I've noticed the car is basically silent at low speeds (5-10mph) except for a rattle/chatter when engaging the brake softly. It almost sounds like a low creaking. Does anyone else notice this? I usually notice it when driving around parking lots of garages looking for a space.

I noticed that too. Guess it will go away with a bit more wear. If it sticks around to the 10k service, I'm going to ask about it but it doesn't really bother me yet.

Thanks for chiming in. I agree it's not bad enough to take it in unless it gets worse. One of those noises we might hear because the car is so quiet.

My car has 500 miles on it and I just felt it start this morning while in heavy traffic. Doesn't matter if I am in EV or Hybrid, it feels like the car is having an issue engaging the transmission at idle speeds (just taking my foot off the brake in traffic.) I would describe it as a bucking like in a gas only car when it is about to stall. Car actually shakes like you are traveling over a rough patch in the road.

Going to try to drive it home this afternoon. If it re-occurs, going to call the dealer.

I think what I'm describing is something different. It almost sounds like a creaky spring when you engage the break at low speeds, with low force. You can duplicate it by going 5-10mph or so and gently engaging the brake, in EV mode with no music on and the windows up.

Though what you're describing I think I've felt too. Braking and you can feel the car transition brake systems or something.

Yup, a creaky spring is exactly what mine sounds like. And yes, I figured it was the price we pay for whisper quiet operation! Im actually pleasantly surprised there are no other squeaks and rattles. I downsized from an a4 avant and the e-tron is a really well put together car.

I guess that there is a tipping point where the brake moves from regen braking to mechanical braking, this transition may not be seamless and you may notice it more at constant low speeds.

I noticed the same on my previous Chevy Volt but I guess I'm used to it now after 4 years in the Volt and 1 year in the e-tron.

Regarding the point on juddering on acceleration at low speeds, I think that is due to the electric motor having to change drive speed as the transmission gear changes. In fact it is not necessary for the transmission to change on pure EV driving (the Volt didn't even have gears) however I presume that the gear needs to be selected "correctly" in case the ICE engages.

The electric motor in the e-tron is not separate from the gas engine and outputs it's power through the s-tronic transmission.

I just got an etron, less than 300 miles and notices small rattle/chatter when gently applying brakes, under 20mph. Is this normal? Was there ever a resolution from the first poster?
