FCA Blames Wiring Harness Problem on ZF Transmission’s Sudden Loss of Propulsion

A transmission defect known to cause a sudden loss of propulsion is being recalled in over 400,000 Fiat-Chrysler (FCA) vehicles.

[FCA] was examining warranty data and opened an investigation that determined an insufficient crimp in a wire harness could cause a fault code in the solenoid. If that occurs, the vehicle will stop moving, something Chrysler says can temporally be fixed by stopping the vehicle and re-starting the engine.

The problem affects vehicles with a 9-speed ZF transmission (number 9HP48 or 948TE), this includes the 2015 Jeep Cherokee and Renegade, as well as the Chrysler 200, and Ram ProMaster City. FCA says certain 2014 Cherokees will be included as well. All affected vehicles were built before September 23rd, 2014.
