My 2010 Hyundai i30 airbag warning light stays on

The first thing to check here is what’s called the clock spring. This is an electrical connector inside the steering wheel that allows the wheel to be turned to full lock and back while still allowing for electrical contact between the airbag and the rest of the car.

If this spring fails, the connection between the airbag and the systems that would trigger it in a crash are lost. Which means that in a big enough collision, the airbag would not fire and protect the driver.

Clock spring replacement is relatively simple but it’s still a job best left to the pros, as any time you’re messing with an airbag, you’re playing with a fairly violent explosive component. Get it wrong and accidentally fire the airbag, and you could be seriously injured.
