Flagship on Rockville Pike, near Target. I have used this car wash forever but have never taken my Model Y to an automated car wash. I would only be comfortable recommending that you use the self-service wash bays with your Tesla vehicle.
I read stories about automated car washes and Tesla not being a good match. I am not sure how much I believe the stories but I also hate washing cars as it was family time while my friends went off to have fun when I was a kid.
This led me to Mobile One Services. They come to my house and hand wash my car once a week. Very reliable. Highly recommended.
