Consumer Description

I HAVE A 2003 CHEVY AVALANCHE Z71 WITH 59000 MILES. I NOTICED MY VEHICLE BEING VERY SLUGGISH THE DAY BEFORE. WHEN I LEFT FOR WORK, I COULD BARELY GET UP TO 50 MPH, IN ORDER FOR ME TO STAY AT 50 MPH I WOULD HAVE TO REACH 3000 RPM. AFTER I TURNED DOWN A SIDE ROAD, I COULD ONLY GET UP TO 20 MPH AT 3000 RPM. I PULLED OVER AND CALLED FOR HELP. I TOOK IT TO A CHEVY DEALERSHIP. THEY FOUND THE INTAKE GASKET WAS BAD WHICH CAUSED THE CONVERTERS TO FAIL AND CLOG UP THE Y PIPE. IT'S HARD TO BELIEVE THIS HAPPENED WITH ONLY 59000 MILES. I TAKE GREAT CARE OF MY AVALANCHE. I'VE READ ON FORUMS WHERE THERE IS A LOT OF PEOPLE THAT IS HAVING THE SAME PROBLEM WITH THE SAME TYPE OF TRUCK AND YEAR. THE DEALERSHIP REPLACED THE GASKET, BOTH CONVERTERS, Y-PIPE AND THE O2 SENSORS. *JB
