"The issue is the potential overheating of the circuit boards in the generator control module, but it does not involve the eAssist battery," GM said in a statement.
GM said an overheating circuit board could lead to a loss of battery charge and cause the engine to stall.
"In addition, there may be a burning or melting odor, smoke, and, in rare instances, a fire in the trunk," GM spokesman Alan Adler said in a statement.
Most of the incidents occurred within the first 1,000 miles of operation, GM said and only two led to trunk fires. One was during an October screening in a dealership and the other occurred in March.
No injuries or crashes were reported as a result of the defect, GM said.
