NHTSA Complaint #11287577 — 2010 GMC TERRAIN

IN SEPT. 2017, THE DEALER FIXED THE CATALYTIC CONVERTER B/C IT WAS UNDER A "SPECIAL WARRANTY" FOR FREE HOWEVER I HAD TO PAY $582 TO REPLACE THE CRACKED MANIFOLD WHICH CAUSED THE CONVERTER ISSUE. I RECENTLY WENT TO THE DEALERSHIP B/C THE CHECK ENGINE LIGHT CAME ON AGAIN, THE CATALYTIC CONVERTER IS STILL UNDER WARRANTY AND THEY HAVE TO FIX THE OIL CONSUMPTION PROBLEM THE IS UNDER A "SPECIAL COVERAGE" AND AGAIN I WAS TOLD THAT I HAD TO PAY FOR ANOTHER CRACKED MANIFOLD. I ASKED WHAT CAUSES IT AND WHY AND WAS TOLD THEY DID NOT KNOW BUT I BELIEVE IT MUST HAVE TO DO WITH THE ORIGINAL CATALYTIC CONVERTER ISSUE. I UNDERSTAND THAT THERE IS A SPECIAL COVERAGE TO FIX THE CC HOWEVER SOMETHING MUST BE CAUSING IT TO FAIL AND GM IS AWARE OF IT.
