Prepare your observation

Keep existing warnings or observations for service. This guide does not ask you to probe wiring, disconnect a battery or open a high-voltage assembly.

A reported defect describes the campaign. It does not establish what caused a symptom on your individual vehicle, and absence of a symptom does not establish that an open recall is complete.

The reported manufacturer remedy

Dealers will replace the two-part wiring harness and connector, free of charge. Interim letters, notifying owners of the safety risk, were mailed August 9, 2024. A second notice will be sent once the final remedy is available. Owners may contact MBUSA customer service at 1-877-496-3691. MBUSA's number for this recall is 2024100002/3. This recall supersedes recall 22V-533. Vehicles repaired under the prior recall will still need to have the new remedy performed.

Your campaign-specific service questions

Use these questions with the official report. Keep the answers beside the remedy record; “discussed” records a conversation, not a completed repair.

  1. Does the manufacturer confirm that campaign 24V445000 applies to this VIN, including the report’s equipment and production restrictions?

    A matching model and year is only a starting point. The official lookup or manufacturer must establish the individual vehicle’s status.

  2. The source describes a pending remedy or parts. What is available now for this VIN, and which interim instructions still apply?

    The dated official record describes development, future availability or a later remedy step. It does not establish today’s parts or appointment availability. Confirm the current remedy and any interim instructions with the manufacturer.

  3. Which electrical component or software function is covered, and what interim charging, parking or use instructions does the manufacturer give?

    Compare the answer with the reported component: ELECTRICAL SYSTEM:WIRING.

  4. Which items in the reported replacement remedy for 24V445000 were replaced, and are they identified on the work order?

    Keep the replaced items and the campaign number together so that a later visit can distinguish recall work from other repairs.

  5. How does this campaign relate to 22V533000, and does work recorded under an earlier campaign satisfy the current remedy?

    Show any earlier work order. Related recall numbers can describe expanded or repeated work; ask the manufacturer to reconcile the records.

  6. What dated document records the remedy performed under 24V445000, and what should I do if the reported concern remains?

    Keep campaign completion and unresolved symptoms as separate questions. A saved worksheet or booked appointment does not establish a repair.
