NHTSA Complaint #10500806 — 2011 CHEVROLET EQUINOX

I BOUGHT MY 2011 EQUINOX LATE 2011. I HAVE HAD PROBLEMS ON AND OFF WITH THE ENGINE. FIRST IT STARTED MAKING AN AWFUL RACKET WHENEVER IT WAS FIRST STARTED. SOMETIMES ONLY ONCE A WEEK OR SO, SOMETIMES 2-3 TIMES A DAY. CHRISTMAS DAY 2012, WHILE LOADING THE VEHICLE WITH GIFTS AND SUCH I HAD STARTED IT SO THAT IT WOULD BE WARM WHEN WE WERE DONE. BUT BEFORE WE WERE DONE THE CAR STARTED TO SPUTTER AND ACT LIKE IT WAS OUT OF FUEL. I TURNED IT OFF AND AFTER I RESTARTED IT RAN FINE BUT ENGINE LIGHT WAS ON. LIGHT WENT OFF AFTER ABOUT 50 MILES. FROM CHRISTMAS 2012 TO FEBRUARY 20, 2013 THAT SPUTTERING HAPPENED OCCASIONALLY AND THEN TURNED INTO A LITTLE WORSE OF AN ISSUE AND MY ENGINE POWER REDUCED MESSAGE STARTED COMING ON AND I'D HAVE TO STOP AND RESTART THE CAR BEFORE IT WOULD QUIT.THE CAR WOULD BE 'SPUTTERING' OR FEEL AS THOUGH I WAS RUNNING OUT OF GAS. IT GOT TO WHERE WHEN THE ENGINE POWER REDUCED MESSAGE CAME ON, BEFORE I COULD EVEN PULL OVER TO SHUT IT OFF THE 'SPUTTERING' WAS SO BAD THAT MY CHECK STABILITRAC MESSAGE WOULD COME ON TOO. I NOTICED THAT MY MPG HAD WENT DOWN ALSO. 2-20-13, I PARKED THE CAR AND DIDN'T DRIVE IT AGAIN UNTIL THE DEALERSHIP COULD LOOK AT IT. I TOOK IT TO THE DEALERSHIP ON 2-26-13 AND I GOT IT BACK TODAY 2-28-13. THEY REPLACED THE THROTTLE BODY AND SOME OF THE WIRING FOR THE THROTTLE BODY AND IT RUNS LIKE A DREAM (SO FAR ANYWAY). IN FACT, I'M NOT SURE THAT IT EVER RAN THIS WELL THE ENTIRE TIME I'VE OWNED IT. *TR
