## Narrative
On September 10, 2025, while my son was driving, the lane assist system activated twice during a single drive without a cause. The first activation was manually corrected, but the second caused the vehicle to veer into a roadside barrier. There were no environmental or road condition that would justify the intervention. The vehicle was declared a total loss by our insurance provider. (Please see attached Vehicle Safety Complaint Report pdf for more detail)  I am concerned this may reflect a defect in the lane assist system and could pose a risk to other drivers. I am requesting NHTSA investigate whether similar incidents have been reported.
