I received this message a few weeks ago while driving from Charleston SC to Atlanta. The car seems to be driving fine but as a precaution I set up a service appointment. I received a message today that the cost to repair the car would be over $1200. It's a 2020 Model S with ~12000 miles on it; I've had this car 20 months and would think this would be covered under the warranty. Has anyone else experienced this?
