NHTSA Complaint #10216650 — 2002 NISSAN ALTIMA

I HAVE A 2002 NISSAN ALTIMA WITH 117,000 MILES. NISSAN USA REPLACED THE ENGINE AND THE CATALYTIC CONVERTER AS PART OF A RECALL JANUARY 06 WHEN THE CAR HAD 99600 MILES. LAST WEEK ON 1/24/08, THE CAR SHUT OFF WHILE DRIVING AND I WAS LUCKY TO PULL TO THE SIDE ON TIME TO PREVENT AN ACCIDENT. I TOOK THE CAR TO THE DEALER NISSAN COX IN THE BRONX THE FOLLOWING SATURDAY. THEY CHECKED THE CAR OUT AND TOLD ME THAT THE REASON WHY THE CAR SHUT OFF IS NOT RELATED TO THE PREVIOUS RECALLS. THEY TOLD ME THAT I NEEDED TO REPLACE MY THROTTLE AND CLEAN THE FUEL SYSTEM. I PAID $563 FOR THE LABOR ON 1/30/08. I DROVE THE CAR AROUND THE DEALER AND ONCE AGAIN THE CAR SHUT OFF BY ITSELF THEN I STARTED IT AGAIN AND WHILE DRIVING IT BACK TO THE DEALER THE ENGINE SURGED A COUPLE OF TIMES. I TOOK THE CAR TO THE DEALER AND THE NEXT DAY 1/31/08, I RECEIVED A CALL FROM THE SERVICE WORKER IN WHICH SHE TELLS ME THAT MY CATALYTIC CONVERTER IS BAD AND THAT'S WHAT'S CAUSING THE PROBLEM. I DON'T THINK IS FAIR THAT I HAD TO PAY $563 TO LATER FIND OUT THAT THE CAR HAD SOMETHING ELSE. ALSO, I DON'T UNDERSTAND WHY THE CATALYTIC GOT DAMAGED WHEN I RELIGIOUSLY SERVICED THE CAR FOR THE PAST TWO YEARS SINCE THE NEW ENGINE AND CAT WERE INSTALLED. THE DEALER TELLS ME THAT I'M NO LONGER COVERED BY THE WARRANTY AND THAT I NEED TO PAY ANOTHER $900 FOR PARTS AND LABOR. I THINK IM BEING RIPPED OFF BY THE DEALER AND NISSAN. I'VE READ HOW MUCH PROBLEMS THE 2002 ALTIMA HAS. CAN YOU GUYS PLEASE HELP ME. *TR
