1994 NISSAN QUEST Engine And Engine Coolingexhaust System Problems

THE FRONT AND REAR EXHAUST MANIFOLD SYSTEM BROKE. DEALER NOTIFIED. *NLM

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

EXHAUST MANIFOLD BOLTS BROKE AND STUDS REMAINED IN MANIFOLD. EXHAUST LEAKED IN ENGINE BAY. WAS TOLD BY NISSAN DEALER THAT POSSIBLE AFFIXIATION COULD RESULT FROM RUNNING THE AC AND THE EXHAUST LEAK CREATED BY THE BROKEN BOLTS. THERE WAS A QUEST THERE WITH THE SAME PROBLEM. HAD QUEST FIXED ELSEWHERE. WHEN DOING OIL CHANGE A MONTH LATER, ANOTHER QUEST WITH SAME PROBLEM. WAS TOLD BY NISSAN MECHANIC AND MY MECHANIC THAT THIS IS EXTREMELY COMMON IN THE VAN. THERE SHOULD BE A RECALL DONE ON THE EXHAUST LEAK. ACCORDING TO THE NISSAN DEALER, THE EMMISIONS COULD BE NON ODOROUS AND MAY NOT BE DETECTED BY SMELL. I FEEL THIS IS EQUALLY OR EVEN MORE DANGEROUS THENA THE FUEL VENT PROBLEM BECAUSE THIS IS INVISIBLE. AT LEAST YOU COULD SMELL THE GAS LEAK AND SEE THE GAS ON THE GROUND.*AK

THE EXHAUST MANIFOLDS STUBS BROKE OFF INSIDE THE ENGINE ALLOWING THE EXHAUST MANIFOLDS TO SEPARATE FROM THE ENGINE BLOCK, THIS ALLOWS EXHAUST GAS TO ESCAPE FROM THE CRACK BETWEEN THE MANIFOLD AND ENGINE BLOCK THUS CAUSING A PUTTERING NOISE IN THE ENGINE COMPARTMENT, NISSAN IS AWARE OF THE PROBLEM, TSB 94041 WAS ISSUED APR 94. NLM

EXHAUST SYSTEM HAS FALLEN OFF A TOTAL OF 4 TIMES; 3 TIMES UNDER WARRANTY, AND 1 TIME CONSUMER HAD TO PAY FOR REPAIRS. DEALER COULDN'T TELL WHY. A MECHANIC TOLD CONSUMER THEAT PEGS ARE MADE OF BRASS, AND WHEN MOTOR GETS HOT IT EXPANDS. ALSO, INSIDE OF VEHICLE SMELL LED LIKE ROTTEN EGGS. *AK

FUEL VAPORS INSIDE CAR. TEMPERATURE NOT A FACTOR. EXCESSIVE AFTER FILL-UP BUT VAPORS CONTINUE SEVERAL DAYS AFTER FILL-UP. BRAKE NOISE ON LEFT SIDE-CHIRPING. WAS TOLD BRAKE ROTOR WARPED-ORIGINAL EQUIPMENT. *AK

NO SUMMARY LISTED FOR ABOV EVEHICLE. *AK

BOLTS THAT HOLD EXHAUST HEADERS TO THE BLOCK BREAK, AND EXHAUST FUMES ENTER THE PASSENGER'S COMPARTMENT. APPARENTLY A COMMON PROBLEM AND EXCESSIVLY EXPENSIVE TO REPAIR AND ? WHETHER THE SAME PROBLEM WILL RE OCCUR. *AK

STUDS BROKE ON LEFT MANIFOLD WHICH RESULTED IN WARPED MANIFOLD SYSTEM. THIS OCCURRED UNDER NORMAL VEHICLE USE. IF NOT REPAIRED THIS DEFECT COULD PRESENT A PROBLEM OF POTENTIAL EXAUST FUMES IN DRIVER/PASSENGER COMPARTMENT AND/OR BREAKAGE OF MANIFOLD COMPONENTS DROPPING IN ENGINE WHILE TRAVELING.
