Consumer Description

WHILE ACCELERATING, ESPECIALLY UP INCLINES, I WOULD HEAR A KNOCKING SOUND, FEEL VIBRATIONS, THE CHECK ENGINE LIGHT WOULD COME ON AND THE ACCELERATION WOULD NOT WORK. I WOULD COAST FOR A LITTLE BIT (UP TO ABOUT A MINUTE) BEFORE THE ACCELERATION WOULD WORK AGAIN PROPERLY. THIS CAUSES A VERY HAZARDOUS SITUATION AS OTHER VEHICLE BEHIND ARE STILL ATTEMPTING TO ACCELERATE WHILE I CAN NOT. THIS HAS HAPPENED TO ME AT LEAST 5 TIMES IN THE LAST MONTH AND A HALF. THE MANUFACTURERS SERVICE CENTER THAT I TOOK THE VEHICLE TO SAID THAT THEY COULDN'T REPRODUCE THE ISSUE SO THERE IS "NOTHING WRONG" WITH THE VEHICLE.
