I know how to set the auto bright lights with the button on the end of the turn signal handle, but the setting does not stay. I have to reset it every time I drive the car, and I know from previous Lexus this is not right. Any ideas?

 

2023 Luxury model here. I have not had that issue.
What year and model do you have?

 

2026 Luxury. I've had 2023 NX lux and2019 UX lux and both worked correctly.

 

The light showing the auto-high beam setting is only lit when the headlights are on. When they are off, it doesn't show the setting and you can't set it. Try setting it the way you like and then the next time you use the car, manually turn the lights on and see if the auto-high beam is still on.

 

Yep. It doesn't stay on from previous setting.
