U.S. safety regulators are investigating possible electrical problems in older Dodge Journeys after a woman was trapped and died when her SUV caught fire in December.

The National Highway Traffic Safety Administration says it’s investigating whether inoperative door locks and windows can prevent people from getting out of the SUVs during an emergency.

Documents posted on the agency’s website say the probe covers more than 82,000 Journeys from the 2009 model year. The investigation was opened after the woman’s death on Dec. 9.

A complaint filed with the agency says the woman pulled to the side of a road when warning lights started flashing, windshield wipers came on, the horn started honking, windows wouldn’t go down and the doors wouldn’t unlock. The complaint alleged that the fire apparently started in the engine and spread.

Stellantis, which makes Dodge vehicles, offered sympathy to the woman’s family and said it is cooperating with NHTSA.
