A potentially failing Anti-lock Braking System (ABS) is often indicated by the intermittent illumination of the ABS warning light on the dashboard. This warning light serves as a key alert to the driver that there may be an issue within the ABS itself. The ABS is designed to prevent wheel lockup during braking, and any malfunction could compromise its function, resulting in a loss of that safety feature. When the light flickers on and off, it signifies that the system is experiencing faults that need immediate attention, suggesting the necessity for diagnostic checks and potential repairs.

Other choices relate to different potential vehicle issues. For instance, a soft brake pedal could indicate problems with the hydraulic system or brake fluid levels, but it does not specifically point to the ABS. A gradual increase in stopping distance can suggest various braking problems, including worn brake pads or components, while frequent flat tires are typically unrelated to the braking system and may indicate tire wear or other unrelated issues. Therefore, the intermittent activation of the ABS warning light is the most direct and specific indication of a possible problem within the ABS itself.
