[FH-ZL1]

2021 ZL1 A10, 6k miles that has had the TSB update for the cluster. Yesterday I had the instrument cluster repeatedly go completely dead while driving, 30 seconds to a minute apart. When I had this happen twice before having the TSB done, the analog gauges continued to work and it was a single event both times with an extended time period (weeks) between them. Not this time, it went completely dead as if it had fully lost power. It would go out and then do what appears to be basically it's re-boot sequence. It did this approximately 10 times in a row over 10 minutes or so. A couple of times when it rebooted it had switched the MPH to the trip meter 1/fuel economy screen. The car continues to run normally through all of this.

I pulled into a parking lot, shut the car down, opened the door for a minute or so, restarted the car and it did once more and then not again.

I will go by the dealer today but wanted to ask for thoughts here as well.
