Tesla originally refused to repair the headrest under warranty last year when I first noticed the issue. I refuse to pay them $300+ for a headrest that has failed. Well, it's gotten worse and I think my time to wait is getting shorter and shorter. I just scheduled an appointment asking for it to be covered by warranty and they sent an invoice/estimate stating $301. Should I demand they pay for the repair and then what are the other two listed items as I didn't put those? I don't use hair products other than shampoo and it's only the one headrest doing it.
