NHTSA Complaint #11481965 — 2017 CHRYSLER PACIFICA

The 2017 Pacifica will sometimes have a lack of power when trying to accelerate, and/or will jerk or shutter. Other times, mainly when the engine is warm, it will shutter and die when starting the engine. Sometimes it will take two or three restart attempts for the engine to remain running. In one instance in slow moving stop and go traffic the vehicle stuttered and then accelerated toward the car in front and I had to slam on the brakes to prevent a collision. The vehicle has been back at the dealer multiple times and they claim there are not any codes they can use to diagnose the problem. Even when the engine dies it does not cause the check engine light to come on. When they scan the codes they usually find P0171 and P0174, but they say the codes are not active, only stored. I am told the vehicle is current on all power train software but the problem is still occurring almost daily.
