Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical issues during repairs.

2. Inspect Trunk Alignment

Open the trunk fully and visually inspect the alignment with the body.
If misaligned, adjust the trunk hinges by loosening the hinge bolts and repositioning the trunk as needed.
Tighten the bolts to the manufacturer's torque specifications (usually around 10-15 ft-lbs).

3. Check and Clean the Trunk Latch

Remove any obstructions around the latch area, such as debris or dirt.
Clean the latch mechanism with a suitable cleaner and lubricate it with a silicone-based lubricant to ensure smooth operation.
Test the latch manually to confirm it engages and releases correctly.

4. Inspect and Repair Trunk Sensor Wiring

Visually inspect the wiring harness connected to the trunk sensor for frayed or damaged wires.
If damaged, replace the affected wiring or connectors.
Ensure that all connections are secure and free of corrosion.

5. Test the Trunk Mechanism

Reconnect the vehicle's battery.
Close the trunk and listen for the latch to engage.
Check for error messages on the dashboard related to the trunk status.
