Collision mitigation braking system malfunctioned on 4/23/24 causing automatic abrupt braking when driving over metal hole cover in road. The braking was so intense the car behind our family nearly collided with our car. In the moment this happened the car was not in driver’s control as a result of malfunction. Contacted local honda dealer by phone who was familiar with the issue and advised there is no doubt the cause is the cmbs and there is no diagnostics or resolution for the problem.
