2017 Lincoln Navigator Complaints

VEHICLE SPEED CONTROL,LANE DEPARTURE — Filed 08/01/2025

NHTSA Complaint — 2017 Lincoln Navigator Output Speed Sensor / Lead Frame Vehicle: 2017 Lincoln Navigator 4WD Transmission: 6R80 6-speed automatic Component: Transmission — Output Shaft Speed Sensor / Internal Lead Frame Current Mileage: 219,000 Complaint description: I am filing this complaint regarding a recurring transmission-related problem with my 2017 Lincoln Navigator. The vehicle has experienced intermittent loss of the vehicle speed signal, and the speedometer will suddenly drop to zero while driving. The vehicle has also experienced intermittent wrench/limp-mode symptoms and abnormal transmission behavior. The vehicle was diagnosed with diagnostic trouble code P0722, Output Shaft Speed Sensor “A” No Signal. The output speed sensor is incorporated into the transmission’s internal lead-frame assembly rather than being a simple externally accessible sensor. This problem is concerning because the loss of the output speed signal can affect transmission operation, shifting, vehicle speed information, and potentially cause the vehicle to enter a failsafe/limp mode while driving. The problem has occurred while driving and can create a safety concern, particularly when traveling at highway speeds. I am concerned that the internal lead-frame/output-speed-sensor design may be prone to failure and that owners may be required to perform a significant transmission repair to replace a sensor that can cause a loss of vehicle speed information and transmission control. I am requesting that NHTSA investigate complaints involving the 6R80 transmission output speed sensor/lead-frame assembly in 2017 Lincoln Navigators and other Ford/Lincoln vehicles using this transmission to determine whether there is a safety-related defect or pattern of premature failure. I am submitting this complaint so that the problem is documented and considered as part of any investigation or safety action involving this component.

ENGINE,FUEL/PROPULSION SYSTEM — Filed 03/01/2026

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)

FUEL/PROPULSION SYSTEM — Filed 07/19/2025

The throttle body went bad while driving 55mph and 35mph. Over 5 times I could not accelerate while stepping on the gas peddle and it would stall out trying to get it to ford on the same road for 5 miles. I had to quickly stop and turn it back on with my flashers going less than 35mp on a 55mph road. This happened at first going around a corner you can not stop on due to no visual on the other side which would cause a wreck stopping there. The problem was confirmed by Coughlin of Heath Ford and they were the ones that fixed it. There was no warning of the throttle body going bad until it happened at that moment and repeated to happen as I tried to get it to ford on the same road it was happening on into town. The check engine light did come on but it it would go on and off during the situation until it finally stayed on after a few minutes. There is a photo of the report attached to this document.

UNKNOWN OR OTHER — Filed 03/01/2025

Back-up camera quit working about 3 months ago, 2025. There is a recall for the 2018 cameras but this is a 2017. Please include the 2017 year in the recall list. This issue poses a safety hazard when backing. Driver can not see what is behind the vehicle or if it is in a dangerous position. Since this is a SUV sized car the side mirrors are not adequate to safely see what is behind the car when backing. We have had a few close calls but no injuries yet.

EXTERIOR LIGHTING,UNKNOWN OR OTHER — Filed 03/15/2025

Recall number 25S08 for side mirror lighting, the disconnect remedy is unacceptable. These side lights provide safety measures for exiting and entering the vehicle. As older adults seeing the fold out step in the dark is necessary. If these lights are disconnected due to the recommended remedy from Ford then there is a fall hazard for owners who don't see well at night. The steps could be missed resulting in a fall. WE request the lights be replaced or repaired NOT disconnected. Recall documents mailed from FORD/Lincoln to my address March and June 2025

You can not see behind the vehicle when the camera malfunctions The vehicle has not been to the dealer for the issue yet when the camera does not work there is a error message

SERVICE BRAKES — Filed 01/18/2024

The brake booster on a 2017 Lincoln Navigator does not work properly, causing increased force to brake, a brake pedal that does all the way to the floor, and increased distance to come to a full stop. A recall was issued (22V-150/22S11) on the master cylinder and brake booster. The master cylinder was replaced in November 2022 (prior to my ownership) but not the brake booster. The brakes have been an issue since I purchased the car in January 2023. I tried several times to get the dealership to assist me but was never able to get the help that I needed. I recently took the car in to have the brakes addressed and now have to pay out of pocket to have the brake booster fixed. I was told that the warranty for a recall is only good for 12 months which I was never informed of at the time of the vehicle purchase.

VISIBILITY/WIPER,BACK OVER PREVENTION — Filed 07/21/2023

My vehicle is a 2017 Lincoln Navigator. The Backup Camera works maybe 50% of the times that I attempt to back up. I understand that Lincoln has a recall on other Lincoln vehicles for this issue, but not for the Navigator. The Cross Traffic Alert does not work. In combination, attempting to back up has a real potential for a vehicle crash or pedestrian injury, especially in parking lots, for drivers of the Lincoln Navigator. Thank you.
