NHTSA Complaint #10722713 — 2006 BUICK TERRAZA

I BOUGHT THIS VEHICLE IN FEB. 2015. ABOUT A WEEK AFTER PURCHASE I WAS GOING TO WORK ONE NIGHT AND THE VEHICLE SUDDENLY VEERED TO THE LEFT AND BRAKES LOCKED. THE STABILITY LIGHT THEN CAME ON. I PULLED OVER AND SHUT THE VAN OFF AND RESTARTED IT . NO LIGHT WAS ON THEN. ABOUT ONE MONTH LATER IT DID IT AGAIN. THIS TIME I WAS GOING ABOUT 50 MILES PH. A CAR BEHIND ME ALMOST HIT ME FROM BEHIND DUE TO THE SUDDEN STOP.ANOTHER MONTH WENT BY BEFORE IT STARTED DOING IT AGAIN. THIS TIME IT VEERED INTO THE PATH OF A SEMI TRACTOR TRAILER. I THEN CALLED THE DEALERSHIP AND THEY AGREED TO HAVE IT FIXED. I GOT IT BACK A WEEK LATER AND IT STILL HAS THE SAME ISSUE. THIS PROBLEM IS GOING TO CAUSE A MAJOR ACCIDENT AND HOPEFULLY NO ONE GETS KILLED!!!!!! BUICK NEEDS TO RECALL THESE VANS IMMEDIATELY.
