2019 Lincoln Navigator: jerking or lurching

Filed Oct 6, 2026 · Transmission · IL

Vehicle: 2019 Lincoln Navigator (equipped with 10R80 10-speed automatic transmission). Incident Description: While operating the vehicle in normal traffic conditions, the transmission experiences severe internal hydraulic failure, resulting in a violent jolt/jerk. Immediately following this event, the vehicle’s Powertrain Malfunction Indicator (Wrench Light) illuminates, and the vehicle enters a fail-safe "limp mode." Once in this state, the transmission suffers a complete loss of gear engagement, effectively locking the driver out of acceleration. The vehicle actively resists or completely refuses to engage Drive (D) or Reverse (R), causing an unexpected loss of propulsion while navigating heavy public roadways. To temporarily regain vehicle control, the ignition must be cycled completely off and on. A certified franchise dealership diagnostic scan confirmed severe internal mechanical degradation with heavy metal debris suspended in the transmission fluid, destroying the transmission assembly and damaging the Transmission Control Module (TCM). Diagnostic Trouble Codes (DTCs) Present: P0868:00 (Transmission Fluid Pressure Low), P2701:00 / P2703:00 (Clutch Friction Element Apply Time Faults), P07E6:00 (Transmission Park Valve Circuit Stuck), and P1674:00 (Control Module Software Corrupted). Safety Hazard: The sudden and unpredictable loss of forward propulsion and gear engagement forces the vehicle into an immobilized state without warning, creating an imminent risk of a rear-end collision or leaving the driver stranded in live, high-speed traffic. This is a known systemic component defect (addressed in Ford TSB 23-2120) that poses a severe, active safety hazard to occupants and surrounding motorists. The vehicle has experienced intermittent jerking for over a year, but experienced a complete powertrain failure and loss of gear engagement on 10/6/2026.

After 3 failed diagnoses with various vehicle repair shops that could not fix our problem, we took our 2019 Lincoln Navigator to the Phil Long Ford/Lincoln dealership 26 days ago. After expressing my concerns about our vehicle jerking into gear and intermittently losing accelerator power during driving, the dealership diagnosed it as a problem with the cam phasers. Upon picking up the vehicle and asking the CSR if a test drive had been done multiple times beforehand, we arrived, paid our bill, and took the vehicle for less than 30 seconds before realizing the same issue was persisting. My wife and child are the primary occupants at most times, and losing power on the highway and on side roads is most concerning. As of two weeks ago today, I was called by the CSR at Phil Long Ford to let me know that calls and reports were made to Lincoln specifically and that the General Managers would be pooling money together to find a resolution and eventually fix my vehicle. The CSR also said that by the following day (Tues), I would know about a resolution. 2 weeks later (today), I called and requested a manager call me to discuss the situation. No call was made. I also reached out to the CSR and was told that my case was still in a holding pattern. We have now had to rent a vehicle 3 times to help us get around, with no assistance from the dealership except for 2 out of the 26 days we've been without a vehicle. After doing more digging, there is a large class action lawsuit in motion that covers exactly what we are going through. As of 8 days ago, Ford's request to dismiss the suit was denied. We believe at this time there is gross negligence by Ford & Lincoln and have first hand accounts of how scary these vehicles can become while on the road. To top it off during my visit to the dealership this evening, the service manager gave me two options when asking about a possible loaner or rental vehicle: approve the repairs needed on my own dime or continue driving the vehicle.

Well, the problem is with the transmission. The transmission will lurch, and it also will go into neutral while you are driving down the road, the other thing with the suspension I had repaired. But it said the drive modes were disabled and kept on throwing. Check engine lights. Not to mention, I had to have the cam. Phasers fixed last year, that was another $5000 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!

Transmission just revs & does not shift gears when try to take off from traffic lights or merge on highway. Shifts gears aggressively at speeds of 30-40 mph. Herky jerky and causes whiplash Lincoln reports fixing issue but I don’t think they did Safety issue.
