Phantom braking for no apparent reason. Worst occurrence was this morning driving home from work on cruise control, max speed cruise 73mph, suddenly my car braked on its own down to 59mph in 2 seconds. Very scary. My wrist hurts from that incident & my forehead almost hit the steering. Nothing in front & thank God no tailgating car behind me. This is not safe. It happens to me all the time but this was the scariest of all.
