Nissan Murano front radar intermittently stops working, affecting I-FCW and emergency braking on Nissan Murano

Some Nissan Murano owners report experiencing issues with the front radar intermittently stopping working, which can affect critical safety features like Intelligent Forward Collision Warning (I-FCW) and emergency braking. These problems are often indicated by a dashboard warning message stating "Front radar unavailable due to obstruction," suggesting that the radar sensor may be blocked or malfunctioning, thereby disabling automatic braking. Causes of this issue can include debris, snow, faulty parts, thick paint, or interference obstructing the sensor's functionality. It is advisable for owners encountering this problem to address it promptly to ensure the proper operation of essential safety systems. Dealerships have established procedures to diagnose and resolve these issues, which may involve inspecting, cleaning, or replacing the radar sensor as needed.
