GM is recalling 38,197 2012 and 2013 model cars with eAssist hybrid powertrains, the Wall Street Journal reports.
The Chevrolet Malibu Eco, Buick LaCrosse, and Regal sedans all have improperly functioning generator control modules.
GM’s eAssist system uses a battery and an electric motor to supplement a traditional gasoline engine and save fuel while giving the car peppier acceleration.
The company said a malfunctioning generator control module can result in gradual loss of battery charge and activation of a malfunction warning light. If the driver ignores the warning the engine may eventually stall. The condition could also result in a burning or melting smell, and in rare cases, fires in the car’s trunk. […]
GM said it is aware of generator control board incidents, including two trunk fires. Most of these episodes took place during the first 1,000 miles of use. Cars built after December 2012 are not included in the recall. GM said it knows of no injuries related to the problem.
