NHTSA Complaint #11713758 — 2017 CHRYSLER PACIFICA

After purchasing a used 2017 Chrysler Pacifica from Massey Cadillac of Orlando, a warning light appeared during the initial drive indicating a malfunction in the Auto Start/Stop system (capital letter “A” inside a circle with an exclamation point). The system was disabled and indicated service was required. The vehicle was inspected by an authorized Chrysler dealership, which confirmed that the auxiliary ESS (Engine Stop/Start) battery was missing, not failed. Installation of the auxiliary battery and associated mounting hardware was required, indicating the component was not present in the vehicle at the time of inspection. The auxiliary ESS battery is part of a safety-related system. The servicing dealership advised that operating the vehicle without this battery can result in intermittent loss of power steering assist and potential loss of motive power without warning, increasing the risk of a crash. The condition was confirmed by an authorized dealer and is available for inspection upon request. The warning indicator appeared immediately upon operation of the vehicle following purchase. No collision occurred, but vehicle occupants, including children, were placed at risk due to the missing safety component.
