Jeep Grand Cherokee Recall 20V183: Front differential may wear out, causing sudden power loss

NHTSA campaign 20V183, reported March 26, 2020, 515 vehicles potentially affected.

What this recall means for you

The front differential in certain vehicles may have been built with pinion gears that are not hardened enough. Over time, the gear teeth can wear down. If both pinion gears wear down far enough, power can no longer be sent from the front wheels to the driveline, which can cause a sudden loss of power while driving and a loss of the PARK function when the vehicle is stopped.

A sudden loss of power or of the park function can increase the risk of a crash. Owners should be aware of this risk and address the recall promptly.

The front differential will be replaced free of charge at an authorized dealer. Owners will be notified by mail, and may also contact Chrysler customer service at 1-800-853-1403 (recall number W22). You can also check your vehicle identification number (VIN) for open recalls.
