Hello, I recently purchased a CPO 2020 GLE 350 4matic and have noticed a chirping type sound coming from the right rear roof where the handlebar meets the panoramic roof.

The local mercedes dealer is unable to remove the chirp and has tried fixing it 5 times now including replacing rear grab handle, replacing a few trim pieces as well as tried adding foam near that area. Still the noise is persistent. It is very annoying and I am considering selling the car, but wanted to see if we could give it one last try before I pull the plug.

the car has been at the service center for 4months out of the 9 that I have owned . I am hoping someone can help. Really appreciate your time.

Here are my videos that capture the noise here -
