2021 Ford Expedition Complaints

My Ford Expedition’s 10-speed automatic transmission experienced repeated slipping and sudden loss of propulsion. While accelerating from a stop and entering the highway, typically around 15–20 MPH, the engine would suddenly rev but the vehicle would stop accelerating, as if the transmission had shifted into neutral. I had to release the accelerator for several seconds and slowly reapply throttle before the transmission would re-engage. This occurred repeatedly and created a serious safety hazard when pulling into or crossing traffic because the vehicle could begin accelerating normally and then unexpectedly lose propulsion with approaching traffic. The transmission also exhibited severe harsh/banging shifts during harder acceleration and produced a rattling noise while slipping until the accelerator was released. CDF drum failure has been confirmed. The vehicle is currently at a reputable independent transmission repair facility undergoing a transmission rebuild due to the CDF failu...

The contact owns a 2021 Ford Expedition. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however the vehicle failed to accelerate as intended. The contact noticed an abnormal sound and the vehicle jerked. No warning lights were illuminated. The failure was persistent. The vehicle was taken to the dealer and to an independent mechanic; however the failure could not be duplicated. The vehicle was not diagnosed or repaired. The contact stated that the vehicle was the family's only means of transportation, and the vehicle was unsafe to drive. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was unknown.

For the past three years I have complained about the transmission dropping out of gear. It happens most often if I'm towing a trailer. I seems to occur in spurts, happening a couple of times in a few days then not for some time. Very dangerous if you pull around to pass and suddenly you lose power. Originally the dealership said they could find nothing wrong. I have read recently that Ford is having trouble with their transmissions. At my latest service appointment, I restated my problem and was told I need a new transmission.

While stopped at a traffic light, my 2021 Ford Expedition began running rough. When the light changed and I accelerated through the intersection, the vehicle experienced a severe loss of engine power and barely made it through the intersection. After I pulled off the roadway and released the accelerator, the engine stalled. I was able to restart the engine once while applying approximately one-quarter throttle. It continued running rough and stalled again when I released the accelerator. The vehicle was taken to Robinson Brothers Ford/Lincoln in Baton Rouge, Louisiana. The Ford dealer documented the rough running, low power and stalling and diagnosed the "fuel pump inop." The dealer removed the fuel tank and replaced the fuel pump/sender assembly. The replacement part listed on the dealer invoice is Ford part JL1Z-9H307-G. Vehicle mileage was approximately 79,390. Several months before the complete failure, during very cold weather, I also experienced one brief incident of unusually...

Vehicles automatic transmission repeatedly looses its gear, often while accelerating. The transmission tries to shift down, but somehow ends up loosing engagement and will not re-engage. This lead to critical/dangerous situations on Highways due to the sudden loss of power.
