I had two cases where I had to bring legal action against a dealer to get results and there should have been no reason for such action.
On the first, I took a new car, about a week old, back to the dealer to get something adjusted. Some mechanic laid something on a white vinyl top. They tried to clean it and just created a stain. They said they could stain it back white, but that isn't what I bought. I had to have an attorney write a letter to get them to replace it.
I took another new car, maybe 3 months old, in to get timing adjusted. The dealer told me that was a common problem with that model. I told them that was not what I bought and I wanted another model. They said no way but they would give me an excellent trade in on another model. It took an attorney to get them to give me another model with no cost to me other than the difference in base, not sticker, price.
Money I do not have. In my family I do have two attorneys, uncles, a county judge, nephew, a county sheriff, nephew, a forensic criminologist, daughter, and a commander in military investigative services(whatever that is, keep changing names) nephew.
When you bend over backward, give them ever chance in the world, and they tell you they "don't have to," or "aren't going to," you may need to get their attention and splain things to them. Then when you come in, they may treat you a little better.
