I live in Regina Sask.(for those who don't know, this is in Canada). Anyways, we just got our first week of -40 to -45 degree weather.
My CEL came on(I have a 2007 RX 8 with under 1000clicks). It has been sitting in the garage for 3 days. I booked an appointment at the dealership, but today the light went off so I canceled. But tonight I went out again(still -36 degrees outside)... and the light came on again. Everything still runs great. Should I be concerned??

Sorry guys for the long winded story.
