Stellantis (FCA US, LLC) has announced a recall involving its popular Jeep® Wrangler Unlimited 4xe (JL) plug-in hybrid electric vehicles (PHEVs) for an engine shutdown condition. Approximately, 62,909 units from the 2021 to 2023 model years are affected.
Some of the above vehicles may experience an engine shutdown condition caused by diagnostic reactions to faults caused by loss of communication. An engine shutdown condition may result in an unexpected loss of power while driving, which can cause a vehicle crash without prior warning.
According to the recall, the suspect period began on 9/2/2020 (when 2021 4xe production began), and ended on 8/17/2022 (when 2023 production began with updated vehicle control software). The suspect period was determined using supplier and vehicle production records.
FCA US says the remedy is updated calibration software in the Transmission Control Module, Hybrid Control Processor, and Auxiliary Hybrid Control Processor.
FCA US will conduct a voluntary safety recall on all affected vehicles to update vehicle control software. 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. The recall is estimated to launch in Q1 2023.
