So we did the recall update mid Sept. Ever since we get a clicking noise after the van has been driven for more than 20mins. Generally I hear this when on electric only, might happen with gas but alot harder to hear. Coming from between the mid and rear row assuming rear battery area. Can be heard from interior and exterior. More so on exterior/rear of vehicle. Its a cycling noise of on/off, some sort of pump. Is there a rear coolant pump for the battery, or maybe this is a the fuel pump? Van drives fine however this is the most annoying sound ever.

Anyone else?

I started noticing what I am assuming to be the same noise just this week. Van drives fine, but I am just sure exactly what is going on. I noticed the noise as I was pulling into the garage a few days ago, but noticed it again today at a stop sign.

We've dropped off our hybrid to get this checked out. I'm going to guess either recall did something to how the fuel pump modulates or bad fuel pump. I can't find any information on the battery if there is a pump directly on it towards the rear of the vehicle.

Got an update today, I'm told its the fuel pump and normal after the recent recall software update. I'm told maybe I just now noticed it or started hearing it more due to cold weather (currently 20f outside).

Hi,
Any conclusive result? We took ours in last month and the dealer said they can't replicate the sound. Ours is very low that you can only hear it when idling. We are in S. Cali so it can't be due to weather.

I haven't seen this issue moving forward, my vehicle had the noise happen in the Run mode now. Pressing “off” on the climate control stopped it, and it didn't return.

I’m going to try a couple approaches when I have time. Otherwise have a read over the other thread.

Well heres a graphical view of the noise seen in wiTech 2.0.

Unfortunately theres no flashes available and I wasn't able to reset the control unit from tester.

I’m going to powerdown the 12v to reset the control module and see if this has an effect

Ignition OFF

Ignition ACC to RUN

Yes, I have heard that noise for a few months now. I brought it in and it said it was normal. But there is no way this is normal....
I have been in the process of moving, but will bring it in again in a few weeks. Any advice? How can they fix it?

The recirculated air flap motor “Actual position” deviates from the “Target position” in my screenshots on the tester.. This means the actual position is bouncing all over when the HVAC module demands no movement.

It simply cannot be “normal” or the target position would mirror the actual position plots.

In this situation where the dealer says its normal, and gives it back.. there are 3 sceneros i can see at play.

1) they compared it to another and it does it too. But it doesn't mean its supposed to. It definitely is pretty common.

2) they dont know how (or want) to fix the issue and are trying to pass the buck to see if you will go away.

3) or its a known issue and there is no fix available yet. And they’re buying time.. but they should just tell you up front and call you in when the fix is available.

Best talk to the forman, be friendly and show him the noise and what changes the noise ie: pressing the recirc button.

If they want to force the “normal” card ask them to prove its normal by printing all the flap motors actual vrs target position graphs from the tester (like i did) and see what they say.

If you just bring it in again without talking to a forman you might have a repeat experience time and time again if they don't check that its a repeating issue.

Good luck.

Good news!

@[email protected] has reported this issue is resolved with replacing the recirculated air actuator in post 23 in the Pumping or Gear turning noise while parked thread (linked below)

I don't think we're all talking about the same noise. Mine is coming from the rear of the van, not under the passenger side dash. I was also told mine was the fuel pump and this is "normal" I don't buy it, if its the fuel pump and its circulating that much why is the fuel rail losing that much psi to cycle on/off every 2 seconds.

I thought of bringing mine in again to have a second opinion from the new dealer I've been visiting.

Noises are hard to localize and communicate in general. But the noise in the video and discussed since post 11 has been reported resolved to be more accurate.

Why not make a video of your “rear of the van” noise so we can fully conceptualize the issue.

Maybe we can help.
