2002 MITSUBISHI DIAMANTE Structure Problems

NOTICED FAINT SMELL OF ANTI FREEZE APPROXIMATELY 9 MONTHS AGO. HAD PROBLEMS WITH DEFROSTER CLEARING WINDOWS. ALSO, SEEMED TO GET BETTER (OR MAYBE I GOT USED TO THE SMELL). NOW NOTICED PASSENGER SIDE FLOOR CARPET IS SOAKED WITH ANTI FREEZE. OBVIOUSLY A PROBLEM WITH THE HEATER CORE OR THE HOSE(S) WHICH CONNECT TO IT ARE LEAKING. CAR HAS 92000 MILES, AND IS WELL MAIN. *TR

I HAVE A 2002 MITSUBISHI DIAMANTE. I HAVE KEPT REGULAR MAINTENANCE. I AM SUBMITTING THIS FORM BECAUSE OF A HEATER CORE ISSUE I AM HAVING. HOWEVER I HAVE HAD THE FOLLOWING PROBLEMS WITH THIS CAR. ALL THESE PROBLEMS SEEM TO BE RECURRING PROBLEMS THAT HAPPEN TO MANY PEOPLE WITH THIS MODEL. AT LEAST THAT IS WHAT I FIND WHEN I SEARCH THE ISSUES ON THE INTERNET 1- VIBRATION IN STEERING WHEEL --THIS HAPPENED MULTIPLE TIMES AFTER TAKING CAR BACK TO DEALER-IT APPEARS THERE IS A KNOWN ISSUE WITH THE ROTORS IN THIS CAR. AFTER HAVING THE ROTORS CUT TWICE BY THE DEALER WITH NO LONG LASTING SUCCESS. I HAD TO HAVE THE BRAKES AND ROTORS REPLACED BY A MECHANIC ( CAR HAD LESS THE 10,000 MILES WHEN ISSUE STARTED HAPPENING) 2- RUSTED MUFFLER--NOT SURE IF THIS ISSUE HAPPENS OFTEN BUT AFTER 23,000 MILES I HAD TO HAVE MY MUFFLER REPLACED...
