I Live In Arizona, but was on a road trip. I filled up in Yuma at about 5 pm I would say no more then 85 % outside. Everything was ok. No issues. I then headed towards San Diego. I stopped abound 125 ro 150 miles later. In that drive I went from around 800 feet to about 4,000 ft and back down to about 800 feet. Non stop. But remember I took the gas cap off to fill up, so pressure would and does equalize. Remember on the LS when you take the cap off you can hear the sound of the pressure equalizing. All LS'S do this all the time. I then filled up and that is when I had the issue. It was about 72 outside.
Has anyone ever heard of this?
