2018 Lincoln Navigator Owner Complaints

We purchased a 2018 Lincoln Navigator L in 2022 with 29,489 miles, and it has been great. We are at 64,351 miles, and it is making the cold-start rattling noise. We have called Lincoln for assistance, and they are refusing to help. They stated that there is no help. I took it to Duval Ford, and with other issues such as the water pump and leaks, they quoted 12,000 to fix this truck. They did say they had a payment plan to fix the vehicle. When the soft pull was opened in 2022, our truck did not make noise at that time. I believe Ford should stand by their product, and there are so many videos on YouTube addressing this vehicle.

The other weekend, we were unloading the back of the Lincoln when all of a sudden the liftgate came down on us. Fortunately, we were able to back away in time... Later that weekend, my son was unloading the back and it came down and hit him in the head to the point it made him cry (and he is a tough kid at 13)... I have brought up this concern with Lincoln at least 3 or 4 times, and they said it has been fixed, but clearly there is still a safety concern here. The last fix was a new harness they had to install. I have had so many issues with this vehicle, I feel like they dont want to fix it anymore... This has happened at least a dozen times or more where we are unloading the back, just standing behind the bumper and the automatic liftgate activates and comes down.

The vehicle has experienced repeated mechanical failures involving the engine, cooling system, drivetrain, and electronic systems. Documented failures include the navigation/APIM module, transmission jerking and drivability issues, transmission valve body concerns, cam phaser failure, driveshaft repair, front wheel bearing/IWE failure, coolant leaks from heater core hoses, and engine vibration requiring extensive diagnostic work including a short block engine repair. The vehicle has also experienced multiple overheating incidents despite prior repairs. Overheating occurred in May 2025, December 2025, and February 2026. During these events the engine temperature rose abnormally and coolant had to be added to the reservoir. Drivetrain problems including transmission jerking, vibration, and driveshaft repair also created drivability concerns while operating the vehicle at highway speeds. These issues have been inspected and confirmed by an authorized Lincoln dealership service department. Numerous repairs and diagnostics have been performed including APIM replacement, cam phaser repair, heater hose replacement, wheel bearing/IWE replacement, driveshaft repair, and engine diagnostic work approved through warranty processes. Symptoms prior to failures included overheating, vibration, excessive fan noise, whining while driving, and transmission jerking. The vehicle and components are available for inspection upon request. The repeated overheating events combined with drivetrain and engine failures raise concern that this vehicle may have an underlying safety-related defect that could result in sudden loss of power or engine failure while operating in traffic.

Vehicle: 2018 Lincoln Navigator VIN: [XXX] Component: Steering Mileage: 103899 Complaint Narrative: I recently purchased a 2018 Lincoln Navigator and took delivery on December 10, 2025. Within days of delivery, I observed a metallic contact noise originating from beneath the steering column. The noise occurs consistently when the vehicle is turned off, within one to three seconds after ignition off, and intermittently while driving during steering input, particularly while making turns. The sound is best described as metal on metal contact, not an electronic relay or normal operational noise. The condition appears load dependent and reproducible. The steering response remains functional at this time, and no warning indicators are present. However, because the noise occurs during active steering, I am concerned about possible mechanical interference, wear, or binding within the steering column or related steering components, which could worsen over time and affect steering control. The vehicle has a prior manufacturer buyback history from 2021, and I am documenting this concern to ensure that any steering-related condition is evaluated and tracked as a potential safety issue. I have scheduled a service appointment for diagnostic evaluation. This complaint is submitted to document a steering system concern identified immediately after purchase and delivery, involving noise during active steering operation.

Front differential - entire system needs to be rebuilt due to bearings going bad. While the vehicle has not ceased up due to the differential bearing, it is a Safety issue and known to Ford. Note this is the second time I’ve personally had to have the front end rebuilt in this vehicle. First time at 79,000 miles and now again at 149,000. Giving me a 70,000 mile service life. How is that possible that a differential only last 70,000 miles.

The moonroof drain hoses are not secured and is known problem with other Navigator and Expedition owners. I became aware while troubleshooting why the liftgate would not open. The procedure to access the Rear Gate Trunk Module (RGTM) requires the removal of the 3rd row seats, C & D pillars and several cabin panels. After the removal of these items I noticed the insulation under the carpet and behind the panels were drenched. The Reserve trim on my Navigator has very dense carpet and a backing that does not let the moisture evaporate over time. Rather, it retains water almost indefinitely. Upon removing these items and the front row kick panels, I discovered the water was 3” deep. Because of this leak, the water submerges numerous wiring harnesses throughout the cabin that affects nearly all computer modules. It is also the root cause of my liftgate not opening issue. Per the 2018 Lincoln Navigator/Ford Expedition Electrical manual, there is a splice of the VBATT Always Hot wire under the front drivers kick panels. Despite the factory shrink wrap, water penetrated this splice and corroded the copper wire resulting in an open circuit. I repaired the wiring and solved the liftgate issue. I also went thru the painstaking process of remediating the water damage. Of bigger concern, is the amount of corrosion on other wiring connectors and splices that is unknown at this time. I believe this defect is a safety hazard of unknown proportion given the various modules dependent on the submerged wiring. There is also a health concern of mold growing due to the carpet backing not permitting moisture to evaporate. On the cosmetic side, there visual water stains on all four sides of the headliner. When I reconnected the right rear failed drain hose, I secured it with a tie wrap. I believe Ford should take ownership if this defect and use tie wraps to secure all 4 drain hoses at no charge to mitigate the damage and health impact.

The same problem that is currently being reported by the NHTSA for the Ford F-150 has been happening to my Lincoln Navigator for the past few years. During higher-speeds (50 mpg and over) the auto will lurch forward as if trying to shift gears and has, on more than one occasion, actually downshifted into a lower gear while driving on expressways, forcing me to pull-over, stop the engine and restart in order to get the auto back into normal operation. When this downshifting occurs, a graphic appears on the dashboard. This graphic shows a stick-shift icon and also includes the words "Manual Shifting". However, the exact words cannot be verified since the graphic only stays visible for a split-second. Since I'm a bit shocked when this happens, my concentration is on safety and not on the specifics of a dashboard graphic. When I have taken the auto into service and mentioned these occurrences, the service persons have always stated that the computer system has been updated and the problem is marked solved. I have a warranty of 100,000

Dealership Responsible: Ted Britt Ford of Chantilly Dealership Address: 4175 Auto Park Cir, Chantilly, VA 20151 Complaint Details: I purchased a 2018 Lincoln Navigator L Black Label, and since then, I have experienced multiple serious mechanical failures due to an improperly performed cam phaser repair by Ted Britt Ford of Chantilly in 2020. The dealership’s service department performed a faulty installation, which resulted in: •Missing and broken screws in the cam phaser system •Jerking, rattling, and acceleration issues •Significant engine damage requiring a complete short block replacement As a result of this in negligent repair, In 2024 I had to replace the cam phaser again, along with replacing the short block of the engine due to the extensive damage caused by the dealership’s poor workmanship. In addition to this issue, I have faced multiple other failures, including: •Valve body replacement •Wastegate failure •Rear heat stopped working •Steering column failure These problems have caused frequent breakdowns and safety concerns, making the vehicle unreliable. The constant need for repairs raises serious questions about the quality of Lincoln’s engineering and service network. This issue is not an isolated incident, and I strongly urge NHTSA to investigate potential defects in the 2018 Lincoln Navigator and to hold dealerships accountable for performing unsafe and defective repairs. Requested Action: I request an investigation into the faulty cam phaser repair process and whether similar issues are being reported by other 2018 Lincoln Navigator owners. This could indicate a larger systemic defect or a trend of poor-quality repairs in Ford/Lincoln service centers

The side mirrors, which are power adjusted, either will not properly adjust to the same setting when they first fold out when you start the car, or they will start moving when you start driving. This happens nearly every time the car is started. I have talked to fellow Ford F-150 owners who have the same problem. This causes a serious safety concern, especially when they start adjusting as you start driving because then you cannot safely see any obstacles beside the car and the warning light if someone is beside you does not work effectively. If I start my car and go to back out of a parking spot or driveway and the mirror start adjusting so suddenly I'm looking at the pavement instead of what is beside me, you can see why that would pose a safety concern to myself and anybody who may be passing by.
