I am sure there absolutely has to be a topic on this, but using search with "sloshing" didn't bring up much and I can't figure out what else to call it. That said, I can hear tons of water somewhere behind the dash/firewall area. The interior is completely dry, so I'm guessing it's just a drain that's full of debris in the engine compartment. It used to be intermittent and would go away after driving a few minutes, but now it's a constant thing, particularly since we have had a mix of rain and warm weather which is causing tons of debris to come down from the trees where I park.

Can anyone point me in the right direction? It almost sounds like my friends Touareg that seemed like it had over a gallon of water in the frame when we finally opened the drains.

Probably clogged up sunroof drains, get under the truck and start pulling rubber plugs from the frame/body out till you find the source. You can run some heavy weed whacker line down the drains to clean them out so it doesn't happen again.

Probably going to sound stupid, I was so sure it was in the engine compartment that I didn't bother to check the underside anywhere else. Thank you.

Agree. Sunroof drains, but also check the A/C condensation drain. There are two of those - one up front, and one in the back for the rear A/C unit.

I am just now about to get to this today, but I suspect that is what it may be. The sloshing got really pronounced in the past week since warm weather finally hit and the AC has been on. Also just realizing there is no water under the after I park it like would be normal.

There is a rubber hose in the engine compartment on the passenger side you can see it from under the car. That is the condensate drain easy to pass a snake or a plastic dowel up and into . In fact they make a spray can that has a nozzle on it that plugs into the rubber hose and when you press the valve on the can it sprays a cleaner and disinfectant up inside and that does remove odors etc. You can buy it at the dealer or buy it on line . The rear condensate line is also visible but I forget which side it is on.

Passenger side, near the rear bumper.

I have the same problem with my GX. Sloshing water. Sounds like it is coming from under, infront of the passenger seat. Thank you all for the inputs!!!

I just got my 2017 GX and i hear this noise during sharp turns... does anyone have a picture or a slight better description of this hose? or plug area? or diagram they can point me to?

I dont want to start just pulling rubber hoses...

thank you all !!

Try posting in the GX460 section since you have a '17, the principles are the same but we don't have 460's to share pics from.
