Similar to the open investigation on these CRVs, we have had at least 3 occurrences of the vehicle activating automatic emergency breaking with nothing obstructing the vehicles path. There were, however, metal plates in the roadway to cover utility trenches. These are designed for vehicles to drive over them all day, every day, so the vehicle should not emergency stop. Although there were luckily no rear end collisions as a result of this, it was certainly possible given how abrupt the stop was.
