Open the full vehicle complaint log (all categories)I WAS STOPPED AT A RED LIGHT WHEN MY VEHICLE ACCELERATED FORWARD AND I WAS ALMOST HIT BY SEVERAL CARS ACROSS THE INTERSECTION. I STEPPED HARDER ON THE BRAKE AND MANAGED TO STOP MY VEHICLE ALTHOUGH THE ENGINE WAS REVVING VERY HIGH. I MANAGED TO FIND AN OPENING IN TRAFFIC AND PULLED OVER. I TURNED THE CAR OFF AND RESTARTED IT. THE RPM'S WERE EVEN HIGHER NOW(OVER 5000). I IMMEDIATELY TURNED IT BACK OFF AND CALLED THE DEALERSHIP. I WAS TOLD IT WAS UNSAFE TO DRIVE AND TO HAVE IT TOWED TO THE DEALERSHIP. I HAD IT TOWED AND WAS JUST INFORMED BY THE SERVICE MANAGER AT THE DEALERSHIP THAT THERE IS NO RECALL FOR THIS ISSUE ( WHICH IS AN ACCELERATOR SENSOR). I THINK THIS COULD HAVE BEEN VERY SERIOUS. I AM EVEN MORE OUTRAGED BECAUSE OF THE FACT THAT MY DAUGHTER WAS IN THE CAR WITH ME. I HOPE YOU CAN YOU CAN PLEASE LOOK INTO THIS MATTER BEFORE THERE ARE ANY FATALITIES SOMEWHERE BECAUSE OF BUICK'S NEGLIGENCE( I HAVE REPORTED THIS OCCURRENCE TO BUICK SUPPORT).
