ATTENTION: ALL DEALER PARTS & SERVICE MANAGERS
KiaeBay logo is extending the New Vehicle Limited Warranty coverage, to all owners, for repairs related to the horn assembly for
eligible vehicles from 5 years / 60,000 miles to 10 years / 120,000 miles, whichever comes first, from the date the vehicle was
first put into service. This warranty extension is to address a horn sound malfunction condition on the vehicles listed below:

2021-2025 MY Sorento vehicles manufactured from September 10, 2020, through June 3, 2025.

2021-2025 MY Sorento HybrideBay logo (HEV) vehicles manufactured from September 2, 2020, through January 24, 2025.

2022-2025 MY Sorento Plug-In HybrideBay logo (PHEV) vehicles manufactured from June 29, 2021, through January 20,
2025.

If, at any time during the extended warranty coverage, the subject vehicle’s horn does not emit any sound or emits an unusual
or different horn sound than normal, KiaeBay logo authorizes its dealers to diagnose the cause free of charge at no cost to the
customer.
If the above symptoms are diagnosed as being due to corrosion inside the electric horn and/or carbonization of the contact
point, KiaeBay logo authorizes its dealers to replace the horn assembly free of charge at no cost to the customer under this warranty
extension.
This is NOT a service campaign that requires a repair for all eligible vehicles. Dealers should not perform any diagnosis
or repair under this warranty extension program unless the subject vehicle’s horn does not emit any sound or emits an
unusual or different horn sound than normal. Proof of customer complaint or condition may be required.
NOTE: This extension to KiaeBay logo’s New Vehicle Limited Warranty does not alter the limitations and exclusions contained in that
New Vehicle Limited Warranty including failure of the causal part due to abuse, neglect, or external damage to the related
components.
The Technical Service Bulletin (TSB) that provides vehicle repair procedures will be posted on the KiaeBay logo Global Information
System (KGIS) at www.kiatechinfo.com, and the Warranty Bulletin describing this warranty extension will be posted on
kdealer.com on or around March 23, 2026.
NOTE: Until the TSB for this warranty extension becomes available, dealers are to perform the diagnosis and repair as
necessary on any affected vehicles under KiaeBay logo’s factory warranties. If a subject vehicle falls outside of its warranty (either
by time or mileage), dealers are to perform the diagnosis and repair under goodwill to ensure that the diagnosis and
repair of the symptoms covered under this warranty extension program are free of charge to the customer.
OWNER NOTIFICATION
KiaeBay logo will notify owners advising them of the Warranty Extension Program beginning on March 25, 2026. Note that owners
who have incurred expenses to remedy this issue prior to the date of this notice may have the opportunity to obtain
reimbursement for that expense by submitting receipts online to KiaeBay logo via http://customercare.kiausa.com or by mailing the
Request for Reimbursement Form along with their documentation to KiaeBay logo for review and consideration.
