2022 Chevrolet Colorado

I purchased a new 2022 Chevy Colorado LT in January. When driving home and it got dark I used the dimmer to see better. When using the dimmer all of the radio dials turn completely off / dark (not illuminated at all). I drove off the road, looking down trying to find them. I notified the dealership the next day. They had the vehicle for about a week and told me it was fixed. I went to pick it up but it was not. They kept it, tried to fix it again then stated it is how it is supposed to be. I opened a case with GM. They assured me it would be fixed. I brought it to another dealership. They replaced the radio and told me it was fixed and it was not. They took the truck in again for a week. This is now 3 times the truck has been in. Everyone (dealership and GM) telling me it is not right and should be fixed. They are now telling me it is operating as designed. They are saying there is nothing else they can do under the warranty. It is absolutely ridiculous. The radio dials are not illuminated at night if you use the dimmer at all. This issue is specific to all LT Colorado models The Z71 Colorado General Motors Corporation 100 Renaissance Center, P.O.

The Z71 Colorado model radio (which is identical) does not do this. I requested they used this radio as it is the same (just a different part number). They are stating they need a GM Supervisor or Engineer approval. GM has tried to fix this issue 3-4 times and had my truck for almost 30 days and is now refusing to fix it.
