So I'm leasing a 2020 Chevy equinox and I've been having issues with stuttering and white smoke. I took it back to the dealership and of course there was nothing wrong. It wasn't showing any codes and no white smoke no problem when the tech drove it. I noticed the white smoke when I let it run for more than 5 minutes. My brother-in-law said he had the same problem with a Malibu and it was a loose oil pan does this seem plausible. If so how?

 

I will be the first to tell you I don't know all the answers, but I have some serious reservations about a loose oil pan producing anything but an oil leak. Kinda sounds like a "blinker fluid" explanation.

If anything there may be a service bulletin to cover this. What if another dealership were to check this out?

 

Welcome from Florida. Is the white smoke coming from the tailpipe or from under the hood or under the car?
