It sounds to me like US Bank is in the driver's seat and wants to make arbitrary rules. I doubt that you would find anything that could force them to change their position (something in the contract, or a law).
I believe that most (if not all) of the lessees have found that the banks prefer to send the Volts to auction if they can't get the residual price shown on the contract. My salesman had told me that they were insured against the loss; that is, the price gotten at auction verses the residual price shown on the contract was reimbursed to them through insurance. I don't know if that is true - or possible, but there it is.
