So true.

In all seriousness though. Mine did that once last summer on the hottest day. Got in windows were closed up tight, it was an oven inside. That happened on start up. I drove to my next destination a few miles away with the AC on. Parked this time window open a little under the vent visors. When I came back and started the truck again it was normal. I have let the windows open a little like that when it's super hot and it's not happened again.

 

Imagine watching that tape, only to figure out it was recorded the night you were conceived....

 

Meh, I've spanked it to worse

 

Same here on a 2020. Happened once with under 500 miles on the truck. Turned it off, and was back to normal when I started it up again. At 30k miles now and has not happened since.
