US: GM recalls 42,904 Buick and Chevrolet models over defective generator control
General Motors (GM) is recalling 42,904 units of model year 2012 and 2013 Buick LaCrosse and Regal, and model year 2013 Chevrolet Malibu Eco vehicles equipped with eAssist [mild hybrid] because the generator control module (GCM) may not function properly.
This could cause a gradual loss of battery charge and the illumination of the malfunction indicator light, the automaker said.
If the vehicle is driven, the engine may stall and/or may not start. In addition, there may be a burning or melting odour, smoke, and possibly a fire in the trunk.
GM will notify owners and dealers will test the GCM and replace it, as necessary, free of charge. The recall schedule was not yet available.
