POWER TRAIN:AUTOMATIC TRANSMISSION01/05/2018

Chrysler (FCA US LLC) is recalling certain 2018 Dodge Charger, Durango and Challenger, Jeep Grand Cherokee and Wrangler, Chrysler 300, and RAM 1500 vehicles. An incorrect transmission park lock rod may have been installed in the transmission.

Risk: If the incorrect park lock rod is installed, the transmission may not shift into 'PARK' and keep the vehicle from moving, increasing the risk of unintended vehicle movement and the risk of a crash.
