   My husband secured our infant into the car seat and attached the seat to the base installed in the car. He then drove our child. When he removed the car seat it was discovered the right side of the seat (when facing) was not clicked in and could be lifted up. When he removed the seat he noticed the clip on the inside of the shell, that connects to the base, was completely missing meaning he had been driving our child only partially secured. When we turned the car seat to take a picture the retractable clip on the outside of the same portion fell out. We just got this car seat in XXX (new) and have only used it since our son was born at XXX. He is [XXX] old and well below the weight limits.

   I am reporting a serious intermittent transmission and loss-of-propulsion problem with my 2021 Lincoln Navigator, VIN 5LMJJ3LT6MEL05416. While driving, including at highway speeds, the transmission will unpredictably behave as though it has shifted into Neutral even though the vehicle remains in Drive. When I press the accelerator, the engine responds, but the vehicle temporarily has little or no propulsion. The transmission may then suddenly re-engage and slam or bang forcefully back into gear. This can also happen under very light throttle. I may gently press the accelerator expecting normal acceleration, but instead the vehicle acts as though it is in Neutral before suddenly engaging again. The condition is intermittent and cannot be reliably reproduced on demand, which makes it especially dangerous and unpredictable. I am concerned about losing propulsion while merging, passing, entering traffic, or attempting to accelerate away from another vehicle at highway speeds. The vehicle has previously had transmission adaptive learning/reset procedures performed, but the problem continues. I am aware that Ford/Lincoln has issued technical service information addressing momentary neutral-out, delayed engagement, harsh engagement, and other 10R80 transmission concerns on this generation of Navigator. I am also aware of Ford recall 26S48 / NHTSA recall 26V402 involving certain 2018–2021 Lincoln Navigators. I am not claiming that the recall is definitively the cause of my specific condition, but I believe this intermittent loss of propulsion presents a serious safety concern that should be investigated. I am requesting that NHTSA document and investigate this loss-of-propulsion / neutral-out condition because the vehicle can unexpectedly fail to accelerate and then violently re-engage the transmission while in motion.

4. Filed Jul 9, 2026Failure Sep 21, 2025Hanson, MAFuel/propulsion system, Power train

   I purchased this 2021 Lincoln Navigator L Black Label used on March 22, 2024 with approximately 42,726mi. Beginning around Sept. 2025 (approximately 70,000-75,000 miles), the vehicle developed intermittent transmission failures that have progressively worsened. This is our primary family vehicle and routinely transports our three young children. The transmission hesitates, slips, skips gears, bangs into gear, and frequently delays engagement before suddenly surging forward. Engine RPM increases without corresponding acceleration. Occupants are abruptly thrown forward and backward during normal driving. Several times each month, a yellow wrench/powertrain warning appears instructing the driver to see the owner’s manual. When this occurs, the vehicle loses normal acceleration and throttle response becomes significantly delayed. The defect is intermittent and unpredictable. The condition creates dangerous situations when merging, entering intersections, accelerating from traffic lights, and in stop-and-go traffic. On one occasion, after stopping on an incline, the vehicle would not accelerate and effectively became disabled in traffic. We activated our hazard flashers while vehicles drove around us. The hesitation followed by sudden engagement also creates a rear-end collision risk. I first brought the vehicle to an independent repair shop, but the concern was dismissed. On 6/22/2026, Herb Chambers Lincoln of Norwood road tested the vehicle, confirmed the complaint, and documented that the “transmission is skipping and banging into gears” and recommended complete transmission replacement. The estimated repair cost was approximately $12,560. The vehicle remains unsafe to drive due to repeated loss of propulsion, delayed acceleration, violent shifting, and dealer-confirmed transmission failure. I respectfully request NHTSA investigate whether this represents a broader safety defect affecting Ford/Lincoln vehicles equipped with the 10-speed automatic transmission.

9. Filed Feb 10, 2026Failure Feb 2, 2026Kingsville, TXEngine, Power train, Vehicle speed control

   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 resolve all issues and provided two estimates: $5,600 for a partial internal repair/$8,700 for full transmission replacement. The 10R80 transmission has a documented history of failures, including harsh shifting, slipping, unexpected gear disengagement, and internal component defects. These issues are addressed in multiple Ford Technical Service Bulletins involving P0734, harsh/failed shifts, and failures related to the CDF clutch cylinder/drum. Many vehicles of the same make and model are covered under related recalls or service actions for similar problems; however, my VIN is not included, and Lincoln declined to honor the existing recall. This defect presents a serious safety risk due to: Sudden loss of power while driving, including at highway speeds, Unpredictable re-engagement and violent surging, Loss of propulsion without warning, leading to near-stall conditions. This powertrain malfunction is a known, unsafe, repeat issue among these vehicles equipped w/this transmission.

10. Filed Jan 12, 2026Failure Dec 14, 2025Chambersburg, ILElectrical system

    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 fire. I am requesting NHTSA review this as a potential safety defect involving electrical overheating and fire risk.

    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.

    Car purchased in Feb 2022. November 9, 2023 after a couple of previous complaints about the car riding rough, this time , after telling them the car jumps and throws into the next lane, it was diagnosed as having passenger rear leaking strut, front pinion seal leak, front driveshaft c/v joint torn and leaking grease. These were repaired under warranty. Dec 2024: had noise and had vibration felt through floorboard - diagnosed with problem in front differential and found carrier bearing failure and damage to case from bearing failure/spun. The axle housing assembly was replaced. April 2025: transmission shifting hard and clunk noise as well as riding rough again. These transmission assembly will be repaired for known problems on original 10 speeds but they don’t fix until customer complains, the rear differential pinion seal is leaking and the front struts are leaking. Something is very wrong with the suspension, drive train and transmission in this vehicle.

    [XXX] Wednesday we were traveling from Charlotte NC headed westbound on [XXX], a 6 or 8 lane highway, speed limit 70+ mph, when our 2021 Lincoln Navigator suddenly lurched and the engine completely failed. There weren't any warnings by the vehicle prior to the incident. There were two of us in the vehicle at the time, and we suddenly found ourselves in a situation of extreme risk. It was 4 - 5 pm during rush hour traffic. The driver was able to maintain composure and our tires continued rotating long enough to coast and cross over 3 fast moving lanes to get us slightly off the side of the highway. It was a very frightening and unsafe situation, not only during but after the engine failure, as we were on a very busy, noisy highway not knowing where we were or what to do. We live in Ohio and our plans were scheduled only for 8/25/24 (leave Ohio)-8/29/24 (return to Ohio). Our Lincoln was towed the night of the engine failure to Classic Ford Lincoln in Shelby NC, and it's been there for 7 days. The tow driver could not start the engine. He had difficulty (20 minutes trying) getting it into neutral so he could put it on the flatbed. The total engine failure problem isn't yet diagnosed. Classic is the only one to examine it. We had to extend our NC hotel stay for two days waiting for the vehicle to be repaired. On 8/31 we couldn't wait any longer and had to rent a vehicle from Enterprise to return home; leaving our Navigator in NC. Lincoln Roadside Assistance has been very difficult and inattentive to our dire circumstances. We're now faced with a situation of not having our vehicle, not having a diagnosis, and concerns about whether the vehicle will be dependable when/if it's returned to us. We have to travel often and fear Lincoln could leave us in bad circumstances again even if they can find the current problem and repair it. It seems to be something extraordinary or uncommon or a diagnosis would have happened by now. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

    A grinding noise was noticed during the driver memory function or when manually adjusting the power tilt or telescoping steering column. I took the car to Ford for service and was very surprised to hear that the entire steering column needs to be replaced at the cost of $1700.00. This defect is ONLY covered under the limited warranty. This is obviously a safety hazard if it requires a new motor in the steering column. Upon a quick investigation of the defect, it was learned that this is a KNOWN problem on all Navigators from 2018-2021. Ford KNOWS that this defect exists on certain vehicles and has not issued a recall to correct this. This is not a normal "wear and tear" item that should have anything to do with your warranty. Very dangerous to need a new steering column motor for something that was known by FORD and LINCOLN to have problems in certain production years. Plus $1700.00 is a huge cost for the consumer.
