Lincoln Navigator fuel pump problems

Filed May 9, 2026 · Driver assistance, Fuel system · WA

Vehicle is subject to multiple open federal safety recalls with no repair remedy currently available from Ford/Lincoln. One recall involves potential fuel pump failure causing loss of fuel pressure, engine stall while driving, and increased crash risk. A second recall involves interruption of driver assistance and visibility systems including rearview camera, forward collision warning, lane keeping, and related safety systems. This vehicle is operated in a commercial passenger rental fleet. Due to federal rental vehicle recall compliance requirements, the vehicle was removed from rental service immediately after issuance of the recalls and cannot legally be rented until repaired. Ford/Lincoln currently has no available repair remedy despite the recalls having been active for an extended period of time. The lack of available remedy has rendered the vehicle commercially unusable for an extended period while continuing to create ongoing safety concerns related to engine stall and interruption of critical driver assistance systems. The vehicle remains unavailable for lawful commercial operation pending manufacturer remedy.

problem is when you go to check the oil do you think you’re gonna find a low oil situation and what happens is the oil is actually overfilled however it’s not overfilled because you put too much oil in it. It’s overfilled because gasoline is leaking into the oil pan. So the oil is diluted and it actually doesn’t even seem like oil. It seems like dirty gas. That’s how much gas gets into it. Supposedly this is a known issue after searching it on the Internet, this is known, and it happens with this making my vehicle. The manufacturer should be responsible for fixing it. Supposedly the fix is either changing the fuel pump or fixing the valves or maybe a combination of both either way the consumer should not be stuck with this. This is a design error or defect. It says there’s also a problem with the gasket I feel I should not have to pay to get this fixed. This is a designed defect and they sold the car this way knowing afterwards that there’s an issue with it. My crank case is filled with gas when I pull the dipstick out. It drips like water. If you look at the full line on the dipstick it’s about 1 inch over the full line and the oil is virtually useless. The car also runs an idles rough and it’s constantly idling up and idling down and that’s probably because the gas is leaking into the engine. Please look into this and I appreciate anything you can do. This is definitely a Ford issue. They should be responsible there’s nothing I did to this particles this problem. I maintained my vehicles. I did everything I was supposed to do and this problem arose because it’s defect in the car quite frankly if I would’ve known it, there’s no way I would’ve bought it. I feel the public should know about this and I feel that they should be responsible to fix it. Thank you very much. I appreciate all your help in time. Please feel free to contact me if you have any questions thank you [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I’m a snowbird and in the past 18 months, of which I was in Iowa for 12 months of this time, the dealership has replaced the fuel pump five times. I’m scared to take this vehicle out on the highway. The module that controls the fuel pump has been replaced once. The third replacement I didn’t even get off the dealers lot before it quit
