2020-2025 Lincoln Aviator Tailgate Hinge & Power Liftgate Problems

Known Issues for 2020-2025 Lincoln Aviator Tailgate Hinges

While there are no specific recalls for the tailgate hinges on the 2020-2025 Aviator, a key Technical Service Bulletin (TSB) for other Ford/Lincoln SUVs with nearly identical power liftgate systems points to a significant known issue. TSB 17-0049 was issued for 2013-2017 Ford Escape and 2015-2017 Lincoln MKC vehicles, noting that repeated manual closing of the power liftgate could cause damage and deformation to the hinge mounting area on the body. This leads to liftgate misalignment, binding, and subsequent power liftgate failures. Given the shared design principles, this is a critical issue for Aviator owners to be aware of, as forcing the power liftgate can lead to hinge and body damage.

Symptoms of a Failing Tailgate Hinge

Hinge failure on an Aviator often masquerades as a problem with the power liftgate's motor or sensors. It's important to distinguish between a bad electronic component and a mechanical issue like a failing hinge.

Power Liftgate Stops or Reverses Unexpectedly

This is the most common symptom. You press the button to close the tailgate, it starts to move, and then it stops and re-opens. This happens because a worn or binding hinge creates extra friction. The power liftgate's safety system interprets this friction as an obstruction (like a person or object in the way) and automatically reverses direction to prevent injury or damage. This can be intermittent, working correctly sometimes and failing at others.

Tailgate Fails to Open

In some cases, the liftgate may fail to open at all when using the key fob, interior button, or exterior handle. You might hear the latch click or a motor attempt to engage, but the gate remains shut. This can happen if the hinge is seized or if the tailgate is so misaligned that the latch cannot release properly.

Creaking, Popping, or Grinding Noises

Any unusual noise during operation is a red flag. A dry, worn, or bent hinge will often produce a loud creaking or popping sound as the tailgate moves. A grinding noise can indicate that metal components within the hinge are worn and making contact. These noises are a clear sign of mechanical failure, separate from the electronic liftgate components.

Misaligned or Sagging Tailgate

Visually inspect the gaps between the tailgate and the body when it's closed. If the gap is uneven from side to side or top to bottom, it's a strong indicator of a bent or failing hinge. A sagging tailgate may also be difficult to latch, requiring extra force to close it completely. This misalignment is often the root cause of the binding that triggers power liftgate problems.

Buying a Used 2020-2025 Aviator Tailgate Hinge: What to Check

A used OEM hinge is often a better choice than a new aftermarket part due to guaranteed fitment and material quality that matches the original factory specifications. However, careful inspection is crucial.

1. Confirm the Correct Side

The left (driver-side) and right (passenger-side) tailgate hinges are not interchangeable. They are mirror images of each other. Always confirm you are purchasing the specific side you need.

2. Inspect the Mounting Points

Look closely at the bolt holes and the flat surfaces where the hinge mounts to the body and the tailgate. Check for any signs of stress, such as hairline cracks in the paint or metal, or any deformation or bending. A hinge that was removed from a vehicle with a damaged mounting area may be compromised itself.

3. Check for Smooth Movement

Hold the hinge in your hands and pivot it through its full range of motion. It should move smoothly without any gritty feeling, binding, or catching. Any resistance you feel by hand will be greatly amplified when trying to move the entire weight of the tailgate.

4. Look for Corrosion or Damage

While significant rust is less common on these newer vehicles, check for any corrosion starting around the pivot point or mounting holes. Reject any hinge that is bent, cracked, or shows signs of being stressed past its limits.

Cost Comparison: New vs. Used Aviator Tailgate Hinges

Pricing can vary based on supplier and condition. The lack of aftermarket options makes used OEM parts a particularly good value.

Tailgate Hinge Replacement Overview

Replacing a tailgate hinge on a Lincoln Aviator is a moderately difficult job that requires precision and a helper.

• Difficulty: 4 out of 5
• Time: 2-3 hours
• Tools: Socket set, torque wrench, trim removal tools.

The general process involves:

1. Securely supporting the tailgate with a helper.
2. Removing interior trim panels to access the hinge bolts and any wiring harnesses.
3. Disconnecting the gas struts and any electrical connectors for the power liftgate, camera, or lights.
4. Carefully unbolting the old hinge(s) from the body and the tailgate.
5. Bolting the new hinge(s) in place, leaving the bolts slightly loose for adjustment.
6. Aligning the tailgate to ensure even gaps all around, then tightening the bolts to the factory torque specification. The spec for the similar MKC is 55 Nm (41 lb-ft), which can be used as a reference.
7. Reconnecting all components and performing a power liftgate initialization procedure if required by the service manual.
