Engine stall

During PE12-016, Chrysler identified a condition in model year (MY) 2011 Chrysler 200 and Dodge Avenger vehicles equipped with 3.6L engines that may result in engine stall when stopped or travelling at very low speeds.

The complaint counts shown in this resume include incidents in which enough detail was available to verify the symptoms were related to the defect condition identified by Chrysler. Two complaints alleged engine stall resulting in collisions, one involving very minor damage and one involving a single vehicle road departure crash in which the vehicle was totalled. In the first incident, the vehicle stalled while stopped at an intersection and rolled back into a following vehicle resulting in a minor scratch in the rear bumper.

The police report does not include any references to stalling as a cause or contributor, but cites excessive speed entering the turn. Although there was evidence or prior history with stalling when stopped, there is no evidence that engine st
