Solution

1. Preparation

Gather tools: socket set, screwdriver, multimeter, cleaning cloth.
Ensure the vehicle is parked on a level surface and the trunk is empty.
Disconnect the vehicle battery to prevent any electrical issues while working.

2. Inspect and Clean the Latch

Sub-steps:
- Locate the trunk latch assembly.
- Use a cleaning cloth to remove dirt and debris from the latch area.
- Apply lubricant to the latch mechanism to ensure smooth operation.

3. Adjust the Trunk Alignment

Sub-steps:
- Open the trunk and inspect the hinge alignment.
- Loosen the bolts securing the trunk hinges slightly (do not remove).
- Adjust the trunk position until it sits flush with the vehicle body.
- Tighten the hinge bolts to the manufacturer’s specified torque value (consult repair manual for specifics).

4. Inspect and Replace Struts (if necessary)

Sub-steps:
- Remove the trunk struts by detaching them from their mounting points (may require a clip removal tool).
- Compare the old struts with new ones to ensure proper size.
- Install the new struts by reversing the removal process, ensuring they are securely attached.

5. Test Latch Functionality

Sub-steps:
- Close the trunk and listen for the latch to engage.
- Test the trunk by attempting to pull it open after closing to ensure it remains secure.
