The ecu/pcu has developed a failure to control the idle air intake valve due to an unrepairable defect on the computer. It can shut the engine down without warning while running, especially when approaching stops. It requires the operator to try to control the issue using the accelerator pedal to override it and prevent the engine from cutting out. It can happen without warning, and DE[pending on the skill level of the driver, an accident can easily result. Plus there are no repair parts for the ecu/pcu in the parts system, resulting in an unsafe and unmaintainable vehicle on the highways. The ecu /pcu was used one year only, so the Chrysler engineers knew they had a defect. No older Jeep used this particular unit and no younger ones used it either!.
