General Motors has decided that a defect relating to motor vehicle safety exists in certain 2016 Chevrolet Malibu Hybrid vehicles equipped with a manual service disconnect (MSD).

The MSD is a shut-off switch designed to disconnect power before servicing. In some vehicles, the MSD was not installed properly and could become loose and disconnect while driving. The engine will stall and may affect the driver’s ability to control the vehicle.

Dealers will inspect the MSD and seat the connector properly, if necessary. A software update will also be installed to monitor and detect if the high voltage interlock loop (HIVL) is connected correctly. Owners wanting more information about the problem are asked to contact Chevrolet customer service at 1-800-222-1020. GM’s number for this recall is 51230 and the NHTSA campaign number is 16V-521.
