What is this sound after turning vehicle off?

[Nels]

I'm just curious - my truck makes an unusual sound about 30 seconds after I've turned it off and gotten out. Sounds "electronic" like something powering down. It seems to come from the back half of the vehicle, or maybe it's just resonating through the bed? Can anyone tell me about what this? It's not a concern, I would just like to be able to tell my wife what it is so she can go on believing the fallacy that I know everything about my truck, like a real man should! LOL

I've wondered what that is as well.

Most likely it is the parking brake engaging. You can turn it off in the settings if you wish.

This sounded legit so I checked my settings. Auto Parking Brake is not checked.

i think youll find its the system computer going through its post trip shut down

Do you have air suspension? It may be doing a self leveling adjustment.

 

[Nels]

No air suspension. 2019 Laramie. My brother's 2020 BTS does the same thing.

 

[Rammit]

Mine does to. I believe part of it is the parking brake and some type of shut down check

 

[zlman]

Mine does the same. 2 sounds actually, 1 is the p brake, the other, no clue, an electronic beep of some sort.

The e-brake is almost instantaneous if you have it to auto set when you rotate the shift knob to park.

I do hear hvac blend doors closing under the passenger side of the dash a good 30 or so seconds after I turn the key off. That could be one of the noises you’re hearing.

It's the Flux capacitor recharging for the next time warp....

 

[gpbst3]

I believe it some sort of auto vent with the fuel system. My previous Tundra did the same thing

It's tallying up the miles left to the end of the warranty period and preping for self destruct mode.

Mine had a whistling sound coming from the dash after shutting it off. Turns out it was a thermal expansion valve.

It is the fuel pump

It is the fuel pump

Given the location of the sound, the fuel pump sounds logical.
