I had kind of the same issue. When I took it in to the dealer, they said the SC was jacked up. The rotors inside were hitting or something. They just put a new one on there, and it went away

I have the same problem ever since the fist oil change. I checked the oil, and it was fine. I took it back to the dealers and they told me that was normal. Not normal to me but it’s been 2 1/2 years with no problems.
