I just bought a white Genesis Coupe 3.8 Track about 2 months ago and i love it, but there's one design problem, water leaks in on the passenger side foot well. The first time i noticed this was after we had a pretty good rainstorm and there was about a cup of water on my passenger side floor mat(they're rubber mats so i could see it). And I didn't think much of it but i would keep an eye on it. After our latest storm i could obviously tell water was dripping in. So i immediately took it to the dealership where i bought the car where they could check it out. They ran it through the car wash 3 times and it never leaked, but when they put water hose on the windshield so the water could run down into the area where the fresh air for the a/c is taken in and it leaked. The fresh air intake for the a/c is located at the base of the windshield area. If you open the hood and look at the back of the engine compartment you'll see a rubber seal that seals the rear of the hood and directly behind that seal in the middle of the car are about 20 or 30 little holes, and that is where your fresh air is being taken in. Now the area around this intake does not adequately drain water, which leads to a back up of the water and causes the leaking to occur(the leak only occurs when the car is parked, not moving). People with carpet mats probably dont notice this because the water is a limited amount, but its still water coming into your car. Hyundai said that they had no fix to this problem yet, but it's a factory defect and they need to come up with one soon. Keep your eyes out for water guys!

Interesting, I will look for this in the spring. 2 summer seasons so far without this issue though, and I wash by hand with A LOT of water.

I have the rubber seal at the base of the hood removed and no leaking in mine. It sits all winter out in the open too.

There's a possibility the drain tube for the a/c filter system got clogged up with debris and mold causing the condensation to build up and overflow leaving it no were to go thus leaking water on the passenger floor board. I've seen it happen with many cars, some were brand new. The way to fix this is to blow pressurized air in the drain tube to free up the debris and mold caused by the condensation from the a/c system. This might be possible if they had the car running with the a/c on while running the water. Just a thought

Yeah I'd just say to OP to avoid doing the following:
1. Posting a title in ALL CAPS!
2. Declaring a design flaw with very little evidence.
Pics of the area would be helpful - since other gencoupe owners could simply tell you if something is missing. I know when I was running my tiburon I found out about 2-3 years into ownership that the factory simply did not put in a cabin air filter... just forgot. sometimes parts get missed, and it could be that yours didn't get a certain part. In fact check the manufacture dates of the other car - maybe someone on the assembly line had a day off. LOL
There are many members that are using rubber floor mats who have seen significant rainfall and never complained. There are also GC owners that have had leaky sun-roofs and trunks leak. Most of these problems could be considered build quality issues - but many of us haven't had these problems.
In the end - make the dealer figure out why it leaks - they owe you that.

Yours doesn't have the automated water sensing roll-up windows feature?

Over 12k miles and no leaks anywhere. My car is only washed by hand. It is sitting out in the parking lot at work now under a pouring rain. I also have all weather mats installed so if there were any leakage I would see it. I don't think this is a design flaw, but either a minor manufacturing defect or clogged drain line as already stated. I remember having a drain line clog up on my Stealth. I investigated it and cleared it. Damn Mitsubishi! Why they did not consider Fall foliage debris in their design is beyond me.
There is another thread active on why you hate your Gen Coupe.
Actually, run your A/C for awhile and park your car. If you do not have a nice puddle of water under your car you have a clogged A/C drain line. If you do then keep looking.
