Solution

1. Preparation

Gather necessary tools and parts.
Ensure that the vehicle is turned off and parked on a level surface.
Disconnect the 12V battery to prevent any electrical issues while working.

2. Inspect and Clean the Trunk Latch

Locate the trunk latch assembly.
Use a soft brush or compressed air to remove any debris or dirt from the latch mechanism.
Wipe down the latch and surrounding areas with a clean cloth.

3. Adjust Trunk Alignment

Open the trunk and examine the alignment of the trunk lid.
If misaligned, loosen the hinge bolts slightly (using a socket set).
Adjust the trunk lid until it is flush with the body of the vehicle.
Tighten the hinge bolts to manufacturer specifications (typically 6-8 ft-lbs).

4. Test and Replace Latch Mechanism (if necessary)

Manually operate the latch to see if it engages and disengages smoothly.
If the latch is sticky or does not operate smoothly, it may need replacement.
Disconnect the wiring harness from the latch and remove the latch assembly using a socket set.
Install the new latch by reversing the removal steps, ensuring proper alignment.
Reconnect the wiring harness.

5. Reconnect Battery

Reconnect the 12V battery after all repairs are complete.
Ensure all connections are secure.
