What is wrong

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

The risk

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.

Why power train defects matter: A power train defect can cause a loss of drive power, an unexpected gear change, or a vehicle that rolls after being put in Park.

The 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.

About the power train

The power train carries engine power to the wheels; the gear selector and Park mechanism are part of it.

What to do

  1. Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
  2. Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-417 and the manufacturer’s number 26S50.
  3. Always set the parking brake when you park until the repair is done, and confirm the vehicle is actually in Park.
  4. Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.

Check by VIN

A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.

Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.

Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
