Apparently made it mad...
I've never seen a CEL/SES light on a car with less than 5,000 miles and probably the first check engine light I've had on a Nissan since my 1986 P/U after it was over 10 years old with 140k+ miles.
Edit to say that I checked the gas cap...we'll see if that does anything. Will probably get the code read somewhere if it hangs around.
