A steady ABS light on your Sonata VIII usually points to a wheel speed sensor or wiring issue. Here’s what to check first and whether you can keep driving safely.
Why Your Sonata VIII’s ABS Light Stays On
It’s unsettling when a warning light refuses to go out, especially on a car as refined as your Hyundai Sonata VIII. A continuously lit ABS light almost always means the anti-lock braking system has disabled itself because it detected a fault. The most common culprit by far is a wheel speed sensor — one of the four sensors that monitor how fast each wheel is turning. Dirt, metal debris, a failing sensor, or a frayed wire can interrupt that signal, and the ABS module responds by turning on the light and shutting down ABS to protect you. Other possibilities include a damaged tone ring (the toothed ring on the axle), corroded connectors, low brake fluid, or — less often — a faulty ABS module or pump.
