The hazard
On certain plug-in hybrid vehicles, the battery Voltage Protection Device (VPD) switch could inadvertently activate. If the VPD switch is activated, electricity to the vehicle's electric motor may be disconnected. If this occurs while the vehicle is driven under Electric Vehicle (EV) mode, the vehicle may experience a loss of motive power, which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will remove the current VPD switch and install a newly designed battery management system module containing an overvoltage protection device. The corresponding wiring harness will also be installed. Note: This condition would result in the of the “Check Hybrid System" warning light illuminating.
