2019 Lincoln Navigator: check engine light

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.

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!

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.
