221 reportsMY ENTIRE DRIVERS SIDE AND PASSNEGER SIDE FLOOR BOARD HAS ROTTED OUT COMPLETELY. IM TALKING I CAN PUT MY FOOT THROUGH IT. I HEAD ALL OF IT FALL OUT DRIVING DOWN THE I-90. THIS CAR IS RUST FREE FROM FLORIDA. THIS IS SUCH BS AND IS UNSAFE TO DRIVE.
I TOOK MY CAR IN FOR A SAFETY INSPECTION AND LEARNED THAT THE DRIVER'S SIDE FLOOR BOARD WAS RUSTED ENTIRELY THROUGH. THE ONLY THING BETWEEN ME AND THE ROAD WAS THE FLOOR MAT.

I TOOK MY CAR IN FOR A SAFETY INSPECTION AND LEARNED THAT THE DRIVER'S SIDE FLOOR BOARD WAS RUSTED ENTIRELY THROUGH. THE ONLY THING BETWEEN ME AND THE ROAD WAS THE FLOOR MAT. THE CAR DID NOT PASS INSPECTION AND WHEN I TOOK IT TO MY REGULAR MECHANIC HE WAS SHOCKED AT WHAT IT LOOKED LIKE. I TOOK IT TO A BODY SHOP AND LIKEWISE HE COULDN'T BELIEVE FROM THE LOOK OF THE CAR (WHICH HAS BEEN WELL MAINTAINED) THAT IT WOULD BE RUSTED OUT LIKE IT IS. THAT LED ME TO DO SOME RESEARCH AND LEARNED THAT THIS IS NOT AN UNCOMMON COMPLAINT AND THAT CLASS ACTION LAW SUITS ARE POPPING UP ALL OVER THE COUNTRY. I WANT TO LODGE MY COMPLAINT AND ADD IT TO THE OTHERS WHO HAVE NOTIFIED YOU OF THIS SERIOUS SAFETY RISK POSED BY THIS DEFECT.
THE FLOOR BOARD (PAN) UNDER DRIVER LEFT FOOT IS RUSTED. THERE IS A HOLE ABOUT 4 BY 8 INCHES BIG.
BOTH FLOOR BOARDS ARE RUSTED ON THE UNDERCARRIAGE. FRONT OF THE VEHICLE WE WERE CHANGING THE TIRES AND NOTICED THE SERIOUS RUSTING OUT OF BOTH FLOOR BOARDS.
I TOOK MY VEHICLE IN FOR AN OIL CHANGE AND THE GARAGE INFORMED ME THAT THE FLOOR BOARD ON THE DRIVER SIDE WAS RUSTED OUT SO BAD THAT YOU COULD TOUCH THE CARPET FROM THE BOTTOM. ALSO THE PASSENGER SIDE WAS RUSTED WITH A HOLE BUT NOT AS BIG AS THE DRIVER SIDE. I AM NOT SURE WHY NISSAN HAS NOT ISSUED A RECALL FOR THIS BEING THERE …

I TOOK MY VEHICLE IN FOR AN OIL CHANGE AND THE GARAGE INFORMED ME THAT THE FLOOR BOARD ON THE DRIVER SIDE WAS RUSTED OUT SO BAD THAT YOU COULD TOUCH THE CARPET FROM THE BOTTOM. ALSO THE PASSENGER SIDE WAS RUSTED WITH A HOLE BUT NOT AS BIG AS THE DRIVER SIDE. I AM NOT SURE WHY NISSAN HAS NOT ISSUED A RECALL FOR THIS BEING THERE ARE HUNDREDS OF COMPLAINTS FOR THIS. THIS PROBLEM IS A SAFETY ISSUE CONSIDERING IT WILL NOT PASS A SAFETY INSPECTION.
PASSENGER SIDE FLOORBOARD HAS RUSTED THROUGH AND MY UNDER-PADDING IS EXPOSED. THE CAR IS UNSAFE TO DRIVE.
THE FLOOR BOARDS ON BOTH THE DRIVER AND PASSENGER HAVE ROOTED OUT ALMOST COMPLETELY ON MY 2006 NISSAN ALTIMA. I HAVE NOTICED THIS A ABOUT A YEAR AGO AND IT HAS GOT INCREASINGLY WORSE SINCE.

THE FLOOR BOARDS ON BOTH THE DRIVER AND PASSENGER HAVE ROOTED OUT ALMOST COMPLETELY ON MY 2006 NISSAN ALTIMA. I HAVE NOTICED THIS A ABOUT A YEAR AGO AND IT HAS GOT INCREASINGLY WORSE SINCE. I CAN PUSH THE CARPET UP FROM UNDER THE VEHICLE AND FEEL VERY UNSAFE. I AM CAREFUL NOT TO PUT WEIGHT ON THE FLOORS WHILE ENTERING THE VEHICLE FOR FEAR I AM GOING TO PUT MY FOOT THROUGH THE FLOOR. THIS IS A VERY COMMON ISSUE DUE TO A FLAWED DESIGN IN THE DRAIN SYSTEM. THE FLOORBOARDS HOLD WATER WHICH MAY ACCUMULATE THROUGH THE DOOR WHILE RAINING AND SALT AND WATER FROM THE UNDER SIDE. PLEASE ISSUE A RECALL AND MAKE NISSAN FIX THESE VEHICLES THAT COULD STAY ON THE ROAD FOR MANY MORE YEARS. MY CAR HAS 109K MILES ON IT AND IS IN VERY GOOD SHAPE AND RUNS VERY WELL. I DON'T WANT TO HAVE TO DO THIS JOB MYSELF OR PAY 1,000 TO GET IT FIXED.
OBSERVED FRONT PASSENGER FLOORBOARD RUSTED/ROTTED COMPLETELY THROUGH WITH HOLE TO INTERIOR CABIN ALLOWING CARBON MONOXIDE / FUME INGRESS. OBSERVED FRONT DRIVER FLOORBOARD CORROSION AND STRUCTURAL FAILURE IN PROCESS. *TR
MY COMPLAINTS I HAVE WITH THIS CAR. MY FIRST IS THE FLOOR BOARD IS STAYING SOAKED WITH WATER AND MOLDING, WHICH IS NOT GOOD FOR PEOPLE WITH ALLERGIES TO MOLD AS IN THIS CASE, AND THE RUSTED FLOORBOARD PROBLEM. THE SECOND IS WITH THE OXYGEN SENSOR AND CATALYTIC CONVERTERS. *TR

307V527000 · Engine And Engine Cooling
Nov 14, 2007
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANKSHAFT POSITION SENSOR CAN OVERHEAT CAUSING A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.
Consequence & remedy
Consequence: IF THE INTERRUPTION IN THE SIGNAL FROM THE CRANKSHAFT POSITION SENSOR IS SO BRIEF THAT THE ELECTRONIC CONTROL MODULE (ECM) LOGIC DOES NOT HAVE TIME TO DIAGNOSE THE CONDITION, THE ENGINE MAY STOP RUNNING WITHOUT WARNING WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPROGRAM THE ECM FREE OF CHARGE. CERTAIN MY 2006 ALTIMAS WHICH HAVE BEEN PREVIOUSLY REMEDIED UNDER RECALL CAMPAIGN 06V223 (NISSAN R0606) ARE NOT INCLUDED IN THIS RECALL SINCE THE REPROGRAMMING FOR 06V223 ALSO INCLUDED THIS REPROGRAMMING.
