I have Lexus IS250 RWD 2006. Suddenly when the weather was hot and in the car was hot Consumption menu appear(like in hybrid models) and then disappear. After 10 min the navigation display shut down and the buttons around.Today everything is working perfect like there is no a problem. What can be the problem and how can I solve it?

 

Sounds like exactly how mine was acting as it was on it's way out. View my video in the link below and confirm. In the video comments, I had points of interest in the vid that pinpoint the issues.

Bottomline, I fixed my issue by replacing the "NAV unit/screen" with a good, used '08 model. Still working good to this day!

 

 

Since summer is coming, it won't be long.
