2021 Lincoln Aviator Visibility & Wipers Problems

The driver-side front window regulator failed and was replaced on October 4, 2025. The passenger-side window regulator also failed and was removed and replaced on November 21, 2025. At the time each incident, the window would not raise using the car controls and remained stuck in the down position. Two window regulator failures on opposite sides of this vehicle just seven weeks and within roughly 2,400 miles apart does not indicate typical wear. It reflects a pattern failure consistent with a component defect. At the time of the October incident, I was actively driving the vehicle and the November incident when was while the car was parked, when the window failed and would not raise. After parking and then restarting my vehicle, the window remained fully or partially down and could not be returned to a closed and secured position. This created multiple safety and security risks, including: • Inability to secure the vehicle against theft or intrusion • Exposure to weather, rain, or debris • Increased cabin noise due to broken window • Risk of vehicle damage while parked without protection. The vehicle was left parked and unsecured solely due to the window malfunction. No police or insurance inspection occurred, as the incident did not involve a collision or theft, though the vehicle was left unsecured. The failure was diagnosed and confirmed by the manufacturer, Lincoln and independent service center Firestone Complete Auto Care, who completed the repair. There was No warning lamps or dashboard messages that appeared prior to or during the failure. Both window regulator failed suddenly and without warning. In my research, numerous Aviator owners have publicly reported identical regulator failures, (Reddit and YouTube) which further reinforces that this is a systemic issue, not an isolated event.
