Here it is the reason the GT-R got gutted:
"It's a good thing that Doug at Nissan of Santa Monica is a nice guy and that he's one of the most attentive and knowledgeable service advisors I've run across. I have a feeling I'm going to be seeing a lot of him in the next year with our GT-R.
We had two reasons for bringing in our Nissan this time. The first was pretty benign, the 6,000-mile service was at hand. The second issue was more serious; during our performance testing our GT-R was leaking fuel. Leaking may not be a strong enough word here. Trails of fuel raced from the fuel-door and the smell was overwhelming. There were no warning lights and no noticeable loss of performance. Nothing really except a bunch of gas being ejected from the car. The testing was thankfully finished when the fuel-purge began so we parked it, ate lunch, and then drove it home. On the way home, and for the next few days, the issue did not repeat. That doesn't mean that it never happened, though.
The car is at the Nissan dealership now, we'll let you know when we have an estimated time of delivery. One of the problems with buying cars this new and driving them with the frequency we do is that we're often the first people to encounter problems (we were the first GT-R to be serviced in Santa Monica -- they didn't even have a price in their computer yet for the service when we went for our belated 1,500 mile) and the diagnosis is a learning experience for all involved.
Stay tuned."
And the follow up:
"10-days ago I dropped our GTR off at Nissan of Santa Monica to let them deal with a fuel leak we experienced during some *ahem* spirited driving. Once at the dealer the problem, predictably, could not be repeated and nobody in the GTR program had heard of it. Unlike some other issues we've experienced that the dealer couldn't replicate, Nissan decided to act on our complaint immediately instead of waiting for it to happen again. But as the problem couldn't be duplicated and they have no pool of information on this car from which to draw, they weren't quite sure what they were going to do. After several calls to Nissan brass in the States and Japan a solution was decided upon: Replace everything involved in the fuel / evap system from the driver seat back and ship it back to HQ for analysis. The parts were already in the mail when he called me. The car, they said, would be available the following Wednesday, today.
Well this morning I got another call from our local Nissan shop with more news. When the corporate techs (flown in to diagnose a sick godzilla) were removing the transaxle (!) to replace the fuel tank they noticed some moisture on one of the seals. They wiped it off and road tested the car in an attempt to replicate that leak. No dice. Following precedent set with the fuel system problem, they called HQ and were told to remove the transaxle and ship it back for analysis.
The new gearbox is already en-route, we should have the GTR back on Tuesday unless they decide to replace the engine while they're at it. "
