2003 OLDSMOBILE SILHOUETTE Wheels Problems

ALL WHEELS ARE CORRODED AND LEAKING AIR AROUND VALVE STEMS. *TR

IN 2005 OR 2006 I TOOK THIS OLDS. IN BECAUSE THE CHROME ON THE INSIDE OF THE WHEELS WAS COMING OFF THE WHEELS.....THEY SAID NOTHING COULD BE DONE ABOUT IT. NOW IN 2008 THE VALVE STEMS ON ALL 4 WHEELS ARE LEAKING BECAUSE OF THE CORROSION OF THE WHEELS. I DON'T FEEL THIS IS SAFE AS MY WIFE HAS TO CHECK THE TIRES AND ADD AIR EVERY COUPLE OF WEEKS. I'VE HAD NEW VALVE STEMS PUT IN, BUT THEY STILL LEAK. I FEEL GM SHOULD REPLACE THE WHEELS AS THIS IS AN UNSAFE CONDITION. I'M SURE THERE HAVE BEEN OTHER COMPLAINTS ABOUT THIS, AS ALL 4 WHEELS ARE DOING IT. *TR

NOTICED DECREASE IN TIRE PRESSURE ON ONE TIRE THEN ON ALL. EXAMINATION OF RIM SHOWED EXTENSIVE CORROSION ON ALL RIMS BOTH EXTERIOR AND INTERIOR. LEAKAGE WAS SO BAD THAT I WAS FILLING THE TIRES DAILY. WENT TO TIRE STORE WHERE I PURCHASED THE TIRES TO HAVE THEM EXAMINED. SERVICE REP SAID IT WASN'T THE TIRES IT WAS THE CORRODED RIMS THAT WERE CAUSING THE PROBLEM. I HAD THE RIMS REPLACED (ALL 4) AND HAVE NOT HAD A PROBLEM SINCE THIS REPAIR. IN CONVERSATION WITH THE STORE REP HE COMMENTED THAT I WASN'T THE FIRST PERSON TO COME IN WITH THIS PROBLEM AND THAT HE HAD SEEM ~10 VEHICLES WITH THIS PROBLEM OVER THE PAST TWO MONTHS. IN FACT< AS SOON AS I BROUGHT THE VEHICLE IN AND EXPLAINED THE PROBLEM IT SEEMED THAT HE KNEW EXACTLY WHAT THE CAUSE WAS. I HAVE KEPT THE RIMS FOR EVALUATION IF ANYONE IS...
