Known issues

High

NHTSA 25V-741 (October 2025) covers certain 2020-2025 Wrangler 4xe and 2022-2026 Grand Cherokee 4xe vehicles. It replaces 24V-720 (September 2024) and 23V-787 (November 2023), and vehicles repaired under either need the new remedy. The high-voltage battery may fail internally and cause a fire while parked or driving. Owners are told not to charge and to park outside and away from structures until dealers update the battery software and replace the battery as necessary, free of charge. FCA's filing adds a warranty extension with no time or mileage limit that replaces the battery on affected vehicles showing the related warning messages.

NHTSA recall

High

NHTSA 22V-768 (October 2022) covers certain 2022-2023 Wrangler 4xe vehicles whose battery pack was built with incorrect fasteners securing the 200-amp fuse, which can generate excessive heat. Dealers inspect and replace the fuse and replace the battery assembly if it is damaged, free of charge.
