Forward collision avoidance: adaptive cruise control

Summary

Some vehicles may experience the vehicle speed decreasing unintentionally while using MAZDA Radar Cruise Control (MRCC). This may occur when a vehicle in the adjacent lane is misidentified as being in its own lane, and the MRCC controls decelerate accordingly. This concern is caused by improper control software of the Vehicle Control Module (VCM). To eliminate this concern, the VCM control software has been modified.

Owners of these vehicles have filed 16 complaints in the driver assistance category.
