2024-2025 Hyundai Elantra Steering Wheel Vibration TSB

Important Warnings for Owners

Hyundai emphasizes that this field action requires a customer concern and a confirmed case of the related symptom before any repair work can begin. If these justification requirements are not met, any submitted claims may be subject to debit. The repair is covered under the 5-year / 60,000-mile New Vehicle Limited Warranty, provided the vehicle is within the warranty coverage period based on mileage and date of first use.

Symptoms

Owners of certain 2024-2025 Hyundai Elantra (CN7) vehicles may experience a noticeable "vibration in the steering wheel when the cooling fan is operated at high speed." This Hyundai Elantra steering wheel vibration occurs specifically when the engine cooling fan is running at its higher speed setting.

Diagnosis / Trigger Conditions

To diagnose the Hyundai Elantra steering wheel vibration, technicians will perform a specific inspection procedure. This involves connecting a Global Diagnostic System (GDS) to the vehicle and turning the ignition ON. The technician will then navigate to the "Actuation Test" menu, select "ENGINE," and choose "Fan Motor Control-High Speed" to activate the cooling fan. While the fan is operating at high speed, the technician will place a hand on the steering wheel to check for excessive vibration. If no excessive vibration is felt, the Technical Service Bulletin (TSB) does not apply. If significant vibration is present, the repair procedure will be initiated.

Repair Procedure Summary

The repair procedure outlined in TSB 26-EM-007H focuses on replacing the cooling fan blade. The steps involve:

1. Preparation: Disconnecting the negative battery terminal and the overflow hose. The filler neck assembly is removed, ensuring the upper engine coolant radiator hoses remain intact.
2. Access: The air cleaner assembly and intake shield are removed to gain access to the cooling fan. The cooling fan controller connector is then disconnected.
3. Cooling Fan Removal: The coolant filler neck is secured away from the cooling fan, typically with a bungee cord. The entire cooling fan assembly is carefully removed from the radiator.
4. Blade Replacement: Coolant is drained from the overflow tank. The original cooling fan blade is then detached from the assembly and replaced with the new, updated part. Three fasteners are tightened to specific torque specifications.
5. Documentation: Technicians are required to take a photo of the mold date stamp on the original cooling fan blade using the STUI camera function and upload it. If STUI is unavailable, the last 6 digits of the VIN and the repair date must be written on paper and included in the photo.
6. Reassembly and Verification: All components are reinstalled in reverse order of removal, ensuring all fasteners are torqued to the recommended specifications. The coolant overflow tank is replenished with approximately 10 oz. of Pink Coolant (part number 00232-19098) and 10 oz. of diluted/filtered water. Finally, the vehicle is started to verify that the Hyundai Elantra steering wheel vibration is no longer present.
