2022 Hyundai Tucson Inoperable Horn Warranty Extension

Hyundai has announced a warranty extension for certain 2022 Hyundai Tucson (NX4A) vehicles due to a potential issue with the horn assembly. This extension, detailed in Technical Service Bulletin (TSB) 26-BE-004H, addresses situations where the horn may become inoperable.

The problem is attributed to foreign substances causing internal parts of the horn to oxidize. This can lead to the horn failing to function when activated. The warranty coverage for this specific issue has been extended significantly to ensure owners are not left without a working horn.

Symptoms of an Inoperable Horn

The primary symptom of this issue is an inoperable horn. Owners may find that when they attempt to use the horn, it either does not sound at all or produces a weak or inconsistent sound. This directly impacts vehicle safety, as the horn is a crucial warning device.

Diagnosis and Trigger Conditions

This condition occurs when foreign substances infiltrate the horn assembly, leading to oxidation of its internal components. To confirm the Hyundai Tucson inoperable horn condition, a dealership technician will verify that the horn is indeed not functioning correctly. This verification is a mandatory step before any repairs under this warranty extension can proceed.

Repair Procedure Summary

If your 2022 Hyundai Tucson is found to have an inoperable horn due to this condition, the repair involves replacing both the low pitch and high pitch horn assemblies. Technicians will follow the detailed service procedure outlined in TSB 26-BE-004H (or its latest version) to ensure the correct installation of the new components.

Required Parts

The following horn assembly parts are required for this repair:

• Part Number 96641-CW500QQH (Horn Assembly - Low)
• Part Number 96651-CW500QQH (Horn Assembly - High)

These parts will require a VIN before ordering to ensure compatibility and correct part allocation.

Warranty Information and Coverage

Hyundai is extending the warranty coverage for the horn replacement to 10 years or 120,000 miles, whichever occurs first. This period is calculated from the date of original retail delivery or the date of first use. This extended coverage applies to both original and subsequent owners of the affected vehicles.

It is important to note that this is a warranty extension, not a recall. The replacement of the low and high pitch horns will be offered at no cost to the customer if the condition is covered by this warranty extension.

Important Warnings for Owners

• Verification Required: The customer's concern of an inoperable horn must be verified by the dealer before any repairs can be performed under this warranty extension.
• Claim Submission: If the affected parts fall within the extended period of 10 years/120,000 miles, the dealer must submit the claim as a campaign claim type, not a standard warranty claim.

Owner Action

If you own a 2022 Hyundai Tucson (NX4A) and are experiencing an inoperable horn, you should contact your authorized Hyundai dealer to schedule an inspection. The dealer will verify the condition and perform the necessary repairs under the terms of this warranty extension, TSB 26-BE-004H.

Hyundai expects to notify owners of the subject vehicles via First Class Mail in March 2026. However, you do not need to wait for this notification to have your vehicle inspected if you are experiencing the issue.

Alternative Transportation

If your vehicle needs to be kept overnight for the repair, a Service Rental Vehicle (SRC) should be provided. Alternative transportation, such as a 3rd Party Rental or Rideshare, may also be offered based on the repair duration or if additional work is needed during your visit.
