What owners report
During a trip driving from Sedona to San Diego, the rear passenger side rim (Part No. 25740120007x23) (see Picture1) failed with a through crack on the shoulder opposite the spoke side (see Picture2). This led to the loss of air pressure in the tire. The tire pressure sensor did indicate a low pressure condition. Upon inspection of the rim, the only possible solution was to have it welded in order to continue the trip. When the rim was taken to the repair shop, three more cracks were discovered on the rim inner surface. None of these three cracks have not gone through the rim wall yet. All crack were on the shoulder opposite the spoke side which cantilevers towards the center of the car. Wel
