NHTSA recall 18V161000
Hybrid Propulsion System · Kia America, Inc.
Details
What's wrong: These vehicles are equipped with a voltage protection device (vpd), designed to protect the high voltage battery module, that may activate inadvertently.
Why it matters: 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 fix: Kia will notify owners, and dealers will remove the vpd switch and install two newly designed battery management systems (bms) that contain overvoltage protection devices (opds), free of charge. The recall is expected to begin May 2018.
