Ever since i got my 550 (2023,7k-mile used, no accident) this February, I noticed the driver side door squeaks when I opened the door. I felt like it's been getting worse. And searching from all similar posts around the forum, mine sounds the worst.
Here is the video
I surely dont wanna go insane but as you can see&hear it squeaks everytime i opened the door, there's no escape.
It seems to me that it's not from the door hinge but from inside the door panel, somewhere under the mirror.
I will try my luck with dealership but im not sure if they can resolve it the first try. Would love to hear if anyone encountered this issue before.
Thanks!
