2001 Infiniti G20

SULPHER SMELL INSIDE CAR: THE DEALER TRIED TO FIX THE PROBLEM BUT COULD NOT. EVENTUALLY THE SMELL WENT AWAY BY ITSELF, OR WHAT EVER SMELLED LIKE SULPHUR WHILE IT WAS BURNING FINALLY BURNT UP.*AK HERE IS A LIST OF OTHER REPAIRS THE DEALER HAS MADE: NEW ALTINATOR NEW WEATHER STRIPING ON DRIVER SIDE DOOR-NOW ITS COMING OFF AGAIN NEW REGULATOR FOR WINDOW ON DRIVER SIDE DOOR NEW MOTOR MOUNTS NEW LINKAGE UNDER FOR THE TRANSMISSION- COULDN'T REMOVE KEY FROM IGNITION UNLESS THE GEAR SHIFTER WAS BEING PUSHED FORWARD AT THE SAME TIME. NEW POCKET FOR THE BACK OF THE PASSENGER SEAT ENGINE NOISE OR RATTLE- INSTALLED BOLTS SOMEWHERE AROUND THE EXHAUST MANIFOLD. THE DEALER SAID THAT THE MANUFACTUR RAN OUT OF THOSE BOLTS DURING ASSEMBLY, AND THINKING THEY WERE NOT NESSISARY, SOLD MY CAR AS WELL AS OTHERS WITHOUT THOSE BOLTS. REPLACED THE BOLTS FOR THE HEAT SHIELD OR THE EXHAUST MANIFOLD. AFTER MORE THAN SIX TRIPS BACK TO THE DEALERSHIP THEY PUT A NEW AC COMPRESSOR ON THAT QUIETED THE NOISE FOR A FEW DAYS, BUT THE NOISE IS BACK. I HAVE SINCE QUIT DRIVING THIS CAR UNTIL I FIGURE OUT WHAT TO DO. THE INCIDENT DATE IS NOT ACCURATE BECAUSE I DON'T HAVE ANY OF THE REPAIR ORDERS INFRONT OF ME.
