SIB 52 09 20: Seat noise
Seat noise on BMW G07/G11/G12 models (2019–2024); BMW explains the cause and the approved repair.
BMW service bulletin · NHTSA ID 11022107 · Aug 2025 · also written SI B52 09 20, B520920
What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
Various concerns about the third row of seats (3SR): 1. Head restraint (aka headrest), on one or both sides, cannot be folded down. 2. Third-row seating, on one or both sides, cannot be folded down. 3. Noise from third-row seat backrest when the vehicle goes over bumps.
