I PURCHASED MY VEHICLE BRAND NEW IN 2007 AND HAVE HAD IT REGULARLY MAINTAINED SINCE THIS TIME. I WAS DRIVING DOWN THE HIGHWAY AT ABOUT 60 MPH, WHEN THE VEHICLE BEGAN TO SHAKE VIOLENTLY. I WAS IN FAIRLY HEAVY TRAFFIC AND HAD DIFFICULTY MAINTAINING CONTROL OF THE VEHICLE AS I STRUGGLED TO PULL IT TO THE SIDE OF THE ROAD. I HAD IT TOWED INTO MY LOCAL DEALERSHIP WHO INFORMED ME THAT THE RADIATOR HAD CRACKED AND COOLANT HAD WORKED IT'S WAY INTO THE TRANSMISSION. I AM BEING TOLD THAT I NEED TO REPLACE THE RADIATOR AND TRANSMISSION WHICH WILL COST ME $5500 IN PARTS AND LABOR. IN ADDITION TO THIS, TRANSMISSIONS FOR THIS VEHICLE ARE ON BACKORDER AND I MUST WAIT EVEN LONGER FOR THE REPAIRS. OF COURSE, I HAVE 95,000 MILES ON THE VEHICLE AND THAT MEANS I AM OUTSIDE OF THE WARRANTY COVERAGE. MY BIGGEST COMPLAINT IS THAT THIS PROBLEM IS LIKELY A MANUFACTURER DEFECT AND SERIOUSLY PUTS OWNERS AT RISK OF INJURY OR EVEN DEATH. I WISH NISSAN WOULD BE MORE ACCOMMODATING IN REIMBURSING THE REPAIRS AND WARNING OWNERS ABOUT THIS PROBLEM IN THE FUTURE. *TR

I HAVE A 2006 NISSAN XTERRA AND NOTICED IT WAS DRIVING ROUGH OFF AND ON. I TOOK IT INTO THE DEALERSHIP AS THERE WAS A RECALL ON THE ECM RELAY AND ASKED THEM TO CHECK THE ROUGH DRIVING. I WAS CALLED AND ADVISED THAT MY RADIATOR BROKE WHICH CAUSED FLUID TO LEAK INTO MY TRANSMISSION AND WOULD NEED TO REPLACE BOTH. I WAS QUOTED $9200.00 WHICH IS UNACCEPTABLE. I USE MY TRUCK STRICTLY FOR COMMUTING, DON'T EVEN USE 4WD. THE TRUCK ISN'T EVEN PAID OFF YET. THERE IS NO RECALL ON THIS, YET AS I DO RESEARCH I HAVE FOUND THAT THIS IS A COMMON PROBLEM, YET NISSAN IS DOING NOTHING ABOUT IT. I CALLED AAMCO AND WAS ADVISED IT WOULD COST $2800-3200 FOR THEM TO FIX AND THAT THEY SEE THIS WITH NISSANS WAY TOO FREQUENTLY. MY PERSONAL MECHANIC ADVISED HE CAN FIX IT FOR AROUND THAT SAME PRICE AS WELL. I DEPEND ON THIS VEHICLE FOR GETTING TO WORK AND SAFELY GETTING MY CHILDREN TO SCHOOL. WHAT A LET DOWN FOR SUCH AN EXPENSIVE PURCHASE. *TR

MY 2006 NISSAN XTERRA STARTED SHAKING VIOLENTLY WHILE DRIVING AT 40MPH ALL OF A SUDDEN, TO THE POINT I THOUGHT I HIT SOMETHING OR WAS DRAGGING A BRANCH, I STOP TO FIND NOTHING AND KEPT ON DRIVING, AND THE CART DID IT AGAIN, SO SCARED OF GOING ANY FASTER AND LOOSING CONTROL. I TOOK IT TO THE DEALERSHIP AND THEY INFORMED ME THAT DUE TO A DESIGN FLAW CRACKED RADIATORS ARE CAUSING COOLANT TO LEAK INTO THE TRANSMISSION AND MIX WITH THE TRANSMISSION FLUID. ONCE THE COOLANT (ANTIFREEZE) IS IN THE TRANSMISSION IT KILLS THE VALVES, SEALS AND TORQUE CONVERTER AND EVENTUALLY RENDERS THE ENTIRE TRANSMISSION USELESS. IT SEEMS TO BE A COMMON OCCURRENCE ON '05-'06 XTERRA. BUT I WAS NEVER INFORMED NOR OTHER XTERRA OWNERS. TO CORRECT THIS I HAVE TO REPLACE THE RADIATOR & TRANSMISSION AT AN OUTRAGEOUS PRICE. ALTHOUGH NISSAN HASN'T CONDUCTED A RECALL OR ACKNOWLEDGER THERE'S A PROBLEM, THEY DID EXTEND THE POWER TRAIN WARRANTY FROM 60K TO 80K. MY VEHICLE HAS 94K MILES, SO I'M HOPING MY EXTENDED WARRANTY COVERS IT. THIS IS VERY DANGEROUS, IMAGINE DRIVING AT 60MPH AND LOOSING CONTROL DUE TO STRONG SHAKING. I JUST CANT BELIEVE WITH THE OVERWHELMING AMOUNT OF PEOPLE COMPLAINING THEY HAVEN'T STARTED A RECALL. *TR

A COMMON PROBLEM WITH NISSAN PATHFINDER/XTERRA/FRONTIERS EQUIPPED WITH AUTOMATIC TRANSMISSIONS, IS THE RADIATOR FAILING AND LEAKING COOLANT INTO THE TRANSMISSION VIA A PORTION OF THE TRANSMISSION SYSTEM THAT PASSES THROUGH THE RADIATOR. THIS PROBLEM IS MOST COMMON WITH 2005 TO 2008 MODEL NISSANS. THE FIRST SIGN OF THIS FAILURE IS A SLIGHT VIBRATION AT 40-50 MPH WHEN THE VEHICLE SHIFTS FROM 4TH TO OVERDRIVE (5TH) GEAR. AT THIS POINT THE DAMAGE, APPARENTLY, HAS BEEN DONE. IN WORST CASE SITUATIONS THE VEHICLES CAN FALL INTO "SAFE MODE" CAUSING THE VEHICLE'S OPERATOR TO LOSE CONTROL DUE TO UNDESIRED TRANSMISSION OPERATION. BY VISITING MANY NISSAN OWNER FORUMS AND INTERNET SEARCH ENGINES, THIS IS A WIDE SPREAD PROBLEM FOR NISSAN OWNERS. IT HAS BEEN MY PERSONAL EXPERIENCE THAT NISSAN HAS MADE NO OFFER OF ASSISTANCE FOR MOST CUSTOMERS WITH THIS PROBLEM. I FEEL THAT THIS PROBLEM IS WIDESPREAD AND DANGEROUS AND IS A DESIGN FLAW BY NISSAN AND/OR ITS PARTS VENDORS AND SHOULD BE CORRECTED AT NO COST TO VEHICLE OWNERS. NISSAN SHOULD REPLACE RADIATORS ON ALL MODELS EFFECTED AND SHOULD REPLACE TRANSMISSIONS IN ANY VEHICLES THAT HAVE HAD THIS FAILURE. *TR

Oct 28, 2010

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.

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.

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.
