2021 Lincoln Aviator problems

ELECTRICAL SYSTEM

I have been having issues with my breaks sticking when applied. To the point that it’s completely stopping my car and i need to use my foot to release the brake from behind. I have had the dealership look at this issue and they can’t seem to find the problem. They also broke my car and claimed they did not feel the sticking. I’ve had the dealership look at my vehicle twice for this issue. It is a safety risk with children in my vehicle. Also everyone i lock my vehicle. My alarm is going off saying someone is opening the door on my Lincoln app. Additionally, every time i start my car it says the passenger door is open, when it’s not. The sync Bluetooth constantly connects and disconnects or if i plug my phone i to the charger for CarPlay it does not work. This biggest problem is my brakes sticking. Like i said when i am braking gradually they are sticking to the floor and not releasing. Thai doesn’t always happen but it has happen a lot recently. I need this fixed!!!!! Multiple recalls that are not available as well

VISIBILITY/WIPER

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.

ENGINE

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. According to the dealership technicians, this may have been caused by thermal stress or frame-related tension. The glass is no longer intact but the remaining components and frame can be inspected upon request. The incident posed an immediate safety hazard to both myself and other road users due to the sudden loss of glass and the potential for debris. I did not observe any warning lamps, messages, or symptoms prior to the failure. After researching the issue, I found that similar sunroof glass failures have been reported across various Ford/Lincoln models, suggesting this may be a known manufacturer defect. The dealership has confirmed the damage but no inspection by the manufacturer, police, or insurance representatives has been conducted at this time.

EXTERIOR LIGHTING

My vehicle’s camera system, including the backup camera, is experiencing an issue where the passenger-side camera fails to display properly, showing only a blank black area. I have reported this issue to my dealership for future inspection. It is not yet clear whether the problem persists during daylight hours; however, it poses a significant safety risk at night when visibility is already limited. The loss of the passenger-side camera view creates a blind spot that could increase the likelihood of an accident or injury.

POWER TRAIN

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. It was found in May 2024 that not only was the charger cable that came with my Aviator when I bought it defective but so was the charger port on my vehicle. The use, value, and safety of my vehicle impaired significantly for several years by this issue. I am reporting this so that there is awareness that the Aviator plug-in hybrid charger port and charger cable can be defective which results in loss of charging capability and could result in a fire.

EXTERIOR LIGHTING

The "auto" mode on my Sync screen on my 2021 Lincoln Aviator does not always automatically switch between day and night based on ambient light levels. This is a blinding experience at night when the screen doesn't switch to night mode and the brightness is intense. This blinding screen makes it hard to see outside when it is dark which could lead to an accident. My dealer says I have the most up to date version of Sync for my vehicle and there is no fix for this problem.
