Model 3 Wake Up Noise

[jc22zhao]

I noticed that everytime the model 3 goes into sleep, then wakes up. There's a fairly loud clank coming from the car, near the floor (batteries).

Wondering if other people experienced the same and whether I should bring it up with the service center?

Also, I noticed that sometimes when I apply brakes near the start of a drive, there's a light clanking noise as I (or autopilot) press the brake pedals. Is this also normal?

Its normal. You'll also hear noises when you supercharge.

All normal. ICE cars make a lot of those sounds too - you just can’t hear them over the sound of thousands of small, mostly controlled explosions per minute.

Contactor closing. Perfectly normal.

I've read that it is the relays flipping back to allow power from the batteries. Perfectly normal.
