NHTSA Complaint #10318349 — 2003 NISSAN ALTIMA

MY 2003 NISSAN ALTIMA STARTED MAKING A KNOCKING SOUND ON THE ENGINE AND RUNS ROUGH. I TRIED USING FUEL SYSTEM CLEANER BUT IT DID NOT WORK. I ALSO TRIED OIL TREATMENTS AND CHANGING THE OIL BUT NON WORKED. I TOOK TO A NISSAN CERTIFIED MECHANIC AND TOLD ME INTAKE VALVE SCREWS WERE LOOSE AND CREATING A KNOCKING SOUND THAT THE BUTTERFLY IS HALF OPEN CAUSING THE CAR TO IDLE ROUGHLY. THE MECHANIC ALSO SAID THE THIS HAPPENS ALOT WITH THIS CARS, ALTIMAS AND SENTRA AND THAT THERE IS A RECALL FOR 2004 AND 2005 MODELS BUT NOT 2003 EVEN IF IT HAS THE SAME ENGINE. HE ALSO INFORMED ME THAT IF I DON'T GET IT FIXED THE IT WILL BREAK MY ENGINE AND COULD CAUSE AN ACCIDENT. ON THE SAME CAR I ALSO HAD TO PAY FOR A CRANK SENSOR THE FAILED ON ME. NISSAN SAID THE SAME THING, RECALL ON THE 2004 AND 2005 BUT NOT 2003. IT CAUSED MY CAR TO STALL AND RUN ROUGHLY. TOOK IT TO NISSAN AND THEY SAID NOTHINGS WRONG AND TAKE IT BACK TO THEM WHEN THE CHECK ENGINE LIGHT TURNS ON. AFTER A MONTH IT DID TURN ON. LUCKILY HAVE WARRANTY BUT THEY STILL CHARGE ME. PLEASE HELP, I'M NOT LOOKING FOR SOMEONE TO REPLACE MY CAR JUST TO HAVE NISSAN FIX WHAT THEY MESSED UP ON. *TR
