Campaign Description
In certain 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 exterior surfaces of specified underbody components. This service campaign bulletin describes the
procedure to perform this preventative service on certain Accent (RB) vehicles.

Applicable Vehicles (Certain):

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.

customer. The dealer must submit a Prior Approval request before starting repairs.

Repair Process/Information:

Recommended Service Technician Training Level: Hyundai Certified or higher
Prior to repair, it is recommended to allow the vehicle to cool at least four hours before starting the service
procedure. Parking the vehicle at the stall overnight is highly recommended to avoid a need for a cool down
period and to improve work efficiency. Then, when ready to perform repairs, apply undercoating spray and cavity
wax to areas indicated in TSB 23-01-058H (or latest version).

Recommended Alternative Transportation
A Service Rental Vehicle (SRC) should be provided to customers if their vehicle requires to be kept overnight. In
addition, a SRC may be required based on the repair procedure duration and any other additional work on the
vehicle that may need to be addressed during customer’s visit.

If a SRC is not available, other options such as a 3rd Party Rental or Rideshare may be provided.

Sample Customer Talk Tracks
“Today we are going to perform a procedure to the underbody of your vehicle to help prevent corrosion to the
chassis, brake and suspension components from road salt commonly used to de-ice the road surfaces. If the salt
is not removed by regular car washes during the winter season, it can also eat away at the paint leaving the metal
components without protection from corrosion. This service will be provided to you for no charge.”

Recommendations & Tips for Customers
•

•
•

Get regular car washes. Spray your car down at least once a week in snowy conditions and visit a car
wash that targets the undercarriage at least once a month and after winter storms. It may help to view
this expense as a highly recommended preventative vehicle maintenance, as it could save you money on
costly damages later.
If your vehicle is over 8 years old, it needs some extra TLC. Several years of exposure to winter road salts
can take its toll. According to the National Highway Traffic Safety Administration (NHTSA), vehicle models
made in 2007 and earlier are especially susceptible to brake pipe corrosion due to salt exposure. Bring
your vehicle in regularly to inspect for corrosion and take notice of how your brake pedal feels in cold
weather. Any changes could indicate a leak in the brake system.
Use a synthetic wax to provide a protective barrier from harsh salt.
Once spring arrives, thoroughly detail the exterior so that salt doesn’t sit on the surface.
Prep for winter weather early next season, making sure to pay special attention to any chips or scrapes
in the paint, as those areas will be more susceptible to rust.
