It a new model and dealers are clueless. So sadly this kind of thing might take awhile to sort out. I would log all lost time (IE: time vehicle was not driveable) and make sure to document everything they tell you, get names and dates, be very specific because as time passes everyone's memory will fade on exactally what was said and done, ask for things in writing if possible. Assume your going to trial, collect evidence. Hope this gets sorted out quickly and to your satisfaction.
