Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed.

POWER TRAIN:AUTOMATIC TRANSMISSION

Campaign: 18V100000 Date: 08/02/2018

Chrysler (FCA US LLC) is recalling certain 2017-2018 RAM 1500, 2500, 3500, 3500 Cab Chassis, 4500 Cab Chassis, and 5500 Cab Chassis vehicles, all equipped with a column shifter.

Consequence

Being able to shift the transmission without pushing the brake pedal and/or without a key in the ignition can increase the risk of an unintended vehicle rollaway that may result in personal injury or a crash.

The recall began February 26, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U11.
