Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a flat surface and engage the parking brake.
  • Ensure the vehicle is powered down and the key fob is away from the vehicle.
2. Inspect the Trunk Release Button
  • Locate the trunk release button on the rear hatch.
  • Remove the button cover using a small flat-head screwdriver if necessary.
  • Check for any debris or damage to the button contacts.
  • Clean contacts with electrical contact cleaner and allow to dry.
3. Check Power Supply to the Latch
  • Remove the interior trim panel from the rear trunk area using a trim removal tool.
  • Locate the trunk latch assembly and its wiring harness.
  • Use a multimeter to check for voltage at the latch connector while pressing the trunk release button.
    • Expected voltage: 12V
  • If no voltage is present, trace back the wiring for breaks or disconnections.
4. Replace the Trunk Latch Assembly (if necessary)
  • If the latch is found to be faulty, remove the screws securing the latch to the trunk lid.
  • Disconnect the wiring harness from the latch.
  • Install the new latch assembly by reversing the removal steps.
  • Torque screws to manufacturer specifications (usually around 5-10 Nm).
5. Reassemble Trunk Components
  • Reinstall the interior trim panel, ensuring all clips are secured.
  • Replace the trunk release button cover.
