NHTSA Complaint #10893622 — 2010 GMC TERRAIN

CHECK ENGINE LIGHT HAS ILLUMINATED MULTIPLE TIMES. A ROUGH IDLE WAS INITIAL INDICATION SOMETHING WAS WRONG. I HAVE HAD THE VEHICLE TESTED MULTIPLE TIMES AND HAVE BEEN TOLD FROM DEALERSHIP AND OTHER MECHANICS THAT IT IS A TIMING ISSUE. THE VEHICLE WILL START AND DRIVE. SAFELY PROBLEM IS WHILE DRIVING THROUGH A BUSY TWO WAY INTERSECTION, AFTER COMING TO A COMPLETE STOP, THE VEHICLE WOULD NOT ACCELERATE AS NEEDED ALMOST LEADING TO AN ACCIDENT. UNDER NORMAL WORKING CONDITION I WOULD HAVE HAD NO PROBLEM MAKING IT THROUGH THE INTERSECTION IN A REASONABLE AMOUNT OF TIME. IT VERY SLOWLY PUTTERED THROUGH THE INTERSECTION WHILE I HAD THE ACCELERATOR PUSHED TO THE FLOOR BOARD AND AFTER FINALLY CROSSING THE INTERSECTION BEGAN TO ACCELERATE AT AN UNEXPECTED SPEED. I BEGAN TO ACCELERATE SO UNEXPECTEDLY THAT I TEMPORARILY LOST CONTROL OF THE VEHICLE AND CROSSED INTO THE INCOMING LANE OF TRAFFIC.
