Some customers may complain about a shift shock and/or an engine RPM increase when setting the Mazda Radar Cruise Control (MRCC) system with no DTCs being stored. NOTE: This concern only occurs on vehicles equipped with a PCM manufactured by MITSUBISHI.This is caused by improper control logic of the PCM allowing the engine RPM increase for an instant right after setting the MRCC. To correct this issue, the PCM software has been modified.
