Consumer Description
I BOUGHT MY 2011 HYUNDAI SONATA BACK IN FEBRUARY 2012 FROM ENTERPRISE CAR SALES AND EVER SINCE I BOUGHT IT I BEEN HEARING A KNOCKING SOUND IN THE FRONT END OF MY CAR WHILE IM DRIVING FROM MAYBE 10MPH TO 40MPH. BUT ON THE HIGHWAY WHEN I REACH SPEEDS OVER 50MPH I DON'T HEAR ANYTHING. I HAVE TAKEN IT TO THE DEALER NUMEROUS OF TIMES I HAVE HAD CERTIFIED MECHANICS CHECK IT AND THEY TOLD ME IT COULD BE ONE OF THE MOTOR MOUNTS BUT THE DEALER NEVER WANTED TO CHANGE IT THEY KEPT TELLING ME THE CAR WAS FINE. NOW ITS GOING TO BE A YEAR LATER AND MY CAR HAS THAT SAME KNOCKING SOUND IN THE FRONT BUT NOW ITS EXTREMELY LOUD. I CAN FEEL THE KNOCKING THROUGH THE STEERING TOO SO NOW I DON'T KNOW WHAT TO DO. *TR
