Some vehicles equipped with Smart Brake Support (SBS) may exhibit a front radar system malfunction message in the instrument cluster with DTC C1A67:04 (front radar sensor internal malfunction) stored in memory. This may be caused by water penetrating into the front radar sensor through the breather hole when exposed to a great amount of water and damaging the radar sensor, resulting in the DTC C1A67:04. To eliminate this concern, the front radar sensor has been modified.
