2022-2024 BMW iX Tailgate Rattling Noise TSB

Symptoms

Owners of 2022-2024 BMW iX Sports Activity Vehicles may notice a distinct rattling noise emanating from the tailgate area. This BMW iX tailgate rattling noise typically occurs when driving over rough or uneven road surfaces.

Cause

According to BMW Technical Service Bulletin SIB 61 15 24, the root cause of the BMW iX tailgate rattling noise is often a rear washer fluid hose that is not securely fitted. This allows the hose to vibrate and create the noise.
