I picked up my Ascent last week and this morning the Check Engine light came on (along with all the other lights on the dash, kinda freaky). I went ahead and drove to work because the lights weren't flashing (the service guy told me as long as the check engine light isn't flashing it's safe to drive), I checked the gas cap for tightness, and otherwise will be bringing my car in to the dealer in the morning. It seems to be driving fine. Has anyone else had this happen? It has 350 miles on it.
