I TOOK MY CAR IN FOR AN OIL CHANGE AND MY MECHANIC INDICATED THAT I HAD A RUSTY DRIVER'S SIDE FLOOR BOARD. HE SAID THAT HE WAS ABLE TO STICK HIS HAND THROUGH THE BOTTOM OF MY FLOORBOARD AND TOUCH MY DRIVER'S SEAT. THIS HAD ME VERY CONCERNED DUE TO THE POTENTIAL FOR THE DRIVER'S SEAT TO FALL OUT OF THE CAR WHILE I'M DRIVING. MY MECHANIC INDICATED THAT HE'S HAD THE SAME PROBLEM WITH AT LEAST 2 OTHER NISSAN ALTIMAS. BASED UPON THE NUMBER OF COMPLAINTS, IT LOOKS LIKE THIS IS A KNOWN ISSUE AND THAT NISSAN WILL NOT DO ANYTHING TO COMPENSATE. IT COST ME $550 TO FIX DUE TO THE EXTENT OF THE RUST. *TR

I WAS DRIVING DOWN THE ROAD GOING APPROXIMATELY 60 MPH, WHEN MY PASSENGERS AND I START SMELLING SOMETHING BURNING. WE LOOKED AROUND THE CAR DIDN'T SEE ANY THING, BUT THE SMELL GOT STRONGER AND MY SEAT WAS GETTING HOT. THEN ALL OF A SUDDEN THE CAR STARTED TO GET SMOKY AND FLAMES STARTED COMING UP FROM THE FLOOR AND THE BACK OF MY SEAT. I HURRIED UP AND PULLED OVER AND PUT IT OUT WITH A SHEET.

406V242000 · Engine And Engine Cooling
Jul 7, 2006
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANK ANGLE SENSOR IS AFFECTED BY TEMPERATURE VARIATIONS. UNDER CERTAIN DRIVING CONDITIONS, THESE VARIATIONS IN TEMPERATURE CAN BE LARGE ENOUGH TO CAUSE A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.
Consequence & remedy
Consequence: IF THE INTERRUPTION IN THE SIGNAL FROM THE 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. THE RECALL BEGAN ON AUGUST 21, 2006. 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.
