NHTSA Complaint #10396576 — 2000 MAZDA MPV

I PURCHASED AN MAZDA MPV IN 2007 FROM A CHEVY DEALERSHIP WHO SAID IT WAS IN GOOD WORKING CONDITION. IT WAS A 2000 MODEL. AS SOON AS WINTER CAME THE O2 SENSOR ON THE REAR BANK WENT OUT. PAID $400.00 TO THE DEALERSHIP TO REPLACE. IT LASTED ONLY A SHORT TIME. THE DEALERSHIP TOLD ME IT SHOULD LAST 100.000 MILES, SO THEY REPLACED IT AND ONLY CHARGED ME ANOTHER $400.00. TO DATE I HAVE HAD THE O2 SENSOR REPLACED A TOTAL OF FOUR TIMES. THE LAST TWO TIMES IT WAS AT A MAZDA DEALERSHIP. THEY ALSO TOLD ME IT SHOULD LAST 100,000 MILES. BUT EVERY TIME IT GETS BELOW 40 DEG F, IT FAILS, OR AT LEAST THE WARNING LIGHT COMES ON. I HAVE SPENT A TOTAL OF $1,200.00 IN REPLACING THE SENSOR. I KEEP DOING IT BECAUSE MY WIFE USES IT TO DRIVE OUR GRANDDAUGHTER TO DANCE CLASS AND I DON'T WANT THEM TO GET STRANDED ON THE ROAD WAY. I HAVE ALREADY LOST MY AUNT'S DAUGHTER TO A ROAD SIDE KILLER AND DON'T WANT IT TO HAPPEN ONCE MORE. *TR
