2022 Lincoln Aviator PhevEngine & coolingFuel system

This vehicle suffers from the low-pressure fuel pump defect tracked under NHTSA Campaign Number 25V455000 (Ford Recall 25S75). Since 2024, the vehicle has experienced a recurring Check Engine Light accompanied by engine hesitation and fuel delivery failures. Because the manufacturer has failed to provide a final recall remedy, the authorized Lincoln dealership repeatedly refused to fix the underlying issue. Instead, they continually cleared the error codes and instructed me to keep driving the vehicle. Operating...

the vehicle with this active safety defect caused severe fuel-management failures and misfires, forcing raw fuel into the exhaust system and completely melting the catalytic converter. The manufacturer is now refusing to cover the catalytic converter under the Federal Emissions Warranty, citing that the vehicle is slightly over 80,000 miles - even though the failure was explicitly documented by the dealer well before that threshold. The lack of a timely recall remedy has directly resulted in secondary vehicle damage, creating an unsafe operating condition and compromised emissions controls.

Once again, my vehicle exhibited immediate and sudden power loss while at highway speeds. Ironically, I was in transit to my dealer for the third time for this issue within my vehicle's 3,000 miles. This is incredibly unsafe at any speed, especially at highway speeds without warning. An uncommanded slowdown without any response from the accelerator pedal, and a warning on the gauge cluster stating "vehicle is slowing down". Cruise control at this time was not operational in the vehicle (another issue) and I was...

using my foot to control the speed. Additionally, the Bluetooth connection was not functioning, the Navigation screen nor map would even load, and I was unable to use cruise control due to an error message "cruise unavailable". We get a separate Lincoln Aviator for a loaner, and not only does reverse park assist not work, the rear camera doesn't function, either. These cars are dangerous and need to be recalled immediately and taken off the road. We plan to sell/trade ours as the soonest possibility and incur whatever financial burden that may come with it. It's not worth my family's safety, or that of someone else.

The rear camera is janky, the collision alert fires off at random times, and now, the main safety issue! Received a huge red triangle on the HUD and NAV screen stating that the "vehicle is shutting down" and then poof, the damn thing shut down immediately without warning. The message was on the HUD and NAV for about a second and a half and it died. The rear camera is janky, the collision alert fires off at random times, and now, the main safety issue!

that the "vehicle is shutting down" and then poof, the [[redacted]] thing shut down immediately without warning. The message was on the HUD and NAV for about a second and a half and it died. Thankfully we were at surface street speeds of around 30-35 and I was in command of the vehicle. This issue has been reported on other GRAND TOURING models of the Lincoln Aviator where people are at higher speeds, such as the highway or expressway. That said, this is my wife's main vehicle and I am terrified, as well as she, to have her driving this at all hours of the day responding to emergencies at her hospital. PLEASE HELP US ALL that own this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Went to get in it this morning, and said no key was detected. Okay, whatever, we'll use a backup code. The screen never prompted for a backup code. We had the key inside the vehicle, so we use the Lincoln Way App to start the car and figured we can get it going from there. Nope, the car was running and everything was going, yet it won't allow us to select Drive, Reverse, or Neutral. Sat there for a bit, fumbling around and nothing worked to get the vehicle in motion. We finally hit enough buttons for the vehicle to...

shut off, we got out, locked the doors, plugged it in, and just allowed it a few minutes to reset. Notta. Got all this on video. I finally had to pop the hood and use the freaking 2021-2023 Explorer / Aviator Hybrid Vehicle Emergency Response Guide to kill 12v power to the thing. After all that, it allowed us to get in and drive normally. However just a few hours later... 2,600 miles on the odometer and we were driving approx 55mph and the Aviator engaged the parking brake for about half a second. Nasty noise, huge bucking from the chassis, and just a split second of extreme confusion and wondering WTF. The red "park brake" was illuminated on the dashboard, and everything seemed normal afterward. However, immediately after that incident it then disabled adaptive cruise control via a message on the dashboard (no cruise worked). We drove home without further incident, called the dealer, and they stated to call Lincoln Roadside Assistance, get it towed back to the dealer that it was just a few days ago, and they'll deliver a loaner to us. A few hours later, it's on the tow truck. This is the second time this vehicle has placed us in danger. The first issue I'll report after this is submitted. Thank you.

CONSTITUENT WRITES REGARDING VEHICLE STALLING ON THEIR 2022 LINCOLN AVIATOR. This is brand new vehicle with 3,000+ miles on it. The first day owned it, around 12-21, the vehicle would not go into drive. A warning message appeared that said 'high-voltage battery warning", "The hybrid powertrain system has detected a fault". It would also flash "Full Accessory Power Active". After some internet searches I found a thread in ford that said "let the car sit for 20mins and it will restart". ...

I did that and vehicle restarted. I made an appt with my local Lincoln dealer, Bill Collins Lincoln, and they inspected the car on 1-18 thru 1-21. They did not find anything wrong with it but did find the codes. They stated they thought the battery was dead. This was impossible due to the fact I drove the car 500 miles from Alabama to KY on 12-21. Today, 2-2-22, my wife was driving home from work and the car shut off on the interstate. When I say shut off, I mean it died at 65mph. She tried to press the accelerator and the car just continued to de-accelerate. The check engine light popped up and said "Stop Safely Now". Luckily, my wife was able pull off the interstate without causing an accident. Once stopped, she turned the vehicle off and tried to restarted it. It popped the same message about "full accessory power" and the car wouldn't start. She tried the push button start to no avail, tried the remote start to no avail. Finally she used her "phone as a key" and it started. She was able to drive home. I have called Lincoln and made them aware of the issues. They have asked for me to bring the car in immediately. I informed them I would be filing a complaint here as well. This car is a $85,000 death trap. Lincoln needs to take this very seriously and an investigation needs to open to find out why this vehicle is behaving like this. It is not safe to drive.

2022 Lincoln Aviator PhevEngine & cooling

On 5 separate occasions my car has given me a warning saying "Stop Safely Now." When I begin to slow down, the car looses all power and I have to coast to a stop somewhere. The first time the car started back up and I was able to drive it again, the following 4 times it had to be towed. Each time I was stranded on the side of the road - once literally on the road because I was unable to get onto the berm because of high snow drifts and the car just stopped, which was a huge safety issue. Each time this has happened...

it has taken approximately 3 hours for a Lincoln approved tow truck to come and get the vehicle leaving me stranded in the freezing cold with multiple children and no heat in my vehicle. My speed has varied each time this has happened. One time I was in park, another time I was doing 60+MPH and the others were in-between these speeds. I have multiple videos of what happens and have provided them to Lincoln. Lincoln has replaced the battery and also the Powertrain Control Module and nether of these have corrected the problem.

A warning appears on the dash "stop safely now" and the vehicle rapidly comes to a complete stop and is unable to be moved. This has occurred on three occasions, during 2 of which the car stalled in an active driving lane on a highway, resulting in life threatening situation. The app said "high voltage battery warning" triggered by "another event". Being investigated by Lincoln, who is re-acquiring the vehicle due to inability to appropriately diagnose and resolve the issue.

I was driving and an alert to pull over came on. The car would not accelerate and I was in the middle of a parkway where speeds were 55 mph. It almost seemed like the car couldn't figure out to go to gas mode when the battery depleted the range. The car is a hybrid.
