The instrument cluster in my 2017 GMC Yukon is totally dead. Blank. Has anyone else had this problem?

I haven't heard of it here. I would check fuses, and then if no issue, disconnect the battery for an hour.

Thank you very much. I disconnected the battery for an hour and now have my cluster back. I hope it stays.

Great news!

Please let us know if it goes out again!

This is one of the issues we never had in the olden days, and we'll start seeing more of this as these vehicles age. The more we know here, the more we can help people down the road.
