According to the National Highway Traffic Safety Administration (NHTSA), the issue arises from a folded or torn anode tab, potentially generating lithium by-product over time. This, combined with an "unidentified factor," could cause an internal battery short, leading to a vehicle fire. This follows a major recall involving Stellantis and the Pacifica last month.
Chrysler has not issued a "Do Not Drive" order but advises owners to park their minivans away from structures and other vehicles and not to recharge them until the issue is resolved. Only 5% of the recalled vehicles are estimated to have the defect.
Chrysler's previous attempt to fix the problem involved a software update to monitor the battery for fire risks and replacing battery packs as needed. Despite this, seven additional fires occurred after the 2022 recall. No accidents or deaths have been linked to the issue, but four injuries have been reported.
The latest solution involves updating the high-voltage battery pack control module (BPCM) software and replacing the battery pack assembly if necessary. These repairs will be free for customers. Owners will be notified by mail on September 6, 2024, and can contact FCA US customer care at 1-800-853-1403. Vehicles repaired under the previous recall will also need the latest fix. Earlier in 2023, 67,118 Pacificas were recalled for potential unexpected engine shutdowns.
