Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery if electrical components are affected.

2. Inspect and Repair the Trunk Seal

Sub-steps:
1. Remove any trim or coverings obstructing the trunk seal.
2. Carefully inspect the rubber trunk seal for cracks or tears.
3. If damaged, remove the old seal by pulling it off carefully.
4. Clean the surface of the trunk where the seal attaches.
5. Apply a new trunk seal (OEM recommended) by pressing it into place, ensuring a snug fit.

Tools Required:

Trim removal tool
Utility knife (if cutting old seal)
Adhesive (if necessary for seal installation)

3. Clear Blocked Drainage Holes

Sub-steps:
1. Locate the drainage holes in the trunk area, typically found near the rear tail lights or under the spare tire compartment.
2. Use a small wire or compressed air to clear any debris blocking the holes.
3. Test the drainage by pouring a small amount of water into the area to ensure it flows properly.

4. Inspect and Reseal Tail Light Assemblies

Sub-steps:
1. Remove the tail light assemblies by unscrewing the retaining bolts.
2. Inspect the gasket around the tail light for any damage.
3. Apply a silicone sealant around the edges if the gasket is compromised.
4. Reinstall the tail light assembly and ensure it is tightly secured.

5. Check Rear Hatch Alignment

Sub-steps:
1. Visually inspect the rear hatch alignment with the body of the vehicle.
2. Adjust the hinges if the hatch is misaligned, which may cause improper sealing.
3. Test the hatch closure to ensure even pressure along the seal.
