Vehicle has 30,000 miles on it and the check coolant level warning light has been coming on. Took it to the dealership and first was told it had a coolant leak and needed a new thermostat. A little later the dealership then apologized and said that was for a different vehicle and ours was just low on coolant. I was told this is not abnormal as fluids need to topped off periodically.
