2004 Nissan Titan

DRIVING ON FREEWAY - HEARD MODERATE BANG FROM BACK OF TRUCK AND THEN HOWLING BEGAN. DEALERSHIP DIAGNOSED AS REAR DIFFERENTIAL FAILURE AND QUOTES $2000 TO REPLACE. SERVICE MANAGER SHOWED ME A PILE OF TITAN AXLES IN ONE SERVICE BAY AWAITING PICKUP BY NISSAN. HE WAS AMAZED THAT MINE LASTED AS LONG AS IT DID (104560 MILES). EVEN THOUGH THIS IS A WELL KNOWN PROBLEM INSIDE THE NISSAN WORLD, NISSAN IS NOT WILLING TO MAKE ANY CONCESSIONS OR FIXING THIS AT A DISCOUNT. *TR

WHILE ATTEMPTING TO ACCELERATE, THE TACHOMETER HIT 3500 RPM AND THE ENGINE WENT FLAT. THERE WAS NO TYPE OF WARNING LIGHTS, IT WOULD REV UP TILL IT REACHED 3500 RPM AND THEN IT WOULD JUST CUT OUT LIKE IT HAD HIT THE REV LIMITER. I TOOK IT TO A NISSAN DEALER AND WAS TOLD THAT A LOW SPEED MISFIRE WAS THE ONLY CODE IN THE MEMORY AND THEY FELT THE PROBLEM WITH THE RPM WAS THE FUEL PUMP AS THEY HAD ALREADY REPLACED TWO 04 TITAN FUEL PUMPS. I CALLED BACK SEVERAL DAYS LATER AND WAS TOLD THE PROBLEM WAS NOT THE PUMP BUT THAT TWO OF THE CATALYTIC CONVERTERS WERE DAMAGED DUE TO THE MISFIRE. THEY HAD THE EXHAUST MANIFOLD UNHOOKED AND THE TRUCK RAN FINE. I HAD BOTH OF THE CONVERTERS REPLACED AND THE PROBLEM WAS STILL THERE. I TOOK IT TO ANOTHER NISSAN DEALER AND WAS TOLD THE FUEL PUMP WAS ONLY PUTTING OUT 34 PSI AT IDLE AND SHOULD BE 60. THEY ALSO SAID BECAUSE OF THE LOW FUEL PRESSURE THAT BOTH OF THE FRONT CONVERTERS WERE DAMAGED AND WERE NOW FAILING. THEY TOO STATED THEY HAD PROBLEMS WITH THE 04 FUEL PUMPS. I CONTACTED NISSAN (FILE NUMBER 6258543) AND ABOUT THIS AND RECEIVED NO HELP OTHER THAN BEING TOLD TO "HAVE A NICE DAY!' I HAVE SEARCHED THE INTERNET AND HAVE FOUND DOZEN OF INCIDENTS WHERE THIS HAS HAPPEN TO OTHER OWNERS AND THE PROBLEM SEEMS TO STEM FROM A FUEL PUMP PROBLEM ON THE 2004 TITAN. IN SOME CASES THE ENTIRE ENGINE HAD TO BE REPLACED WHEN THE CATALYTIC EXPLODED UPON THE RAW FUEL FROM THE MISFIRE REACHING THE CONVERTER. IT EXPLODED SENDING PIECES OF THE CONVERTER INTO THE ENGINE CYLINDER. NISSAN HAS NO TYPE OF SCREEN OR MESH IN THE CONVERTER TO CONTAIN ANY PIECES IN CASE OF A FAILURE. IF THIS HAD HAPPENED WHILE I WAS PASSING THE SEMI WITH ANOTHER VEHICLE COMING HEAD ON, THIS PROBLEM COULD HAVE RESULTED IN FATALITIES. THIS IS A PROBLEM THAT NISSAN NEEDS TO TAKE CARE OF BEFORE SOMEONE IS SERIOUSLY INJURED OR KILLED! *TR

REAR DIFFERENTIAL FAILURE. ATTEMPTING TO CROSS TRAFFIC WHEN REAR DIFFERENTIAL BROKE INTERNALLY AND HAD TO HAVE VEHICLE TOWED FROM SCENE (NEARLY HIT BY ONCOMING TRAFFIC). THIS IS A KNOWN CONSUMER PROBLEM, THAT HAS BEEN SERIOUSLY DENIED BY THE MANUFACTURER. SEVERAL PEOPLE HAVE COMPLAINED OF HAVING THESE UNITS REPLACED SEVERAL TIMES!! THE POTENTIAL EXISTS TO HAVE THE REAR WHEELS TO BECOME LOCKED UP IN THE EVENT OF A FAILURE!!!!!! WHY HAS NO INVESTIGATION BEEN OPENED?? SEVERAL CONSUMERS HAVE GONE TO AFTERMARKET EQUIPMENT REPLACEMENT BECAUSE OF THE HIGH FAILURE RATE. THIS PROBLEM IS HAPPENING IN 2004-2006 MODEL YEAR VEHICLES!!!! *TR
