Charge Port Latch

Replace the charge port latch assembly on a 2024 Tesla Cybertruck. The latch mechanism is integrated into the charge port housing on the driver-side rear quarter and is responsible for locking/releasing the charging connector during AC/DC charging.

Tools required

Parts

• Charge port latch / actuator assembly (Cybertruck-specific) × 1 — OEM Cybertruck charge port latch — refer to Tesla EPC

Preparation

1. Park on level ground, place in P, engage the parking brake.
2. Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the 48V low-voltage battery (Cybertruck-specific — NOT 12V). Locate the 48V battery per Tesla service documentation and isolate per OEM procedure.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal on this 800V platform.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Ensure no charging cable is plugged into the charge port. Confirm charge port door is in the closed/unpowered state.
7. Cover the rear driver-side stainless panel and tailgate edge with a soft blanket to prevent scratching during work.
8. Allow the charge port area to cool fully if the vehicle was recently DC fast-charged.

Procedure

1. 1

   Access the charge port area
   Open the charge port door manually using the touchscreen command before disconnecting the 48V battery, OR use the manual emergency release cable accessed from inside the rear quarter trim if the door cannot be opened electrically. Confirm the door stays open for the duration of the service.
   ⚠If the latch is already failed and the connector is stuck plugged in, follow the manufacturer-specified manual release procedure before any disassembly.
2. 2

   Remove interior trim to access the charge port housing
   From inside the rear cab/bed wall on the driver side, remove the manufacturer-specified interior trim panel covering the back of the charge port assembly. Use plastic trim tools to release clips. Set fasteners aside in labeled order.
3. 3

   Disconnect low-voltage and signal connectors
   At the rear of the charge port assembly, disconnect the low-voltage signal harness for the latch actuator, charge port LED ring, proximity/CP-PP signal lines, and temperature sensors. Press the connector locking tabs — do not pull on wires. Photograph routing before disconnecting.
   ⚠Do NOT disconnect the orange HV connectors at the back of the charge port. They should remain undisturbed for a latch-only replacement. If HV must be separated, STOP — this is outside this procedure's scope.

   Remove the charge port assembly mounting fasteners
   Remove the fasteners securing the charge port housing to the body bracket. Support the assembly with one hand as the last fastener is removed. Carefully maneuver the housing inward enough to access the latch mechanism without straining the orange HV cables behind it.
   ⚠️Do not let the assembly hang by the orange HV cables. Support it with a strap or assistant.

5. 5

   Identify and remove the latch assembly
   Locate the latch/actuator module on the charge port housing. Release any retaining clips and remove the manufacturer-specified fasteners securing the latch to the housing. Disconnect the latch's dedicated electrical pigtail if not already disconnected. Remove the latch assembly.

6. 6

   Inspect housing and seals
   Inspect the charge port housing for cracks, melted plastic (a sign of past DC fast-charge overheating), corrosion on signal pins, and condition of the perimeter weather seal. Replace seal if compressed or damaged. Clean any debris from the latch pocket.
   ℹ️Discoloration or melting on HV pins is a serious finding — do NOT proceed. Have the vehicle inspected by a Tesla-certified technician.
7. 7

   Install the new latch assembly
   Position the new latch into the charge port housing, ensuring the actuator pawl aligns with the connector retention slot. Install fasteners and torque to OEM specification. Reconnect the latch electrical pigtail until it clicks fully home.

8. 8

   Reinstall the charge port housing
   Carefully route the harness back into position, ensuring no pinch points against the stainless exoskeleton edges. Seat the housing into the body bracket and install the mounting fasteners. Torque to specification.

   Reconnect signal/low-voltage harnesses
   Reconnect every low-voltage and signal connector removed in Step 3. Confirm each locking tab clicks fully. Verify harness routing matches your pre-disassembly photos to prevent chafing.

Reassembly

1. Reinstall the interior trim panel and any clips removed for access.
2. Verify no tools, fasteners, or debris remain in the charge port cavity.
3. Reconnect the 48V low-voltage battery per Tesla-specified procedure.
4. Close all doors and allow the vehicle to fully wake; allow 2-3 minutes for system self-checks.

Verification

• From the touchscreen, command the charge port door OPEN — verify smooth actuation.
• Plug in a Level 1 or Level 2 (AC) charging connector. Verify the latch audibly engages and the connector cannot be pulled out without a touchscreen/app release command.
• Initiate a charging session for at least 60 seconds and confirm normal charging current with no fault messages on the touchscreen.
• Press the charging cable release button on the connector and on the touchscreen — verify the latch releases on each method.
• If available, attempt a DC fast-charge session at a Supercharger to verify latch retention under high current. Monitor for any 'Charge Port Latch' or 'Unable to Charge' alerts.
• Cycle the charge port door closed/open from the app to confirm remote operation.
• Note: This job does not affect any Tesla-recommended service intervals (brake fluid 2 yr, cabin filter 2 yr, drive unit fluid ~12,500 mi initial / 25-50k mi after, coolant inspection 4 yr / 50k mi). Continue those on their normal schedule.
