The other day, I launched at about 6000 rpm and noticed some white smoke coming from under the car near the rear wheels. Is this normal? Is this defect covered under the Nissan warranty? I've never heard of this happening before and thought that since this is the first year for the Roadster, I may have gotten a lemon.

BTW -- I am kidding and living in my own fantasy world, as at 300 miles on the odo, we are still gingerly breaking the girl in.

your problem arises from dumping the clutch to early. at a 7500 redline, you should be at the 7250 mark. make sure the tires are cold and you're wearing flip flops.

I put mine is the gargage for the winter . After 4 weeks i started it up and it blew lots of white smoke. Im told that this is normal if the car sits for a long period of time.'
The battery just bearly started the car . Will have to charge it every 3 weeks to keep it healthy.

When my car starts, it makes a funny mechanical noise that gets louder when I depress the accelerator...

(sorry Oldguy, couldn't resist)

I find it a little sad that you used the words "smoke" and "vapor" in the same thread like they are the same thing. They ain't. It's not smoke, it's water vapor and it happens on all cars. If you're used to driving cars with smaller diameter exhausts, you won't see it as much. It may be just as much vapor, but you won't see it as much.

Sounds like my situation. It understandably make one concerned when all that white smoke billows from the exhausts. I'm glad its not unique to my car and appears to be an logical effect of starting the car when it hasn't been run for many days or weeks, particularly in cold temperatures.

Hate to bring this thread back from the dead... Car has not been started in over a year. I drained the tank, pulled the coil packs, and changed the oil and checked the coolant, had to top off the coolant. I started it and it cranked on the first fire. I let it run for 15 -20 minutes and a lot of white smoke is coming out of the exhaust. It idles fine, and a good bit of water is coming out of the exhaust as it is running. If i rev the car, the car smokes more. Haven't yet driven it on the road since it has sat, but it does have fresh fuel. Should i clean injectors? Sea foam? Any help is appreciated guys.

Hopefully you aren't burning antifreeze...
