GM recalls 2012 and 2013 Buick LaCrosse and Regal; 2013 Chevrolet Malibu Eco vehicles equipped with eAssist

General Motors recalled certain model year 2012 and 2013 Buick LaCrosse and Regal, and model year 2013 Chevrolet Malibu Eco vehicles equipped with eAssist. These vehicles may have a condition in which 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.

If the vehicle is continued to be driven, the engine may stall and/or the vehicle may not start. In addition, there may be a burning or melting odor, 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 manufacturer has not yet provided a notification schedule.
