Before I take it to dealership (don’t really want to do it to a new car), maybe someone can help identifying what makes the noise. My 2017 cat didn’t have this issue. It’s a soft clunk, coming from behind me, seemingly on the left side. Most of the time I hear it right after I start the car, but sometimes it happens later. Only happens once per car start. Nothing is loose in the car, I checked, plus most of the time it happens when car is motionless. Any idea, please?
Please help. New redeye charger makes soft “clunk” noise every time car gets started.

Possibly exhaust actuator?
Quite certain it is the active exhaust valves. I can also hear this when I come to a stop as well once in awhile. I'll bypass them one of these days and find out for certain.
No, it clunks right after the car is started
Yes, if I don’t get it right at the start it happens when I come to a stop
I noticed, that when the car is hot, it happens right after the car starts. If the car is cold it happens later on a trip, usually at a full stop
Do you think if it’s active exhaust valves, it needs to be fixed or it’s not really a big deal?
The best I can describe the noise, it’s like when doors get locked, similar sound, just softer, not as pronounced
Are you sure it is not the hvac system with a blend door or ac compressor engaging?
Try it with ac on and then with everything off.

I will try, but the noise is coming from behind driver seat on the left, like around the tank or left rear wheel (unless my ears get fooled, which is possible)
Well that is not ac.
Exhaust valve
Fuel pump
Evap emissions canister

Given the possibilities, the main question I have is, can I just ignore it? If it’s a huge deal (safety issue), I’ll take it in, but if it’s a minor thing, I’d prefer my new cat not to be a subject to dealership poking.
I would make an unscheduled visit some weekday ask the Serv Mgr to come outside for a listen, and maybe a short ride. Maybe approach it like, “I hear a sound but I don’t know if it is normal or maybe something is wrong”. And you don’t want to drop it off for a day if it is just something normal.
I try to catch the SM mid-late morning, seems a less busy time. If you are lucky he’ll hear it in the parking lot and say it’s xxx and is normal.

I am glad you posted this. I have the same issue with my non-redeye hellcat charger. I’ve had it 2 months and now have 1300 miles. It’s a very strange sound. Doesn’t appear to hurt anything but it’s annoying for sure. I will probably just take it in soon.
