Two months after receiving a record $105 million fine for lapses in U.S. auto safety recalls, Fiat Chrysler Automobiles NV (FCHA.MI) on Tuesday revealed problems with safety data that could lead to additional financial penalties for the Italian-U.S. automaker. Fiat Chrysler said it was investigating discrepancies in early warning reports that federal law requires automakers to provide to the National Highway Traffic Safety Administration, the federal auto safety watchdog. The reports include data that could identify safety defects and ultimately lead to product recalls.
