2021-2025 Hyundai Elantra Inoperable Horn TSB

Hyundai has released Technical Service Bulletin (TSB) 25-BE-005H, addressing a potential issue with the horn assembly in certain 2021-2025 Hyundai Elantra vehicles. This bulletin, identified as warranty extension Z03, covers cases where the vehicle's horn may become inoperable.

The TSB provides instructions for replacing the horn assembly with an updated design and extends the warranty coverage for this specific repair.

Symptoms

The primary symptom of this issue is an inoperable horn. Owners may find that when they attempt to use the horn, it does not sound or produces a weak/intermittent sound. This can pose a safety risk as the horn is a crucial warning device.

Fault Codes / DTCs

This Technical Service Bulletin (TSB) does not mention any specific Diagnostic Trouble Codes (DTCs) associated with an inoperable horn. The issue is typically identified by the horn's failure to function.

What the Service Bulletin Says

TSB 25-BE-005H details the procedure for replacing the horn assembly. Hyundai has extended the warranty coverage for this specific repair to 10 years or 120,000 miles, whichever comes first, from the original retail delivery date or date of first use. This extended warranty applies to both original and subsequent owners.

The bulletin instructs technicians to replace both the high-pitch and low-pitch horn assemblies. The new horn assemblies, with part numbers like 96611-AA900QQH and 96621-AA900QQH (low pitch), or 96611-AA700QQH and 96621-AA700QQH (high pitch), are designed to be installed vertically. This vertical orientation, with the bell holes facing downward, is crucial to prevent water intrusion, which is believed to be a factor in the original horn's failure.

Technicians are required to document the repair with photos of the original horn in its horizontal position before replacement. The process involves removing the front bumper assembly to access the horns.

What to Do

If you own a 2021-2025 Hyundai Elantra and are experiencing an inoperable horn, you should contact your authorized Hyundai dealership. Inform them about TSB 25-BE-005H and the warranty extension Z03 for horn replacement.

Since the warranty coverage has been extended to 10 years or 120,000 miles, your repair may be covered at no cost. The dealership will diagnose the issue and perform the necessary horn assembly replacement according to the TSB guidelines.
