Hyundai Sonata Plug-IN Hybrid Recall 18V166: Sudden Power Loss in EV Mode Can Raise Crash Risk

NHTSA campaign 18V166, reported March 12, 2018, 2,840 vehicles potentially affected.

What this recall means for you

Certain 2016-2018 Hyundai Sonata Plug-In Hybrid vehicles are equipped with a Voltage Protection Device (VPD), which is designed to protect the high voltage battery module. The VPD may activate inadvertently, and if this happens while the vehicle is being driven in Electric Vehicle (EV) mode, the vehicle may lose power. A sudden loss of power increases the risk of a crash.

Hyundai will notify affected owners. Dealers will remove the VPD switch and install a new Battery Management System (BMS) that contains an Overvoltage Protection Device (OPD). The repair is free at an authorized Hyundai dealer. The recall is expected to begin in May 2018.

Owners can contact Hyundai customer service at 1-855-371-9460 and reference Hyundai recall number 175. You can also check your vehicle identification number (VIN) for open recalls to confirm whether your vehicle is affected.
