P0574
Cruise Control System - Vehicle Speed Too High
Moderate severity
What it means
The cruise control sees actual vehicle speed exceed the set-speed by more than the diagnostic margin (typically going downhill or with throttle override). Persistent oversize means the system cannot bring speed down - either an actuator fault, brake-blending failure, or driver kick-down stuck.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
