NHTSA campaign 20V183000
Hazard
Chrysler (FCA US LLC) is recalling certain 2019 Jeep Grand Cherokee and Dodge Durango vehicles. The front differential may have been assembled with pinion gears that are insufficiently hardened, which can lead to the gear teeth wearing down. If both pinion gears have their teeth sufficiently worn off, torque power can not be transferred from the front wheels to the driveline, resulting in loss of power while driving and loss of the PARK function when stationary.
Consequence
A sudden loss of power while driving or loss of the transmission PARK function can increase the risk of a crash.
Remedy
Chrysler will notify owners, and dealers will replace the front differential, free of charge. The recall began May 21, 2020. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is W22.
