Fiat Chrysler said Saturday that it is recalling more than half a million more trucks in the U.S. to fix faulty impact sensors, a day after it announced an even bigger U.S. recall to update vehicles' software in order to safeguard it from hacking.
The faulty sensors could cause seat belt pre-tensioners to activate and air bags to deploy unexpectedly, increasing the risk of a crash or injury, according to a statement posted on the U.S. Department of Transportation website.

Fiat Chrysler said it is aware of two minor injuries that were potentially related to the fault, but no accidents. The company also said in an e-mailed statement that the problem was mainly affecting four-door vehicles.
The automaker said Friday that it was recalling about 1.4 million cars and trucks in the U.S. after two hackers revealed that they were able to take control of a Jeep Cherokee SUV over the Internet. In that recall, Fiat Chrysler said it would update software to insulate the vehicles from being remotely controlled.
Fiat Chrysler's announcement Saturday affects 2013 to 2015 Ram pickups and affects 667,406 vehicles in the U.S., as well as a further 176,130 vehicles overseas. Chrysler will notify owners and update a control module in the vehicles at no cost.
