2011 Hyundai Elantra Electronic Stability Control Esc Service Brakes Problems

WHILE DRIVING ON A TWO LANE ROAD AROUND 45 MPH THE FRONT DRIVER'S SIDE WHEEL SUDDENLY AND REPEATEDLY LOCKED UP CAUSING THE TIRE TO SKID AND THE STEERING TO PULL TO THE LEFT. AT THE SAME TIME THE CAR SLOWED VERY QUICKLY TO 5 MPH AND ALMOST CAUSED THE DRIVER BEHIND ME TO SLAM INTO THE BACK OF MY CAR. I WAS NOT APPLYING THE BRAKE PEDAL DURING THIS INCIDENT. THIS IS A VERY DANGEROUS ISSUE AND NEEDS TO BE INVESTIGATED IMMEDIATELY. SIMILAR OCCURRENCES HAVE HAPPENED ABOUT ONCE PER MONTH IN THE PAST YEAR. I HAVE BROUGHT THE CAR TO HYUNDAI SERVICE AND EXPLAINED THE PROBLEM BUT THEY CANNOT DUPLICATE THE PROBLEM AND "FIND NOTHING WRONG". I HAVE NOTICED THAT WHEN THE PROBLEM IS HAPPENING IF I TURN OFF THE ESC THE PROBLEM WILL GO AWAY AND I CAN RESUME NORMAL DRIVING SPEED ONCE AGAIN. *TR

SINCE I BOUGHT THE CAR LATE FEB. 2011 (AFTER THEY RELEASE THE NEW MODELED CARS IN THE LAST DAYS OF THE PREVIOUS YEAR)...I HAVE COMPLAINED AND INQUIRED ABOUT AN OCCURRENCE THAT HAPPENS WITH THE BRAKES ON OCCASION THAT SEEMS TO BE TRIGGERING: VSM, ESC, TCS, ABS, BRAKE ASSIST AND/OR EBD SAFETY SYSTEMS UNDER NORMAL ROAD, TEMPERATURES, SPEEDS, BRAKE PRESSURE. THERE HAS BEEN AT BRAKE DELAYS, VERY LOUD GRINDING NOISE, AND AT TIMES PROVIDED A VIOLENT PUSH BACK AND PUMPING UNLIKE ANY NORMAL ABS SYSTEM AND THOSE TIMES WERE FEW BUT AGAIN UNDER NORMAL CONDITIONS NO SUDDEN BREAKING. THE GRINDING SOUNDS AND FEELS A BIT LIKE A SECOND AFTER YOU APPLY PRESSURE TO THE BRAKE AN ANCHOR DROPS ON THE ROAD AND BOUNCES AND GRINDS AGAINST MENTAL AND THE PAVEMENT. IT FEELS LIKE AN EMPTY BRAKE PAD (BUT IS NOT) AND STOP AS IF ONE ALSO. HOWEVER NOT ALL THE TIME AND WHEN THE BRAKES ARE NORMAL IT FEELS SAFE. HOWEVER, IT HAPPENS EVEN SLOWLY PARKING IN MY FLAT SMOOTH DRIVEWAY SOMETIMES (NO SAND I CHECK EVERYTIME). I HAVE AVOIDED MANY ACCIDENTS JUST BARELY WHEN THIS IS TRIGGERED AND IT MOST OFTEN CAUSING DOUBLE THE STOPPING TIME. I END UP INTO THE INTERSECTING STREETS BEYOND A STOP SIGN OR STOP LIGHT BY ABOUT HALF A CAR LENGTH. IT DOESN'T ALWAYS KICK IN RIGHT AWAY WITH BRAKE PRESSURE BUT TRIPS IT UP A SECOND LATER AND YOU HAVE TO ALMOST TRICK THE BRAKE AND STEERING TO GET CONTROL AND STOP IN TIME. THERE HAS BEEN TOO MUCH OF A PROCESS IN AN EFFORT TO CORRECT IT, OTHER ISSUES FOUND, AND MULTIPLE ACCIDENT CAUSED FROM IT ONE OF WHICH CAUSE A HOSPITAL VISIT AND AN INJURY LEAVING ME WILL A HEMATOMA AND CROOKED SMILE STILL. I NEED HELP AND MORE SPACE TO EXPLAIN. PLEASE EMAIL ME FOR DETAILS. *TR
