NHTSA campaign 18V166000 · Part 573 safety recall report

Hyundai Motor America: Hybrid Propulsion System

Hyundai Motor America reported this defect to federal regulators on Mar 12, 2018 and put the number of vehicles at risk at 2,840. The repair is free for as long as the recall stands.

The defect

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.

The risk

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.

What this page is, and what to do next

A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.

This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 18V166000.
