The rear door of my 2009 Cube has developed a significant leak. Has anyone else experienced this? I am hoping that replacing the weather stripping will take care of the problem.[/QUOTE
Yes! I have this. My cube flooded under the carpet and soaked the pads against the floor. I didn't even know it was leaking until the smell of it caused me to pull up the pad in the rear of the car. The water made it all the way up to the front seats. It was a nasty situation. I went into a body shop. Insurance covered them looking for the leak point and also completely new floor pads. They discovered that water was leaking through some gaskets on the rear tail lights so they replaced the small gaskets. BUT the leak continued to occur because now I was watching it. I found a thread, maybe on hear, about the rear vents leaking water. There are little flaps on the rear right and left that let air out but are not supposed to let air in. If you stand at the back hatch and look down on the inside you will see the vent grates in the plastic. Just beyond those are the offending vents. The vents are attached through the metal of the car. And water leaks between the metal and the plastic. The fix I read about is not perfect but you might get lucky. I used marine grade silicone (with a caulk gun) and ran a goopy bead around where those vents are seated. I still get some moisture weeping in places so I just cram paper towels down in there to keep an eye on it. It's a terrible design flaw and Nissan turns a blind eye. I otherwise have had no issues with my 2010 cube. Luckily I live in a climate that doesn't see much rain. But when it rains I am on high alert.
The rear door on my 2009 Cube SL leaks horribly (and it's not just the vents). First time I took it through a carwash, soapy water poured in through the rubber "seals" around the door. Luckily, it drains out the back instead of flowing towards the front. Never park with the front end angled down. If it rains, the water will flow into the car, instead of out the back.
