1 Brake Sensor problem

Failure Date: 04/02/2017

"pre safe functions limited" message appeared on dashboard in Nov '16. Over couple months, auditory beep warning of being too close to something happened with no hazard nearby approx 6 times. On 4/2/17, while driving 35 mph on sunny day, auditory warning started (with no hazard nearby) then stopped when we stopped at traffic light. Beeping started again (with no hazard nearby) when we started driving, then car self-braked while driving at least 20 mph and cars around us started honking. Started driving again and car self-braked again. We pulled into a parking lot and turned off the car for a few minutes, called car dealer. Sensors in front did not appear dirty or blocked by anything. We were able to drive home 10 min without incident. Next day, car dealer reported it was a computer issue that they fixed by updating software. Paperwork reads "performed repair as per bulletin. " on 4/4/17, "pre safe functions limited" warning appeared again.
