"We were informed by our ownership team that there is an issue with some rust spots on the metal plate-side markers on your Model S. I have reached out to our engineers on your behalf and was informed of an upgraded part to counter this issue. We have new side markers available with a Nickel plate instead of the Steel plates currently on your Model S.
These parts have been ordered and as soon as they arrive, we will reach out to you to book an appointment and have them replaced. If this issue has been mentioned previously to someone on our team, I apologize for it not yet being addressed."
