For the first 39 months of my ownership my 2021 Lincoln Aviator Grand Touring plug-in electric hybrid would not charge properly and resulted in thousands of charge station fault alerts. The dealership was dismissive of the issue for years because it seemed to work for the few minutes when they charged it on their high voltage charger even though I voiced concerns about the charger port being bad on the vehicle and it not working properly at home. My Aviator would not charge unless the plug was in the exact perfect spot and rarely would make it to a full charge before faulting out. Eventually the port started making SPARKING NOISES, ELECTRIC FIRE SMELLS, and SMOKES when plugged in. I was afraid my Aviator was going to start a fire and burn my house down, so I stopped charging it for at least 6 months until a new service manager finally took the time to investigate the issue. …

Windows, wipers & sunroof

The contact owns a 2021 Lincoln Aviator. The contact stated while driving at an undisclosed speed, the driver's side rear door trim detached and flew off the vehicle. Additionally, the contact stated that after it rained, water entered the interior of the vehicle through the sunroof. The vehicle was taken to the dealer where it was diagnosed with a detached driver's rear door trim and clogged drain tubes in the sunroof assembly. The driver's side rear door trim was not replaced. The dealer repaired the clogged drain tubes in the sunroof assembly. The contact stated that the failure reoccurred. The vehicle was taken back to the dealer; however, the failure was not duplicated. The manufacturer was made aware of the failure. The contact referenced a recall; however, the VIN was not associated with the recall. The failure mileage was approximately 60,000.

1.) Exhaust System Failure (Flex Pipe / Catalytic Converter) The vehicle's exhaust system-specifically the flex pipe connected to the catalytic converter-cracked and malfunctioned. This component is available for inspection upon request. As a result of the failure, exhaust fumes entered the cabin, creating a significant safety risk due to potential exposure to carbon monoxide. Prior to the failure, I noticed a persistent rattling noise at low speeds and while the vehicle was idling. The issue was inspected and confirmed by the dealership; however, I was informed that the repair falls outside of warranty coverage. I would like to know if this falls under safety hazard for emissions. 2.) Sunroof Glass Shattering Incident While driving, the sunroof glass suddenly shattered and appeared to implode outward. …

Powertrain malfunctioning. The vehicle has had multiple neutral out (not reacting) when the accelerator is applied. Occurring in the middle of an intersection 3 times. Stuck in the middle of the intersection has resulted in two (2) cases of almost being hit by an oncoming vehicle. Pulling into traffic from a stop sign and losing the accelerator another time resulting in traffic breaking hard to avoid an accident. Recently while in cruise control on the highway driving 79 MPH, the vehicle suddenly shifted into what had to be the lowest gear lunging passengers forward and slowing to an unacceptable speed for the highway. Almost initiating being hit from the rear by a tractor trailer and just making it off of the shoulder to safety. This may be the result of service bulletins 22-2145 or SSM 50529. …
