Less than 2,000 mi and "service engine soon" light comes on on 2010 Nissan Versa

My 2010 Nissan Versa is less than 5 months old and has less than 2,000 miles on it. Tonight the "Service Engine Soon" light suddenly came on, apparently for no reason. I live in Memphis and the temp was 98 degrees today (it's not even summer yet --ugh) but the light didn't come on until around 9:00 pm. I lost my job 3 days after buying the car and can't afford any repairs, especially for a car I just bought. Does anyone have any ideas? Your help would be very much appreciated!
