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?
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.
