Five replacement batteries are recalled separately from the factory units that equip the aforementioned 32,125 vehicles. The automaker lists Samsung SDI America Inc. as the supplier, along with production dates ranging from September 18, 2020 to March 22, 2023 for the Wrangler 4xe. As for the replacement packs, make that July 26, 2021 to March 15, 2022.
One mystery, however, still remains. The defect hasn't been identified yet, and Stellantis hasn't determined the root cause either. The automaker that was previously known as Chrysler also highlights that Wrangler 4xe batteries may fail internally, therefore increasing the risk of a thermal event.
Customers are urged to park outside and away from buildings and other vehicles, for the company is aware of eight vehicle fires that occurred with said vehicles parked and turned off. Six of them were connected to chargers when the battery fires occurred. It's not known whether the plug-in hybrid Wrangler 4xe off-road SUVs in question were charging or not.
Until service techs determine whether the battery needs to be replaced or not, owners should refrain from recharging the Wrangler 4xe. Dealers will be notified on January 11, 2024 at the latest, the day owners will also be notified via first-class mail.
What is especially curious about this concern is that affected vehicles were produced through March 22 of 2023. More curious still, Stellantis understands that battery cells manufactured by Samsung SDI from January 21, 2021 to October 2, 2021 are also suspect. What actually happened after October 2, 2021 at the supplier's battery cell assembly plant? Why are battery cells produced after October 2, 2021 completely fine? Unfortunately, we don't have answers to those questions at the moment of reporting.
