AUDI PRE SENSE, IS THE TECHNOLOGY AUDI USES FOR PREDICTIVE SAFETY. I HAVE EXPERIENCED SEVERAL AUDI PRE SENSE BRAKING MALFUNCTIONS. THE AUDI PRE SENSE IN MY VEHICLE WILL ABRUPTLY & VIOLENTLY COME TO A FULL STOP, WITH NO OBSTRUCTIONS OR HAZARDS ANYWHERE NEAR THE VICINITY OF THE CAR. FIRST OCCURRENCE HAPPENED ON 405 HIGHWAY HEADING NORTH ON SECOND OCCURRENCE HAPPENED ON 24TH ST IN REDMOND, HEADING NORTH ON NOVEMBER 27TH AT APPROXIMATELY 10:30 PM, DRIVING APPROXIMATELY AT 33 MPH..THE ROADS WERE CLEAR NO DRIVERS ANYWHERE IN MY VICINITY. THE ROAD WAS DRY. THE CAR COMES TO A VIOLENT SUDDEN STOP, RED HAZARD TRIANGLE APPEARS ON THE DASHBOARD, THESE TWO THINGS HAPPEN SIMULTANEOUSLY, THE SEATBELT ENGAGES & I'M SLAMMED FORWARD. THE BRAKES EMIT A LOUD GRINDING & CRUNCHING SOUND. IT TAKES SEVERAL SECONDS BEFORE I CAN BEGIN TO DRIVE AGAIN AS THE CAR IS LOCKED UP. THERE WERE NO OBSERVABLE OBSTRUCTIONS IN THE ROAD FOR IT TO MAKE THE CAR EMERGENCY BRAKE. WHEN THIS HAPPENED IT FELT LIKE I HAD HIT SOMEONE/SOMETHING, THAT WAS HOW VIOLENT THE STOP WAS. IT IS TERRIFYING AND DANGEROUS. ONCE I WAS ABLE TO DRIVE AGAIN, MY CAR DID NOT GO OVER ANY HAZARDS OR OBSTRUCTIONS AS THE VEHICLE THINKS THERE WAS, THERE WERE NO OTHER VEHICLES OR PERSONS IN MY VICINITY, THE ROAD WAS SMOOTH AND CLEAR. THE PRE SENSE HAS A MALFUNCTION RESULTING IN A BRAKING RESPONSE FAILURE. I TOOK THE CAR BACK TO AUDI SERVICES AND THEY KEPT THE CAR FOR 1 WEEK, THEY RAN DIAGNOSTICS & SAID THEY COULD NOTHING WRONG.
