SSPA1	2017-09-14. Service bulletin. Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) on certain 2014 Mazda6 vehicles produced from November 8, 2012 through September 27, 2013. On certain 2014 Mazda6 vehicles, a concern has been identified with the software of the vehicle control module (VCM), which controls the Smart Brake Support (SBS) and Mazda Radar Cruise Control (MRCC) features. When the vehicle is driven without stopping for a long time, it is possible that a zero-point of the radar sensor may be inappropriately aligned. Under this condition, the warning light will illuminate and the SBS and MRCC features will stop operating. Dealers are to reprogram the VCM with modified software. The repair must be performed at no charge to the vehicle owner.
