The CX-5 Diesel has a Selective Catalytic Reduction (SCR) system. There is an SCR/AWD harness that has a unique routing around the SCR tank cover. Over time, contamination (i.e. sand, dirt) on the SCR/AWD harness may cause wear on the harness wiring and insulation due to vibrations of the SCR tank cover. In the worst-case scenario, the electrical circuits in the wiring harness can be disconnected with the MIL/SCR/4WD resulting in the warning lights do not work properly.
The Mazda CX-5 vehicles affected by this recall were manufactured between 15 May 2018 and 24 September 2020.
