We had a bad rain last night and I drove through some thick mud and gravel near my house. My wheels and wells were caked this morning so I drove slowly to a nearby car wash and sprayed the mud off with the washer. For a few miles I could hear the remaining rocks and mud come out of places it must have been stuck. It sounded like a rubbing sound for a few miles then it quit. Now there is a high pitched squeaking noise at low speeds and when turning the wheel from the front driver's wheel. Tesla service didn't seem too concerned and it has been slowly fading as i drive. I'm going to let it dry in the sun fit a few hours and try driving again. Can a rock or gravel get lodged anywhere under there to do damage and has anyone else heard squeaking after washing their wheels and wells? It's not the brakes since I hear it during acceleration also.
