UNITED STATES AND POSSESSIONS
The National Traffic and Motor Vehicle Safety Act, as amended, provides that
each vehicle that is subject to a vehicle recall campaign must be adequately
repaired within a reasonable time after the owner has tendered it for repair. A
failure to adequately repair within 60 days after a tender of a vehicle is prima
facie evidence of failure to repair within a reasonable time. If the condition is not
adequately repaired within 60 days, the owner may be entitled to replacement
with an identical or reasonable equivalent vehicle at no charge, or to a refund of
the purchase price less a reasonable allowance for depreciation.
Dealers must correct all vehicles subject to this campaign at no charge to the
owner, regardless of mileage, age of vehicle, or ownership, from this time
forward.
Dealers should proceed immediately to make necessary correction to units in
inventory. Federal law prohibits a dealer from delivering under a sale or lease, a
new motor vehicle or any new or used item of motor vehicle equipment (including
a tire) covered by the notification of a recall until the defect or noncompliance is
remedied .
. Dealers must make every effort to promptly schedule an appointment with each
owner to repair his or her vehicle as soon as possible. However, consistent with
the customer notification, dealers are expected to complete the repairs on the
mutually agreed upon service date.
Dealers involved in the recall process will be furnished a listing of owner names
and addresses to enable them to follow up with owners and have the vehicles
corrected. Use of this listing must be limited to this campaign because the list
may contain information obtained from state motor vehicle registration records,
and the use of such motor vehicle registration data for purposes other than this
campaign is a violation of law in several states.

CUSTOMER LETTER
Print ready (PDF file) copy of the Customer Letter
REVISION STATEMENT
Parts and Service procedure have been updated to begin replacing grille
surrounds on HX615 and HX620 series trucks.
DEFECT DESCRIPTION
Over time, the grille surround may come loose from the eight mounting brackets
that secure it to the hood. This may cause the grille surround to separate from
the truck. A grille surround that separates from the truck and falls to the roadway
while the vehicle is in operation can increase the risk of a vehicle crash that may
result in property damage, personal injury, or death.
MODELS INVOLVED
NOTE: For HX615 and the HX620 vehicles, a new grille surround is
available at this time.
NOTE: For HX520 vehicles, a new grille surround is NOT available at this
time. When a new grille surround is available, this document will be
updated, and customers will be notified. Until that time, if the grille
surround on an HX520 is found loose at the time of write-up, the interim
repair should be completed. There are no inspection-only claims.
This safety recall involves certain 2020 thru 2024 International® HX® Series
trucks built 03/13/2019 thru 02/28/2023.

Descriptive Information : • The suspect population is identified by the models of the vehicle, HX520 and HX620.
• The inclusive dates of manufacture were determined by when there was a design change to the grille surround.
• The vehicles in the suspect population were built with a steel grille surround; all other models use a non-metallic grille surround.
There are 5808 HX series trucks in the suspect population.
Production Dates : MAR 13, 2019 – FEB 28, 2023
VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect :
Description of the Defect : The grille surround is attached to eight (8) mounting brackets by a bonding material. Over time, corrosion can develop between the two dissimilar metal components and cause the bonding material to lose adhesion, resulting in the grille surround coming loose one bracket at a time and could cause the grille surround to separate from the truck.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : A grille surround that separates from the vehicle and falls to the roadway
while the vehicle is in operation, can increase the risk of a vehicle crash that may result in property damage, personal injury or death. To date, there have been no reported crashes for this issue. Description of the Cause : Insufficient plating in the area where the eight (8) mounting brackets are Part 573 Safety Recall Report 23V-170 Page 2 Identification of Any Warning
that can Occur : attached to the grille surround results in a small area of bare steel susceptible to corrosion over time.
Driver would hear the grille surround rattling when the vehicle is in operation and should notice that grille surround is not flush against the hood during a pre-trip walk around inspection. Involved Components : Component Name 1 : Grille Surround Component Description : Surround Assembly
