REASON FOR THIS SAFETY RECALL

In some of the affected vehicles, the Rear Drive Unit (RDU) may have been produced with a low volume of lubricating oil. If an RDU has low lubricating oil it is possible for the unit to seize, which could result in a loss of mobility and potential loss of vehicle control, increasing the risk of a crash.

 

SERVICE ACTION

Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to inspect the RDU fluid level and replace the RDU if required. This service must be performed on all affected vehicles at no charge to the vehicle owner.

 

OWNER NOTIFICATION AND MAILING SCHEDULE

Owner letters were mailed the week of March 8, 2021. Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.

PLEASE NOTE:

Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $21,000 per vehicle. Correct all vehicles in your new vehicle inventory before delivery.

    • If NO – Vehicle PASSES inspection. Proceed to Step 3 for fluid level check.

 

3. Locally obtain a wire coat hanger. Fabricate a rear differential fluid level dip stick. See Figure 1.

 

  • For Edge and Nautilus vehicles: Horizontal distance of 36mm (1.4 in), Vertical distance of 6mm (0.24 in).

 

  • For Escape, Corsair, Kuga, and Bronco Sport vehicles: Horizontal distance of 32mm (1.3 in), Vertical distance of 3mm (0.12 in).
