I have a 2019 Suburban with less than 50k miles that I've owned for 2 weeks...started it up one day, instrument panel not working. AC blows, bluetooth works, radio works, no gauges working Currently at the dealer and they cant figure out what's wrong with it. Has a warranty. Not the computer, not the installed Kahu crap...nothing on the diagnostic tests Any one had this issue? Suggestions?
