My screen intermittently goes black, I have had it repaired/ updated once prior and it still does this..as a result I backed into a mailbox. It was very dark and I couldn’t see out of my windows.
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.
