I was driving on a clear flat surface street and all of a sudden the brake warning started to flash and then my vehicle shook a little and then automatically stopped. There were no cars in front of me. Fortunately the car behind me was able to swerve to prevent a catastrophic accident. The car behind was a large utility van with metal in the front - he would have completely smashed my car. My son was in the backseat and slightly injured. In the past, this brake warning has come on numerous times without any cars in front but has not stop automatically. This was the first time. I'm scared to drive the car now. We took the car in today for inspection. I heard this has happened for 2018 CRV's.
