Power Train:automatic Transmission:lever And Linkage:column Shift 2019-04-11 · campaign 19V295000 · 16 vehicles
Defect: Forest River, Inc. (Forest River) is recalling certain 2018 Dynamax Isata vehicles built on a RAM chassis and equipped with a column shifter. Pushing the brake pedal for prolonged periods when the vehicle is running and in PARK may cause the Brake Transmission Shift Interlock (BTSI) pin to stick in the open position. With the pin in the open position, the transmission can be shifted out of PARK into any gear without pushing the brake pedal or having the key in the ignition.
Risk: 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.
Fix: Forest River will notify owners, and Chrysler dealers will update the vehicle software, inspect the BTSI, and, as necessary, replace it, free of charge. The recall began May 6, 2019. Owners may contact Chrysler customer service at 1-800-853-1403 or Forest River at 1-574-262-3474. Forest River's number for this recall is 55-0993.
