The electronic controller for the lithium ion battery can short circuit and burn on E-assist GM cars.
GM is recalling 43,000 model-year 2012 and 2013 Buick LaCrosse and Regal, and 2013 Chevrolet Malibu Eco vehicles equipped with the so-called E-assist mild hybrid system because of fires.
GM had previously performed a service action on the vehicles, contending there was no chance of fires. At least two fires subsequently occurred, and NHTSA inquiries about a number of complaints prompted GM to reopen the defect investigation, leading to the recalls.
These E-assist cars have a Generator Control Module for the 0.5 kWh battery that can short circuit and burn. The safety defect causes a gradual loss of battery charge and the illumination of the malfunction indicator light. If the hybrid continues to be driven, the engine may stall or it 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, as required by U.S. safety regulations. GM does not have a notification schedule yet. Owners may contact GM at 1-800-521-7300. GM’s recall campaign number is 13136. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 or go to www.safercar.gov about NHTSA recall 13V-173.
