Electronic Servo sounding noise when parking and after shutting off

[Firmie]

Get a weird like servo noise when I park or after I shut the LC down. So noticeable a passer by commented there are a lot of weird noises coming from your car. uhhh, I just picked it up yesterday. Any thoughts? (first time poster) Thank you.

Our Highlander Hybrid does the same. I think just the hybrid systems shutting down. In fact, it seems in the owner's manual there is a blurb about noises, even after the vehicle has been parked for some time...

ahhh yea thanks, I was guessing that. Of course I have't had time to read the manual. Next on the list.

It's probably, among other strange noises, the electronic parking brake engaging.

Yes it’s normal and the parking brake sets my tundra hybrid did same thing

It's the parking brake. Makes a space age Jetsons like whirring sound.

I have the same noise but it doesn't happen all the time. I was going to reach out to the dealer to have it checked. It makes a whining noise when going into park. Not all the time but enough to be curious. I just hit 1500 miles

there is a purge valve sound as well. I was told about it when we were at dealer

Try engaging/disengaging the parking break to see if it is that.

You should hear the ruckus a Tesla makes. So I chalked the LC noises up to hybridy-stuff.

My non-hybrid Tundra does the same thing

Any update on this?

It is 100% the electronic parking brake engaging. No worries. There is nothing wrong with your LC. As soon as you put it in Park and hit the engine off button, the parking brake auto engages and makes a pretty distinctive noise. Especially if your car is still moving a little from bumping a curb stop or something when you put it in Park. It just locks the wheels tight. Completely normal.

I get this sound. Only happens when I come to stop and in drive. It i shift in neutral it goes away. If I shift in park no noise. Comes only when engine does it's auto stop and goes in to hybrid mode. When I put load on the hybrid noise goes away.

@jambo Damn, that sounds awful! I'd go straight to the shop.

Unfortunately it does not make that sound at the dealer lot.

Did you show the dealer that video and noise it made? If so, I would be curious to know their response.
