NHTSA Complaint #10863752 — 2004 NISSAN ALTIMA

FOR THE 2ND TIME CAR RUNNING VERY ROUGH AND STALLING. HAD IT SERVICED SEEMS THE SPARK PLUGS WERE DESTROYED AND NOT FUNCTIONING. PAID OVER $500 FOR MECHANIC TO PUT IN NEW PLUGS NOW IT HAPPENED AGAIN. SEEMS THERE IS A VOLUNTARY SERVICE CAMPAIGN QR25DE POWER VALVE. CAMPAIGN ID P5202. A BOLT FROM MANIFOLD IS FALLING INTO CYLINDER AND BLOWING OUT SPARK PLUG AND CAUSING INTERNAL ENGINE DAMAGE, MY MECHANIC PUT CAMERA IN CYLINDER. CAR IS RUNNING BUT IT HAS ALREADY HAPPENED TO CYLINDER 1 AND 4. NEXT TIME MY 22 YEAR OLD DAUGHTER MAY NOT BE SO LUCKY ON HER HIGHWAY COMMUTE. HOPEFULLY THE LOCAL NISSAN DEALER CAN RECTIFY PROBLEM BEFORE THE PROBLEM BECOMES MORE SERIOUS. THE ENGINE LIGHT CAME ON THAT SAYS TO SERVICE ENGINE SOON, IT IS STILL ON...FROM WHAT I HAVE FOUND ONLINE SOUNDS LIKE POWER VALVE SCREWS ARE COMING OUT AND CREATING ENGINE DAMAGE.
