VEHICLE SUDDENLY STOPPED CHANGING GEARS WHILE ON A MAIN ROAD WHERE SPEED LIMIT IS 55 MPH. TURNED ONTO A SMALLER COUNTRY ROAD, COULD NOT ACCELERATE MORE THAN 20 MPH, AND SLOWLY DESCENDED FROM THERE UNTIL FINALLY COMING TO A COMPLETE STOP. CRACKED RADIATOR CAUSED COOLANT LEAK INTO TRANSMISSION FLUID CAUSING MANY SYSTEMS TO FAIL. IN TURN, HAD TO REPLACE RADIATOR AND COMPLETELY REBUILD AND FLUSH TRANSMISSION SEVERAL TIMES ($4400 EXPENSE). HAD I BEEN ON A MAJOR HIGHWAY OR INTERSTATE WHEN THIS HAPPENED, THERE WOULD HAVE BEEN A MUCH MORE SERIOUS OUT COME. *TR

WHILE DRIVING 70 MILES AN HOUR ON THE HIGHWAY MY CAR SUDDENLY SHOT UP TO 4000 RPM AND WOULDN'T GO FASTER THAN 30 MILES AN HOUR. AFTER MY CAR WAS TOWED TO A LOCAL MECHANIC FRIEND OF MINE'S SHOP HE TOLD ME THE RADIATOR HAD CRACKED, LEAKED COOLANT INTO THE TRANSMISSION, FRIED THE TRANSMISSION AND TORQUE CONTROL VALVE, ALL VALVES AND SEALS, AS WELL AS BOTH CATALYTIC CONVERTERS. THE COST TO FIX WOULD BE $6000. NISSAN NEEDS TO PAY FOR THIS BECAUSE OF THEIR FACTORY DEFECT!!! *TR

CHECK ENGINE LIGHT CAME ON SO I TOOK IT TO AN AUTOZONE TO HAVE THE CODE READ. PO463, FUEL SENDING UNIT. DID SOME RESEARCH, CALLED NISSAN CORPORATE TO INFORM THEM OF THE ISSUE AND SEE IF I WAS ELIGIBLE FOR EXTENDED WARRANTY (WASN'T COVERED). NISSAN CORPORATE INFORMED ME THAT I WAS ELIGIBLE FOR ECM RELAY REPLACEMENT AT NO COST AT A DEALERSHIP, SO I TOOK THE CAR TO A DEALERSHIP THAT QUOTED ME LOWEST ON THE FUEL SENSOR REPAIR. THEY ASKED IF I HAD OTHER ISSUES AND I TOLD THEM THAT MY ENGINE SOMETIMES SOUNDED LIKE AN RC CAR. THEY OFFERED TO LOOK INTO IT, CALLED THIS AFTERNOON AFTER COMPLETING WORK ON SENSOR AND ECM RELAY TO INFORM ME THAT MY TIMING CHAINS WERE SHOT AND IN NEED OF IMMEDIATE REPLACEMENT. DID SOME MORE RESEARCH AND FOUND THIS IS A FREQUENT ISSUE IN NISSAN CARS, DECIDED TO FILE A REPORT. *TR

I WAS DRIVING ON A REGULAR ONE WAY STREET, WHEN MY CHECK ENGINE LIGHT CAME ON AND SMOKE CAME FROM UNDER THE HOOD. BY THE WAY, THIS HAPPENED ON MY WEDDING DAY. ANYWAYS, I HAD THE CAR TOWED TO A CAR SHOP TO FIND OUT THE RADIATOR BURST CAUSING THE COOLANT AND TRANSMISSION FLUID TO MIX, MY TRANSMISSION IS RUINED AND NEEDS TO BE REPLACED, MY RADIATOR NEEDS TO BE REPLACED, THE FLUIDS GOT INTO MY WATER PUMP WHICH ALSO NEEDS TO BE REPLACED. THE COMPLETE COST FOR DAMAGES IS $7500. NOW I AM OUT OF A CAR AND CANT TRADE IT IN BECAUSE IT IS NOT WORTH ANYTHING AT THIS POINT. AFTER READING ALL THE COMPLAINTS I SEE MANY OTHERS HAVE FACED THIS PROBLEM, THERE NEEDS TO BE A RECALL ON THESE FAULTY RADIATORS IN THE 2006 NISSAN XTERRAS. *TR

THERE WAS RECALL FOR VEHICLES SIMILAR IN YEAR AS MY CAR. THE RECALL WAS # 10V517000 AND WAS FOR THE "INTELLIGENT POWER DISTRIBUTION MODULE (IPDM)". I CALLED NISSAN AMERICA, AND ALTHOUGH MANY VEHICLES OF MY YEAR AND MAKE/MODEL WERE AFFECTED, MY VIN # WAS NOT INCLUDED. I SHOULD HAVE BEEN INCLUDED ON THIS RECALL BECAUSE THIS IS EXACTLY WHAT PART WAS DEFECTIVE AND EXACTLY WHAT I HAD TO PAY FOR TO GET FIXED. I WAS EVEN DRIVING WHEN IT STALLED OUT ON ME NUMEROUS TIMES AND I AM THANKFUL IT WAS NOT ON THE FREEWAY. IF POSSIBLE I WOULD LIKE TO BE ACKNOWLEDGED AND POTENTIALLY BE REIMBURSED BY NISSAN. *TR

WHILE ON A BUSINESS TRIP AWAY FROM HOME NOTICED THE HEATER STOPPED BLOWING WARM AIR. A FEW MINUTES LATER ENGINE TEMPERATURE SPIKED BUT THEN RETURNED TO NORMAL. 50 MILES LATER HEATER STARTED WORKING AGAIN. TOOK THE CAR TO A LOCAL MECHANIC AND DISCOVERED TRANSMISSION COOLER WITHIN THE RADIATOR HAD FAILED, ALLOWING THE RADIATOR COOLANT TO MIX WITH THE TRANSMISSION FLUID. PAID FOR THE REPLACEMENT OF THE RADIATOR/TRANSMISSION COOLER, SYSTEM FLUSH. HAD THE SYSTEM FLUSHED AGAIN 1 WEEK AFTER RADIATOR REPLACEMENT. TRANSMISSION NOW ACTING ERRATICALLY, PARTICULAR WHEN SHIFTING BETWEEN 3RD AND 4TH GEAR. INITIAL ASSESSMENTS BY MECHANIC SUGGESTS TRANSMISSION AND TRANSMISSION COMPUTER REQUIRE REPLACEMENT. COST OF REPLACEMENT EXCEEDS THE VALUE OF CAR EVEN THOUGH THE REST OF THE CAR IS IN EXCELLENT CONDITION. *TR

NISSAN WILL NOT STEP UP AND FIX THEIR MISTAKE, OUR CAR IS AT 87000 MILES AND THE COOLANT IS LEAKING INTO THE TRANSMISSION DUE TO HOW NISSAN CONFIGURED THEIR SYSTEM FROM THE YEARS OF 2006 - 2009. WHEN I SPOKE WITH [XXX] AT NISSAN CONSUMER AFFAIRS HE INTIMATED THAT NISSAN IS NOT AWARE OF THIS BEING A MAJOR ISSUE, BUT INTERESTINGLY ENOUGH STOPPED USING THIS CONFIGURATION IN 2010. THEY CLAIM THAT IT WILL NOT HAPPEN TO EVERY NISSAN, WE NEED MORE CONSUMERS TO COME FORWARD, SO THAT THIS WILL BECOME A "RECALL". THE SYSTEM IS FAULTY IT MAY NOT HAPPEN AT 80,000 / 90,000 / 100,000 , BUT COUNT ON IT HAPPENING AT SOME POINT. THIS IS A VERY EXPENSIVE REPAIR. IF NISSAN HAD COMMUNICATED TO US THAT THE WARRANTY COVERING THIS TRANSMISSION FAILURE WAS EXTENDED TO 80,000 BUT OF COURSE WHY WOULD THEY ADMIT TO A FAULTY SYSTEM, AND LET THEIR VALUED CUSTOMERS KNOW. SIMPLE THEY DO NOT VALUE THEIR CUSTOMERS, THEY LOST THIS GROUP. WAY TO GO NISSAN, SOMEWHERE DOWN THE LINE THIS WILL HURT YOU.

Official recalls

NISSAN IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.
Consequence & remedy
Consequence: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
Mar 3, 2010
NISSAN IS RECALLING CERTAIN MODEL YEAR 2006 AND MODEL YEAR 2008 FRONTIER, XTERRA AND PATHFINDER VEHICLES. THE MOLDED FUEL TANK SHELLS CAN DEFORM, CAUSING THE FUEL SENDER FLOAT ARM TO CONTACT AN EMBOSSMENT MOLDED INTO THE TANK SHELL CAUSING THE INSTRUMENT PANEL FUEL GAUGE TO SHOW THAT THE VEHICLE HAS APPROXIMATELY ONE QUARTER TANK WHEN THE FUEL TANK IS EMPTY.
Consequence & remedy
Consequence: THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL IN TRAFFIC, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE FUEL LEVEL SENDING UNIT INSIDE THE FUEL TANK WITH A NEW ONE THAT HAS A MODIFIED FLOAT ARM. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 22, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

IN THOSE AREAS OF THE COUNTRY WHICH USE HEAVY CONCENTRATIONS OF ROAD SALT IN THE WINTER, A MIXTURE OF SNOW/WATER AND SALT CAN ENTER INTO THE FRONT CRASH ZONE SENSOR (CZS) HOUSING. IF THIS OCCURS, THE CZS MAY INTERNALLY RUST RESULTING IN A SIGNAL INTERRUPTION. IF THIS HAPPENS, THE RED AIR BAG WARNING LIGHT WILL ILLUMINATE TO ALERT THE VEHICLE OPERATOR.
Consequence & remedy
Consequence: THIS ISSUE COULD RESULT IN THE NON-DEPLOYMENT OF THE DRIVER AND PASSENGER FRONT AIR BAGS IN A CRASH, INCREASING THE RISK OF PERSONAL INJURY.
Remedy: DEALERS WILL REPLACE THE FRONT CZS WITH A REDESIGNED SENSOR. THE RECALL BEGAN ON JANUARY 26, 2009. OWNERS IN THE OTHER STATES WILL RECEIVE EXTENDED WARRANTY COVERAGE FOR THE SENSOR TO 10 YEARS.

On February 29, 2012 the National Highway Traffic Safety Administration (NHTSA) received a letter petitioning the agency to conduct a defect investigation into MY 2005-2010 Nissan Pathfinder, Frontier, and Xterra vehicles [the subject vehicles] for automatic transmission failures related to failed transmission coolers.NHTSA conducted a comprehensive review of data related to this subject. Our report, documenting this review, is available in the document file for this defect petition.It will also be published in the Federal Register. Of the 2,505 referenced complaints, 638 relate to a potential hazard (unable to maintain speed, no motive power, engine stall) and 1,867 concern customer satisfaction issues including, but not limited to, repair cost, vehicle shudder and shake, and engine overheating.Taking into account the allocation of agency resources and priorities and the likelihood that additional investigation would result in a finding that an unreasonable risk to highway safety exists, we conclude that further investigation is not warranted and deny the petition.ODI Complaint ID numbers are referenced on the next page.
