NHTSA Complaint #11677247 — 2018 CHRYSLER PACIFICA

After safety recall 73B was performed on my 2018 Chrysler Pacifica Hybrid on 02/03/2025, the vehicle's check engine light illuminated and it began experiencing charging failures. The component that has failed is the high-voltage (HV) battery pack and its control system. Diagnostic scans performed by a Chrysler dealer on [Date of diagnosis] confirmed trouble codes, including U0412, which indicate a critical fault within the battery system. The HV battery is available for inspection upon request. My safety and the safety of others are at risk because the recall was issued to prevent a battery fire. The symptoms my vehicle is exhibiting are precisely the kinds of faults the recall's software update is supposed to detect. By refusing to provide the full remedy, the manufacturer has left an unresolved fire hazard. The problem was confirmed by dealer diagnostic reports. However, both the dealer and Chrysler have refused to replace the defective battery under the recall. Their denial is based on [indicate reason for denial]. The first warning signs, including the check engine light, appeared within days of the recall service. This strongly indicates the recall procedure, specifically the mandatory battery integrity test, was not completed correctly by the dealership. This is a widespread issue, with numerous owners reporting the same post-recall failures online and to Chrysler Cares customer service.
