VegasIS250

So Ive noticed that when i first start up my IS250 there is a little bit of exhaust smoke that comes of the exhaust. I noticed this when i was driving behind as my girlfriend was driving our IS. Its not alot but its enough to get me on the forum and ask...is this experienced by anyone else??

What color is the smoke? If its only like grey smoke it could be only that some condensation formed on the inside of the exhaust and the water burning as the exhaust gets hot. Its more than likely that but if it smells bad forget about my idea and I don't know what else could be wrong with a brand new car.

yeah blue-ish grey like typical exhaust smoke...smells like normal exhaust

Normal if it's wet from condensation or after a car wash. Not normal after several minutes of driving...

it looked like it mostly went away by the time we were out of the development...ill keep an eye on how long the smoke is present.

Ummm by the way i live in Las Vegas....the thought of condensation doesnt really make sense but then again im not an expert. Maybe its dust that is burning off that gets blown up the exhaust? yeah im prob wrong on that one

What temp is the motor when this happens?Normal or cold? If its when its cold then its normal. Factory tune`s the cars to run rich until the motor is up to opearting temp.This causes a fuel smoke black/brownish.

Its just condensation from the engine being cool. I wouldnt worry about it, especially if it only happens when you first start up and then goes away a few minutes after.

VegasIS250

yeah it only happens on a cold start. morning temps are around the mid to high 80s. Thanks for the input guys....ill keep an eye on it. I feel better now.

if the smoke still exist AFTER the engine's warmed up...then you need to take it back to the dealer......
