Start documenting it for lemon law buy back, you're almost there. If they are unable to fix it in four visits or if they have the car over 30 days. I had a nightmare on a Town & Country that intermittently wouldn't start and kept stranding my wife and kids one winter. My advice.... Go to a different dealer. I kept going to the same dealer thinking it would help because they had all the history, and that was my biggest mistake. It's warranty work regardless of the dealership. If you want to keep the car take it somewhere else, if you want to cut your loss and get rid of the car then take it back to the same dealer because they likely won't fix it this time either.
There may be some kind of consumer purchase laws that could help you since you purchased it 11 days ago, but I don't know much about that.
PM me if you want a number of a good lemon law attorney, they will all gladly talk to you and let you know your options.
