Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues while working with the latch mechanism.

2. Clean the Latch Mechanism

Tools Required: Cleaning brush, lubricant spray.
Remove any debris from the trunk latch area using a cleaning brush.
Apply a lubricant spray to the latch mechanism to ensure smooth operation.

3. Adjust the Trunk Alignment

Tools Required: Socket set, torque wrench.
Loosen the bolts on the trunk hinges slightly using a socket set.
Adjust the trunk lid's position until it aligns properly with the vehicle body.
Tighten the bolts to the manufacturer's specified torque settings (typically around 7-10 Nm, but consult the service manual for exact values).

4. Test the Latch Actuator

Tools Required: Multimeter.
Reconnect the battery and use a multimeter to test the voltage at the trunk latch actuator while pressing the trunk release button.
If the voltage is not within specifications, replace the latch actuator.

5. Inspect and Replace the Trunk Seal (if necessary)

Parts Required: Replacement trunk seal.
Inspect the trunk seal for any signs of damage or wear.
If damaged, remove the old seal and install a new one, ensuring it fits snugly around the trunk opening.
