If it was the CHECK OIL LEVEL message and you had the oil changed, he may not have put enough oil in it. The Northstar takes 7.5 qts. (most cars hold 4-5 qts).
The message comes on when you are about 2 qts low.
Check your dipstick. The proper oil level should be about midway in the hash marked area.
