I had the same thing it is piston slap the motors come factory with low tolerance so when the motor is cold the parts shrink and then when you drive it you get a nuts in a coffee can sound ....The motor is bad talk to your dealer there is a bullitin out but they don't admit it to easy for obvious reasons. they told me it can fixed by a timing adjustment.....but I thought it was bull so I fought them on it....
