To Whom It May Concern, I am writing to formally report a serious safety issue involving the automatic emergency braking (AEB) system on my Honda Accord 2020. The system has been engaging randomly and without cause, abruptly applying the brakes when there is no obstacle or hazard present. On multiple occasions, this malfunction has occurred while driving at normal speeds, including on highways and in moderate traffic. These sudden, unprovoked braking events have created extremely dangerous situations, nearly causing rear-end collisions and putting both myself and other drivers at risk.
