P2591 Cruise Control Front Distance Range Sensor Left
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 with P2591?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
