New Safety Recall Advanced Communication – Z71

FCA US LLC (FCA US) has announced a safety recall on certain 2021 Model Year (JL) Jeep® Wrangler 4XE PHEV vehicles equipped with a 2.0L engine (sales code ECX).



Some of the above vehicles may have been built with an incorrect fastener to retain the 200-amp fuse. An incorrect fastener can cause high resistance in the 200-amp fuse interface, which will generate heat. Excessive heat in the fuse interface may cause the fuse to fail resulting in a loss of motive power, which can cause a vehicle crash without prior warning.



FCA US will conduct a voluntary safety recall to inspect the High Voltage Battery (HVB) fuse for the correct fasteners. If an incorrect fastener is found, FCA US will replace the fuse assembly. If charring or discoloration is present on the bus bars, FCA US will replace the HVB pack assembly. The remedy for this condition is not currently available. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in 4th Quarter of 2022.
