Door seal is bad, I believe. Mine has never collected water. It's probably a simple adjustment/replacement of the seal.

On the other hand, very few cars are designed to be waterproof everywhere. Water resistant around doors, certainly. But in the span of a two hour drive in the rain, I can imagine some situations where water could be forced past the outer seal. One could do a simple test with a garden hose, attempting to direct the flow into the sill/door break and compare the results on both sides. If one side leaks more than the other, you have proof of a problem. Hopefully input from some of the long time owners will also provide direction.

Whenever I wash my car, I notice water on the door sill. Not a big deal for me.

I've never seen water accumulate like that on my 2009 sedan - rain or washing. I don't "blast it" with the hose though. I'm meticulous about hand-drying everything too; I open all doors and dry the sills, frames, the door itself, etc... I'd have noticed if the plastic trim was ever wet like that. I've never had that happen on my car.

I agree with the others that your door seal is defective. Especially if this happens on only one side of the car as was pointed out.

I wash my car with a high pressure hose found at self-service car washes. I think the small amount of water on the plastic part of the sill is normal in that case, and also with a heavy rain where a lot water splashes up from the front wheels. The seal is visible in his pic and is inside the plastic sill, so I don't think the seal is defective. The amount of water is relatively small and not to worry about IMO.

Exactly.. you can see the door seal in the picture. It is directly to the right of the water you are talking about. So its Not a defective seal.
If you wash your car and spray water through the crack under the door that is where the water ends up, the seal stops it from getting any further. It is weird that if would end up there while just driving for a bit. Unless you were getting sprayed by other vehicles a lot. But it isn't a problem. You will get a bit of water and dirt in there from time to time

OP said they were driving in the rain for two hours, so I could see that happening due to spay from front wheels or due to vehicles in another lane.

Looks like there is no water past the seal. Looks normal to me...

I just double-checked my 2009 sedan. There are multiple seals for the door openings. One is attached to the car body, just inside the sill, like the one visible in the OP's pic. This seal pushes against the door interior plastic bits (when the door is closed) and, I believe, is mostly for noise control. There is another seal attached to the door metal; this one pushes against the car body OUTSIDE the sill (along the 1/2 to 3/4 inch wide "lip" of bodywork in the door opening, just to the left of the plastic sill in the OP's pic) and should seal against water plus exhaust fumes from other cars. This seal is one that might be compromised on the OP's car.

Also, there is a "skirt" or "flap" seal hanging down from the very bottom of the door; this one seals against the side body/ground effects piece and should be a first-line defense against water splashing up and into the sill area.

Like I said, every time I wash my 2009 with a high pressure car wash wand, I get a little bit of water on the sill. I would say it is "feature" and not an assembly or materials defect (maybe a design defect depending on one's point of view). The water leaking into the trunk (when opened) is much more of a nuisance than tiny bit on the the door sill.

I get a bit of water on my sill, but definitely not that much. So I dunno As mike c. pointed out it's has double seals.

And yeah...the friggin trunk annoys the crap out of me the way water just pours in when you lift the trunk! It's just the way the curves work when the water runs off when lifting it up, so nothing you can do about it

I just looked at my 2009 Genesis is more detail. There is no outside seal on the door sil, only the inside seal as shown in the pic above. What appears to be an outside seal is just a piece of hard plastic. All of this is on the car body (door sil).

On the door itself, there is rubber "flap" on the bottom of the door that hits the hard plastic piece on the outside of the door sil when the door is closed. It is not rounded, and looks like it is intended to keep water out, but is not really a tight seal. In addition, this flap is on the bottom of the door, and some water from the sides of the doors could get down on the sil.

In summary, the outside "seal" is really just a "flap" that is not 100% water tight (as is the inside seal) and some water may get on the door sil in certain situations. Any excessive water is designed to drain onto the ground.

Erm mine does the same....just not as bad i suppose....even my other cars do these....i never knew there were supposed to be water proof lol

 

[mikec]

Mark_888: besides the flap, is there ANY other rubber seal piece on your 2009's doors? My 2009 is an early one (the "bad" suspension) and there clearly is a rubber seal piece along the doors - both the front and rear passenger doors. These seals push against the thin flat vertical bodywork sheet metal inside the door openings.

And there are "flaps" hanging down from each door. There is also a harder piece at the top of the doors - basically a rain gutter.

I also have an early 2009. There is obviously a rubber seal on the door, but it meets up with the seal on the inside of the door sil, which allows some water to be outside of that on the sil itself. The rubber flap helps keep water off the door sil, but it is not a waterproof seal (as is the inside seal).

Well here is how it played out.
Took the car to the dealer, they replaced the outer seal thinking it may be bad. Still leaked. The service mgr. has never seen this situation before. I said how can a 4 year old version of this car(No One) has seen this before ? I told him that's hard to believe. He said they will take the panels off and watch the water. Turns out Service mgr called out to california and talked with an engineer. He stated there could be water on the lower sil under the right conditions. He then brought in a RSPEC in and ran water on the window right where it meets the door, after a few minutes there was the water on the sil. So my guess it's a design flaw or was designed that way !! In all my years of owning different cars, I never ever would see water puddle on the sil......Thanks for all responding.....

I (and others) already explained that there is no manufacturing defect and it is normal. I think you are exaggerating when you say "puddle" (looking at the pic you posted). Looks like a few drops.

If you lay on the ground and look at the underside of ANY car door you'll see drain holes on the bottom of the door frame. These are the drains for the water that runs down the inside of the door from the seal at the bottom of the windows (which is just a rubber strip so it won't keep everything out). Looks like that's the water you're seeing pool up in there since the Service Manager did the same test.
