I will be going on my 4th service visit for this particular problem. There's no communication between the technicians and mechanics at my service center. The invoice stated that they could not replicate the noise so they didn't bother, but the tech said they knew what the problem was and how to fix it. On my 3rd visit, they assured me it would be taken care of, but immediately taking it out of park on pickup day, it sounded exactly like it did when I Brough it in. I'm considering taking it to a third party shop and have it done manually with them.
