NHTSA Complaint #11713635 — 2022 CHRYSLER PACIFICA

The vehicle experienced a failure of the hybrid battery thermal management system. A diagnostic trouble code (P0E15 – Hybrid/EV Battery Pack Coolant Heater “A” Control Performance) was set and the check engine light illuminated. This component is responsible for regulating high-voltage battery temperature and is part of the hybrid cooling/heating system required for safe operation and emissions readiness. The failure occurred at approximately 100,700 miles on a 2022 Chrysler Pacifica Hybrid. The battery coolant heater is a sealed, high-voltage electronic component with no maintenance or wear interval and is not a consumable part. Loss of proper battery temperature control can affect hybrid system operation, charging, regenerative braking, and power availability, and can potentially result in reduced power or limp-mode operation as the vehicle attempts to protect the high-voltage battery and inverter. The problem was confirmed by a Chrysler dealership and an Area Service Manager using factory diagnostic equipment. The fault code is stored and permanent. The vehicle was inspected by the dealer, and the component was diagnosed as failed and requiring replacement. No accident, misuse, or maintenance neglect was involved. The manufacturer declined warranty or goodwill coverage based on internal policy, despite the failure occurring immediately beyond the hybrid warranty mileage threshold and involving a non-wear, safety-critical hybrid thermal management component. The repair estimate is approximately $1,900 out of pocket. The warning indicator (check engine light) first appeared at the time of failure. The component remains available for inspection and replacement by the dealer. Also the dealership did not provide is with a written justification for the denial and corporate (Stellantis) stated that they were not able to provide justification either other than what the automated prompt was giving them (that the part was not covered under goodwill)
