TSB Document:

Affected Component: EQUIPMENT ADAPTIVE/MOBILITY

Summary
Some customers may complain about the following braking concerns when coming to a stop while following a vehicle ahead using Mazda Radar Cruise Control with Stop and Go function (MRCC). Harder braking at slow speeds just before a complete stop. Before coming to a complete stop, the vehicle creeps towards the vehicle ahead and Depress Brake Pedal warning message may appear in the instrument cluster. This is caused by improper control software of the DSC HU/CM. To eliminate this concern, the control software of the DSC HU/CM has been modified.
