NHTSA Complaint #10541718 — 2004 GMC YUKON

MY CAR BEGAN TO HAVE A BUILD UP OF SLUGS AND BEGAN LOOSING OIL PRESSURE AND COOLANT AND NEEDED OIL ADDED AND COOLANT FREQUENTLY. OIL PRESSURE FLAT-LINED IN JANUARY OF 2012 AND IT WAS TAKEN TO MY MECHANIC. THE SLUGS WERE CLEANED AND A NEW OIL PUMP WAS PLACED BECAUSE OF THE BUILD UP OF SLUGS. I WAS ADVISED TO CHANGE THE OIL FREQUENTLY TO CLEAN THE SLUG OUT BUT IT CONTINUED TO BUILD UP AND THE MYSTERY OF LOOSING COOLANT OIL PRESSURE HAS BOTTOMED OUT TWO MORE TIMES AND I FOUND A ARTICLE ON THE INTERNET THAT A NUMBER OF GMC VEHICLES INCLUDING MINE WERE BUILT WITH DEFECTIVE CYLINDER HEADS DUE TO CRACKS OVER TIME WHICH ALLOWS COOLANT TO LEAK INTO ENGINE AND MIX WITH THE OIL WHICH BUILDS UP SLUG. I WANT TO KNOW WHY A RECALL DOES NOT EXIST. THIS HAS COST ME SEVERAL THOUSANDS OF DOLLARS....I NEED GMC TO MAN UP TO THE PROBLEM AND FIX IT.*JB
