GM is aware of two injuries related to the issue, Automotive News said. The company is recalling cars from the 2011-2013 model years for a software update to limit how long the car can be left idling, the website said. GM could not be immediately reached for comment. The company also told dealers to halt deliveries of about 2,300 Chevrolet Trax and Buick Encore small crossovers from model year 2015 for a pending safety recall to fix a potential loss of electric power steering, Automotive News reported.
