Hi all, I’m hoping someone here has some experience with this. I have a 2015 Model S 70D and am suffering from some quite loud low frequency road noise coming from the rear of the car. On smooth roads it’s tolerable but on roads with cracks or bumps it’s so loud that my hearing has suffered to the point where I need to wear ear plugs. Is/has anyone else dealt with this issue? An internet search turns up one locked tesla thread where no solution was posted other than contact customer service.
