SIMILAR TO NHTSA ID NUMBER:10717816 AND OTHER COMPLAINTS SEEN ONLINE. EXHAUST SYSTEM COMING APART AT THE FLANGE HEAT FROM THE BROKEN EXHAUST HAD MELTED THE BACK BUMPER ALSO, THE HEAT SHIELD SEPARATING THE EXHAUST FROM THE FUEL TANK APPEARS TO NOT COVER THE AREA OF THE COMMON SEPARATION. NISSAN DEALER SAW THIS OCCUR ON MY CAR, DID NOT TAKE ANY RESPONSIBILITY OF THEIR FAULTY FLANGE OR CARBURETOR. IT WAS IN WARRANTY AT THAT TIME AND THEY SHOULD HAVE FIXED IT. VERY DISHONORABLE PRACTICE TO HAVE A FAULTY FLANGE CREATE ISSUES SIGNALING CARBURETOR REPLACEMENT AND CAR BUMPER MELTED AS A RESULT FROM IT. I BELIEVE AN EXTENDED WARRANTY SHOULD TAKE PLACE TO FIX THIS POTENTIAL ROAD OF CUBE CATCHING FIRE HAZARD, ALTHOUGH IT IS ONLY PLASTIC.
