Metallic Engine Sound on Cold Start
I have a new 2017 Crosstrek Limited with about 75 miles on it. I noticed that when I start the car in the morning each day (weather is about 35 degrees outside), there is a brief sound (less than a second) that sounds like a metallic grinding sound. It only happens when the car has not been turned on for several hours. Is this normal? Any idea what it might be?
