Just got my car yesterday, and it's everything I hoped it would be! However, the quiet while driving is definitely something new.

Every so often, I'll hear a thud thud thud thud kind of noise. Is this road noise, or could it be something like the brakes sticking or warped rotors or something I need to have the dealer fix?

Thanks!

Hard to say if it's normal without hearing it. Can you make a recording?

Put it in neutral and step on the brake. If it make the noise then it's brakes. Do a half dozen stops in neutral from 60-10 to clean off the rotors. Mine had brake noise and vibration when new from sitting, but after doing the above the brakes are smooth and silent now.

Coming from a Tesla Model Y here and noticed that anything on the road (pebbles, etc) get thrown against metal somewhere in the wheel wells. Both cars have that flocked style wheel well lining so not sure what's getting pelted under there.

Where would one even go to do this? Seems like it might be a little dangerous to do on the highway....

This is probably what it is. It's pretty faint (hard to hear in any recording I've been able to make) but it sounds so loud to me, probably because in an ICE car it's muffled a lot by the engine noises.

Hard to say if it's normal without hearing it. Can you make a recording?
Sorry about the long delay, it's been hard to make a recording, and even harder to figure out how to share a WAV file on here. I can't even really hear anything from the recording, which probably means that it's just road noise and I have sensitive ears, right?

Anyways as far as the recording goes:
Does this work? (Note, the noise within the first 7 seconds or so is just me moving my phone around)

I'm rural so that's easy, but if you're in a city you might have to do it at stop lights. Shift into N when the light turns red and use the brake pedal to stop like an ICE car. Doing that for a half dozen stoplights should clean up the rotors. Neutral disables regen so you get pure friction braking. Shift back to D afterwards.

Would it eventually smooth out from normal driving even with Regen braking? And is there a way to visually confirm if it's the brakes needing smoothing? Not sure I wanna put unnecessary wear on the brakes if I don't have to :)

Easiest way to tell if it’s the brakes is to try stopping in neutral, you’ll know right away if you feel vibration. Mine wasn’t smoothing out with normal driving so I did the neutral thing for a day or two and that completely smoothed it out. A dozen stops isn’t going to make any measurable wear on the pads. Just stop at a normal rate.
