The positive battery cable completely sheared off preventing the car from starting. The circular lug used to connect the cable to the positive battery post is too thin for the size of the cable and extra safety fuses and circuitry. To make matters worse such a poorly designed part has a lead time from Ford's oem in mexico of 4-6 weeks. The car has been at north central Ford in richardson, texas, since 15 August. After missing the part delivery deadline three times the dealership finally provided a rental car. As of the writing of this issue the Ford Fiesta has been in the shop for 26 days, still waiting for the original part from the oem.
