2008 Saturn Vue white exhaust vapor

[wwhite5799]

I have a 2008 Saturn Vue with only 90,000 miles on it. It runs great and I have not had any issues with it, but on really cold mornings it seems to produce a very thick white vapor for the first 10 - 15 seconds of the first cold start of the day. Its happened the last 2 winters I've not had any issues with it and I take to the dealership regularly for maintenance etc. Just was wondering if someone could help me understand what this is. I've never seen a vehicle do this before so hoping maybe someone can provide a clue. Just start out by also saying this thing doesn't leak any fluids.

Condensation in the exhaust will cause a fog. Your pic shows heavy fog. Perhaps your dealer can help better. At what temperature was the pic taken?

Normal. Once the exhaust system heats up, overnight condensation boils away and exhausts as steam. Heavy steam on cold startup but less after the engine warms up as you described. After the engine warms up and boils remaining exhaust system condensation, a trail of white smoke may be seen because fresh air with moisture is turning into steam. More steam in cold weather due to more humidity. If you insist this isn't so then be prepared for misinformation and misleading suggestions for various repairs to correct it only to find out your wallet was emptied and no solution fixed this issue occurring to every fossil fueled engine.

Thanks I appreciate that. I do think everything is fine just had never seen it before. The thing runs fine doesn't throw any codes etc and not leaking any fluids.

Picture was taken at probably like 30 degrees.
