I've only had my Spark EV for a week. While driving home on the freeway yesterday the service light came on and stayed on for the ten minutes it took me to arrive home. (Had to get out the manual to see what it meant; looks to be similar to a "check engine" light on a gasmobile). Air temp was about 80 degrees and the air conditioner had been running the full time, so it may have something to do with what's mentioned in the posts above. Called the dealer and made an appointment to take the car in this coming Wednesday.
Drove the Spark about ten miles today with the A/C running to see if the light came on again. It didn't. I plan to continue making short trips in the car for the next couple of days unless the light comes on again. If it does I'll park it until the Wednesday appointment. If it doesn't, I'll cancel the appointment. Few things are more frustrating than an intermittent problem that won't show itself to a dealer's service adviser.
You should be able to contact OnStar when the CEL (Check Engine Light) is on and ask them for any codes associated with the CEL. Even if it goes out again, the dealer should be able to pull the codes if they were serious enough to be stored. I'd want to get to the bottom of whatever it is, and so should GM. Take it in if you can, unless OnStar says it's nothing to worry about. If the dealer has to keep it, you should insist on a loaner, another Spark EV, or a Volt, would be my choice, since you won't need to put gas in either of those...
