Found this googling around for my experience. I created an account as I have been experiencing VERY SIMILAR symptoms on a 2026 Tesla Model Y. I'm actually going to sell it at a loss after only two months. Inner ear pain in both ears, congestion and sometimes throat discomfort. NEVER had this issue in any other car or in my other gas car. 100% happens inside the car and the symptoms linger.
I would love to have a chat with you about your symptoms. Maybe message me and we can schedule a phone conversation.
