Thank you everyone! This thread has been very useful for me.

My 2018 PacHy also started to produce this noise 6 months ago.
Only seemed to happen the moment I turn off the the engine.

After studying this thread I took my vehicle in for service.
I told the service coordinator about the sound and that I think it might be the recirculation door in the passenger footwell.
Although a pretty nice guy, as expected he said "well you see, these hybrids always have some motors and pumps to keep cooling the battery even after the car turns off, probably nothing to worry about".
(I knew to expect that response thanks to this thread.)

I insisted that the sound has been getting louder over the 6 months.

The service coordinator brought in the lead mechanic/foreman to come and listen to the sound. He said he thinks the blower fan is continuing to run, which it should not, so he agreed to take the glovebox off and look into it further.

They called me to tell me that it is in fact the recirculator door actuator, but the new part will need to be shipped in, so another 2 days. Finally, all fixed.

Again, thanks everyone.

Pumping or Gear turning noise while off/parked and plugged in.

We have been noticing that the Hybrid has a low pumping noise that seems to come from the center of the dash board when the van is parked and charging. When I turn on the van the noise stops. It seems like this noise only starting happening recently Dec. Jan. and I am wondering if it is related to warming the battery or some other maintenance system keeping the oil circulating. I took a video that has the noise but do not know if we can upload a video here. There are no warning lights and the van seems fine otherwise.

Anyone else notice a similar noise from near the dash?

I have yet to try and document if the noise also occurs while not plugged in yet.

Edit.

I had U73 done in Dec. and never noticed the noise before that.
I have noticed the same noise in my 2018 limited Pacifica after opening the door before startup and after engine shut down, looking for answers?
