There are few things more critical than the parts that keep you in direct command of your vehicle. Among them, the 09 WRX STI Hatch Steering Wheel Horn Assembly plays a dual role: it ensures your horn system functions flawlessly for safety on the road, and it integrates seamlessly with your steering wheel controls to maintain that sporty, factory-fresh feel you expect from your Subaru. When your horn assembly starts to fail—whether it’s a weak sound, intermittent function, or complete silence—you’re not just losing a convenience feature; you’re compromising safety. That’s where Genuine Subie Parts steps in with an OEM Subaru horn assembly replacement designed specifically for the 2009 Subaru WRX STI Hatchback.
If you’re tired of dealing with unreliable aftermarket parts or worrying about fitment issues, this OEM steering wheel horn assembly for the 09 WRX STI Hatch is your peace of mind. Built to Subaru’s exact factory specifications, this component is engineered to restore full horn functionality, preserve compatibility with your airbag system, and keep your steering wheel setup intact.
At first glance, the subaru steering wheel horn assembly might seem like a minor part of your Subaru, but it’s far more than a button that makes noise. This assembly acts as the electrical bridge between your steering wheel horn switch and the horn unit itself. Without it, that all-important warning blast to alert other drivers simply won’t happen.
The 09 WRX STI Hatch Steering Wheel Horn Assembly is also tied into your steering wheel’s overall electrical system. That means it works in harmony with the airbag clock spring, cruise control switches, and other controls. When you install a genuine OEM Subaru replacement, you’re ensuring proper electrical conductivity and maintaining the safety features that make the WRX STI such a reliable performance machine.
Choosing an aftermarket horn assembly can lead to frustrating misalignments, poor electrical connections, or even issues with your SRS (Supplemental Restraint System). That’s why OEM Subaru parts are the smarter investment. This 09 WRX STI Hatch Steering Wheel Horn Assembly OEM offers:
Perfect Fitment – Designed specifically for the 2009 Subaru WRX STI Hatch steering wheel setup.

Wondering whether it’s time to replace your horn assembly? Here are common signs:
Horn doesn’t work at all – Pressing the steering wheel produces silence.
Intermittent function – Sometimes it works, sometimes it doesn’t.
Weak or muffled horn sound – Electrical connection may be compromised.
Issues with steering wheel electronics – Malfunctioning horn assembly can affect other steering controls.
If you’ve been experiencing any of these issues, replacing your horn assembly with the 09 WRX STI Hatch Steering Wheel Horn Assembly OEM is the solution.
Installing the OEM horn assembly is a straightforward process for anyone familiar with steering wheel components.

This assembly is designed exclusively for the 2009 Subaru WRX STI Hatchback, ensuring a precise fit. If you drive another year or trim, be sure to check our Steering & Electrical Parts category to find the right OEM match.
The horn assembly sits directly beneath the steering wheel cover, integrated with the horn pad. It connects to both the clock spring (SRS reel) and the horn wiring harness, completing the circuit when you press the steering wheel horn button. It’s a small part, but one that’s essential for safety, communication on the road, and maintaining that original Subaru driving feel.
