This procedure replaces the trunk/liftgate actuator on a 2016-2024 Hyundai Tucson, which controls the power liftgate locking mechanism.

Warnings

Tools required

Parts

• Liftgate lock actuator assembly × 1 — 81230-D3000 or equivalent OEM
• Trim panel retaining clips (if damaged) × 5 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn off ignition and remove key/fob from vehicle interior
3. Open liftgate and prop securely in fully open position
4. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge
5. Gather all tools and new actuator assembly within reach of liftgate area

Procedure

1. 1

   Remove lower liftgate trim panel
   Using trim panel removal tools, carefully pry off the lower interior trim panel on the liftgate. Start at the edges and work around the perimeter. There are typically 8-10 plastic retaining clips. Pull the panel away gently to avoid breaking clips. Set panel aside on a protected surface.
2. 2

   Remove upper liftgate trim panel
   Locate and remove the upper trim panel by releasing the retaining clips along the top edge of the liftgate. On models with power liftgate, disconnect the courtesy light electrical connector by pressing the tab and pulling straight out. Set upper trim panel aside.
3. 3

   Locate the liftgate actuator assembly
   With trim panels removed, locate the liftgate lock actuator on the driver's side (left) of the liftgate latch mechanism. It is a black plastic assembly approximately 4 inches long with an electrical connector and mechanical linkage rod attached.
4. 4

   Disconnect actuator electrical connector
   Locate the electrical connector attached to the actuator. Press the locking tab (typically red or gray) and pull the connector straight out from the actuator. Do not pull on the wires themselves. Inspect connector pins for corrosion or damage.
5. 5

   Disconnect actuator linkage rod
   The actuator has a white or black plastic linkage rod connecting it to the latch mechanism. Carefully pry the rod end clip off using a small flathead screwdriver or trim tool. Once the clip is removed, slide the rod off the ball joint. Note the orientation for reinstallation.
6. 6

   Remove actuator mounting bolts
   Using a 10mm socket, remove the two or three mounting bolts securing the actuator to the liftgate inner structure. Keep these bolts as they will be reused with the new actuator.
   Torque spec

   Module Mounting Bolts8 Nm (6 lb-ft)
7. 7

   Remove old actuator
   Carefully pull the actuator assembly away from the mounting surface. Maneuver it out through the access area in the liftgate structure. Inspect the mounting area for any debris or corrosion and clean if necessary.
8. 8

   Install new actuator assembly
   Position the new actuator in the same orientation as the old unit. Align the mounting holes with the threaded bosses in the liftgate structure. Start all mounting bolts by hand before tightening to ensure proper alignment.

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Reconnect actuator linkage rod
   Attach the linkage rod to the new actuator's ball joint. Ensure the rod snaps fully onto the ball joint, then install the retaining clip. Tug gently on the rod to verify it is securely attached and moves freely without binding.
10. 10

    Reconnect electrical connector
    Push the electrical connector onto the new actuator until you hear/feel a positive click. Gently tug on the connector to ensure it is fully locked. Verify that the locking tab has engaged properly.
11. 11

    Reinstall trim panels
    Reconnect the courtesy light connector if applicable. Position the upper trim panel and press firmly around all clip locations until each clip snaps into place. Repeat for the lower trim panel. Ensure all clips are fully seated and panels are flush with the liftgate.
12. 12

    Reconnect battery and initialize system
    Reconnect the negative battery terminal. Close the liftgate gently. Turn ignition to ON position (engine off). Lock and unlock the vehicle using the key fob multiple times to allow the actuator to cycle and initialize. Listen for proper actuator operation with each lock/unlock cycle.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all trim panels are properly secured with no gaps or loose areas
2. Verify all electrical connectors are fully engaged and locked
3. Confirm linkage rod is properly clipped and moves without binding
4. Reset power window auto-up/down functions if necessary (hold window switch up for 3 seconds after full close)

Verification

• With vehicle locked, press the liftgate unlock button on key fob - you should hear the actuator operate and liftgate should unlock
• Open and close the liftgate manually several times, locking and unlocking between cycles to verify consistent operation
• Verify the liftgate remains securely latched when closed and locked - it should not open with moderate upward pressure
• Test the interior liftgate release button to ensure it properly unlocks the liftgate
• On models with power liftgate, test automatic open/close functions to ensure the actuator does not interfere with operation
• Drive the vehicle and verify the liftgate remains securely closed over bumps and during acceleration/braking
• Check for any warning lights on the instrument cluster related to liftgate or security systems
