Our nearly new 2010 Hyundai Elantra has been discharging exhaust through the small ports in all of the doors and the hatch. These are the small squares designed to allow water to drain out. Each square has exhaust residue around it, some covering quite a large area. Our dealer’s service manager s…

For the exhaust to get inside or come out anywhere other then the tail pipe it must have a leak. Remember the exhaust includes everything from the engine to the very end of the tailpipe.

I’m with Joseph. With your owner’s manual should be a booklet outlining a process for following up problems beyond the dealer. Follow that. Document everything, requiring specific descriptions of the complaint on the shop order and specific responses from the dealer’s shop. Keep all of your copies.…

Has the dealer contacted Hyundai’s customer service department. They have done an outstanding job dealing with complaints here. And I am very curious about exhaust being identified as exiting from the doors. Exhaust from a properly running engine leaves virtually no residue. But for the sake of your…

Rod made a good point. Are you certain that this is exhaust residue and not residue being washed out the drain holes from a manufacturing process? The “sniffer” would at least confirm or disprove exhaust as the source. By the way, manufacturing residue coming out the drainholes would not be accepta…

Thanks, guys! These are all excellent ideas. I should add that the residue smells and tastes like exhaust. Even the service manager agrees that it is. I’m not sure about manufacturing residue. We first noticed the problem when we got discoloration and residue along the body just behind the rear…

Shooting from the hip, I would have to guess that the car was hauled on a truck, positioned at the top/front position and taking many miles of diesel exhaust. The car left the factory with a “skin” to protect the finish but it would not prevent the particulates from accumulating in the door jams and…

OK, we think that it is NOT exhaust. After much crawling around and pulling panels, it appears to be road grime with a hefty amount of oil/grease, etc. The buildup on hauling makes sense as well. I am now satisfied that we will survive our travels. I will get the dealer to replace a few of the p…

While it may just be something that’s flew up to the areas that’s been near the exhaust, you should really not drive this until they sort out what’s wrong with the car. You never know when you’ll take a deep breath and pass out from CO2 poisoning.
