2016 weird noises after shutting off

[rockwind1]

just got this rig, love it but while doing to wheeling the last few days, i noticed when i shut it off (it is really quiet out in the woods) i would heard a faint 2 tone whistle. hard to describe, lasted about 3-4 secnds. also, sometimes i hear a whirring noise, like the fuel pump is still running but i don't think it is the fuel pump,, it was from the area of the spare tire though which is close to the fuel tank.

the faint whistle starts a few minutes after shut off. maybe it is a very quiet version of the a/c system equalizing. i k now what that sounds like on older cars,,,,

anyone know if weird sounds are normal after shut off.

it's in the stickies, and also in the manual under "for your information".
It's part of the evap system, and it runs several hours after your vehicle has been parked. Totally normal

noise comming from the rear of my 4runner limited - Toyota 4Runner Forum - Largest 4Runner Forum

There will be a short noise in the engine bay, which is the air pump shutting down. The noise in back is a leak detection pump. Both noises are completely normal as described above.
