2018 Lexus 350--why does the screen fade from bright colors to not so bright in a brand new vehicle?

 

If you have the top down and the sun is pretty bright, That's just the way it is - unfortunately.

Otherwise, being a new car, take it to the dealer and have them look at it.

 

Err . . . something not quite right here.

If it's a 2018 model it's unlikely to be an IS-C. Me thinks he's in the wrong forum.

If I'm totally wrong and Lexus are still building the IS-C I'll order a new one tomorrow.
