NHTSA Complaint #11671077 — 2018 CHRYSLER PACIFICA

After the 73B recall was performed on my 2018 Chrysler Pacifica Hybrid, the vehicle began experiencing persistent check engine lights and charging issues, especially during charging. Diagnostic scans revealed codes U0412 (invalid data from battery energy control module) and P0BBE (hybrid battery pack voltage variation), both directly related to the high-voltage battery system. These issues began within days of the recall and escalated, with the battery fault becoming permanent by late May 2025. The recall was issued due to a risk of fire from the high-voltage battery, caused by defects that can develop over time. The recall remedy included a software update to monitor for dangerous battery conditions and disable charging if a risk is detected, as well as inspection and replacement of the battery if necessary. My vehicle’s post-recall symptoms—persistent warning lights and charging faults—are exactly the type of problems the recall is meant to detect. The problem was confirmed by diagnostic data and scan reports, which were sent from the dealer to Chrysler’s technical support (STAR), but the vehicle itself was not physically inspected by the dealer or STAR. Both refused to authorize battery replacement, citing the contradicting STAR report, despite clear evidence of battery failure and the recall’s stated purpose. The battery and related components are available for inspection upon request. My safety and my family’s safety are put at risk, as the recall specifically warns owners not to charge or park the vehicle near structures until the remedy is complete, due to fire risk. Multiple other owners have reported similar post-recall battery failures, indicating a broader unresolved safety issue. Chrysler has not provided a satisfactory resolution, and the vehicle continues to exhibit battery faults and charging issues after the recall remedy.
