2021 FORD EXPEDITION Complaints

Fuel pump part number JL1Z*9H307*G failed at highway speed leaving vehicle stranded in express traffic lanes. But for the prompt response from FHP this would have resulted in a serious crash. The vehicle has almost never been operated below 30% of fuel capacity and has never been operated to near empty fuel. There are no known wear or accidents that impact the fuel system. there were no warnings or other symptoms prior to the complete pump failure.

The contact owns a 2021 Ford Expedition. The contact stated while driving approximately 70 MPH, the vehicle experienced a loss of motive power. There was no warning light illuminated. The contact stated that while attempting to pull over to the shoulder of the roadway, the vehicle regained motive power independently. The local dealer was contacted and referred the contact to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The contact related the failure to a fuel system recall that had not included the model year of the vehicle. The manufacturer was notified of the failure and a case was filed. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 53,000.

Fuel pump failed in express lane, unable to move the vehicle from travel lane under its own power.

Transmission has completely failed at 68,000 miles and 4 years old. Ford is willing to cover cost of the tramission with a “partial good faith” agreement but the dealership who provides the service is charging $5,656 to put in new transmission. This is a widely known transmission problem with safety issues with multiple service bulletins. They are passing the issue onto the consumer instead of recalling. Shameful.

The contact owns a 2021 Ford Expedition. The contact stated that while his wife was inside the vehicle with the vehicle idling, the vehicle vibrated and then turned off. The contact's wife attempted to restart the vehicle, but the vehicle failed to start. The vehicle was towed to the dealer, where it was diagnosed, and the dealer retrieved DTC: P0627; and informed the contact that the fuel pump had failed. The control unit and fuel pump were replaced. The contact referenced NHTSA Campaign Number: 25V455000 (Fuel System, Gasoline); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 74,000.

This vehicle continues to exhibit transmission shuddering, slipping, and hesitation during acceleration—despite two full transmission replacements in two years and multiple dealership service visits. These unresolved issues compromise safe operation, especially during highway merging, rapid acceleration, and lane changes. Both dealerships were unable to permanently address the issue after extensive mechanical intervention. Ford has issued multiple Technical Service Bulletins addressing transmission concerns in the 10R80 unit used in the Expedition. The most recent bulletin, TSB 25-2132, revises procedures for harsh and delayed shifting, shudder, and internal hydraulic leakage tied to the CDF clutch drum—which aligns directly with the findings from my own transmission overhaul documented in June 2023. Previous service entries noted suspected internal leakage around the CDF clutch, RPM flare during shifts, gear hesitation, and recurring drivability issues despite component replacement. These match symptoms targeted in prior TSBs, including: TSB 23-2123: Harsh engagement and shift delays TSB 24-2101: Hydraulic leakage diagnosis linked to clutch cylinder TSB 25-2023: Update to inspection and service steps for gear shift quality While dealerships performed repairs and even full transmission replacements, the lack of lasting resolution and repeat issues reflect a broader mechanical defect addressed reactively rather than proactively through these bulletins. Despite awareness at the manufacturer level, I experienced significant delays, financial burden, and ongoing drivability risks. I respectfully request that NHTSA further investigate Ford’s handling of repeated 10R80 transmission failures in the Expedition, particularly concerning the effectiveness of these bulletins in preventing recurrence and mitigating safety impact

The contact owns a 2021 Ford Expedition. The contact stated that upon attempting to accelerate from a stop, the vehicle started to shake abnormally, and lost motive power. The check engine warning light illuminated, and the contact immediately attempted to restart the vehicle; however, the vehicle failed to start. The vehicle was towed to a local independent mechanic where it was diagnosed, and the contact was advised that the fuel pump was faulty and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 95,000.

The contact owns a 2021 Ford Expedition. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The contact's wife had attempted to start the vehicle several times. The contact stated that when the vehicle was started, the accelerator pedal was depressed, and the check engine warning light illuminated. In addition, the engine seized. The vehicle was towed to the dealer where it was diagnosed with fuel pump failure. The contact was informed that the fuel pump needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and a case was filed. The contact referenced NHTSA Campaign Number: 25V455000 (Fuel System, Gasoline); however, the VIN was not included in the recall. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 71,000.

Transmission Failure Rough or jerky shifting: This occurs when accelerating or decelerating, and even when shifting between gears. Delayed gear engagement: Shifting from park to drive or reverse can be slow, or the vehicle may lunge into gear. Transmission slipping: The transmission slips between gears, causing a loss of power or acceleration. It can also cause a violent grinding/shaking between shifting gearshifts resulting in loss of acceleration.

The transmission shifts gears irregularly and has loss complete power when going up hill. This is a known issue with the 10 speed transmission but Ford has not corrected the issue that is impacting thousand of vehicles. This issue with the shifting happens everyday that I drive it.
