HI all, this winter, I started seeing this message up in the high country of Colorado when it was fairly chilly. Now, it is appearing with regularity in the Denver area. The dealer said they couldn't find any codes. Which seems a bit like bs. Anyone experiencing this? This is on a 21 Yukon XL Denali Duramax but no air ride.

take it back and have them or another dealer scan it while the message is active on the display, that's a body code, not a obd code, has to be read by a higher end tool that can read body codes, if the message is not present there may be nothing in the history either, just depends

Thanks for the tips all. I did take it back last week with the message still on the screen and told them to figure it out. They have ordered some new module and are going to install it on Thursday. I will make sure to show them the technical bulletin as well. Hopefully everything will work out as I'm nearing 30k on Mt. Massive.

So, you did not already make them aware of the technical service bulletin?
