I have noticed that both times it has rained very hard so I think the water is getting in through the gas cap. I think this is true because my gas level was almost empty when it rained and my car didn't start. Is this possible? Has anyone heard of any faulty gas caps on the Versa?
I'm not inclined to blame the gas cap. The gas cap is inside a panel out of the direct path of the rain, and the little inset compartment would have to fill up quite a bit before water could enter the tank through a faulty cap seal.
There's a slightly higher possibility that there's a hole in the gas tank itself. Water could be entering the tank from splashing up from the ground. However, you're not likely to get THAT much water into the tank this way, and you should be smelling gas when you're around the car.
Water will condense in the fuel tank as the relative humidity and temperature changes. This generally doesn't produce *that* much water, but you live in an area with high humidity, it's possible. However, I live in Seattle and none of my cars has ever had a problem with this. You might consider adding an occasional bottle of "Gas Line De-Icer"; this is alcohol that mixes with the water and lets the engine burn it. It's not the right approach for a large amount of water, though.
My vote for where the water is coming from: The gas station. Their gas caps could be leaking. If the tanks are fairly low when you fill up, you might get a pretty big slug of water.
This happened to me about twenty-five years ago...the gas station had underground tanks, and the filler was in a small compartment inset into the ground. The compartment acted like a funnel, and the gas cap had a bad gasket.
My engine quit about twenty minutes after I filled up. It really caught my attention, because it was my airplane's engine that was trying to run on water....
My guess is that either the gas stations you went to had something screwy in their systems, or the truck making deliveries had contaminated fuel. I'd ask around at the local auto repair places to see if there's been a big jump in fuel-contamination repairs lately.
