Hyundai Elantra: Brake system

The malfunction indicator lamp (MIL) warns of potential engine or emissions issues in your Elantra. It illuminates for a wide range of faults, from minor sensor glitches to serious powertrain failures. A blinking MIL often means immediate attention is required to prevent damage. Drivers should use an OBD-II scanner to retrieve diagnostic codes. Ignoring the light can reduce engine efficiency and increase repair costs. Sometimes the issue is as simple as a loose fuel cap. Addressing it early protects critical systems. Some problems may not be felt immediately in driving behavior. But unseen faults can worsen over time. The MIL is a key part of modern vehicle self-diagnostics.
