The Jeep Wrangler 4xe, Jeep’s first plug-in hybrid for their iconic off-road vehicle, brings a mix of rugged performance and electric efficiency, but it hasn’t been without issues—especially concerning its high-voltage battery. The Wrangler 4xe pairs a 2.0-liter turbocharged engine with electric motors, achieving around 21 miles of electric-only range, and has gained attention as a more eco-conscious option in the Jeep lineup. However, there have been several challenges with its battery that Jeep has addressed through recalls and updates.
One significant issue with the Jeep Wrangler 4xe’s battery has been overheating in the high-voltage battery pack, which could lead to power loss. Some models experienced a problem due to incorrect fasteners on the 200-amp fuse, causing overheating, which could potentially lead to complete power failure while driving. Jeep issued a recall for over 2,500 Wrangler 4xe models manufactured between January 2022 and September 2022, promising to replace the fuse assembly or, if necessary, the entire battery pack for affected vehicles. Dealers have been advised to inspect these models, and Jeep has provided instructions to replace defective components free of charge for owners.
Consumer Reports
More recently, Jeep has also been investigating a possible fire risk in certain Wrangler 4xe models from 2021-2022. Owners were advised to stop charging the vehicle and to park it away from structures due to concerns over potential fires originating from the high-voltage battery. Stellantis, Jeep's parent company, is conducting further analysis on these battery packs and has requested a voluntary recall for software updates and possible battery replacements, aiming to resolve the issue without risk to owners. This recall and investigation emphasize Jeep's commitment to safety, as they work to implement long-term solutions to prevent overheating and fire risks.
Mopar Insiders
Looking forward, Jeep has taken a proactive approach, focusing on both immediate fixes and a longer-term solution involving updated high-voltage battery software. Owners affected by these issues are expected to receive notification in early 2024, with repair work covered at no additional cost. Although these recalls have been a setback, they illustrate Jeep’s dedication to addressing problems swiftly and transparently to maintain safety and customer satisfaction.
Despite these battery issues, the Jeep Wrangler 4xe remains a popular model, accounting for a significant portion of Wrangler sales. Its ability to blend electric efficiency with Jeep’s traditional off-road performance makes it a unique choice in the growing plug-in hybrid market. With Jeep actively working on resolving battery issues, the Wrangler 4xe may still be an appealing option for those looking to balance environmental consciousness with adventure.
