Fiat Chrysler is recalling 1.1 million U.S. cars and SUVs due to drivers' difficulty using the transmissions, the automaker announced Friday. Drivers were apparently confused by the cars' electronic shift levers, The New York Times reports. That can lead to them accidentally not putting cars in park when the engine is still running, which in turn can cause vehicles rolling away and injuries. "Unless due care is taken, drivers may draw erroneous conclusions about the status of their vehicles," Fiat Chrysler said. The affected vehicles are the 2014 Jeep Grand Cherokee, 2012-2014 Dodge Charger, and Chrysler 300.
