Gallons of Rain Water Pooling in the Cargo Area Well - Can't Find a Leak
After weeks of raining here in Southern California and self quarantining, I decided to take my 2019 Honda Odyssey Elite out for a drive. Upon opening the back door to the cargo area, my wife and I found a large quantity of water pooled at the bottom. And by large quantity, I mean several gallons worth of water. The photos I have here only shows about 10% of the water that was originally there. When we first saw the water, we freaked out and started cleaning before thinking to take photos. We highly suspect it's rainwater since the cargo area has not been touched for about a month and no water bottles or other water source was left in the car either. I don’t see any visible water damage or water streaks to the area above the cargo area so I’m suspecting that it’s coming from underneath the cargo area. Anyone else have this issue? How can this be fixed?

This is a common issue. There’s a seam that is left unsealed.
Since it’s already soaked take it to the dealer. You can also search on the board here for others that have had this problem.

There's been a couple of threads on the tailgate leaking/water getting into the cargo area. I haven't actively searched for any new ones, but here's a couple.

19 Elite - Wet cargo area
My wife reported that the van has smelled lately. When she went to investigate, there was a lot of condensation on the underside of the Honda Cargo Tray. The carpeting underneath was wet. We peeled back the carpet on the passenger side of the cargo area -- carpet and foam were very wet and...

Rear Cargo Hold Floor Pan Seam Seal Water Intrusion
For those of you with a pond in your new Odyssey, I felt your pain and discounted how minuscule the chance might be that my own EX-L might have water coming in from somewhere due to a quality issue. Then one day about two weeks ago, I decided to do my sound attenuating regimen on my new...

I remember one day I left the van in my driveway with more or less 30 grades down on inclination and the night before rain a lot the next morning I found water in front close to the transmission buttons and blue ray, only happened one time but I was unable to find from were the water coming from, some time I think maybe the sunroof was a little open or something

To my knowledge, the hole in the floor pan was only an issue with the OP of the second link.
As shrimpmoney said, there's a known issue with a seam being left unsealed. OP won't know for sure until the dealership checks out the car.
Ody tailgate holds and leaks water
Yesterday, the northeast was hit with a pretty big storm while we were on our way back from a road trip. After we stopped and opened the tailgate, a bunch of water started dripping out of the interior tailgate trim, tailgate close button/handle, and when you'd closed the tailgate, it's like...

Above is a link to my post on what happened to our Ody and water getting in the tailgate, but I don't think it's relevant to what OP is going through right now.
Really sorry to see the water in your van's cargo area. Several gallons "IS" a large quantity of water. Please let us know what the problem was when you find it. We also have a 2019 Ody and I would like to check our van for whatever caused your flooding.
There is at least one bright side to your problem. At least your 3rd row seats were not folded down into the cargo area. If it happens to our van, it will be a mess since our 3rd row seats are always folded into the cargo area.

I scored the car rental lottery once and ended up with a really nice Volvo.
I carefully parked it in the corner of the hotel parking lot, and was surprised to find the rear passenger footwells full of water the next day.
Turns out their lawn irrigation system turns on at night. One one of the sprinkler heads was near the rear of the vehicle, and had the perfect angle to blast water past the door seal.

I have a 2007 touring and had this issue. About a year after I purchased I had water in the cargo area, dripping from the seam above the cargo area and even by the windshield upper corners. Then, I had issues whenever it would rain the alarm would just start blaring. I brought to my mechanic and he took off the luggage racks and resealed under them and replace the racks. I haven’t had an issue with dampness or the alarm since then. While my van is considerably older than yours, it could be that the stuff (I’m not technical obviously) they put under the racks to make a seal aren’t seated properly. Good luck!
I just had that same problem. I called the dealer and told them I had standing water in the the trunk. They said to bring it right in. The cleaned up the whole mess, resealed and tested the whole trunk and did it all under warrantee. They even disassemble and clean one seat that had been lowered into the water. Free loaner car for the 3+ days they had the van. I'm a happy camper.

Sorry to see this OP. I feel for you because in an former car of mine I had a very large leak from a window installer who didn't do as good of a job as he should have in sealing the window. Long story very short....you can't just suck all the water out and it'll dry up on its own...because it wont. There is typically a foam underlayer under the carpet that holds water like a sponge. You need to remove the carpet to get under there, and also remove the foam to dry it out. After I removed everything from my car there was still ponded water under everything. This needs done asap to keep mildew from forming. I hope the Honda dealer gets to the bottom of the leak and dries your vehicle well.
And here I am, 7 months later, my whole trunk is soaked under the cargo liner. Taking it in Monday.
@EHondaSlap what did they end up doing for you? Just trying to figure out what I'm up against.
Yikes sorry to hear... hmm I'll keep a close eye on mine for sure as I have the rear OEM cargo tray there...
At any rate this is pretty sad news ... Honduh..uugghh
If it’s a leaking seam, I wonder if it’s filled at the factory by a human or robot. I’d wager a human. Once a robot is programed, it won’t avoid a seam unless reprogrammed to do so. I would also assume that if the robot ran out of sealant, there would be a sensor to stop the line until the robot gun was refilled. On the other hand, I’m sure the robot doesn’t suck sealant out of a small drum or tube 😊.
We don’t hear too many of these horror stories but even one is a serious issue. To find a leak anywhere in a vehicle, there’s a tendency to flood the car using high pressure from the top down and then look for leaks on the inside. I was once told by a wise person that this method is totally wrong. If you want to find a leak similar to this, you use low pressure – a bit stronger than a dribble – and start at the bottom of the car and work your way up along each seam. Starting at the top will flood several seams. When the car starts to show a leak, you don’t know which one is leaking. By going up from the bottom up, the leak shows itself right away. There’s no guessing as to which one is the culprit.

That sounds logical. If I was outside of warranty - that's exactly what I would do. Hopefully they'll resolve it at the dealer though!
I have the 19 Elite that was linked above. Our dealer took care of the cargo area leak. Over a year later, everything is fine. It was inconvenient to deal with at the time, but between the Odyssey loaner and addressing the issue, no complaints about how it was resolved.

I had this issue on a 2018 Elite. The difference is the car had been rear ended and after the repair it happened. I took it to Honda first and they had me take it to the authorized repair center. It took 3 return trips but it appears to be fixed. For our fix it was seals on the light and antenna fin in the back. It didn't appear to be coming from the sides or bottom of the vehicle.
The repair had a new hatch put in so it made sense. Crazy that it is an issue on un damaged cars as well.
