## What is wrong

Hyundai Motor America \(Hyundai\) is recalling certain 2016\-2018 Hyundai Sonata Plug\-In Hybrid vehicles.  These vehicles are equipped with a Voltage Protection Device \(VPD\), designed to protect the high voltage battery module, that may activate inadvertently.


## What can happen

If the VPD activates while the vehicle is being operated in Electric Vehicle \(EV\) mode, there may be a loss of power, increasing the risk of a crash.


## The remedy

Hyundai will notify owners, and dealers will remove the VPD switch and install a new Battery Management System \(BMS\) that contains an Overvoltage Protection Device \(OPD\).  The recall is expected to begin May 2018.  Owners may contact Hyundai customer service at 1\-855\-371\-9460.  Hyundai's number for this recall is 175.


## 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.
