Strange noise after shutdown.

[Maintf16]

Just curious if anyone else’s truck does this. It’s always happens a few minutes after turning the truck off.

Never heard that one before... Do you happen to have air suspension? Sounds like it could be a compressor purging.

Mine does that too. I was told it’s the electric parking brake or fuel pump calibrating. Never been decided which.

Mine makes a noise similar after it sits for a minute after shutdown. I'm not sure what it is. It was discussed on here before, but I don't think anyone figured it out. My only thought is it has something to do with active dampening.

does it do it when you push the start stop button?
or when you put it in park?

it would also help if you tell us what you have.

Mine does it about one minute after turning the motor off. Seems to only happen after longer drives. I assumed they all do it.

Mine makes a noise sometimes. No air suspension. Still don’t know what it is

Do those that hear the noise posted, have auto parking brake enabled? I went out and toggled the setting on and off , and believe that is what is making the sound.

Which engine do you have?

I started a thread awhile back about this.

Loud screeching noise from back of truck….fuel pump?

Not sure how often it happens but I caught it three times now. It happens just a few minutes after a long drive with the ignition off. Sounds to me like it’s at the rear of the truck and likely the fuel pump. Pretty loud and lasts for only a few seconds. Not sure if it goes thru some type of...

Thanks I think there is yet another thread about this too, but I couldn’t find it.

Glad to hear its not just mine that does it. I have a 2021 1500, 4x4, 5.7 etorque, built to serve edition. oh and I do not have my parking break set and I have the auto backup brake thing off (hated that thing, scared the crap out of me too many times) not sure if that matters. Happens after shutting the truck off not into park. Noise appears to come from rear passenger area.

 

[asgadf/lkjnadsfg]

Yep, mine does that.

 

[HEMITKN]

Same here thought it was the brake or air damn thing.

i noticed this last year and posted about it, i noticed it pumping gas
multiple times, sounds like an acuator motor
or
something, nothing to worry about all normal

 

[Mountain Whiskey]

The brakes activate right away when you throw the knob in park. It should be done before you hop out of the truck. This is probably not what you are hearing when pumping gas.

Mine does the same thing and so does my wife’s Highlander, FWIW.

Wish someone from Chrysler knew wth it is
