NHTSA Complaint #11713248 — 2025 HONDA PASSPORT

I am reporting a serious nighttime visibility and driver-assistance safety issue with my 2025 Honda Passport. During evening driving, approximately 60% or more of the upper portion of the windshield appears blacked out or severely dimmed, significantly impairing forward visibility. This condition worsens on downhill grades, where an even greater portion of the windshield darkens. Visibility improves when high beams are manually activated; however, driving continuously with high beams is unsafe and inappropriate. This creates an unreasonable risk of collision, particularly on unlit roads and downhill grades, as pedestrians, road curvature, and hazards are difficult or impossible to see without improper use of high beams. In addition, multiple ADAS systems operate erratically. Adaptive cruise control delays braking on downhill grades until the vehicle accelerates approximately 9–10 mph above the set speed, delays acceleration after braking and resuming, and disengages with minor steering inputs. Automatic high beams operate inconsistently. These issues persist despite recalibration. The condition has existed since early ownership and continues at approximately 20,000 miles despite multiple service visits. A Honda field technician confirmed all systems were calibrated but did not perform a nighttime drive. A dealership shop foreman conducted a nighttime drive but did not share findings, and I was told he was unavailable and had already spent “enough time” on the vehicle. My initial service record included the notation “do not diagnose.” I was initially told the dealership had never encountered this issue; later I was told they had seen it on other vehicles but did not know how to fix it. A dealership-recommended nighttime comparison drive with a 2026 Honda Passport did not exhibit these issues. I also regularly drive a 2024 Honda CR-V that shows none of these nighttime visibility or ADAS problems.
