2011 CADILLAC CTS Wheels Problems

I WAS TRAVELING SOUTH ON RT 10 PROVIDENCE RHODE ISLAND WHEN I HIT A POT HOLE, THAT SPLIT THE WHEELS DIAMETRICALLY, AND DEFLATING THE TIRES. THE WHEELS ARE MANUFACTURED BY TSW, JARAMA, 20 X8.5 5X120 ET35, AND 20 X10 5 X120 ET35 RESPECTIVELY. WHEN THE WHEELS SPLIT, I LOST CONTROL OF THE CAR, BUT MANAGED TO GET THE CAR OVER TO THE SIDE OF THE HIGHWAY. I CALLED THE RI STATE POLICE AND FILED AN INCIDENT REPORT. MY CONCERN IS THE WHEELS SPIT SIMILARLY EVEN THOUGH THEY ARE OF DIFFERENT SIZES, DIFFERENT BATCHES, AND SPLIT THE SAME. THIS RESULTED IN A VERY DANGEROUS SITUATION, AND I THOUGHT WOULD BE IMPORTANT TO REPORT THE INCIDENT. I DID CONTACT THE MANUFACTURER, AND THEY SAID I MUST OF HIT SOMETHING SIGNIFICANT TO CAUSE TWO WHEELS TO BREAK. MY PERSPECTIVE IS THEY FAILED IDENTICALLY WHICH SUGGESTS A DESIGN ISSUE, AND A NOT A PRODUCT...

WHEN BACKING OUT OF DRIVEWAY AND TURNING THE STEERING WHEEL TO THE RIGHT WE NOTICED A PRONOUNCED THUMP THAT WAS VERY NOTICEABLE AND WORRISOME. WE CHECKED WITH THE DEALER AND COULDN'T FIND THE PROBLEM AND THE DEALER CHECKED WITH GENERAL MOTORS WHO SAID IT WAS A DESIGN FLAW AND COULDN'T DO ANYTHING ABOUT IT. IT HAS BEEN DOING THE SAME THING UP TO THIS DATE. THE THUMP IS SO GREAT WE WONDER IF IT IS NOT DAMAGING THE CAR. *TR

MY HUSBAND WAS DRIVING IN OUR COMMUNITY, ABOUT 15 MPH. HE MADE A RIGHT HAND TURN AND THE CONTROL ARM SNAPPED IN HALF, THE WHEEL BROKE OFF AND THE FRAME CAME CRASHING TO THE GROUND. WE HAVE OWNED THE CAR FOR LESS THAN 3 WEEKS. AAA TOWED THE CAR TO THE NEAREST DEALERSHIP. THE DEALERSHIP REFUSES TO FIX THE CAR UNDER THE MANUFACTURER'S WARRANTY CLAIMING THAT THE CAR HAD TO HAVE BEEN IN AN ACCIDENT. WE HAVE NEIGHBORS WHO HEARD THE THUD AND CAME TO SEE WHAT HAPPENED. THERE WAS NO ACCIDENT/COLLISION. WE HAVE DRIVEN THE CAR A COUPLE HUNDRED MILES. THIS SHOULDN'T HAVE HAPPENED. CADILLAC TOLD US WE NEEDED TO FILE A CLAIM WITH OUR INSURANCE COMPANY. THE DEALERSHIP ESTIMATES $12,000 IN DAMAGE. *TR
