Can stall

The powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition. A vehicle stall can increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the powertrain control module, free of charge.

Cruise control may not switch off

Crash risk

A short in the wiring can keep the cruise control engaged even when you press the brake or turn the system off, so the car may hold its speed or speed up. This raises the risk of a crash, so stop using cruise control until the repair is done.

Fix: The dealer will update the engine or powertrain control software at no charge.
