2022 Mercedes GLS450 Seat Noise

The 2022 Mercedes GLS450 is a very luxurious and comfortable 7-seat SUV. Everything inside is elegantly designed with high quality. This SUV is equipped with massage seats and they are super comfortable massaging your back for long trips. Driving 8 hrs is like flying first class on a 8-hr flight without feeling cramp to the back and legs.
There is a minor defect for my GLS where the passenger seat fan was making noise. The dealer was quick to respond and got it fixed within 2 weeks.

I really appreciate this video. Are you able to elaborate on what the fix was?
