NHTSA Complaint #10458714 — 2002 NISSAN ALTIMA

I PURCHASED THE VEHICLE ON 3/23/12. I HAD AN OIL CHANGE ON 3/26/12. THE ENGINE STARTED MAKING A RATTLING SOUND ON 4/20/12 AND A MECHANIC RECOMMENDED AN OIL CHANGE BECAUSE THE OIL WAS BLACK AND LOW. HE DID THE OIL CHANGE. THE NOISE WENT AWAY AFTER THE OIL CHANGE. THEN ON 5/6/12 THE RATTLING NOISE CAME BACK. I CHECKED THE OIL AND IT WAS EXTREMELY LOW. I ADDED 3 QUARTS. THEN ON 5/16/12, I CHECKED OIL AGAIN AND HAD TO ADD 1 1/2 QUARTS OF OIL. THERE ARE NO LEAKS UNDER THE CAR OR INSIDE THE HOOD. THE CAR IS CONSUMING AN EXCESSIVE AMOUNT OF OIL. I ONLY DRIVE THE CAR ABOUT 100 MILES PER WEEK AND SOMETIMES LESS. . AND THE "CHECK OIL" LIGHT NEVER COMES ON TO INDICATE THAT IT IS LOW. I NOW HAVE TO CHECK THE OIL EVERY OTHER DAY BECAUSE I AM WORRIED THAT IT WILL USE IT ALL. I HAVE TO KEEP QUARTS OF OIL IN THE TRUNK, IN CASE IT RUNS LOW AGAIN. THIS IS NOT NORMAL.
