October 22, 2018 through September 27,

2021June 4, 2020 through November 10, 2021
2022June 29, 2021 through April 26, 2022

Affected vehicles are identified in OASIS.

Note: This program does NOT cover Explorer Police Units (VIN Positions 5-7 are K8A). These vehicles are covered under Recall 22S27.

 

REASON FOR PROVIDING A NO-COST, ONE-TIME REPAIR

In some of the affected vehicles, the rear axle mounting bolt may fracture during vehicle acceleration. A fractured rear axle bolt will allow the rear axle housing to move out of position, resulting in severe noise and vibration. If the rear axle bolt breaks, the driveshaft/half shafts may become disconnected, resulting in loss of transmission torque to the rear wheels which is necessary to hold the vehicle in park.

 

SERVICE ACTION

If an affected vehicle exhibits a fractured rear axle bolt, dealers are to replace the rear axle bolt, rear differential cover, and subframe bushing. This service must be performed at no charge to the vehicle owner.

 

OWNER NOTIFICATION AND MAILING SCHEDULE

An initial Owner Letter was mailed the week of June 6, 2022 notifying the owner about this program.

An additional Owner Letter will be combined with 22S27 and mailed when parts are available in sufficient quantities.

 

SOLD VEHICLES

  • Only owners with affected vehicles that exhibit the covered condition will be directed to dealers for repairs.
  • Dealers are to prioritize repairs of customer vehicles over repairs of new and used vehicle inventory.

 

STOCK VEHICLES

  • Do not perform this program unless the affected vehicle exhibits the covered condition.

 

TITLE BRANDED / SALVAGED VEHICLES

Vehicles with cancelled warranties are not eligible for this service action.

 

OWNER REFUNDS

  • FordeBay logo Motor Company is offering a refund for owner-paid repairs covered by this program if the repair was performed before the date of the Owner Notification Letter. This refund offer expires March 31, 2023.
  • Dealers are also pre-approved to refund owner-paid emergency repairs that were performed away from an authorized servicing dealer after the date of the Owner Notification Letter. Noncovered repairs, or those judged by FordeBay logo to be excessive, will not be reimbursed.
  • Refunds will only be provided for the cost associated with rear axle bolt fracture.

 

RENTAL VEHICLES  

The use of rental vehicles is not approved for this program.

 

TOWING

If towing is required, dealers are authorized to claim up to a maximum value of $250 to provide towing services for this program.

Summary

Certain 2020-2022 Model Year Explorer (Non-Police) Vehicles – Rear Axle Repair After Bolt Fracture. In some of the affected vehicles, the rear axle mounting bolt may fracture during vehicle acceleration. A fractured rear axle bolt will allow the rear axle housing to move out of position, resulting in severe noise and vibration. If the rear axle bolt breaks, the driveshaft/half shafts may become disconnected, resulting in loss of transmission torque to the rear wheels which is necessary to hold the vehicle in park. If the parking brake is not applied, the loss of the primary park torque will allow the vehicle to roll in park increasing the risk of crash and injury.
