Last week, took my car to the dealer, after I made another recording demonstrating the noise. Went for a drive with the tech, just around the lot and immediate area. He heard the noise. They kept the car and called me the next day. It needs a new front right strut. Actually there was a lot more discussed at the time, but that is a whole other matter.
Picked up my car yesterday from dealer, after they had it for 5 days. I did not hear any noise. When I look through the Maintenance paperwork, it clearly indicates that they checked for loose body and suspension parts, but found none. Then drove the car with "Chassis Ears", and were able to isolate to the front right strut.
I must say the dealer was good to work with through this project. In particular the Service Manager. He called me directly last week for us to discuss the issue.
Hoping this is solved, and will report back if anything changes.
