THIS TSB SUPERSEDES 22-01-089H TO ADD ELANTRA COUPE (JK) TO THE APPLICABLE
MODELS LIST.
 IMPORTANT
Dealers must perform this service campaign whenever an affected vehicle is in the shop for any
maintenance or repair.
Access the "Vehicle Information" screen via WEBDCS to identify open campaigns.
Description: In certain areas, a vehicle’s underbody may exhibit corrosion due to road-salt usage. As
a preventative measure, a 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 bulletin describes the procedure to perform this preventative service on certain 2011
– 2016MY Elantra (MD/UD) and certain 2013 – 2014MY Elantra Coupe (JK) vehicles.
Applicable Vehicles (Certain):
• 2011-16MY Elantra (MD/UD) vehicles currently or ever registered in a Salt Belt State produced
from 10/29/2010 – 12/22/2015.
• 2013-14MY Elantra Coupe (JK) vehicles currently or ever registered in a Salt Belt State
produced from 03/16/2012 – 04/24/2014.
Salt Belt Areas include:
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.

 IMPORTANT
There are circumstances under which vehicles that are not currently registered or have never been
registered in a “salt belt” state may be eligible for this service campaign. These circumstances
include:
• Vehicles that were relocated into a “salt belt” area and/or
• Vehicles registered in a “non-salt belt” state and driven in a “salt belt” area
If it is determined that an owner of a vehicle within the affected VIN production date range
relocates or has operated their vehicle in a “salt belt” area, the dealer should perform this
procedure at no cost to the customer. The dealer must submit a Prior Approval request before
starting repairs.

Wrap the brakes with plastic bags to protect
them from overspray. Use tape to secure the
plastic in place. Leave the banjo fitting area
exposed as shown.
! CAUTION
•
•
The brakes must be sufficiently cooled
before it is wrapped.
May cause burns and melt the plastic.

Wrap large plastic bags around the tires and
wheels to protect them from overspray. Use
tape to secure the plastic in place.
3.
Wrap the exhaust areas adjacent to the front
sub-frame and the rear Coupled Torsion Beam
Axle (CTBA) with plastic bags to protect them
from overspray. Use tape to secure the plastic in
place.
! CAUTION
•
•
The exhaust must be sufficiently cooled

•

•
This procedure must be performed in a well-ventilated area.
Must wear safety goggles, face protection, and gloves. Rinse eyes with water or skin
with soap and water. Do not inhale spray. Seek medical attention if needed.
Flammable & pressurized. Do not spray near flames, sparks, or heated areas. Do not
pierce can.
Apply the cavity wax at each of the locations noted in the following steps.
Generally for coating interior surfaces, insert the “inside” nozzle as deeply as possible at each point of
entry. Spray the cavity wax while simultaneously rotating the nozzle and slowly pulling the nozzle out
at a rate of about one second per inch. Continue this rotating/pulling motion until the pink tubing is
seen coming out of the hole. The pink tubing indicates about 50 mm of tubing left until in the nozzle.
Stop spraying when the pink tubing is seen.
Generally for coating exterior surfaces, use the “outside” nozzle and the wax gun. Use this nozzle if
the inside nozzle is too large to access the internal cavity of the components.
1.
Use the marked areas as a guideline to insert
the cavity wax nozzle for each of the
components. Additional access into the internal
cavity of the components might be possible.
