2020 Lincoln Aviator Plug-in HybridRecalls, problems, MPG & safety

“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…”

“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.”

“Unsure what component failed specifically, has been inspected by dealer multiple times. This randomly occurs while driving. It disables a number of safety features such a collision assist and traction control as well as several driving modes until the car is fully powered off and restarted. There are multiple reports of this occurring frequently in online groups. No warnings prior to the failure but multiple warnings when it fails. This can occur daily, even multiple times a day during normal driving. Dealer has tried replacing multiple modules and sensors but problem persists.”
