ABS (Anti-Lock Braking System)

A safety system that prevents wheels from locking up during hard braking, maintaining steering control.

What It Means

ABS uses wheel speed sensors and a hydraulic control unit to rapidly pulse brake pressure, preventing wheel lockup during emergency stops. ABS-related recalls often involve sensor failures, hydraulic pump malfunctions, or software errors that can affect braking performance. ABS has been mandatory on all new passenger vehicles in the U.S. since 2013.
