NHTSA Complaint #10583466 — 2004 NISSAN QUEST

MY VAN INDICATED A PROBLEM WITH A MIL ON THE DASH. AFTER GETTING IT TESTED THE CODE INDICATED AN ISSUE WITH A VENT VALVE P0447. I REPLACED THE SUGGESTED PART AND IT DID NOT FIX THE PROBLEM. AFTER RESEARCHING THE ISSUE, I FOCUSED MY ATTENTION ON THE ECM AS IT CONTROLS ALL THE SENSORS IN THE VEHICLE. I REMOVED THE ECM AND NOTICED RUST AND CORROSION RIGHT AWAY. NISSAN DOES NOT CONSIDER IT BE A DEFECT, HOWEVER THE ECM IS MOUNTED UNDER THE LEAF SCREEN WHERE WATER IS SUPPOSED TO DRAIN. UPON REMOVING THE COVER TO THE ECM IT WAS DISCOVERED THAT THE CORROSION FROM THE WATER ATE AWAY AT THE METAL AND CREATED A HOLE IN THE SEALED ECM AND ALLOWED WATER TO GET AND CAUSE DAMAGE TO THE CIRCUIT BOARD. MY PROBLEM WAS ONLY 1 SENSOR, BUT IT WON'T PASS REQUIRED EMISSION IN MY STATE. THERE WERE SOME REPORTS OF DRIVABILITY ISSUES BY OTHERS THAT HAD THE DEALER TELL THEM THEY NEED THE ECM REPLACED AND IT WAS NOT COVERED UNDER WARRANTY. THIS IS A DESIGN FLAW AND SHOULD BE REPLACED BY THE MANUFACTURER. *TR
