2021 Lincoln Navigator Complaints

While driving, the vehicle repeatedly hesitated during gear changes, lost power, and then abruptly jerked back into gear. This occurred intermittently for over a month without any warning messages, creating unpredictable and unsafe driving conditions. As the issue worsened, the vehicle began losing power more frequently. The most serious event occurred at highway speed, where the vehicle suddenly lost propulsion in the middle of active traffic, nearly causing a stall. This created an immediate safety hazard for myself and surrounding drivers. After several seconds, the vehicle violently re-engaged into gear and surged forward. Only at this point did the vehicle display a warning: “Powertrain Malfunction / Reduced Power.” I scanned the vehicle and retrieved DTC P0734 – Gear 4 Incorrect Ratio, a code associated with internal transmission faults. A dealership inspected the vehicle and reported that the CDF drum had failed. They stated they could not guarantee that replacing the drum would...

I am reporting a serious safety concern involving a 2021 Lincoln Navigator with factory equipment only. After snowfall, during factory remote start, the vehicle produced a hot/burning smell, and I observed visible melting and bubbling of multiple driver-side and passenger side exterior pillars. The vehicle has a factory sunroof and no aftermarket electronics or modifications. The melting appears on the exterior, indicating heat originating from inside the pillar cavities. Due to concern for electrical overheating and fire risk, I discontinued using my remote start. A Lincoln dealership dismissed the concern and incorrectly stated that there is no electrical wiring in the pillars. Lincoln Customer Care has verbally refused assistance solely due to lack of extended warranty and has declined escalation, despite the reported fire risk. I am concerned this involves water intrusion from the sunroof drainage system contacting powered body or airbag wiring, creating a risk of electrical...

Navigator transmission goes into neutral when accelerating at speeds of 50+. Trans completely overhauled. Still does it. Almost had 2 accidents when changing lanes on the freeway, trying to accelerate and instead slowing down with cars behind fast approaching . When trying to pass on a 2-lane hwy, this would be deadly.

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 ca...
