2019 Lincoln Navigator: sudden loss of power

Filed Apr 28, 2026 · Transmission · TX

The vehicle is a 2019 Lincoln Navigator. The component that failed is the transmission. The vehicle experienced a sudden transmission failure resulting in loss of normal drivability. The issue is currently available for inspection at the repair facility upon request. This failure created a safety concern due to loss of power, hesitation, and unreliable shifting, which can increase the risk of collision, particularly in traffic or during acceleration. The problem has been confirmed by the dealership and independent repair facilities. Multiple repair professionals indicated that this failure is consistent with a known issue addressed by a Ford Technical Service Bulletin (TSB), suggesting this is not an isolated incident. The vehicle has been inspected by the repair facility. The manufacturer has not directly inspected the vehicle to my knowledge. There were no significant prior warning indicators that would suggest imminent failure. Any symptoms prior to failure were minimal or not clearly indicative of a major transmission issue. Based on information from repair facilities, this appears to be a known defect pattern rather than normal wear or maintenance-related failure. The use of a TSB instead of a recall raises concerns that a broader safety-related defect may not be adequately addressed. This failure occurred after proper maintenance and outside any initial waiting period for warranty coverage. The issue appears systemic and warrants further investigation.

While driving on highway on several occasions, transmission jumps out to neutral causing sudden loss of power specially when accelerating. This was rarely happening since 2022 but it started to get worse recently happening more than four times in 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.

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 federal safety agency 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.

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.
