I leased a 2018 bmw X3 without the factory installed hitch and it was written into, by way of a written "we owe you" tag, and price of the hitch included in the lease contract. My BMW salesman looked into the price and installation of the hitch pricing through available BMW pricing to arrive at the cost. Now after a month I make an appointment with service and they take the car and then say BMW NA is not letting them have hitches for dealer installation, even though they show available for order. So my question now is what should I do? I hate to contact a layer to review this but I'm paying for the dealer installed hitch in my monthly payment yet they cannot get one to install. My salesman emailed someone a few weeks ago at BMW concerning this but I've yet to hear from him.
