Symptoms

Owners of certain 2021 BMW X3 and X4 vehicles may notice a distinct groaning noise. This sound typically originates from the area of the shoulder safety belt support. The noise is most commonly heard when the vehicle is accelerating or cornering. It can affect both the driver's seat and the front passenger seat. If you experience a 2021 BMW X3 groaning noise under these conditions, your vehicle may be subject to this issue.

Diagnosis / Trigger Conditions

The groaning noise is specifically linked to vehicle dynamics, appearing during acceleration and cornering. This suggests that the movement and stress on the shoulder safety belt support during these maneuvers are the primary triggers. The issue can manifest in either the driver's or the front passenger's shoulder safety belt support, indicating a potential design or material characteristic rather than a single isolated failure point.

Repair Procedure Summary

While the specific repair steps are not detailed in the provided summary, manufacturer communications like this typically involve an inspection of the affected shoulder safety belt support. Technicians would likely assess the mechanism for any friction points, wear, or misalignment. Potential remedies could include lubrication of moving parts, adjustment of the support mechanism, or, if necessary, replacement of the shoulder safety belt support assembly. The aim is to eliminate the friction causing the 2021 BMW X3 groaning noise.

Owner Action

If your 2021 BMW X3 or X4 is exhibiting a groaning noise from the shoulder safety belt support during acceleration or cornering, it is recommended to contact your authorized BMW dealer. Inform them about the specific symptoms you are experiencing. Referencing manufacturer communication NHTSA ID 10214262 may help the service department quickly identify the issue.
