That sounds like my '13 300S, 85,000 miles. Kinda sounded like exhaust leak. Took it in and they found 5 bad rocker arms, they replaced all 24 with an updated part, all under warranty. I had them change the plugs and PCV since they were already in there and saved a few bucks on the maintenance. I traded it off shortly afterwards not because of any engine concern but found a smoking deal on the '16 300 I have now.

I have an idea if they cracked my motor open, most if not all rocker arms would be bad. They said they were all good when I was still under warranty. Time to just sell it. I'm due trans service & tune-up right now.

I wonder if the later 3.6's still have this issue?
