Owners will be notified May 7, 2026, as Stellantis inspects and replaces affected engines nationwide
Stellantis North America is recalling a batch of 2.0-liter turbocharged engines across the U.S. market. These engines, supplied through the Mopar division as replacement or service parts for the Jeep Grand Cherokee 4xe and Jeep Wrangler 4xe, could fail without warning due to debris left over from the sand casting process.
The Grand Cherokee 4xe engine carries part number 68412483AF, while the Wrangler 4xe unit is labeled 68364632CB. Both are produced by Nemak at its plant in Garcia, Nuevo León, Mexico. Although founded in 1979, the company’s roots trace back to 1879, and it has worked closely with Stellantis and its predecessor Fiat Chrysler Automobiles on materials development.
Still, Nemak fell short last year. In November 2025, Stellantis North America issued a major recall impacting 112,859 plug-in hybrid Wrangler and Grand Cherokee models in the United States. The current recall focuses specifically on 2.0-liter turbo engines sold as replacement parts through authorized Mopar retailers.
The automaker, based in Auburn Hills, began investigating in May 2025 after reports of fires and loss of propulsion from 4xe owners. The probe found that some engines weren’t properly cleaned after casting, leaving behind contamination.
At the time of the November recall, Stellantis had logged at least 144 warranty claims and 50 service records. There were also 50 field reports involving loss of propulsion, 36 fires, and 36 customer assistance cases. In total, three injuries have been reported, adding to the seriousness of the issue.
Dealers have been told to inspect all engines that haven’t yet been installed. If needed, those units will be bought back. For vehicles already equipped with the affected engines, the fix includes a replacement engine assembly and updated engine control software. Customers won’t pay for any of these repairs.
Owners can expect notifications around May 7, 2026. Around the same time, both plug-in hybrid models were quietly discontinued on January 8, 2026. Earlier that week, Jeep’s online configurator removed the 4xe options without explantion.
Stellantis says the move reflects changing customer demand, with the company now shifting focus toward traditional hybrids and extended-range electric vehicles. Models like the Ram 1500 REV and Jeep Grand Wagoneer 4xe use a 3.6-liter Pentastar V6 engine to power a generator that supplies electricity to the battery and drive units.
Looking ahead, the next-generation Wrangler, internally known as J70, is expected to offer an extended-range electric option as well. For now, the current JL lineup is available with engines including the 2.0-liter Hurricane, 3.6-liter Pentastar, and 6.4-liter HEMI. The Grand Cherokee, meanwhile, continues with the 2.0-liter Hurricane and 3.6-liter Pentastar—though supply chain issues like this one reamin a concern for the brand.
