Code result

P2591

Cruise Control Front Distance Range Sensor Left

Moderate severity

What it means

General fault on the left-side front distance-range sensor used by adaptive cruise. Multi-sensor radar arrays use left/center/right sensors for wider field-of-view and lane discrimination — without left, ACC may degrade to single-target tracking.

Is it safe to drive?
