2019 Lincoln Navigator

I purchased this car used. The local lot did not disclose this well-documented history with the Navigator's transmission. I had recall work done a few months ago at an authorized Ford dealership. No warning. The vehicle stalls and pauses during acceleration (the engine does not die). This transmission issue is both dangerous and alarming, as I am unable to complete a pass. The car coasts in neutral (with traffic approaching/oncoming) during attempts to pass other vehicles.

To Whom It May Concern, I am submitting this complaint regarding a serious and costly transmission issue with my 2019 Lincoln Navigator. At approximately 114,000 miles, the vehicle’s transmission failed and required a full rebuild. The total repair cost was around $8,000, which I had to pay out of pocket. When I brought the vehicle to the dealership for diagnosis and repair, the technicians expressed surprise that no recall had been issued, noting that they have seen this same transmission issue in other 2019 Lincoln Navigators. They acknowledged that this appears to be a known and recurring problem among vehicles of this make and model. Before the transmission failed completely, I experienced slipping gears, hesitation, and delayed acceleration, which posed a serious safety risk while driving. These symptoms could have easily caused loss of power or unexpected shifting at highway speeds or during traffic maneuvers, putting myself, my passengers, and others on the road in danger. Sudden power loss or gear malfunction in such situations could lead to an accident or loss of control. The repair process also left me without a vehicle for over three weeks, creating significant inconvenience and hardship. Given the high repair cost, the time without transportation, and the well-documented pattern of similar failures among this model, I believe this issue points to a defect in the transmission’s design or manufacturing. I respectfully request that the NHTSA investigate this matter further to determine whether a recall or manufacturer reimbursement should be issued for affected owners. A recall or refund program would help address the substantial financial burden and potential safety hazards caused by this widespread transmission problem. Thank you for your time and attention to this matter.

Is all on google this particular vehicle Lincoln Navigator 2019 L have problems on the transmission gear malfunctioning…I barely purchase this exactly model a few days ago and I have this issues concern safety so dealer said is purchase with no warranty but this vehicle have 75000 miles only … we should have the attention on this matter because is safety and costly to repair

About 5 weeks ago, our Navigator's transmission had a mild slip, like it was accidentally put in neutral. Since there was no visible warning sign, check engine light, or clear indicator of transmission issues, we thought it may just be a fluke. Within weeks, the transmission slipping escalated from mild to extreme, causing major safety concerns. When in drive, it would struggle to accelerate, get stuck in the wrong gear, then overcompensate, violently jerking into the correct gear 20+ seconds after it should have. A few times, we narrowly avoided getting rear-ended or rear-ending others. Lincoln service confirmed the 10-speed automatic transmission in the 2019 Navigator is problematic and will likely need a full rebuild, yet there is no transmission recall. They also stated their service department was backed up 4-5 weeks due to transmission repairs. Over the last 2 weeks, we've had a full vehicle diagnostic and repair. The mechanic replaced both leaky transmission coolant lines and completely rebuilt the transmission. He confirmed the check engine light never activated and diagnostic trouble codes never generated. That is an extreme safety problem. According to Lincoln, with leaks and transmission slipping, DTCs should be generated, and check engine lights should come on, but it didn't happen in either case. Please investigate both the transmission failures and the trouble code generation!

POWERTRAIN MALFUNCTION/REDUCED POWER while on the highway! Low boost power malfunction causing excessive fuel and oil consumption, spinning/timing misfire, and reduced speed! Check engine light and powertrain malfunction lights later indicated P0365 and P0369 error codes. Dealership says I need a new timing chain and VCT selenoid. I found out this is a KNOWN ISSUE WITH 2018-2020 LINCOLN NAVIGATORS and that Lincoln has issued TSB Bulletins regarding these very issues! I am experiencing all of the symptoms - rattling when starting from a cold start, excessive oil consumption, spinning/misfiring when changing gears, crazy slow acceleration, low fuel economy. Initially the light came on in October with the Lincoln app telling me incorrect oil so I went and had my oil changed 10/30. It didn't help at all. I had the car diagnosed locally before calling to have it scheduled to be fixed at the dealership. The auto place wouldn't even give me a quote!! I have attached their Diagnostic. The dealership stated the cost would be $5400 for VCT Selenoid and Timing Chain. Dealership also stated this is a known issue and he had the same vehicle of the same year for the same reason he's working on right now! I looked it up and Lincoln KNOWS! They know about this issue!! I contacted Lincoln and they REFUSED to help!!! I believe Lincoln should extend grace and help with the cost of repair because they have know about this ongoing issue. Instead of helping their customers by issuing a recall or optional service help, they're putting the bill on the customer or their known issue.

No warning light on dash. Issues engaging in gears. Avoided a few accidents by throwing on hazards when car wouldn't accelerate on road. When turning into oncoming traffic it wouldn't engage in gear but thankfully they braked to avoid hitting me. After that I would only drive in the neighborhood to take kids to school. When reading Ford knows this issue but still put this 10 speed transmission in vehicles. Mechanic diagnosed and had to rebuild transmission.

The contact owns a 2019 Lincoln Navigator. The contact stated that the vehicle would jerk upon depression of the accelerator pedal while driving at various speeds or after coming to a complete stop. An unknown transmission message was displayed on the instrument panel after the failure. The contact took the vehicle to the dealer where transmission fluid was added; however, the failure persisted. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.

The 10 speed transmission in our car shudders and vibrates badly and gets stuck in very high gears. The problem happens most often between 17-23 miles per hour, and is most noticeable on inclines. instead of downshifting to a lower gear at lowers speeds, the car is stuck in 6-7-8 gear. This causes a long hesitation where we are worried we could get rear ended or hit at an intersection. We have been shifting the car manually with the paddle shifters to drop into a lower gear, but this also takes time and causes a delay. We have been to the dealer at least 5 times for this issue and no luck on a repair. the problem has been ongoing for over a year now. Thank You.
