I actually work at a Dealership, in sales, and my new 2022 F150 Tremor 402A just had a similar problem. The instrument cluster went completely black on me while driving on the highway. Quite annoying as all the gauges including speedometer are gone. I had no idea how fast I was driving, but obviously went flow of traffic, so it wasn't that big of a deal. I read a bunch of people said it was towing related? I was towing my boat on the weekend, so maybe there's a connection there? I wasn't at the time this just happened though. I'm on holidays for a couple days but will talk to our shop foreman when back and see what they say. I do all our ordering and have never heard of this issue yet. Granted, Tremors are hard to get so we haven't delivered too many. I'll update if I find a solution.....
