Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My 2021 Lincoln Aviator grand touring PHEV has on 3 separate occasions randomly gone into “brick” mode where power is to some components like the Sync screen, and some lights, but main dash won’t boot, the lock/unlock doesn’t work but lock icon flashes on door panel, the vehicle won’t start. This is after short trips out with my family for the evening. Not a fob issue. All 3 times the same. First occurrence at just over 11,000 miles, again in Sept 2023, and happening again June 2025. Roadside assistance dispatches tow trucks, the vehicle can never be jump started. …”

“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. …”

“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. …”
