NHTSA authorities disagreed with Fiat Chrysler about the seriousness of the Uconnect hack, reported Bloomberg, and pushed back on the Auburn Hills, Michigan, automaker, a move that triggered the recall of 1.4 million affected cars and trucks eight days after regulators became aware of the problem. Fiat Chrysler was already reeling after being slapped with a $105 million fine in June for mishandling nearly two-dozen recalls.
