DETROIT (AP) — U.S. auto safety regulators are investigating complaints that the engines can stall without warning in three Chrysler and Dodge brand cars.

The probe covers more than 192,000 Chrysler 300C luxury cars, Dodge Charger muscle cars and Dodge Magnum wagons from the 2006 model year. The cars have 5.7-liter or 6.1-liter V-8 engines.
