2013 Mazda CX5 roughly 64,700 miles on it. Check engine light came on today, took to Auto-Zone to get error code, as well as local dealership and they said that there was no error code?
The light remains on, vehicle drives as it should, but 2 different places are not seeing an error code. What could be the cause of the light coming on?
EDIT
Let me also add that oil changes etc are performed every 5K miles like clock-work and the next one is scheduled for 66K miles so I am just under 1,500 miles from that. I also checked fluids and everything is at a sufficient level (not low).
