Driving my vehicle on two occasions the brakes just automatically engaged, an error warning with an exclamation mark flashed briefly then went away. The car did not come to a complete stop but engaged the brake for at least 2 seconds. I was driving approximately 30-40 mph. I took it to the dealership were they indicated that they get about two complaints a month on this issue. They stated they believe the car falsely recognized someone in front of me and engaged the brakes. The dealership was unable to recreate the issue and said they found no signs of the warning that came on the screen in the logs. I was able to provide the exact times that the issue occurred so Im concerned there was no log of it. If I was on the express way and the brakes engaged it would have caused a serious accident. The fact that there is no way to trace the issue is concerning to me, as well as the serious safety implications that cannot apparently be reproduced or an error that was not logging but still notifying me that it occurred. This issue occurred multiple times several months apart
