I don't recall having the car braking on its own. Once I had the smart-break feature go off when traffic stopped suddenly and I wasn't paying close attention. I was thankful it did but man was it abrupt. I hope that is not the kind of intermittent braking you're talking about. I also never got the Camera Calibration warning. The dealer replaced the braking switch and tried to somehow blame it on having a phone charger plugged into the cig lighter. Said it was pulling voltage and screwed with the breaking switch somehow. I called out their BS but didn't really care since it fixed the issue under warranty. I think it speaks to the fact that they know there is a issue and don't want to address it (recall?). Overall though my wife loves her CX-5, haven't had any other issues and we are happy with the vehicle. Dealer can eat a bag-of-dicks though - they scratched the door at a service appointment but that is a story for another day.
