NHTSA's recall notice
As NHTSA's recall record states it for campaign 16V521000.
Defect description
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.
Safety consequence
A vehicle stall increases the risk of a crash.
Manufacturer remedy
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.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
