Haven’t ever noticed before but tonight after driving, I went back out to my Suburban and noticed the steering wheel controls were still lit. Also the blue and red around the thermostat was also still lit along with the rear control screen had a back light as well. I’ve done everything to try and get this to turn off. What could be wrong? Or anyone else having this issue?

 

Don't those lights go off by themselves after a certain time frame?

2021 must still be under GM warranty....

 

When all else fails read the manual. Seems to be normal in Terrains and Equinox's that some back lights stay on for 10 minutes.
Still under the 3/36 warranty, then take it into service.

 

Go back after 20 minutes. It they're still on, then you have a problem.
