General Motors is recalling 42,904 Chevrolet Malibu Eco, Buick LaCrosse and Buick Regal sedans due to a problem with the generator control module. The 2012 and 2013 models equipped with GM's eAssist hybrid system are affected.
"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," NHTSA said in its summary of the problem. "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."
No injuries or crashes have been reported as a result of the fires.
The North American carmaker has not yet provide a notification schedule, but owners can contact GM at 1-800-521-7300 or NHTSA at 1-888-327-4236. Dealers will test the GCM and replace it, as necessary, free of charge.
