NHTSA Complaint #10782170 — 2011 BMW Z4

I'M A OWNER OF 2011 BMW Z4 35I WITH 296 STYLE WHEELS. BMW'S 296 STYLE WHEEL CONSIDERED HAS DESIGN DEFECTS BY MOST OF OWNERS, SINCE THEY REALLY EASILY CRACKED WITHOUT IMPACT. REASON WHY 296 STYLE WHEELS GOT EASILY CRACKED DEFINITELY SEEMS FLAWED DESIGN, AND IT CAN BE PROVED BY OTHER WHEELS WITH SAME DIAMETER DON'T HAVE THESE KIND OF PROBLEM. ALSO FATIGUE STRUCTURE FAILURE MEANS, STRUCTURE STRENGTH OF WHEEL DESIGN WASN'T PROPERLY REVIEWED. ALSO BMW CHANGED ITS DESIGN OF INNER BARREL TO REINFORCE STRENGTH AROUND 2012. THERE WAS SETTLEMENT BETWEEN OWNERS AND BMW NA ABOUT THIS ISSUE, BUT IT ONLY COVERS DURING INITIAL FACTORY WARRANTY. (HTTP://Z4296WHEELSETTLEMENT.COM) ALTHOUGH MY BMW Z4 DOESN'T HAVE INITIAL FACTORY WARRANTY, IT STILL HAS CPO WARRANTY. BMW NA AND LOCAL DEALER REFUSED TO REPLACE OR FIX MY CRACKED WHEELS, SINCE MY CPO WARRANTY DON'T COVER WHEELS. THE REASON CPO WARRANTY DOESN'T COVER WHEELS SEEMS THEY CAN BE DAMAGED FROM CURB OR POT-HOLE. (NEITHER OF THEM ARE MY CASE.) HOWEVER IF MOST OF OWNER SUFFERED BY SAME PROBLEM, IT DEFINITELY CAN BE CONSIDERED TO CAUSED BY FLAWED DESIGN, NOT MIS-USE OR ABUSE BY OWNER. IN ADDITION, BMW SHOULD REPLACE THOSE WHEELS REGARDLESS WARRANTY PERIOD. (THIS IS WHAT HAPPENED IN S.KOREA. BMW KOREA ADMITTED ITS PROBLEM AND CHANGING OWNERS 296 WHEELS REGARDLESS THEIR WARRANTY PERIOD.) PLEASE FIND RELEVANT LINKS AS FOLLOWS.
