2003 Chrysler Sebring Convertible

I HAVE A 2003 CHRYSLER SEBRING CONVERTIBLE THAT HAS CHROME/ALUMINUM WHEELS. I NOTICED THAT I WAS LOSING SUBSTANTIAL PRESSURE IN MY TIRES ON A REGULAR BASIS. THINKING THIS WAS A PROBLEM WITH THE TIRES, AND THE CAR WAS UNDER WARRANTY, I TOOK THE CAR BACK TO THE CHRYSLER SERVICE CENTER IN WYCKOFF NJ WHERE I PURCHASED IT. UPON INSPECTION, THE SERVICE TECHNICIAN INDICATED THAT THERE WAS NOTHING WRONG WITH THE WHEELS AND THAT I SHOULD MAKE SURE TO KEEP THE TIRES PROPERLY INFLATED. THE PROBLEM PERSISTED AND, WHEN I BROUGHT THE CAR TO MY REGULAR (NON-CHRYSLER) MECHANIC, HE POINTED OUT THAT MY RIMS WERE CORRODING FROM THE INSIDE AND THAT THIS AFFECTED THE BEAD ON THE TIRE AND CAUSED IT TO LOSE PRESSURE. HE INDICATED THAT HE HAD CALLED CHRYSLER AND BEEN TOLD THE PROBLEM WAS NOT COVERED UNDER WARRANTY. I HAVE SINCE READ THAT THIS IS A COMMON PROBLEM WITH SEBRING RIMS. I SENT AN INTERNET COMPLAINT TO CHRYSLER'S WEBSITE BUT RECEIVED NO RESPONSE. MY MECHANIC ADVISED THAT ALL HE COULD DO, INSTEAD OF TOTAL REPLACEMENT, WAS GRIND DOWN THE OLD RIMS AND TAR OVER THEM AS A STOP GAP SOLUTION. I EXPERIENCE ADDITIONAL LOSS OF PRESSURE ABOUT EVERY OTHER DAY AND HAVE TAKEN THE CAR BACK TO TIRE DEALERS TWICE TO REGRIND THE RIMS. EACH TIME THEY POINT TO THE CORROSION AND THEIR FRUSTRATION WITH CHRYSLER NOT DEALING THE PROBLEM. HAVING TIRES LOSE PRESSURE BECAUSE OF A DEFECT IN THE DESIGN AND PERFORMANCE OF THE WHEEL IS A CLEAR SAFETY HAZARD. I HOPE NHTSA WILL LOOK INTO THIS AND REQUIRE CHRYSLER TO STAND BEHIND ITS PRODUCT. THANK YOU. *TR
