I've had my 2016 wrx for the past two days and noticed my clutch started vibrating after I drove it to work. It vibrates subtlely when pushing it in/out, enough to the point that my foot was buzzing for a few minutes after driving. Is this normal in the break in period? I have not driven the car hard at all (never past 4rpm) and have not noticed anything else wrong with it. I never felt this before on my previous MT Impreza.
