Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

i dont like it either. i dont think you can do anything about it. i heard it helps cool it down also
There is a ticking sound that you get from the metal cooling down when the car is turned off. The ticking sound at idle I have always attributed to the exhaust system. It sounds like there is some part of the metal that is flexing or moving to produce the "tick". It doesn't bother me though. I'd take it in to the dealer and have a tech take a listen to make sure it is something benign.
Just as Fadiboy said. And from searching a previous poster (Silversled) said " Stainless exhaust, heat shields and hardware make a pinging sound when expanding or contracting relative to each other from heat and cold. This is normal ." That is when the car is off. If you are hearing a pinging when the car is running it could be a problem of some sort. As another poster (ChrisR) put it " The bad ping is the kind that is also know as detonation: when the air and fuel mixture in the combustion chamber ignites before the spark plug lights it off in a controled manner. The 'ping' you hear is the sound of the piston rattling down the walls of the cylinder wall. Not good."
The sound I get when the car is cooling down is more of a "ping" or "ting" sound.
i do have stainless exhausts , so this might be the problem .
