A recent investigation into engine fires in some 2011 Chevrolet Cruze vehicles has been widened to include some 2012 models. The investigation was open last March after complaints of engine fires was reported in two 2011 Chevy Cruze vehicles, but additional reports of fires in some 2012 vehicles has lead the National Highway Traffic Safety Administration (NHTSA) to include the newer models. According to the investigation reports, the probe is focusing on electrical wiring and the transmission control module. If the probe leads to a recall, over 370,000 vehicles could be involved.
