7 Lincoln MKX Liftgate Problems (Troubleshooting Guide)

If you’re experiencing liftgate issues with your Lincoln MKX, it’s a common problem among many owners. Problems like the liftgate not functioning correctly, becoming unresponsive, or reversing unexpectedly can be inconvenient, especially when you count on its ease of use.

The good news is that practical solutions are available—whether sensor adjustments, motor replacements, or recalibration. Let’s explore the potential causes and how to restore your liftgate’s smooth operation.

1. Liftgate Fails to Open or Close Properly

Owners of 2016-2018 Lincoln MKX models frequently report problems with the power liftgate not opening or closing all the way. It might stop halfway or fail to activate altogether, making access to the rear cargo area difficult.

Faulty sensors, a weak motor, or electrical issues are common culprits. The sensors that detect obstacles can malfunction or get misaligned, causing the system to stop the liftgate prematurely.

Over time, the motor may weaken, especially in vehicles exposed to heavy use or harsh weather. Electrical problems, such as faulty wiring or a malfunctioning control module, can also disrupt liftgate operation.

Realigning or replacing malfunctioning sensors is often the first step in fixing these issues. If the motor is too weak, replacing it can restore full liftgate functionality. Checking wiring and electrical connections is crucial in resolving any related issues.

2. Unresponsive Liftgate Button

In some Lincoln MKX models, particularly from 2017 and 2018, owners have experienced unresponsiveness from the liftgate button—whether on the key fob, the dashboard, or the liftgate itself.

This unresponsiveness can be traced to a faulty control module, which may prevent the liftgate from receiving commands. Another possible cause is a weak battery, as insufficient power can stop the liftgate from functioning. Sometimes, the button itself might be defective.

Reprogramming or replacing the control module usually resolves the issue. Checking the vehicle’s battery for adequate charge and replacing it if needed can ensure proper liftgate operation. If the button itself is faulty, replacing it is the best solution.

3. Liftgate Reverses Direction Unexpectedly

Some Lincoln MKX owners, particularly those with 2016-2019 models, report their liftgate reversing direction. This means it starts to open or close but suddenly stops and goes the other way.

This issue is often caused by the sensors incorrectly detecting an obstacle. If the sensors are dirty or misaligned, they may trigger the system to reverse the liftgate’s motion. Occasionally, a software glitch in the control system can cause similar behavior.

Cleaning and realigning the sensors usually fixes the problem. If not, a dealership might need to perform a software update to correct any glitches in the control system.

4. Liftgate Closes Too Forcefully

Some owners, particularly those with 2015-2018 models, have noticed that the liftgate closes excessively, raising safety concerns for children, pets, or anyone nearby.

This issue typically results from improper calibration of the liftgate’s motor. If the motor is calibrated incorrectly, it may apply too much force. Worn or weak gas struts can also contribute, as they fail to balance the liftgate’s weight, causing the motor to overcompensate.

To fix this, the dealership can recalibrate the motor’s closing force, ensuring it operates at a safer speed. Replacing worn gas struts can also help balance the liftgate and reduce the closing force.

5. Liftgate Beeping but Not Moving

In some 2018-2020 models, owners report the liftgate beeping but not opening or closing. This is often triggered by the safety obstruction mode, where the system mistakenly believes something is blocking the liftgate. A faulty control module or sensor can also be at fault.

Resetting the system by disconnecting and reconnecting the battery can resolve this problem. It’s also worth checking for any real obstructions and ensuring the area around the liftgate is clear.

6. Problems with Hands-Free Liftgate Activation

Some owners have also been upset by the hands-free liftgate feature available in 2017-2019 Lincoln MKX models. The liftgate, which should open with a kick motion under the rear bumper, doesn’t always respond reliably.

The problem is often due to sensor positioning. Aftermarket accessories like tow hitches can interfere with the sensor’s ability to detect the kick motion. In some cases, the issue might be user error, as the hands-free system requires a specific activation motion.

Practicing the correct kick motion can improve the system’s reliability. If the issue persists, the dealership may need to adjust or recalibrate the sensor.

7. Liftgate Fails to Latch Securely

Some owners have encountered problems with the liftgate not latching properly in models from 2016 and 2017, leaving it unsecured while driving or causing a dashboard warning.

A misaligned latch mechanism usually causes this issue. If the latch isn’t correctly aligned, it won’t catch and secure the liftgate. Worn or damaged internal components of the latch can also prevent proper operation.

A professional can realign the latch or replace worn components to ensure the liftgate latches securely every time.

Conclusion

Liftgate problems in the Lincoln MKX, such as incomplete opening or closing, unresponsiveness, or unexpected reversals, are common.

Faulty sensors, motor malfunctions, or software glitches often cause these issues. Thankfully, many of these problems can be resolved with sensor adjustments, part replacements, or software updates, ensuring the liftgate functions smoothly and reliably.
