Tools required

Parts

• Charge port latch assembly × 1 — Use OEM specification
• Trim panel retaining clips (if damaged) × 5 — Use OEM specification

Preparation

1. Ensure vehicle is parked on level ground with parking brake engaged
2. Verify no charging cable is connected to the vehicle
3. Open the charge port door fully
4. Locate the 12V battery access panel on driver side near the cab
5. Disconnect the negative terminal of the 12V battery and wait at least 5 minutes before proceeding
6. Gather all necessary tools and the replacement charge port latch assembly

Procedure

1. 1

   Access the charge port area
   Open the cargo area rear door. The charge port is located on the driver side rear quarter panel. Use plastic trim tools to carefully release the interior cargo panel clips adjacent to the charge port. Remove the panel to expose the backside of the charge port assembly.
2. 2

   Remove charge port access cover
   From inside the cargo area, locate the charge port access cover secured with T20 Torx screws. Remove the four screws securing the access cover and carefully set the cover aside. You should now have clear access to the rear of the charge port assembly and latch mechanism.
3. 3

   Disconnect electrical connectors
   Locate the electrical connector for the charge port latch mechanism. Press the locking tab and carefully disconnect the main harness connector. If present, disconnect the secondary position lock connector. Note the routing of the wiring harness for reinstallation.
4. 4

   Remove latch mounting fasteners
   Using a T25 Torx driver, remove the two screws securing the latch assembly to the charge port housing. Support the latch mechanism while removing the final fastener to prevent it from dropping.
5. 5

   Release latch from actuator linkage
   Carefully observe how the latch mechanism connects to the charge port door actuator linkage. Press the linkage release tab and gently rotate the latch assembly to disengage it from the actuator arm. Remove the old latch assembly from the vehicle.
6. 6

   Prepare new latch assembly
   Unpack the new charge port latch assembly and verify it matches the original part. Check that the latch mechanism moves freely and the mounting points align properly. Compare with the old unit to ensure correct part.
7. 7

   Install new latch to actuator linkage
   Position the new latch assembly and align it with the charge port door actuator linkage. Engage the linkage arm into the latch mechanism until you hear or feel a positive click, confirming it is properly seated.
8. 8

   Secure latch mounting fasteners
   Align the latch assembly mounting holes with the charge port housing. Install the two T25 Torx mounting screws and tighten them evenly in a cross pattern. Ensure the latch is seated flush against the housing with no gaps.
9. 9

   Reconnect electrical connectors
   Route the wiring harness according to your reference photos. Connect the main electrical connector to the charge port latch, ensuring it clicks fully into place. If equipped, install the secondary position lock. Verify connectors are secure by gently tugging on them.
10. 10

    Reinstall access cover and trim
    Position the charge port access cover and install the four T20 Torx screws. Reinstall the interior cargo panel, ensuring all retaining clips are properly aligned and fully seated. Replace any damaged clips with new ones.
11. 11

    Reconnect 12V battery
    Return to the 12V battery location. Reconnect the negative battery terminal and ensure it is secure. The vehicle may need a few moments to complete system initialization.
12. 12

    Test latch operation
    Close the charge port door and verify it latches securely. Use the vehicle controls or mobile app to open and close the charge port door multiple times, listening for proper latch engagement. The door should close firmly with an audible click and should not rattle or feel loose.

Reassembly

1. Ensure all trim panels are fully seated with clips engaged before closing cargo doors
2. Verify no tools or parts were left in the charge port area
3. Confirm all electrical connectors are fully seated and locked
4. Check that the charge port door opens and closes smoothly without binding

Verification

• Test charge port door operation from vehicle touchscreen or mobile app at least 5 times to ensure consistent latching
• Visually inspect that the charge port door sits flush with the body panel when closed
• Attempt to gently pull the charge port door open when latched - it should remain securely closed
• Connect a charging cable to verify the latch releases properly when a charging session is initiated
• Check for any error messages or warning lights related to the charge port on the vehicle display
• Verify the charge port light illuminates properly when the door is opened
