The SAME thing just happened to me yesterday. I have an '04 G35X. Just when I started the car in the morning to go to work, all three lights come on. The first thing I did was turn the car back off again and turned it back on about 1 minute later. The VDC and SLIP lights went off but the SERVICE ENGINE light stayed on. The first reaction was that the gas cap was not on tight enough since I had filled up the night before. But it was tight. It happened to be that I had an appointment at the dealer for an oil change, so I had them look at this problem too.
The other thing that I was noticing is that the car was getting a bit sluggish on acceleration, going between 2nd and 3rd gears. This was happening over the last month or so. It would almost seem like the "snow" switch was on, but it never was.
It turned out to be a grounding wire fault somewhere between the ECU, the battery, or somewhere under the dash. What they did was they tightened down the ground wires to the ECU, the battery and under the dash, and it solved the problem. The BIG thing was that it took them about 4 hours to do this. But, it resolved both problems. Now the car is acting normally again.
