Service bulletin WTY023_DPSM

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

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. If the engine is off or if the power steering system becomes inoperative, the vehicle may be steered, but it will require increased steering effort by the driver. This warranty extension is to address specific concerns with the functionality of the MDPS unit.
