So after my wife came home today my 6 year old son came into the house and and said papa there is a noise coming from the car. Needless to say I was very proud of him that he pays attention to that at 6 years old. At any rate there was a loud whine with the engine off and then the whine went away when the engine cooled down which to me means that the fan is not working or is frozen. I immediately called my local Chevy dealer to schedule an appointment they can fit me in next Tuesday at 11:30. Should I be concerned driving the car until then? I am thinking about going in on Saturday and asking for a loaner car this is a 2014 with 11,000 miles on it. the weather right now is very cool highs in the 40s 50s lows in the upper 30s low 40's.
