX and during inspection at that time battery was in good health. *No warnings until attempting to use the vehicle on XXX and received the brake system failure alert. Vehicle would also not lock. *After battery was replaced by Peoria Ford I was then told the brake system would not release and would need Actuator misalignment reset/replaced.

Day Running Lights in headlights fail. The side LED fails completely requiring the entire headlight housing needing to be replaced. This is a common failure and Ford is not doing anything to help the thousands of customers this is affecting. This failure is widely reported online, in forums and chat rooms. Dealer acknowledges it is a part failure but Ford will not pay for replacement even though it is a design or manufacturing problem with this particular year and style of headlights.

Passenger side LED Headlight assembly daytime running LED's, the vertical led has gone out in my 2021 Ford f150, while not a major problem, LED daytime running lights increase visibility of other drivers to help in safety. From research, it seems that many of these headlights, the led daytime running lights in the 2021 year model are failing.

Fuel Pump Failed. Ford has stopped sale on the Fuel Pump because of recall 25S75. I need a fuel pump to operate my vehicle. Ford has offered no solution. It has been 10+ months since my fuel pump failed. Why is there no urgency? What am I supposed to do? Ford doesn't care, you at NHTSA don't care.
