NHTSA Complaint #11091416 — 2016 MAZDA CX-9

WHEN DRIVING AT 35-50 MPH, MY 2016 MAZDA CX-9 PERIODICALLY BRAKES SUDDENLY WHILE DRIVING TO A SCRUBBING FORCEFUL STOP TOSSING THINGS OFF THE BACK SEAT, PLACING ME IN DANGER OF A REAR-END COLLISION. SOMETIMES A VERY QUICK BEEPING SOUND IS MADE, "B-R-A-K-E" APPEARS ON THE PANEL IN LARGE LETTERS --- THEN THE CAR AUTOMATICALLY COMES TO A SUDDEN STOP OR IT OCCURS WITH NO NOTICE. I HAVE TAKEN IT TO THE DEALER 3 OR 4 TIMES ONLY TO BE TOLD THAT THEY COULD FIND NOTHING WRONG. NO OBJECTS OF VEHICLES WERE IMMEDIATELY IN FRONT OF ME AND THE SENSOR WAS CLEAN WHEN THIS HAS OCCURRED.THIS SUDDEN STOPPING HAS OCCURRED ON THE FREEWAY, IN RUSH HOUR TRAFFIC AND ON CITY STREETS. THIS HAS OCCURRED AT LEAST 6 TIMES SINCE PURCHASED 03/17/17. I AM FEARFUL THAT THIS PROBLEM WILL RESULT IN INJURY OR DEATH TO ME AND OTHERS.
