2023-2026 VinFast VF 8 Clock Spring: Steering Controls, Airbag Lights, and Known Faults
Your guide to diagnosing and replacing the essential part connecting your VF 8's steering wheel electronics, including the airbag and control buttons.
- Before diagnosing a bad clock spring, check for a known software bug by pulling and re-inserting the F30 fuse to see if steering wheel button function returns.
- A lit airbag/SRS warning light is the most critical symptom and means the driver's airbag is disabled and will not deploy in a crash.
- There are no recalls for the clock spring itself, but several recalls exist for the VF 8's airbag and steering assist systems that you should be aware of.
- When buying a used part, verifying the OEM part number (181304000E) and ensuring the anti-rotation locking tab is intact are essential for safety and compatibility.
Diagnosing VinFast VF 8 Steering Wheel Issues
Important: Before assuming the clock spring has failed, be aware of a known software issue in some VinFast VF 8 models. Owners have reported that all steering wheel buttons can become unresponsive, which mimics a clock spring failure. This is often caused by a bug in the Steering Control Module (SCM) firmware that prevents it from "waking up" after the vehicle enters a deep sleep mode. A temporary fix for this is to reset the SCM by pulling and re-inserting its fuse (F30, 10A), located in the fuse box on the left side of the steering column. If this fuse reset restores button functionality, the clock spring is likely not the problem.
Symptoms of a Failed Clock Spring
If the fuse reset does not solve your issue, you may have a physical clock spring failure. The symptoms are caused by the internal ribbon cable fraying or breaking from the stress of repeated steering wheel rotation.
- Airbag Warning Light: The most critical symptom is an illuminated airbag or SRS (Supplemental Restraint System) warning light on your dashboard. The onboard computer detects a lost connection to the driver's airbag and triggers the light, indicating the airbag will not deploy in a crash.
- Inoperative Steering Wheel Buttons: Buttons for the radio, cruise control, or phone may stop working entirely or only function when the steering wheel is in a specific position.
- Horn Failure: The horn may not work at all, or it might work intermittently as you turn the wheel.
- Grinding or Clicking Noises: A scraping, grinding, or clicking sound coming from the steering column when you turn the wheel can indicate the broken internal ribbon is rubbing against its housing.
- Traction or Stability Control Light: On some vehicles, the clock spring assembly also houses the steering angle sensor. If this sensor's signal is lost, it can trigger warning lights for the traction control (TCS) or stability control (ESP) systems.
Known Issues, TSBs, and Recalls for 2023-2026 VinFast VF 8
As of mid-2024, there are no specific recalls for the clock spring on the 2023-2026 VinFast VF 8. However, several recalls exist for related steering and airbag systems that owners should be aware of.
| Recall / Issue | NHTSA Campaign Number | Description |
|---|---|---|
| ADAS Steering Behavior | 25V559000 | The Advanced Driver Assistance System (ADAS) may cause unexpected steering movements in wide turns that are difficult for the driver to override. The fix is a software update. |
| Center Airbag Deployment | 24V933000 | The driver's seat center airbag may deploy improperly during a side impact and strike the driver's arm. Dealers will replace the center airbag with a redesigned unit. |
| Inactive Airbag Ignitors | 24V369000 | Some vehicles may have been built with inactive airbag ignitors, which would prevent the airbags from deploying in a crash. Dealers will inspect and replace affected airbags. |
| Blank Instrument Display | 23V355000 | A software error can cause the main display screen to go blank, failing to show critical safety information. This is resolved with a software update. |
You can check for open recalls on your specific vehicle by entering your VIN on the NHTSA website.
Buying a Used Clock Spring for Your VF 8
Since a failed clock spring disables the airbag, choosing a quality replacement is critical for safety. A reliable, used OEM part is often a better choice than a new, unproven aftermarket part.
- Verify the Part Number: The most important step is to match the OEM part number. The known part number for the 2023-2026 VinFast VF 8 is 181304000E. Do not install a part with a different number, even if it looks identical, as internal wiring can vary.
- Physical Inspection: Before purchasing, carefully inspect the used clock spring. Look for any cracks or damage to the black plastic housing. Ensure all electrical connectors are intact, with no bent or broken pins.
- Check the Locking Tab: A new or properly handled used clock spring will have a locking tab in place to prevent it from spinning. If this tab is missing and the unit has been spun freely, the internal ribbon cable is likely damaged. Do not buy it.
- Examine the Pigtail Wires: Check the wires leading to the connectors for any cuts, fraying, or signs of improper removal from the donor vehicle.
- Source and Mileage: Purchase from a reputable recycler that can provide information about the donor vehicle. While mileage is a factor, a part from a 50,000-mile vehicle that is in excellent physical condition is perfectly acceptable.
Replacement Overview
Replacing a clock spring is a moderately difficult job that requires careful handling of the airbag system. If you are not comfortable with this procedure, have it performed by a professional technician.
Warning: The airbag (SRS) is an explosive device. Improper handling can cause serious injury. Always disconnect the battery and wait at least 15 minutes for the system's backup power to discharge before beginning work.
- Disconnect the Battery: Disconnect the negative terminal of the 12V battery and wait 15 minutes.
- Remove the Airbag: There are typically two bolts or clips on the back or sides of the steering wheel that release the airbag module. Carefully lift it out and disconnect its electrical connector. Place the airbag aside with the emblem facing up.
- Remove the Steering Wheel: With the front wheels pointing straight ahead, remove the large center bolt holding the steering wheel. Mark the wheel's position relative to the steering shaft before removing it.
- Remove Steering Column Covers: Unclip or unscrew the plastic shrouds around the steering column to access the clock spring.
- Replace the Clock Spring: Disconnect the electrical connectors from the old clock spring and unclip it from the column. Clip the new one in place and reconnect the wiring. Do not remove the new clock spring's locking tab yet.
- Reinstall and Center: Reinstall the steering column covers and the steering wheel, ensuring it is aligned with your mark. Once the wheel is on, you can remove the clock spring's locking tab. Torque the center bolt to the manufacturer's specification.
- Final Assembly: Reconnect the airbag module and secure it in place. Reconnect the battery.
- Test and Calibrate: Turn the vehicle on and check that the airbag light goes out. Test all steering wheel buttons and the horn. If your vehicle gives a stability control error, the steering angle sensor may need to be calibrated with a diagnostic scan tool.

Frequently Asked Questions
My steering wheel buttons don't work. Is it the clock spring?
Not necessarily on a VF 8. First, try resetting the Steering Control Module (SCM) by pulling the F30 (10A) fuse for a minute and re-inserting it. If this fixes the problem, it's a known software bug, not a bad clock spring.
Is it safe to drive with a bad clock spring?
No. A faulty clock spring means the driver's airbag is disabled and will not deploy in an accident. It is a critical safety failure that should be repaired immediately.
Why is my airbag light on after replacing the clock spring?
This can happen for a few reasons: the replacement part is also faulty, a connector was not plugged in securely, or the system stored a hard fault code that needs to be cleared with a professional scan tool. Double-check all connections first.
Does a new clock spring need to be programmed?
The clock spring itself does not typically require programming. However, if the integrated steering angle sensor loses its position, it may need to be calibrated using a scan tool to ensure the stability control system functions correctly.
