2000 NISSAN ALTIMA Engine And Engine Coolingcooling System Problems

2000 NISSAN ALTIMA GXE HAS A FAULTY INTAKE MANIFOLD GASKET. THE PROBLEM STARTED A COUPLE OF YEARS AGO. MY CAR SHAKES WHILE IDLE AND THE RPMS GAUGE MOVES UP AND DOWN WHILE IDLE. I TOOK IT TO THE DEALER TO HAVE IT REPAIRED AND THEY REPLACED SPARK PLUGS, KNOCK SENSOR. AFTER THAT, THE SAME THING HAPPENED A FEW MONTHS LATER. TOOK MY VEHICLE TO THE SAME DEALER AND THEY NOW SAY THE INTAKE MANIFOLD GASKET IS LEAKING. I AM HAVING THE SAME PROBLEM BUT A DIFFERENT REASON EVERY TIME I GO TO THE DEALER TO FIX. WILL LITTLE RESEARCH I HAVE FOUND SEVERAL COSTLY COMPLAINTS REGARDING THIS SAME PROBLEM. WHAT IS THE NEXT STEP FOR CONSUMERS THAT ARE BEING RIPPED OFF BY THE NISSAN CORPORATION? *TR

WHEN DRIVING, GAUGES SUDDENLY STOP WORKING. THE TACHOMETER, ENGINE TEMPERATURE GAUGE, FUEL GAUGE FREEZE IN PLACE. THE SPEEDOMETER REGISTERS THE MAX AND THE DIGITAL ODOMETER WENT TO ZERO. *AK

WHILE DRIVING ON INTERSTATE 75 AT SPEED OF 75 MPH VEHICLE ENGINE SHUT OFF, VEHICLE WAS TOWED TO DEALER LOCATION WHEREBY SERVICE DEPT. INDICATED THE OVERHEATING WAS CAUSED BY DRIVING IN FLOODED CONDITION WHEN IN TRUE FACT THERE WAS NOT MORE THAN 1" OF WATER ON THE HIGHWAY THAT AFTERNOON. SERVICE DEPT. ANALYSIS WAS DIAGONISED AS DRIVING IN FLOODED CONDITIONS HENCE CAUSING AT 75 MPH THE RADIATOR FAN BLADE TO BE PUSHED BACK OVER 3-4" TOWARDS THE RADIATOR CAUSING THE PLASTIC FAN BLADE TO PENETRATE THE RADIATOIR CAUSING THE ENGINE TO OVERHEAT. THIS DASSUMPTION BY THE SERVICE TECHNICANS MAKES NO LOGICAL SENSE AS THE FORCES REQUIRED TO CAUSE SUCH DAMAGE IS NOT LOGICAL. THE FAN BLADE SITS AT LEAST 3-4" BEHIND THE RADIATOR AND WOULD REQUIRE GREAT FORCES TO MOVE IT FORWARD IN THE OPPOSITE DIRECTION TO SUSTAIN SUCH AN INCIDENT, THERE WAS NO APPARENT DAMAGE TO THE PLASTIC BLADE....
