Pretty sure this massive effort is to avoid that, they won't return it until it's fixed because if it breaks for the same reason I think it's eligible.
You should check your state lemon laws as there may be several qualifying criteria including the number of days its been out of service. Passing a certain numbers of repairs for the same problem can also qualify. In California, more 4 failed attempts to repair the same problem or more than 30 days out of service qualifies a car to be repurchased or replaced by the manufacturer.
