NHTSA Complaint #11588505 — 2021 NISSAN LEAF

Component: High Beam Assist Safety issue: The High Beam Assist system that is enabled by default with the neutral "Auto" switch on the control stalk has a faulty "light detection" system that cannot be overridden by manual driver input. The light detection system is designed to disengage high-beams when another car becomes visible, then re-engage the high-beams when the car passes. However, this system is overly sensitive and will very often disengage high beams based on street lights, reflective mail boxes, pavement reflectors, moonlight, and more. There is no available control to reliably override this disengagement. The system also prevent engagement, not just falsly triggering disengagement. For example, if you see an obstacle while using low-beams, and attempt to quick engage high-beams by pushing the control stalk, the system will not engage high-beams because the sensor falsely detected a light source. You can flick the control stalk back and forth repeatedly, and the high-beams will not engage in Auto.
