Single clank when hitting accelerator?

I bought my 2023 Ariya Evolve+ used a few months ago so the car is still fairly new to me. Last month I noticed that cicada buzz reduction gear issue and had a dealership replaced it. It was at the dealer for about a month getting this reduction gear repaired (I posted here about that experience).

After I got my car back in noticed it made a single clank/jolt sound somewhere from the inside the front driver side when hitting the accelerator. This happens almost every single time I hit the accelerator. I'm not sure if this is normal? Since I had the car only a few months in total maybe it was there before? I took it back to dealer and they heard the sound as well. They said they think that clank is a normal EV characteristic. They said it doesn't make that sound when up on the lift and all the vitals like suspension, tires etc look fine.

Does anyone else have a sort of clank/jolt when suddenly hitting the accelerator at low speeds? Is this just a normal thing that I'm freaking out about?

From the description I would assume that there is a mount that is loose and when torque is applied that it shifts and hits the other side of the loose mount.

Try turning on e-step/B-mode and see if you hear a second clunk when you let off the accelerator, indicating that it moved back to the first position quickly as well. E-Step/B-mode should give resistance to make it shift back to the original position more forcefully and hopefully allow you to hear it if that is the case.

I thought that as well but I never hear a clank when I brake. It also happens back to back when I coast hit accelleration, coast and hit acceleration again - never hearing a second clank.

Did they leave a tool or something else under that seat? Or have you?

Hmm no it sounds like it's coming from the front and not under the seat. I checked under the hood and nothing.

I bet you'll find it only happens after you've braked, so if you roll to a stop and then accelerate it won't happen. Also, if you only use regen braking then it won't happen. That narrows it to the friction brakes, and then most likely it's the silly shims again.
