NHTSA Complaint #10811352 — 2003 NISSAN ALTIMA

MY NISSAN ALTIMA 2003 2.5 SL HAS BEEN EXPERIENCING LOT OF VIBRATIONS AND POWER LOST WHILE TRAVELING ON CITY STREETS AND HIGHWAYS, THE PROBLEM SEEMS GET WORSE ONCE YOUR EXIT THE HIGHWAY SITTING AT THE LIGHT THE CAR WANT IDLE. IT SEEMS LIKE IT WANTS TO SHUT OFF. NOW MY ENGINE CHECK LIGHT COMES ON SO I TOOK THE CAR TO TIRE PLUS CAR CARE, THEY TOLD ME THE ECM PROGRAM IS OUT DATED AND THE CODE THEY READ INDICATE NEW PROGRAM UPDATE AND POSSIBLE CATALYTIC CONVERTER PROBLEM, I TOOK MY CAR TO HAVE CATALYTIC CONVERTER CHANGED $400.00 DOLLARS THEY CLEARED THE ENGINE CHECK LIGHT AND SAID THIS SHOULD TAKE CARE OF THE VIBRATION AND ENGINE IDLE PROBLEM, ONE WEEK LATER ENGINE CHECK LIGHT CAME BACK ON, PROBLEMS OF VIBRATION HAS GOTTEN WORSE. I DECIDED TO TAKE THE CAR TO COURTESY NISSAN DEALER HAD THEM TO PERFORM DIAGNOSES SERVICE PERSON TOLD ME THE ECM WAS OUT DATED SO I PAID $120.00 DOLLARS TO UPDATE ECM PROGRAM, THE SERVICE PERSON TOLD ME THE VIBRATION IS BECAUSE MAYBE THE THROTTLE BODY (POWER VALVE SCREW) MAY BE GOING BAD AND IF POWER LOSS HAPPEN AGAIN I WILL NEED TO REPLACE THE THROTTLE BODY AT MY EXPENSE. NOTE: I HAVE DONE SOME RESEARCH AND FOUND NISSAN NORTH AMERICA (IN THEIR VOLUNTARY SERVICE CAMPAIGN PAPERS) REFERS TO IT AS THE POWER VALVE. THERE ARE SMALL SCREWS ON THE VALVE THAT COME LOOSE AND GET SUCKED INTO THE ENGINE. EVEN THOUGH THE 2002 THROUGH THE 2005 ALTIMA 2.5S' ALL HAVE THE QR25DE 2.5S ENGINE (WHICH IS THE EXACT SAME ENGINE WITH THE EXACT SAME PROBLEMS), THE MANUFACTURER, IN THIS CASE NNA IS ABLE TO LOOPHOLE THE LAWS CONCERNING A RECALL. LIKE IN MY CASE AND OTHER PEOPLE'S CASES, WE HAVE THE 2002 AND 2003 ALTIMA THAT IS EXPERIENCING THIS PROBLEM, BUT NNA WON'T TAKE CARE OF IT EVEN THOUGH THEY ARE AWARE OF IT AND CURRENTLY HAVE A VSC ON THE 2004 AND 2005 MODELS. *DT
