After driving my car for about 30 minutes maintaining a speed of about 60 to 65 I keep smelling coolant from underneath the hood when I get out of my car. Also my engine sounds a little rough from when I bought it. Took it to the dealership back in April they said it was normal that the engine was breaking in. Taking my car back to dealership tomorrow let's see what they say this time.
