The rear right wheel fell off while driving at an undetermined speed. This was caused by the lug separating from the nut because it was not long enough at time of manufacturing. An insurance adjuster observed the lug nuts on the vehicle and reported that they were illegal as no threads on the studs came through the nut. She stated that the failure should be covered under warranty and the insurance company couldn't do anything. When the consumer learned of a technical service bulletin concerning a stud change from 12mm to 14mm two months after the consumer's vehicle was manufactured. The insurance company did pay for the work to repair the vehicle.
My spare tire fell out from beneath my truck. The cable was split at the end. The small connector that is attached to the cable had separated from the end of the cable which also holds a metal pad in place. The pad allows the spare tire to be raised or lowered. All parts were retrieved, the spare tire, metal pad and connector. The spare tire hoist assembly was still operational, minus the parts that fell out.
