221 reportsRUSTED FLOOR BOARD WITHIN 4 YEARS OF LIFE OF VEHICLE.
THE FLOORBOARDS HAVE RUSTED RIGHT THROUGH TO THE OUTSIDE. THIS SHOULD NOT HAPPEN WITH NORMAL WEAR. WE HAVE JUST BEEN ALERTED TO THIS BY THE MECHANIC AND IT IS SO ADVANCED HE ADVISES WE DON'T USE THE CAR! REPAIRING IT IS PROBABLY MORE THAN THE CAR IS WORTH!
I HAVE OWNED A 2006 NISSAN ALTIMA FOR THE LAST 6 YEARS THAT HAS 126,000 MILES ON IT. DURING A RECENT INSPECTION THE MECHANIC FOUND SEVERE RUSTING AND A SIGNIFICANT HOLE IN THE DRIVER'S SIDE FLOOR PAN; YOU COULD SEE THE INTERIOR CARPET FROM UNDERNEATH THE CAR.

I HAVE OWNED A 2006 NISSAN ALTIMA FOR THE LAST 6 YEARS THAT HAS 126,000 MILES ON IT. DURING A RECENT INSPECTION THE MECHANIC FOUND SEVERE RUSTING AND A SIGNIFICANT HOLE IN THE DRIVER'S SIDE FLOOR PAN; YOU COULD SEE THE INTERIOR CARPET FROM UNDERNEATH THE CAR. IT LOOKS LIKE THE FLOOR HAS BEEN ERODING FOR QUITE SOME TIME. AFTER SEARCHING FOR THIS ISSUE ONLINE, I LEARNED THAT THIS IS A COMMON PROBLEM WITH NISSAN ALTIMAS FROM 2002 TO 2006 RELATING TO A FAULTY DESIGN IN A DRAIN (THOSE WERE A NISSAN REPS OWN WORDS). I'M FRUSTRATED THAT THERE WERE NO RECALLS OR COMMUNICATIONS REGARDING THIS KNOWN ISSUE. I'D HOPE THAT NISSAN CAN BE COMPELLED TO BE TRANSPARENT AND FORTHCOMING WITH KNOWN ISSUES WHICH MAY BE A RISK TO CUSTOMERS' SAFETY.
IT SEEMS LIKE THIS IS A WIDESPREAD PROBLEM WITH OLDER ALTIMAS. APPARENTLY THE DRIVER AND PASSENGER SIDE FORMS A RUST PROBLEM WHICH CAN CAUSE ONE TO FEEL UNSAFE DRIVING THE CAR. THE IMAGE I ATTACHED SHOWS THE FLOORBOARD NOT ONLY RUSTING BUT COMING OFF, AND I CAN PUSH ON THE BOTTOM OF THE CARPET FROM THE BOTTOM OF MY CAR. NISSAN K…

IT SEEMS LIKE THIS IS A WIDESPREAD PROBLEM WITH OLDER ALTIMAS. APPARENTLY THE DRIVER AND PASSENGER SIDE FORMS A RUST PROBLEM WHICH CAN CAUSE ONE TO FEEL UNSAFE DRIVING THE CAR. THE IMAGE I ATTACHED SHOWS THE FLOORBOARD NOT ONLY RUSTING BUT COMING OFF, AND I CAN PUSH ON THE BOTTOM OF THE CARPET FROM THE BOTTOM OF MY CAR. NISSAN KNEW OF THIS PROBLEM SINCE 2008 AND HAS NOT OFFERED ANY OBVIOUS STATEMENTS NOR RECALLS. THIS IS POTENTIALLY DANGEROUS AND IS AN EXPENSIVE REPAIR (FOR BOTH SIDE FLOORBOARD REPLACEMENT, IT CAN COST 3000)
EXCESSIVE RUSTING OF THE FLOORBOARDS. A GAPING HOLE IS IN THE FLOOR GOING THROUGH TO THE OUTSIDE OF THE CAR. THIS IS FRUSTRATING BECAUSE THIS CAR HAS BEEN GARAGE KEPT AT HOME AND AT WORK.
TL* THE CONTACT OWNS A 2006 NISSAN ALTIMA. THE CONTACT STATED THAT THE VEHICLE FAILED INSPECTION DUE TO SEVERE FRAME CORROSION. THE INDEPENDENT TECHNICIAN DIAGNOSED THAT THE FLOORBOARD NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 101,980.
FLOORBOARD RUSTING/ DRIVER SIDE FLOORBOARD COMPLETELY RUSTED OUT HOLE HOLE APPROXIMATE SIZE 24 INCH WIDTH X 36 INCH LENGTH
FLOOR BOARD HAS RUSTED OUT ON THE FRONT PASSENGER SIDE.
I LOOKED UNDER MY CAR THIS EVENING AND FOUND A LARGE RUSTED OUT HOLE IN THE DRIVER'S SIDE FLOORBOARD. THE PASSENGER SIDE FLOORBOARD ALSO SEEMS TO BE RUSTING FROM THE INSIDE OUT.

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.
