Cold start "clinking bottles" sound normal? 2019 WK2 TH 13kmiles

Hi everyone. I have a 2019 Grand Cherokee Trailhawk with 13k miles. Checking to see if this normal...

On cold starts, I noticed a sound that can be best described as bottles clinking; not really a rattle. The sound is very slight... hard to hear unless in a garage and the sound goes away in less then a second. After an oil change, for the first 2 or 3 cold starts, the sound is a bit more pronounced and lasts for about 1- 2 seconds. I worry about a valve or oiling problem (?) and would want to get it resolved while still under full warranty.

If you think it is not normal and recommend taking it to the dealer, what do I tell them? (TSB's to reference, specific things to check, other symptoms I might be missing, etc.) There are so many stories about dealer techs "not hearing" noises.

Thank you in advance.

If its what I think it is, this sounds seems to be fairly common. As long as its just the first 1-2 seconds, i wouldn't worry too much about it. The dealer will probably say the same thing. You can search this on google (the 3.6L is in a lot of different FCA cars). It something to do with the oil draining back on lifters and/or piston slap because of the light weight oil.
