Normal to see exhaust on start up?

I have a 2020 crewmax sr5 with 35,000 miles on it. I’m sure my situation isn’t new to anyone I just haven’t really noticed it before in this vehicle like I have older 180,000 plus mile vehicles. Anyhow, when I start up my tundra after sitting overnight, I noticed about 20 or so seconds of visible exhaust steam. I thought this only happened on cool or cold days but I have seen it on warm mornings especially after it has rained. It only lasts maybe 20 seconds or so and is not a thick smoke. Has anyone else noticed this and is it normal?

 

I had this happen on my 18. It was accompanied with a rough idle for the duration of the smoke/steam. It turned out to be a faulty alcohol sensor associated with the fuel pump.
Edit: also I was around 36k miles and worried it wouldn't be under warranty. Apparently this fell under the 80k warranty, so they fixed it on Toyota dime.

 

white smoke for short time ok....just moisture burning off as the exhaust heats up.

 

It all depends on the outdoor temperature and humidity. Exhaust gas has a high moisture content and relative humidity since water vapor is a combustion byproduct. This means the dewpoint is also very high (over 120 degrees). The moisture is easy to see in the form of water vapor until the exhaust gas and exhaust pipe heats up to above the dewpoint.

 

This makes me feel a little better. I’m going to try to keep an eye on other peoples vehicles when leaving work in the morning after sitting overnight and see if I notice theirs doing it as well. I certainly expect it when it is cold out and on a cold start, just never noticed it really until recently but, it has been raining a lot lately and super humid outside. Thanks everyone

 

hydrocarbon + oxygen = H20 + co2. Exhaust gas has lots of water vapor. If the exhaust system's not very warm and gases come out of the tailpipe into some wet cool air, poof it makes a cloud.

You should see what a flex fuel engine running E85 looks like on a cool morning. Holy ballsacks. The tailpipe fog for the first couple miles can be so massive the car following behind disappears like the Black Pearl.

 

I don’t get a cloud at all, but I’ve noticed on my 2020, since new, that it spits a good bit of water out the exhaust on startup. Never had another vehicle do it quite like this. Makes little spit zones for a yard or so from the exhaust while I open and close my gate. If I walk by too close, I’ll get my slacks all wet.
