BWM refuses to acknowledge that their rims are defective and crack as a result of normal driving, especially their 18 inch rims when coupled with run-flat tires. We don't take speed bumps at 40 mph, run over curbs, or not slow for a potholes... events that might possibly crack a rim or break a tire. Yet BMWs excuse for not replacing 2 cracked rims was that the cracks must have been caused by the driver, not faulty rims/run-flat tire combination. In the past several years we have owned 3 BMWs... but this will be our last because of such a head-in-the-sand approach taken by BMW NA.
Admit to the obvious problem of a faulty combination of 18-inch alloy rims with very hard run-flat tires and issue a recall instead of rejecting request for warranty claims by dealers on behalf of owners.
