Retorque your wheels and see if it helps.

Okay-thanks. Did you have the same problem?
No but there have been a bunch of posts about low speed clicking and the general consensus has been the wheels needing to retorqued quite often. Worth a shot.

Does it give you one click (per side) or is it constant clicking while you back up?

Does it do it going straight, while turning, or both?

If you touch the brakes, does it stop?

2021 ScatPack Wideboy A8 clicking sound in reverse What could it be?
I assume you have the 6 piston front brakes? Also 2 piece rotors?
So i had this same issue with my 2020 widebody redeye challenger. Its a known issue common with the 2 piece rotors. There are 4 fixes for this issue.

1. Retorque as others have stated.
2. Remove wheel and clean the hub which someone on these forums has done and said it worked but once you drive and contaminants enter the area it could happen again.
3. Dodge has a TSB on this issue and recommend to add a disc friction plate which i believe is like a shimmy or something.
4. Change your rotors to a one piece rotor.

Note: I ended up replacing my front brakes with smaller 4 piston calipers and a one piece rotor to have the demon wheels installed and I no longer have clicking noises while backing up or while driving at low speeds. I didnt install the smaller brakes just to get rid of the clicking i really wanted the 18 inch demon wheels and the only way they would fit is to have the smaller brakes. I will post a pic of the TSB that the dealer ordered me a disc friction plate for the front brakes but i never installed them since they were on nationwide back order.
Hopes this helps.

Turning -yes. Straight-I'd say no. Repeated clicks while I back up. Stops when the car stops.
Does the cliking stop when you apply the brakes or does it continue to click when you have pressure on the brakes? If it clicks with the brakes applied, it is probably not the rotors/brakes.

What you have described fits the symptoms of an unhappy limited slip diff. In the old days we would add more or a different friction modifier. Now they have fluids specifically formulated for the lim slip diffs. You need to see the dealer and let them hear it. You may need a fluid change or there may be a prob with the diff. Then again, if it is very new, it may break in, but let the dealer hear it and put it on record.

Seems to stop when I apply the brakes
If it stops when the brakes are applied, then it points to the rotors/brakes. When I have a question like this I tell the serv manager and he comes out and checks it in the parking lot before scheduling any service. Let us know what you ultimately find.
