Loud clunk

[Jackyche]

I've noticed that after driving in the rain and parking the car in the garage, and driving again the next morning, this happens:

When shifting to reverse, the car doesn't move (no creep). Then pressing on the accelerator pedal lightly, it then moves but with a fairly loud clunk sound. Perfectly fine afterwards.

I mentioned this to Tesla Service and he said its from rust in the brakes??? And its perfectly fine.

Does this happen to anyone else? And does it really sound perfectly fine to you?

Yup; it happens and it's fine. (Well, it would be better if it didn't happen; but it's not a big deal).

It happens on other cars too, but more on the Roadster because you often use regen instead of the brakes, so they are wet AND cold when you park it - the water doesn't all evaporate off.

Happens on my ICE car if I haven't driven it for a few days and it's been wet. If it's been a couple of weeks, there's a noticeable jarring as well which really freaked me out till I figured out what it was.

Me too...Just drive a few metres slowly with the brake on lightly...that will scrape the rust off...

That's the sound of your battery pack falling out.

No, seriously, my Roadster did this all the time. It's just the brake pads getting "unglued" from the rotors. It's much better, though, since I switched to the Carbotech AX6 pads.

Thanks guys. I feel better now. Although that's a really loud clunk. Figured anything that loud can't be normal. Oh well.

Yep, perfectly normal w/ high iron rotors and stock pads. As Doug says it's less w/ the Carbotech pads (I'm using the 1521's) but still there.
