Automotive conglomerate Stellantis has issued a fire warning for 154,032 plug-in hybrid utilities sold in the U.S., warning that batteries could catch fire.

The recall affects 2020-24 Jeep Wrangler 4xe and 2022-24 Jeep Grand Cherokee 4xe models, with an estimated 5% of those vehicles potentially containing the defect. While a remedy is in the works, Stellantis has advised customers to refrain from charging their vehicles, instead using the internal-combustion part of their PHEV powertrain only; and for even greater caution, customers are advised to park away from structures and vehicles. It was noted that the risk of a fire, naturally, is reduced when the battery is depleted.

This recall was spurred by an internal investigation conducted after a routine review of customer data in which 13 fires were identified. According to a report issued by the National Highway Traffic Safety Administration, two alleged injuries have been reported to date. To fix the issue, the report claims, Chrysler dealers will update the battery control module software and inspect the high-voltage battery, replacing the pack if needed.

The same NHTSA briefing identifies the split as 118,230 Wrangler PHEVs and 35,802 Grand Cherokee PHEVs. Those impacted can expect to be notified starting October 17, though information on the recalls (codes 24V-720 and 24E-080) is available online now.
