Electronic hissing noise when hitting the brakes

[02sahara]

Hi y’all,
I’ve got a ‘21 Willys that I’ve noticed an electronic hissing noise when the brake pedal is pushed, or released when in park. This happens when stationary and when driving I’ve noticed. Has anyone else heard this?
Thanks!

Sounds like the ABS module. I have a 2021 Willys and do not hear any strange noises when braking.

No noise at all when you step on the pedal when you're in park? I noticed it one other time when I was in the neighborhood with the doors off but can't hear it when driving or moving. I'm waiting for a key to come in to the dealer so I guess I'll have them take a look when it finally comes in.

This is normal. Its the newly designed vacuum/pump near the engine. You will hear this in any new JL or JT.
