IllustrationFRONT FLOOR BOARDS ARE RUSTED THROUGH. DIDNT NOT NOTICE UNTIL AN INSPECTION WAS DONE. FIND THIS VERY ALARMING AS IT CAN BE UNRECOGNIZED WHEN STEPPING ON IT FROM INSIDE, AS THE CARPET HIDES AND SUPPORTS THE PARTIAL BODY WEIGHT WHEN STEPPING INTO THE VEHICLE. EXTREMRELY DANGEROUS FOR ANYBODY IN FRONT SEATS.

I PURCHASED MY CAR IN 2013 AS A USED 2002 NISSAN ALTIMA. THIS PAST JUNE OF 2015, MY MECHANIC NOTICED LARGE RUSTED OUT AREAS BEHIND EACH FRONT TIRE ON BOTH THE PASSENGER AND DRIVER SIDE OF THE UNDERCARRIAGE.

I PURCHASED MY CAR IN 2013 AS A USED 2002 NISSAN ALTIMA. THIS PAST JUNE OF 2015, MY MECHANIC NOTICED LARGE RUSTED OUT AREAS BEHIND EACH FRONT TIRE ON BOTH THE PASSENGER AND DRIVER SIDE OF THE UNDERCARRIAGE. THE DRIVER SIDE WAS RUSTED SO BADLY THAT ONE COULD EASILY TAKE CHUNKS OF RUSTED UNDERCARRIAGE OFF. I QUICKLY NOTICED A LARGE HOLE, REALIZING THAT WITHOUT CARPET BENEATH MY FEET I WOULD HAVE HAD MY LEFT FOOD THROUGH TO THE GROUND. AFTER MUCH RESEARCH, I FOUND THAT THIS IS AN ALL TOO FREQUENT OCCURANCE IN NISSAN ALTIMAS MADE IN 2002-2006, AND NISSAN REFUSES TO RECALL THESE VEHICLES AND/OR PAY FOR DAMAGES. WITH THESE FACTS IN MIND, ONE CAN SEE THAT THIS IS CLEARLY NOT AN ISSUE OF POOR CARE AND MAINTENANCE BY THE OWNER, NOR CAN IT BE BLAMED ON SALT AND CHEMICALS ON THE ROAD IN SNOWY AREAS. THIS ISSUE WAS UNSAFE TO MYSELF AND MY PASSENGERS. IF THE RUST HAD SPREAD, IT COULD HAVE CAUSED DAMAGE TO OTHER AREAS OF THE CAR, RISKING PERMANENT DAMAGE, AN UNSAFE VEHICLE ON THE ROAD, AND CAUSING POTENTIAL HARM TO MY PASSENGERS AND MYSELF. THE REPAIR FOR THIS SAFETY ISSUE DID NOT COME AT A LOW PRICE, AND THE SCENARIO IS ETERNALLY FRUSTRATING. I WILL NEVER BUY A NISSAN ALTIMA AGAIN, AND WILL CONTINUE TO WARN FRIENDS AND FAMILY AGAINST PURCHASING NISSANS.

UPON FURTHER INSPECTION, NOTICED EXCESSIVE RUST THAT HAS LEFT A HOLE THAT GOES THROUGH AND REACHES THE INTERIOR CARPET. THE SURROUNDING AREA IS VERY SOFT AND BRITTLE, SAME ON DRIVERS SIDE. CONCERNED ABOUT WEAKENING STRUCTURE OVERALL ESPECIALLY SEAT PLACEMENT, AND POSSIBLE INJURIES CAUSED BY NOT HAVING A PROTECTIVE SURFACE FROM THE OUTSIDE ROAD.
FLOOR PANELS RUSTING OUT. HAD CAR IN FOR SERVICE AND MECHANIC TOLD ME THERE WAS MAJOR RUST IN THE FLOOR BOARDS AND SHOULD BE ADDRESSED SOON.

THE FLOOR BOARDS ON THE PASSENGER AND DRIVER SIDE FRONT HAVE RUSTED THROUGH.
Official recalls
507V527000 · 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. THE RECALL BEGAN ON DECEMBER 31, 2007. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
03V455000 · Engine And Engine Cooling
Nov 17, 2003
ON CERTAIN PASSENGER VEHICLES, THE CIRCUIT BOARD FOR THE CRANK POSITION SENSOR OR CAM POSITION SENSOR MAY HAVE AN IMPROPER SOLDER JOINT DUE TO SOLDER DEFORMATION CAUSED BY HEAT STRESS ACCELERATED BY THE EXISTENCE OF FLUX RESIDUE DURING THE SOLDERING PROCESS.
Consequence & remedy
Consequence: THIS COULD CAUSE THE "SERVICE ENGINE SOON" WARNING LIGHT TO COME ON, CREATE A NO START CONDITION, CAUSE REDUCED ENGINE POWER, OR CAUSE THE ENGINE TO STOP RUNNING WITHOUT WARNING DURING VEHICLE OPERATION, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL REPLACE THE CRANK POSITION SENSORS. CAMSHAFT POSITION SENSOR(S), AND IN SOME CASES, THE VARIABLE TIMING CONTROL SENSOR(S). VEHICLES INVOLVED IN A PREVIOUS RECALL CAMPAIGN, 01V357, ARE ALSO INCLUDED IN THIS NEW CAMPAIGN. THE REPLACEMENT SENSORS USED IN THAT CAMPAIGN ARE ALSO AFFECTED. OWNER NOTIFICATION BEGAN ON DECEMBER 22, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261 OR INFINITI AT 1-800-662-6200.
03V251000 · Fuel System, Gasoline:storage:tank Assembly
Jul 14, 2003
ON CERTAIN PASSENGER VEHICLES ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF ALASKA, COLORADO, CONNECTICUT, IOWA, IDAHO, ILLINOIS, INDIANA, KANSAS, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, MONTANA, NORTH DAKOTA, NEBRASKA, NEW HAMPSHIRE, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, SOUTH DAKOTA, UTAH, VERMONT, WISCONSIN, AND WYOMING. AT EXTREMELY COLD TEMPERATURES, MOISTURE IN THE FUEL TANK COULD FREEZE AND FORM ICE CRYSTALS. THESE ICE CRYSTALS MAY OBSTRUCT THE SUCTION OPENING OF THE FUEL PUMP.
Consequence & remedy
Consequence: THIS CAN PREVENT THE SUPPLY OF FUEL TO THE ENGINE AND CAUSE THE ENGINE TO STOP, WHICH COULD RESULT IN A CRASH WITHOUT WARNING.
Remedy: DEALERS WILL INSTALL A SCREEN AT THE SUCTION OPENING OF THE FUEL PUMP TO PREVENT ICE CRYSTALS FROM BLOCKING THE OPENING. OWNER NOTIFICATION BEGAN ON AUGUST 18, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-333-0829.
03V084000 · Engine And Engine Cooling:exhaust System:manifold/header/muffler/tail Pipe
Mar 11, 2003
ON CERTAIN VEHICLES EQUIPPED WITH THE 2.5 LITER ENGINE, THE EXHAUST PIPE HANGER PIN MAY CATCH DEBRIS FROM THE ROAD THAT COULD BE IGNITED BY CONTACT WITH THE MAIN CATALYST. ALSO ON 2002 ALTIMA AND SENTRA VEHICLES, CERTAIN ENGINE OPERATING CONDITIONS MAY CAUSE THE PRE-CATALYST TO OVERHEAT AND DAMAGE THE CATALYST SUBSTRATE.
Consequence & remedy
Consequence: EITHER OF THESE TWO CONDITIONS COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REMOVE THE PROTRUDING PORTION OF THE EXHAUST PIPE HANGER PIN. IN ADDITION TO THE CORRECTIVE ACTION, IN ORDER TO REDUCE THE RISK OF FIRE IN THE EVENT OF POOR OR IMPROPER MAINTENANCE THAT COULD RESULT IN OIL SPILLAGE, HEAT SHIELD(S) WILL BE INSTALLED ON THE PRE-CATALYST AND EXHAUST TUBE. OWNER NOTIFICATION BEGAN ON JULY 28, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT NISSAN AT 1-800-647-7261. NISSAN RECALL NOS. R3007, R3014, R3015, R3016, R3017. ALSO ON 2002 ALTIMA AND SENTRA VEHICLES, CERTAIN ENGINE OPERATING CONDITIONS MAY CAUSE THE PRE-CATALYST TO OVERHEAT AND DAMAGE THE CATALYST SUBSTRATE. IF SUBSTRATE PARTICLES ENTER THE COMBUSTION CHAMBER, THEY COULD SCORE THE CYLINDER WALLS, RESULTING IN INCREASED OIL CONSUMPTION. IF THE ENGINE OIL LEVEL IS NOT CHECKED ON A PERIODIC BASIS AND DROPS BELOW THE LOW LEVEL, AND THE DRIVER CONTINUES TO OPERATE THE VEHICLE IGNORING NOTICEABLE ENGINE NOISE, ENGINE DAMAGE MAY OCCUR WHICH COULD RESULT IN A FIRE. THE PRE-CATALYST WILL BE TESTED TO ENSURE IT IS WORKING PROPERLY AND REPLACED IF NECESSARY. IF DAMAGE IS FOUND INSIDE THE PRE-CATALYST, IT WILL BE NECESSARY TO REPLACE THE ENGINE.
