The problem
General Motors (GM) is recalling 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.
The risk
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.
The fix
GM will notify owners and dealers will test the GCM and replace it, as necessary, free of charge. The recall began on June 11, 2013. Owners may contact GM at 1-800-521-7300. GM's recall campaign number is 13136.
