Description: In some areas, a vehicle’s underbody may exhibit corrosion due to road salt usage. As
a preventative measure, cavity wax coating is applied to the internal surfaces of underbody
components, and an undercoating spray is applied to the bottom exterior surfaces of specified
underbody components. This bulletin describes the procedure to perform this preventative service on
certain Santa Fe (NC), and Santa Fe XL (NC) vehicles.

Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota,
Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West
Virginia, Wisconsin, and the District of Columbia.
Please note all dealers must perform this service campaign if vehicle comes in with an open campaign, even if
vehicle is no longer located in the listed states above.
