2021 Ford Mustang: hesitation when accelerating

Filed Jun 22, 2026 · Fuel system · NJ

My vehicle, VIN [XXX], is subject to the federal safety agency Recall 25V455 (Ford Recall 25S75) involving a defective low-pressure fuel pump that may cause engine hesitation, loss of power, or engine stalling. This recall was announced in July 2025 and remains open on the federal safety agency VIN lookup as of June 2026. More than eleven months have passed since the recall was announced, and Ford has not provided a repair remedy for my vehicle. I believe this is an unreasonable delay for a safety-related defect. In addition, the recall previously appeared in the FordPass application associated with my vehicle but no longer appears there, even though both the federal safety agency and Ford recall website VIN lookup continues to show the recall as open. This discrepancy creates confusion regarding the status of the recall and whether Ford is actively notifying affected owners. I am concerned that my vehicle remains subject to a known safety defect without an available repair and request that the federal safety agency review Ford’s handling of Recall 25V455, the prolonged delay in providing a remedy, and the inconsistency between Ford’s customer-facing systems and the federal safety agency recall database.

At idle the engine idles roughly and rotates randomly at speeds from 300 to 900 RPM. When starting from a stop such as a traffic light or when pulling onto a roadway hesitation is often noted and on several occasions this has resulted in near accidents as the vehicle won't proceed as required to move through an intersection.

1st dealer visit: at low speeds car acted like it was in neutral and then surged when trying to accelerate. Dealer said they corrected the issue. they did not. 2nd dealer visit: car was still doing the same as number 1. While on the highway with cruise control set at 75 mph, I lost power and smoke started billowing from under the car. transmission was shifting erratically, went into limp mode and i made it off the highway to call a tow truck. Dealer said they repaired the issue. 3rd dealer visit: car is still doing the same as number 1. now the car is also very jerky in 3, 5, 8 gears. I almost ran into my own car while parking due to the random lunging. It hesitates and stumbles in most gears and I have no confidence when pulling out onto a street or trying to pass on the highway. It shifts extremely hard from 4th to 5th gear; feels like I ran over something or got rear ended. The dealer wants to repeat the same repair they tried in visit #2, new valve body. -Transmission failed. dealership says valve body but the new one is broken also. waiting on the 3rd one for this car. Possibly available for inspection; it is at dealership. -Random lurching at low speeds and power loss on the highway are my safety concerns. -Dealer found the issue and attempted repair. -Manufacturer, police or insurance have not inspected. I have a ticket open with Ford currently. -Warning lamps? not on the 1st visit. yes, when I lost power on the highway but the light came on well after the issue was apparent with smoke behind me. 3rd visit, no warning lamps.
