What the official report says

Ford Motor Company (Ford) is recalling certain 2021-2023 Mustang Mach E vehicles. The rear differential pinion shaft may fracture.

Official NHTSA campaign record

Why the reported issue matters

Differential pinion shaft fracture may result in a loss of drive power, or unintended vehicle movement if the vehicle is in park without the parking brake applied, increasing the risk of a crash.

Official NHTSA campaign record

Prepare your observation

Record an existing symptom and its date. Do not reproduce a loss of power, stall or transmission fault in traffic.

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 repair or replace the rear differential assembly as necessary, free of charge. Interim letters, notifying owners of the safety risk, were mailed July 13, 2026. Additional letters will be sent once the remedy is available, anticipated in late December 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26S50.

The source describes a pending remedy or parts

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.

Timing language in the official record

Additional letters will be sent once the remedy is available, anticipated in late December 2026.

This describes the dated source record. Current arrangements for your VIN remain unconfirmed.

Choose the next step from the official result

Not checked or unavailable

Keep eligibility unconfirmed. Use the official lookup or contact the manufacturer with 26V417000.

This campaign is open

Confirm current interim instructions, remedy availability and service arrangements. Keep the dated answer.

Not listed as open

Review earlier repair records and lookup limits if needed. A zero-open result does not explain an unresolved symptom.

Work order records recall work

Keep the campaign number, remedy and date together. Ask separately about a symptom that remains after the visit.

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 26V417000 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. Will the campaign record state whether the rear differential assembly was repaired or replaced, and what determined that choice?

    The remedy permits repair or replacement as necessary. Keep the actual result rather than treating either action as automatic.

  4. If an existing driveline concern is present, what transport or use instructions apply until Ford provides the remedy?

    Record what was already noticed. Do not perform a road test or work under the vehicle to check the pinion shaft.

  5. Which engine or transmission component is covered, and does an existing drivability problem need separate diagnosis?

    Compare the answer with the reported component: POWER TRAIN:DRIVELINE:DIFFERENTIAL UNIT.

  6. If an inspection determines which work is needed, what was inspected, what was found, and which corrective work followed?

    Ask for the inspection result as well as the final action. A parts list alone may not describe an inspection-based remedy.

  7. Which items in the reported replacement remedy for 26V417000 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.

  8. What dated document records the remedy performed under 26V417000, 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.
