Rattling from the rear hatch is often due to loose hatch bolts. Here's a step-by-step solution:

1. Inspect the Bolts: Open the rear hatch and locate the bolts on either side.
2. Tighten the Bolts: Use a wrench to ensure all bolts are securely tightened. If they are loose, tighten them to the proper torque specification.
3. Use Loctite: Apply a small amount of thread locker (like Loctite) to the bolts to prevent them from loosening over time.
4. Test for Noise: Close the hatch and take the car for a test drive to ensure the rattling noise is gone.
