Fiat Chrysler Automobiles NV recalled about 4.8 million U.S. vehicles to fix a software glitch that could keep a driver from being able to deactivate the cruise-control system. The Italian-American automaker advised customers driving select Ram pickups, Jeep SUVs and Chrysler and Dodge brand models to avoid using cruise control until the software in their vehicles is upgraded. The U.S. National Highway Traffic Safety Administration issued an advisory to “strongly encourage” that consumers follow the directive.
