Toyota Highlander Trunk Won't Close: Troubleshooting Guide

The Toyota Highlander is a popular SUV known for its reliability, but sometimes owners may encounter issues with the power liftgate not closing properly. This guide will help you troubleshoot and resolve the problem.
Common Causes
There are several reasons why your Toyota Highlander's trunk might not close:
- Obstructions: Check for any items blocking the liftgate's path
- Faulty sensors: The liftgate sensors may be malfunctioning
- Disabled power liftgate: The feature might be turned off
- Weak liftgate struts: The supporting struts may need replacement
- Misaligned latch: The liftgate latch could be out of alignment
Troubleshooting Steps
Check for Obstructions
Inspect the liftgate area thoroughly for any objects that might prevent proper closure. Even small items can trigger the safety sensors and cause the liftgate to reopen.
Verify Power Liftgate Settings
Ensure the power liftgate feature is enabled:
- Locate the button inside the glove box
- Make sure it's pressed in (enabled position)
- If it's pushed out, press it to enable the power liftgate function
Reset the Liftgate System
Perform a system reset:
- Open the liftgate manually
- Press and hold the close button on the liftgate for about 5 seconds
- Release when you hear multiple beeps
- Try closing the liftgate using the power function
Inspect Liftgate Struts
Weak or faulty struts can prevent proper closure:
- Open the liftgate and observe if it stays up on its own
- If it slowly closes or feels heavy, the struts likely need replacement
Check Liftgate Alignment
Misalignment can cause closing issues:
- Examine the liftgate's position when closed
- Look for uneven gaps or misalignment with the vehicle body
- If misaligned, professional adjustment may be necessary
When to Seek Professional Help
If these troubleshooting steps don't resolve the issue, it's time to consult a professional:
- Persistent problems: If the liftgate continues to malfunction
- Unusual noises: Grinding or squealing sounds during operation
- Visible damage: Any signs of physical damage to the liftgate or its components
A certified Toyota technician can diagnose and repair more complex issues with the power liftgate system.
Preventive Maintenance
To avoid future liftgate problems:
- Regular cleaning: Keep the liftgate area clean and free of debris
- Gentle operation: Avoid forcing the liftgate open or closed
- Scheduled service: Follow Toyota's recommended maintenance schedule
By following these tips and troubleshooting steps, you can often resolve Toyota Highlander trunk closure issues without the need for professional intervention. However, always prioritize safety and seek expert help if you're unsure about any repair procedures.
