NHTSA Complaint #11161140 — 2016 CHEVROLET CORVETTE

FOUR REAR WHEELS HAVE CRACKED LEAKING AIR AND HAVE NO EXTERNAL DAMAGE FROM ROAD HAZARDS. TWO WERE REPLACED UNDER THE NEW CAR WARRANTY AND TWO WERE REPLACED UNDER GM'S PURCHASED EXTENDED WARRANTY. THE FIRST ONE, RIGHT REAR, CRACKED ON 11/19/16 WITH 18,843 MILES ON THE CAR. THE SECOND ONE,LEFT REAR, CRACKED ON 8/23/17 WITH 24,332 MILES ON THE CAR. THE THIRD ONE,LEFT REAR, CRACKED ON 8/14/18 WITH 34,854 MILES ON THE CAR. THE FOURTH ONE, RIGHT REAR, CRACKED ON 10/17/18 WITH 39,501 MILES ON THE CAR. CALLING THE GM HOT LINE I WAS TOLD TO CONTACT MY GM SERVICE DEPARTMENT IN REGARDS TO THIS ISSUE. THEY TOLD ME THE THE WHEEL WAS DESIGNED TO CRACK TO PROTECT THE REAR SUSPENSION !!! THIS IS A HUGE SAFETY ISSUE. WHAT WOULD HAPPEN IF THAT CRACK LEAD TO A WHEEL FAILURE AT SPEED? I HAVE ALL MY GM SERVICE STATEMENTS TO BACK THESE FACTS UP. GM NEEDS TO CORRECT THE PROBLEM!
