2002 Nissan Altima

2002 NISSAN ALTIMA BEGAN OVERHEATING, LOSING COOLANT RAPIDLY AND GAUGES INDICATED RAPID TEMPERATURE FLUCTUATIONS. UPON TAKING VEHICLE TO DEALER, VISUAL DIAGNOSTIC SUGGESTED A REPLACEMENT OF VALVE COVER GASKET. GASKET WAS REPLACED FOR APPROXIMATELY $300. OVERHEATING RESUMED AFTER REPAIRS IN ADDITION TO OVERHEATING, VEHICLE BEGAN PRODUCING WHITE SMOKE AS WELL AS MISFIRING UPON START-UP. COMPUTERIZED DIAGNOSTIC WAS THEN COMPLETED. DIAGNOSIS WAS A BLOWN HEAD GASKET. REPAIR COST WAS QUOTED AT $2100 PLUS TAXES. I DID RESEARCH ONLINE AND INVESTIGATION REVEALED THAT THE BLOWN HEAD GASKET WASN'T ISOLATED TO ME ALONE AND THAT THERE ARE MANY 2002 NISSAN ALTIMAS THAT BLOW THE HEAD GASKET AROUND 70,000 TO 90,000 MILES. MANY CUSTOMERS APPEAR TO HAVE TRIED TO CONTACT NISSAN BUT COMPANY WILL NOT OWN UP TO APPARENT DEFECT WITH THE MODEL. IT IS QUITE DIFFICULT TO BLOW A VEHICLE'S HEAD GASKET AND IT IS UNFAIR FOR A MODEL TO HAVE SUCH A MAJOR DEFECT AND THE CONSUMERS HAVE TO ASSUME RESPONSIBILITY AND COST OF REPAIRING THE PROBLEM - A MAJOR ENGINE OVERHAUL. TO PRESENT, NO INJURIES OR CRASHES HAVE RESULTED, HOWEVER, DEALER HAS WARNED THAT WITHOUT REPAIR, ENGINE PARTS MAY CONTINUE TO WARP AND MAY RESULT IN COMPLETE ENGINE FAILURE. *TR

TL*THE CONTACT OWNS A 2002 NISSAN ALTIMA. WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE FEELS AS IF IT WILL SHUT OFF, BUT IT REMAINS RUNNING. THE VEHICLE WAS TAKEN TO A LOCAL MECHANIC, WHO STATED THAT THERE MAY BE RECALLS ON HER VEHICLE. THE MANUFACTURER STATED THAT THERE WERE FOUR OPEN RECALLS ON HER VEHICLE AND ADVISED HER TO GO TO A DEALER FOR THE RECALL REPAIR. THE REPAIR WAS MADE, BUT THE FAILURE CONTINUED. THE CONTACT RETURNED TO HER LOCAL MECHANIC AND THE OXYGEN SENSOR WAS REMOVED. THE MECHANIC DISCOVERED THAT THE CATALYTIC CONVERTER HAD SHATTERED INTO PIECES AS EXPLAINED IN NHTSA CAMPAIGN ID NUMBER 03V084000 (ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE). THE FAILURE MILEAGE WAS 149,000.

CATASTROPHIC ENGINE FAILURE FOR NISSAN ALTIMA RELATED TO POWER VALVE/BUTTERFLY VALVE INTAKE MANIFOLD DESIGN. THIRD GENERATION ALTIMA'S QR25DE 4-CYLINDER AND VQ35DE 6-CYLINDER ENGINES HAVE UNFORTUNATELY BEEN AFFECTED BY A RECALL RELATED TO THE INTAKE MANIFOLD AND THE POWER VALVES, ALSO KNOWN AS THE BUTTERFLY VALVE. THE TECHNICAL SERVICE BULLETIN P5202 - DOES NOT MENTION ALL AFFECTED VEHICLES FOR PRODUCTION YEARS W SAME DESIGN. THIS HAS LEFT SOME OWNERS AFFECTED BY THE PROBLEM WITH NO RECOURSE/REMEDY FOR WHAT IN SOME CASES HAS AMOUNTED TO CATASTROPHIC ENGINE FAILURE. THE POWER VALVE IS A SERIES OF FOUR PLATES IN THE QR25DE 4-CYLINDER AND 6 PLATES IN THE VQ35DE 6-CYLINDER ENGINES, ONE PER CYLINDER. THE PLATES OPEN AND CLOSE SIMULTANEOUSLY TO ALLOW MORE AIR INTO THE COMBUSTION CHAMBER FOR INCREASED POWER. EACH PLATE IS HELD IN PLACE BY TWO SCREWS. THE SCREWS HAVE BEEN KNOWN TO COME LOOSE AS WELL AS THE PLATES AND ARE THEN INGESTED INTO THE ENGINE VIA THE INTAKE PORTS. PROBLEM IS INITIALLY EXHIBITED BY SES(SERVICE ENGINE SOON) LIGHT COMING ON AND/OR BLINKING. UPON OBD METER READING, CODE WILL BE P0304, OR SIMILAR WHICH IS RANDOM CYLINDER MISFIRE OR CYLINDER 4 MISFIRE. ELECTRODE ON SPARK PLUG HAS BEEN BENT CLOSED AS A RESULT OF THE POWER VALVE RETAINING SCREW VIBRATING LOOSE AND BEING INGESTED INTO THE ENGINE. THE SCREW THEN BOUNCES AROUND IN THE COMBUSTION CHAMBER, HITTING THE SPARK PLUG AND BENDING THE ELECTRODE SHUT, PREVENTING SPARK IN THAT CYLINDER. ADDITIONALLY, THE SCREW(S) AND PART OF THE BROKEN PLATES, IN SOME CASES HAVE MADE THEIR WAY THROUGH THE ENGINE AND INTO THE EXHAUST MANIFOLD AND THE CATALYTIC CONVERTER, THUS CAUSING THE CATALYTIC CONVERTER TO PREMATURELY DISINTEGRATE AS WELL AS BECOME INGESTED INTO THE ENGINE. FOR SOME REASON, NISSAN NORTH AMERICA HAS DECIDED TO NOT REMEDY ALL VEHICLES AFFECTED BY THIS ADMITTED FLAW OBVIOUSLY, THIS COULD CAUSE ENGINE FAILURE AT THE WRONG PLACE AND THE WRONG TIME, RESULTING IN SERIOUS BODILY HARM AND/OR FATALITY. *TR

MY 2002 NISSAN ALTIMA (2.5L) STARTED OUT WITH O2 SENSORS NEEDING REPLACED, THE OVERHEATING, NO COOLANT, LOOSING OIL, REPLACED CRANK SENSOR, HAD ALL RECALLS DONE ELECTRONIC CONTROL MODULE (ECM). NOW I AM LEFT WITH HAVING TO REPLACE MY ENGINE. THIS SEEMS LIKE A PROBLEM OUT OF MOST 2002 NISSAN ALTIMA WITH 2.5 ACCORDING TO THE INTERNET SEARCHES I HAVE COMPLETED. I FEEL NISSAN NEEDED TO RECALL THE WHOLE ENGINE. *TR

'SERVICE ENGINE SOON' LIGHT CAME ON & WOULD GO ON & OFF FOR THE PAST 3-4 MONTHS. I TOOK THE CAR TO A DEALER DUE TO A RECALL NOTICE ABOUT SOMETHING ELSE AND THE DEALER SAID THE CATALYTIC CONVERTER NEEDED REPLACED. THE EXHAUST SYSTEM SHOULD NOT BE FAILING ON THIS CAR. WHEN PICKING UP THE PART FROM THE DEALER, THE DEALERSHIP TOLD MY FATHER THAT THEY KEEP THIS PART (EXHAUST MANIFOLD) IN STOCK B/C THEY REPLACE SO MANY OF THEM. MY DAD ASKED IF THEY WERE GOING TO RECALL THE PART, THE NISSAN SERVICE MGR SAID NO. THE CATALYTIC CONVERTER SHOULD NOT BE CRACKING OR NEEDING TO BE REPLACED. I GOT THE PART ($400) AND MY MECHANIC IS FIXING IT TODAY. *TR
