NHTSA Complaint #11271700 — 2011 CHEVROLET EQUINOX

AFTER HAVING FAILING O2 SENSORS AND CATALYTIC CONVERTER REPLACED (UNDER WARRANTY), NOW THE EXHAUST MANIFOLD IS CRACKED AND NEEDS TO BE REPLACED (NOT UNDER WARRANTY). THE O2 SENSORS AND CATALYTIC CONVERTER ARE ATTACHED TO THE EXHAUST MANIFOLD - COULD THEIR FAILURES BE WHY THERE IS A CRACK IN THE EXHAUST MANIFOLD!?!? MY VEHICLE WAS MAKING A VERY LOUD CLATTERING SOUND WHEN STARTING THAT WOULD GO AWAY AFTER A FEW MINUTES. I TOOK IT INTO THE CHEVY DEALERSHIP TO HAVE IT LOOKED AT, THEY SAY THE EXHAUST MANIFOLD IS CRACKED, AND EXHAUST IS LEAKING OUT. AT TIMES I COULD SMELL EXHAUST FROM THE INSIDE OF THE VEHICLE. ONLY 110,000 MILES ON THE VEHICLE.
