SCHEDULED RECALL WORK ON CAR ON FRIDAY, WAS NOTIFIED THAT THERE WAS ACTUALLY THREE RECALLS ON MY CAR (WHICH I HAVE OWNED FOR ABOUT A YEAR, PURCHASED USED) THET NEEDED TO BE DONE AND THAT I NEED MY 30,000 MILE SERVICE DONE. $476 AND LATER THAT AFTERNOON, IGOT MY CAR BACK. I NOTICED THAT THE BRAKED SEEM A LITTLE TIGHT, BUT FIGURED THAT WAS PART OF THE SERVICE. THE NEXT DAY, SATURDAY, WHILE MERGING FROM ONE FREEWAY TO ANOTHER AT ABOUT 65 MILES PER HOUR, CAR SOUNDED LIKE IT CAUGHT A PIECE OF THIN METAL UNDER FRONT RIGHT QUADRANT OF CAR, AFTER ABOUT 15 SECONDS NOISE STOPPED AND NOTHING IN ROAD BEHIND ME. I NOTICE MY BRAKE LIGHT CAME ON. WHEN I TRIED TO CHANGE LANES, I REALIZE I HAD LOST THE POWER STEERING FUNCTION, THE BRAKES LAD LOOSENED UP (BUT FUNCTIONING) AND THE AIR CONDITIONING WAS NOW BLOWING HOT AIR. I REALIZE I HAD NO IDEA WHERE THE HAZZARD LIGHTS SWITCH WAS AND NIETHER I NOR MY PASSANGE COULD FIND IT. AFTER 2 MORE MINUTES PASSES GOING UP A SLOW INCLINE, THE CAR STARTED JERKING AT ROUND 55 MPH. AT THIS POINT THE BATTERY LIGHT CAME ON, AS WELL AS, THE "SERVICE ENGINE SOON". WELL NO KIDDING, SERVICE ENGINE SOON! PULLED INTO THE EMERGANCY LANE AND DROPPED MY SPEED TO BELOW 25 MILES PER HOUR AND THE CAR STOPPED JERKING. FORTUNANTLY, I WAS JUST ONE MILE FROM HOME AT THIS POINT. LIMPED HOME AND CALL DEALERSHIP. THE CAR HAD BEEN TOWED TO CROWN NISSAN IN BIRMINGHAM. I WAS ANNOYED THAT THE SERVICE MAN THAT TOOK MY CALL SHOWED NO EMPATHY WHEN I TOLD HIM WHAT HAPPENED ON THE FASTEST FREEWAY IN TOWN . ADDITIONALLY, I WAS ANGERED BY THE RECEPTIONIST WHEN SHE CAME BACK TO ME FROM BEING ON HOLD AND KNOWING MY PERDICTMENT, LAUGHING AND ASKING WHO I WAS ON HOLD FOR. *AK

MY CAR WAS UNATTENDED WHEN IT WAS STRUCK, MORE LIKE SIDESWIPED. THERE WAS A CREASE APPROXIMATELY 3/4 OF THE WAY OF THE LENGTH OF THE CAR. I AM NOT SURE HOW IT HAPPENED BUT THE ANGLE THE CAR WAS HIT, PERHAPS AT THE WHEELWELL SENT THE CAR ONTO THE SIDEWALK. I EQUATE THE "INCIDENT" WITH HITTING A POTHOLE. AFTER THE POLICE LEFT AND I TRIED TO REMOVE THE CAR FROM THE SIDEWALK POSITION AND PARK IT I HAD NO STEERING WHATSOEVER. THE STEERING WHEEL JUST WENT AROUND AND AROUND AND AROUND. I LEARNED THAT A KNUCKLE WAS BROKEN, A BEARING WAS BROKEN AND THE AXEL WAS BROKEN. HOW? I NO LONGER FEEL SAFE IN THIS CAR. WHAT IF I HIT A POTHOLE, WILL THE CAR LOOSE ITS STEERING AGAIN? *LA
PROBLEMS WITH VEHICLE'S STEERING SYSTEM.*MR SIX DAYS AFTER THE VEHICLE WAS PURCHASED THE CONSUMER RETURNED IT TO THE DEALER BECAUSE OF VIBRATIONS IN THE STEERING AT HIGHWAY SPEEDS.

I WAS DRIVING WHEN I ATTEMPTED TO MAKE A RIGHT TURN, MY STEERING WHEEL LOCKED UP, THE VEHICLE SKIDDED AND STALLED IN THE MIDDLE OF AN INTERSECTION. I WAS DRIVING AND MY 14 MONTH OLD WAS IN THE BACK SEAT. I HAD THE VEHICLE TOWED TO THE NEAREST DEALERSHIP. I FEW HOURS LATER I WAS CONTACTED BY THE ASSISTANT MANAGER OF THE SERVICE DEPARTMENT WHERE I WAS INFORMED THAT THE CRANK SHAFT POSITIONING SENSOR HAD GONE OUT. THE PART HAD TO BE ORDERED SO I WAS TOLD THAT I COULD BE WITHOUT MY VEHICLE FOR A DAY OR MAYBE EVEN A WEEK. I WAS INFORMED THAT THERE WERE OTHER VEHICLES IN THE SHOP WAITING FOR SIMILAR PARTS. MY VEHICLE HAS BEEN IN THE SHOP FOR 20 DAYS NOW AND I JUST KEEP GETTING THE RUN-AROUND. THIS IS PROBABLY A PART THAT WILL EVENTUALLY NEED TO BE RECALLED BUT I GUESS NISSAN IS WAITING FOR A TRADEGY TO OCCUR BEFORE THEY TAKE ACTION. *AK
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.

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.
