## NHTSA's summary

WARRANTY EXTENSION: DEALER PARTS AND SERVICE MANAGER MEMO \- This document is the announcement to the dealer Parts and Service Managers of the warranty extension program for WTY023. Kia America, Inc., is extending the New Vehicle Limited Warranty coverage for the Motor Driven Power Steering \(MDPS\) unit, also known as Electronic Power Steering \(EPS\) unit, from 5 years/60,000 miles to 15 years/150,000 miles, whichever comes first, starting from the date the vehicle was first put into service. The power steering uses a motor to assist in steering the vehicle.

This warranty extension is to address specific concerns with the functionality of the MDPS unit.
