I HAVE A 2012 CHEVY SONIC LT AUTOMATIC WITH THE 1.8 LITER. THE CAR STARTED HAVING PROBLEMS AROUND 45,000 MILES AND HAS GOTTEN WORSE OVER TIME.THE CAR ON COLD START UPS HAS A GRINDING SOUND. THIS GRINDING MOST OF THE TIME ONLY HAPPENS ON COLD START UPS BUT DOES AT TIMES HAPPENS ON WARM START UPS. THIS SOUNDS LIKE METAL AGAINST METAL AND IT RATTLES. THIS SEEMS TO HAPPEN UNTIL THE CAR IS FULLY STARTED AND RUNNING. I AM GETTING CONCERNED BECAUSE IT IS GETTING WORSE AND LOUDER. *TR
