NHTSA Complaint #11511753 — 2023 VOLVO XC90

1)Rear 2nd row seat Creaking noises. I visited the dealer 3 times, showed evidence with video clips what I recorded, but they couldn't find the cause. I thought that replacing the entire seat was the best way, but the work was finished by applying lubricant only, and this phenomenon continues even after that. The noise disappears when the seat is folded and unfolded as a trial, but it reappears after a few days, and there is no noise when the passenger sits in the seats. These cases are mentioned in swedespeed.com, a user's Internet forum, but there seems to be no improvement. The problem is noise that interferes with the concentration of driving. 2) When passengers board the 2nd and 3rd row seats and do not wear belts, there should be a warning sound and warning message, but there is none. 1st row seat works fine.
