Almost 14,000 examples of the 2022-2023 Jeep Wrangler 4xe Plug-In Hybrid are being recalled in the United States because of a battery pack issue.
The car manufacturer has revealed that select Wrangler models may have been built with incorrect fasteners securing the 200 amp fuse in the high voltage battery pack assembly. Jeep says that an incorrect fastener can cause high resistance in the 200 amp fuse interface and generate unwanted heat.
Excessive heat in the fuse interface may cause the fuse to fail, triggering a loss of power, increasing the risk of a crash and injury. Owners of impacted vehicles may be alerted to the issue with a Malfunction Indicator Lamp, a change in drivability, and/or noise at the high-voltage battery pack assembly.

A total of 13,722 Wrangler models are involved in the recall and were manufactured between January 13, 2022 and May 18, 2022. The incorrect fasteners were introduced into vehicle production on January 13 and no longer used after May 18.
Jeep first opened an investigation into a potential issue on April 25, 2022 after receiving a report of a damaged fuse in the high-voltage battery pack assembly on a 2022 Wrangler PHEV. Over the following four days, Jeep received two additional reports of a damaged fuse and on May 2, 2022, it was determined that an incorrect fastener was to blame.
Owners and dealers will be notified on or around December 2, 2022 of the issue. Owners will be instructed to take their vehicle to a dealer where the HV battery fuse will be inspected for the correct fasteners. If an incorrect fastener is found, the fuse assembly will be replaced and if charring or discoloration is present on the bus bars, the high-voltage battery pack assembly will be replaced.
