when i installed the rear camera, i pulled off the lower part of the door seal. i had it on/off a few times, so i could close the door, and go take a nap. a couple days ago, i powerwashed the car, and the right side, which i did not touch, did leak out some water, but the left side was dry. ima keep my eye on it, and perhaps if it stays dry, i can get a part time job at hyundai

Have any found a solution to door drain issue with the 2020 Sonata Limited. It rained a lot here Fayetteville NC the last few days and my car captured a lot of water between the door and the body frame of the car. I had to remember to go outside and open the doors to release the water. Thanks for any and all responses

I'm playing a game of "Which one of these is not like the other?" to try and see if I can determine why one door has the issue and the others do not.

Check to see if your vehicle has this "defect". Might be one way water is getting in the door.
Anyway, in the photo to the left of my finger, there was a small area (maybe 1") where the rubber was not fully seated in the track along the chrome strip. This is at the top corner of the door. It was noticeably different on the door that has (had?) the issue than the doors that did not. Yesterday, I seated it properly to match the other doors. It rained last night and we got a heavy downpour this morning. I just checked it and "voila" no pouring of water at the bottom.

This wouldn't explain why water is getting trapped at the bottom of the door, but just maybe how it is getting in the door?

UPDATE: Ugh! Today I ran the hose only in the space in the bottom chrome strip (See post #51 in this thread) and the water did get dammed in the door. A few observations, however. When I run the hose nozzle on low in just that area while the door is open water does come out both of the weep holes in the door AND the weep holes in the weatherstripping. I believe what is happening is the water coming from the weep holes in the weatherstripping is getting trapped. Not sure how to fix it. The chrome strip part is now at my dealership. Maybe this will prevent water from getting in?

The same area looks suspect on mine as well. Re-seated and we'll see how it goes.

Those of you following already have your Sonata - but I haven't made any deals yet. I'm just curious, for those with the problem, if you feel it would have been a deal breaker had you known about it before?

Absolutely not a deal-breaker. I LOVE this car and am so glad I bought it. Are there things I would change? Well of course, but none of which made me think twice. No car will be 100% perfect. But I can attest despite the small issues I have with it (such as the advance track button is down and not up), none have made me question the purchase. Saying that please know that everyone has there own opinion on what is important to them. My important must-haves were technological aspects. It has all of the tech I wanted in a car and is affordable. I so much love driving on the highway and not having to do much steering or peddling. The car literally drives itself (as long as there are lines on the road). Blindspot cameras, full vehicle video, heads-up display, huge touch screen, heated and A/C seats, and so on. But you have to decide what is important to you. I paid extra for the premium specs. Not everyone wants or needs it.

But, if you test drive one that has the water issue, try to use that to get a better price. I love the dealership games and haggling.

Well the one I picked up Monday didn't have any water in the door. But they detailed it so it was probably cleared of any standing water then. And I keep it in the garage...I'm I've been working remote since March, so I haven't parked outside in awhile. It'll be some time before I even put it to the test. But I can live it with it if it does do it. Love the car!

UPDATE:
The dealership (per Hyundai's instructions) installed new weatherstripping on BOTH rear doors, the weatherstripping is between the door and the car. I was only having an issue with the rear driver's side door. I did not request these to be replaced or ordered, but much to my surprise when I picked up the car these are what were replaced. I can report that I STILL have the water issue. I've reported this to Hyundai.
Interestingly, the Belt Molding that I wanted replaced (refer to my video where I believe the water is getting in) was on back order and not replaced. I now have a part # for reference: 83210-L1000. The part is now in stock and will be installed once the TSB is available for the wind noise issue.
I'll report back once it has been installed.

Looks like the part 83210-L1000 seemed to do the trick. Instead of 2 cups of water pouring out after a heavy rain, now much less. Much improved(but not bone dry). That's two hits for Hyundai: #1 fix for wind noise issue and #2 for the water issue. Even more satisfied with the vehicle now.

Good to hear they may have found a solution!

I just purchased a 2020 Sonata and after a heavy rain the driver side rear door drains a large amount of water upon opening. None of the other doors do this, just wondering if anyone else had similar issues. Plan on taking it into the dealership the first day I'm able.

I just purchased a 2020 Hyundai Tucson and I have the same problem on all four doors . I took it to the dealer and the service manager said there’s nothing they can do it’s a manufacturing problem.Im now trying to find the next step.

I love the splash. Not sure why but it catches me by surprise everytime.

My dealer wasn't cooperating either. So I called Hyundai Consumer Affairs and made an official complaint against my dealership. The next step was to take the car in 2 more times for a total of 3 attempts so they could escalate the case.

Before I could do that, I received the automated survey that comes to my email after a service appointment. When I submitted it with my brutally honest review and 1/5 stars, I got a call from the service manager literally 2 minutes later. I was surprised to learn they actually saw these things. I told him about the other people here that have been getting their problems fixed with no hassle and he actually asked me to bring it back in. They called the "engineers" again and got the approval to replace some of the parts related to my issues for "customer satisfaction" reasons. One of which is parts for the water issue. I'll be providing an update in my post here about it when it's done.

Wow a sickening display of dealership service. Do they wonder why Tesla wants to go dealership-less and of course the dealers are fighting it all the way arguing what are the poor consumers going to do when they dont have us to go to. Well who needs them when they offer service like this.

There are good and bad dealers of every brand. I'm on my fourth Hyundai in 7 years and the Sonata is the first I didn't buy out of state. Why out of state? Because I live in a city/state with few Hyundai dealers I've always gotten better deals with far less "what'll it take to put you in this car today" than I would have if I bought locally.

I live literally a mile from a Hyundai dealer. I loathe them. I drive 12 miles to another dealer for service where they treat me like a God. They'll give me a free loaner for an oil change so I can drop the car in the morning and pick it up after work. They are communicative and always error on doing what's right for me vs. the classic "unable to replicate." The service department doesn't care that I didn't buy the car from their dealership.

I did end up buying my Sonata from the dealer I loathe because I got the price I wanted and it was convenient. The sales-side was actually pretty pleasant. But nothing will get me to use them for service.

For those of you with issues - drive 12 miles and find yourself a dealer that gives a crap.

 

[weigojmi]

I took mine in to the dealer I don't loathe for this issue (among others) and they had no answer for this one...even after some water dumped out after the car wash. Said everything looked "good". One of the advisors has the same car and said he would look for this in his but didn't think much would change without a TSB. Well at least its a documented issue now...

I had this issue with my 2020 Sonata same door and I took it to be serviced. They said it was a design flaw and as long the water wasn't getting into the car (carpet) it was ok. I told them it's not ok with me so the service department replaced the moulding on the door. It fixed the problem and so far no more water. Be persistent with the dealership.

Love it. BOSE Stereo is a huge upgrade compared to the Infinity Stereo my 2015 Limited had. This thing has so much tech. Read some people think it's overload... but I don't. Nice having two phones paired. Fiancée can be paired up to the car and play music phone her phone while I drive. The **** thing can drive itself. I was very impressed by how well it stayed on course around bends and turns of the interstate. Drove 100+miles home from the dealership Friday night and driving mostly 78 mph home, I got 35mpg. The ambient lighting that runs in the cabin is a nice touch. It's not in your face but you know it's there. Vents may look small but they really put out the air. Gonna be nice when it gets really cold this winter. Having remote start on the key fob is nice. Also, glad the key fob is no longer that ugly brown color.

Only downfalls... Wish it still had heated rear seats and also the Window shades in the rear seats. There is a little wind noise in the cabin when driving 70+mph... but not much worse than other cars I've been in. Driving around town I don't notice any sound. The BIGGEST downfall though is the Light Gray headliner that comes with the Black Leather seats. Why?!?!?!? Should have 100% stayed with the Black Headliner when having Black seats. As a guy who kind of has OCD over this stuff.... it bugs me.

The main reason a lot of automakers use light coloured headliners even in dark interiors is that it gives the feeling of ”open” and roomy... feedback shows that lots of people find black or dark headliners makes the interior feel smaller or claustrophobic.

UPDATE: We had torrents of rain yesterday, sometimes horizontal. I checked this morning and no water was retained in the rear door! Looks like the problem is fixed.

Excellent news! I can only hope the same for mine whenever I get it back. They've had it in the shop for over 2 weeks now.
