The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller.

This time around, NHTSA is investigating whether GM did enough in a recent recall of eAssist-equipped models, namely the 2013 Chevrolet Malibu Eco and the 2012-2013 Buick Regal and LaCrosse.
