“HELLO, I HAVE A 2005 BUICK TERRAZA CX AWD. MY ABS AND TRACTION CONTROL LIGHTS CAME ON AND WHEN IT DID THE VEHICLE STARTED TO APPLY THE BRAKES ITSELF PULLING THE VEHICLE TO THE LEFT WHILE DRIVING. I COULDN'T CONTROL THE VEHICLE. I STARTED READING UP ON THIS, AND IT APPEARS MANY OTHER OWNERS OF THIS VEHICLE BEEN HAVING THIS SAME UNSAFE PROBLEM OVER THE YEARS AND NO RECALL IS BEEN DONE. THIS IS A VERY SERIOUS ISSUE!!! I'M SURPRISE NO ONE HAS BEEN INVOLVED IN AN ACCIDENT AND BEEN KILLED. I ALSO NOTICE THIS HAS BEEN REPORTED MANY TIMES AS WELL TO THE MANUFACTURE AND THEY HAVEN'T DONE ANYTHING ABOUT IT BUT COME UP WITH EXCUSES TO THE OWNERS LIKE MYSELF. DO SOMEONE HAS TO BE KILLED BEFORE A RECALL IS DONE? I MYSELF IS GOING TO TAKE MY VIDEO I HAD FILMING ON MY WINDSHIELD WHEN THIS INCIDENT OCURRED AND SEND IT TO ALL THE MAJOR NEWS MEDIA GROUPS IN THIS COUNTRY AND PUT IT ON SOCIAL MEDIA AS WELL. THANK YOU FOR REVIEWING MY COMPLAINT, AND HOPEFULLY THE GOVERNMENT MAKE BUICK THE MANUFACTURE DO A SAFETY RECALL ASAP. I CAN'T UPLOAD MY VIDEO BECAUSE IT'S OVER THE MAXIMUM SIZE ALLOWED TO UPLOAD ON THIS WEBSITE.”
