2020 LINCOLN NAVIGATOR Complaints

On August 20, 2026, I was driving my 2020 Lincoln Navigator and came to a complete stop at a traffic light. While I was sitting stationary at the light, with no collision, impact, sudden braking, or other event, I suddenly heard a very loud noise that sounded like a gunshot. At the same time, the driver-side seat belt violently tightened and pulled me back into the seat. The seat belt tightened with enough force to leave marks across my chest and stomach. I was able to get myself out of the seat belt, but afterward the seat belt remained extremely tight and locked in place and could no longer be used normally. My vehicle had previously been identified as being affected by a Lincoln/Ford recall involving the seat belt pretensioner. Several months ago, I received notification instructing me to bring the vehicle to a Lincoln dealership to have the recall addressed. I scheduled the repair and brought the vehicle to the dealership approximately two weeks later. At that time, I was informed that the recall had been paused and that the dealership could not perform the repair because Lincoln did not have an available remedy/replacement part. I continued driving the vehicle because Lincoln had not provided a repair or instructed me that the vehicle should not be driven. The seat belt pretensioner has now unexpectedly deployed while the vehicle was completely stationary and without any accident or impact. The Lincoln dealership has informed me that they expect it may take approximately one month to obtain the replacement part needed to repair the vehicle. I have also contacted Lincoln Customer Support, and a case has been opened regarding this incident. I am reporting this because this was a serious and frightening safety failure. The seat belt pretensioner deployed without a collision or other apparent reason and tightened with enough force to cause visible marks on my body. I am concerned that this defect could cause more serious injuries if it occurs to other drivers

On August 20, 2026, while traveling about 45 MPH, I accelerated to merge onto a highway while passing a slow-moving semi, with traffic approaching from behind. The transmission unexpectedly disengaged and the vehicle completely lost propulsion. The gear indicator showed Neutral. The engine rapidly increased RPM/redlined but the vehicle would not accelerate. I pressed the Drive selector to re-engage the transmission. The vehicle lurched/slammed before Drive engaged and propulsion returned. This created a serious collision risk while merging into highway traffic. This is not an isolated incident. For approximately four years the vehicle has intermittently exhibited rough/abnormal shifting or slipping during acceleration, progressively worsening. During a previous loss-of-propulsion incident on a two-lane highway, the failure occurred while passing a semi with oncoming traffic, creating a risk of a head-on collision. We repeatedly discussed the transmission problem with dealership personnel. Because it was intermittent, the dealer said diagnosis required leaving our primary family vehicle for several weeks, without a loaner. The selling dealer, about six hours away, later offered to retrieve the vehicle and provide a loaner, but canceled because no loaner was available. The defect was therefore never successfully diagnosed or repaired. After the August 20 incident, dealer-provided connected-vehicle diagnostics recorded a Powertrain System Fault and TCM codes P27B5 (Transmission Gear Ratio Control Performance), P2796 and P07E6. The vehicle is parked and available for inspection because I consider it unsafe to drive. It is also subject to open NHTSA Recall 26V402/Ford 26S48 involving the transmission/parking system; no remedy is currently available.

The contact owns 2020 Lincoln Navigator. The contact stated while driving 20 MPH, occupied with his wife in the vehicle, he heard a loud explosion noise coming from inside the vehicle, and as his wife leaning forward the seat belt deployed on his front passenger side of the vehicle causing his wife to sustain whiplash and brushing to her chest. A dealer or An Independent mechanic was not contacted. The vehicle was not taken to an independent mechanic or dealer for dignanoses. The manufacturer was not notified of the failure mileage was 124,000. The contact was relating the failure to NHTSA Campaign Number:25V197000(SEATBELTS) However, the part to do the recall repair was unavailable. The approximate failure mileage was 55, 884.

CDF Drum Failure is a known issue to Ford. They have issued a technical service bulletin (TSB 22-2428) to replace poorly designed components that have since been redesigned. The failure mode can cause violent gear shifts (from gear 10 to gear 1) at high speeds, which is a significant safety concern. While driving on the highway, the transmission would not shift between gears and the car lurched. Check engine light came on and I exited the highway immediately. I took my vehicle to be looked at, and they diagnosed the problem as CDF Drum failure. Ford needs to take responsibility for their problematic design in these vehicles.

Both front headlight and rear headlight seals are faulty resulting in a water leak, causing headlight and taillights to become inoperable at 60k miles.

2020 Lincoln Navigator, 10R80 transmission. Following two full transmission replacements, torque converter replacement, valve body replacement, and transmission pump repair, vehicle continues to exhibit hesitation under acceleration, harsh and delayed shifting, loss of power, shaking beginning at approximately 28-30 mph felt through the floorboard, and abnormal fuel consumption. Independent tire shop ruled out tires as cause. Safety Recall O1 for PCM reprogramming remains incomplete on this VIN despite multiple service visits. Vehicle has been at dealership since early-March with no confirmed repair date or Ford engineer visit scheduled

On [XXX] at or about [XXX]., I was traveling on the highway while going up hill to pass a slow moving vehicle, in the passing lane, suddenly lost total acceleration in which a wrench light appeared as if the transmission disengaged. I was able to coast to the into the driving lane, to get to the shoulder of the road in which the transmission engaged back at about 10mph. I was able to continue slowly, to my destination but at lower speeds the vehicle was shaking and shifting hard. I had just purchased this vehicle, used, only having same for about a month. I had to have the vehicle towed back to the place where I purchase same, due to transmission failure on 04/25/26.

Transmission issue: Not shifting properly while on the highway and almost causing a crash by loosing power and shifted into neutral after attemting to accelerate. The next time it occured the transsmission would not down shift and I was not able to accelerate.

Regularly maintained 2020 Lincoln Navigator at 78,000 miles experienced engine failure with no warning. No check engine light until we experienced power issues and engine shuttering. We took the vehicle directly to the mechanic within an hour of check engine light. They changed the oil and said to go to the dealer. Dealer assessed the vehicle as follows: Bottom end failure of the short block which caused a knocking noise. Confirmed metal debris in the engine oil. Seals failed and leakage occurred. Recommend complete engine replacement. This is the same issue occurring in newer models. Recalls and class action lawsuits filed due to this exact issue. This is premature engine failure requiring complete engine replacement on a 5-year-old vehicle. Major safety concern since the engine can seize up at any time. Imagine going 70 miles per hour down the highway and your engine seizes up with semi trucks around you, and your entire family is in the vehicle. This is beyond unacceptable. Now Lincoln expects us to pay $15,000+ for a new engine. Federal and state oversight organizations are created and funded by our taxpayer dollars to stop these problems and hold these manufacturers accountable. Please do something about this failure.

Faulty Transmissions even after replacement. Fluid leaks and abrupt starting / stopping with it. Dealers can't seem to figure it out and have become a safety issue
