2021 BMW X5 xDrive40i, about 61,500 miles. A windshield was replaced and now there is a whistle around highway speed that did not exist before.
2020 Mercedes-Benz E-Class E450, about 56,500 miles. The light was on for two days and then disappeared before I could schedule service.
There is a light buzz from the dash at one narrow RPM range. It disappears above and below that speed.
