Fiat Chrysler's US arm announced Thursday the recall of more than 1.7 million cars and trucks on Thursday for problems including air bag risks, bad welds and electrical wiring risks. FCA US said it was recalling 1.35 million 2012-2014 Ram pickups and other trucks in the US and other markets to inspect and fix steering wheel wiring harnesses which can wear to the point of causing a short circuit that could inadvertently deploy the driver's air bag. Chrysler said it knew of two injuries due to the problem, but no accidents.
