2022-2023 BMW iX Radome Heating Failure TSB

BMW has issued a manufacturer communication (NHTSA ID: 10238076) regarding a potential issue with the front ornamental grille and its radome heating system in certain 2022-2023 BMW iX vehicles. The radome heating is crucial for melting snow and ice deposits, ensuring that the sensors located behind the grille function correctly, especially in cold weather conditions.

This 2023 BMW iX manufacturer_communication highlights a manufacturing defect that can lead to interrupted heater circuits and, consequently, a failure of the radome heating system.

Symptoms of Radome Heating Failure

Owners of affected 2022-2023 BMW iX models might notice that the front sensors, which are vital for various driver assistance systems, do not perform optimally in snowy or icy conditions. This is because the radome heating, designed to keep these sensors clear, is not functioning as intended. While specific warning messages are not detailed in the communication, impaired sensor performance in cold weather is the primary indicator of this issue.

Diagnosis of the Issue

The root cause of the problem is a manufacturing defect within the component itself. This defect leads to an interruption in the heater circuits responsible for the radome heating. When these circuits are compromised, the heating element cannot effectively melt snow or ice, leaving the sensors vulnerable to obstruction.

Repair Procedure Summary

To address the radome heating failure, the manufacturer communication indicates that the issue stems from a defective component. While specific repair steps are not outlined in detail, the resolution typically involves replacing the faulty front ornamental grille assembly that contains the defective radome heating elements. This ensures that the new component has fully functional heater circuits, restoring the intended operation of the radome heating and the reliability of the front sensors.

Owner Action

If you own a 2022 or 2023 BMW iX and suspect your vehicle's radome heating may be compromised, especially if you experience issues with front sensors in cold weather, it is recommended to contact your authorized BMW dealership. They can inspect your vehicle and perform any necessary repairs under this manufacturer communication. This ensures your vehicle's safety systems operate as designed.
