The problem
General Motors LLC (GM) is recalling certain model year 2016 Malibu Hybrid vehicles manufactured October 27, 2015, to June 3, 2016. The affected vehicles have a shut-off switch for the high voltage battery for use when servicing the vehicle. This manual service disconnect switch (MSD) may not be properly installed and thus may not lock into position, unexpectedly disconnecting the high-voltage power while driving, effectively stalling the vehicle.
The risk
A vehicle stall increases the risk of a crash.
The fix
GM will notify owners, and dealers will inspect the MSD and correct the installation, as necessary, free of charge. The recall began on August 10, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 51230.
