I am the owner of a 2021 Lincoln Navigator black label, currently subject to Safety Recall 25S75 concerning the low-pressure fuel pump that can cause engine stalling and increased crash risk. Ford’s recall filing and public reports make clear the hazard and that a remedy is still being developed. My vehicle has repeatedly exhibited hesitation and loss of acceleration consistent with the recall since I purchased the car in 2021. While driving on the highway with my 10 year old daughter and her friend home from soccer on 495 last Monday 9/29, I tried to pass a car by switching to the left lane and stepped on the accelerator. The car hesitated, and felt like it was going to cease altogether for a moment, however the accelerator did finally « catch » and I was able to pass the car. I have had this same sensation while pressing my foot on the accelerator though at low speeds on backroads. After the incident last Monday I had the car towed to the Lincoln dealer so they could assess the car. I have been told that the oil was very low. The oil light or check engine light was never on, and it has gone on previously when I’ve been due for an oil change. I’ve been told that the tires also need to be rotated. The dealer who serviced the car said that the car is driving great now and is safe to drive and can be delivered to me or I can pick up. I called Lincoln corporate Friday 10/3/25 and a case was opened and called back on Monday and spoke with a representative who said that there was nothing she could do if the dealer is saying that the car is safe to drive. I don’t feel safe driving the car with this open safety defect unrepaired. A loaner to use while the process for repurchase of the car would be appreciated, but is being denied while they continue the process of good faith eval /consideration of repurchase of the car.
