My 2020 Lincoln Aviator Grand Touring Plug‑In Hybrid has experienced multiple high‑voltage powertrain failures that create an immediate safety hazard. The vehicle has twice lost propulsion while driving, displaying “Powertrain Malfunction / Reduced Power” and “Service Engine Soon” before shutting down completely. During the first failure, the vehicle stopped in active traffic and would not restart; a police officer stopped to assist and called a tow truck because the disabled vehicle posed a roadway hazard. In addition, the digital instrument cluster has repeatedly gone completely black while the vehicle is in motion, eliminating all visibility of speed, gear position, warning indicators, and hybrid system status. During the most recent blackout, an [XXX] child was in the vehicle with me, significantly increasing the danger. These failures are accompanied by hybrid‑system fault code P0A1E (Starter/Generator Control Module), a pink charging‑port indicator signaling a charging fault, and irregular hybrid‑battery behavior (range not updating, battery not depleting). The vehicle has been inspected four times by authorized Lincoln/Ford dealers and has been out of service more than 34 cumulative days. Although the P0A1E code and symptoms were documented, the dealers repeatedly stated they were “unable to verify” the concern and returned the vehicle unrepaired. Required high‑voltage diagnostics were not completed. The problem is ongoing, intermittent, and has not been corrected. Sudden propulsion loss, dashboard blackout, and high‑voltage control failures put occupants and other motorists at significant risk. I am requesting NHTSA investigate this as a potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Ever since buying my 2023 Lincoln aviator hybrid, I’ve been experiencing brake pedal issues, a constant pressure and a pulsating feeling when applying the brakes like the ABS is kicking on. I have taken it to my dealership that I bought the vehicle from over four times for the same issue. They keep saying that it’s normal, I see that the old aviators had the same issue on the hybrid system And a TSB was released for it at one point. While driving the vehicle one day it would not stop so I had to slam on the brakes, causing them to lock up temporarily once I did that it seemed to have improved the breaking almost like something was stuck from the factory! Still to this day I still feel the pressure and the feeling like the ABS is kicking on periodically. I have tried taken it into my dealer multiple times and they keep saying that it’s normal. I opened a case with Lincoln but they keep taking the word of the dealer that nothing is wrong with the vehicle.

While driving, the vehicle displayed a “Stop Safely Now” warning and immediately began limiting operation. At the same time, steering effort increased significantly, similar to a loss or reduction of power steering assist, making the vehicle difficult to control. I was unable to safely pull over when the warning appeared and was forced to limp the vehicle into a nearby residential street to avoid traffic. After stopping, the vehicle became immobilized and repeatedly engaged the electronic parking brake. The vehicle could not remain in neutral and required roadside assistance. Towing was difficult due to the inability to keep the vehicle in neutral. The vehicle was inspected by a dealer, and diagnostics identified a high-voltage isolation fault (DTC P0AA6) traced to the air conditioning compressor on the hybrid system. The component is currently being replaced. The sudden shutdown combined with increased steering effort and inability to safely pull over created a significant safety risk.
