Issued by Hyundai Motor America · Reported Mar 12, 2018 · 2,840 vehicles affected

What's 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.

Consequence

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.

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.
