NHTSA Complaint #10582929 — 2009 MERCEDES BENZ C63

AS I WAS DRIVING I HAD A LIGHT COME ON MY DASH TELLING ME I HAD LOW COOLANT AND THAT I NEEDED TO HAVE IT FILLED. THIS HAS HAPPENED A NUMBER OF TIMES SINCE MY SHORT OWNERSHIP OF THIS VEHICLE. FROM WHAT I UNDERSTAND THIS IS A SEALED UNIT AND SHOULD NOT BE LOSING ANTIFREEZE ANYWHERE. I HAD THE VEHICLE LOOKED AT AND I DO NOT HAVE ANY LEAKS WHATSOEVER. WHEN I ADD THE COOLANT, IT SEEMS TO BE FAIRLY LOW. I AM CONCERNED THAT I MAY HAVE SOME BIG ISSUES ON MY HANDS AND COULD POTENTIALLY HAVE A HYDRO-LOCKING OF THE ENGINE PROBLEM CREATING A MAJOR SAFETY ISSUE LEADING TO A CRASH. AFTER A BIT OF RESEARCH I AM FINDING THAT THE MB C63 HAS "HEAD BOLT" ISSUES LEADING TO THE LOSS OF COOLANT AND ENGINES BLOWING UP AND OR HYDRO-LOCKING. I FEAR THIS ISSUE MAY HAPPEN TO ME AND WOULD REALLY APPRECIATE THIS BEING LOOKED INTO AS I FEEL MB HAS A CERTAIN AMOUNT OF RESPONSIBILITY HERE WITH REGARDS TO THE SAFETY OF THEIR PATRONS. THANK YOU FOR HEARING ME. *TT
