US investigating reports that some Jeep SUVs and pickups can catch fire after engines are turned off

U.S. auto safety regulators are investigating reports that the engines can catch fire on some Jeep SUVs and pickup trucks even with the ignition turned off.

The probe covers more than 781,000 Jeep Wrangler and Gladiator vehicles from the 2021 through 2023 model years.

The National Highway Traffic Safety Administration says in documents posted Monday on its website that it has nine complaints of engine fires from owners including one that caused an injury. A majority of the reports say fires began in the passenger side of the engine compartment.

The agency says a fire with the ignition off “can result in an increased risk of occupant injury, injury to persons outside the vehicle, and property damage, with little or no warning.”
