None thus far. Everything is pretty smooth and working well. Only thing that’s a little annoying is when you first get it, the truck is set to go to the factory chevy profile (setup home screen, radio stations, truck features and so on) and then has to load my profile each time. You can’t delete the Chevy profile. Sometimes it’s a quick load and you ne er notice, other times a different radio station is on for a split sec, drops out, screen says loading profile, then everything is up and running. Honestly, just a tiny thing that bugs me.
I did notice the steering is super strong and sensitive as I’m getting steering feed back/shake through the wheel at about 40-50mph. Did it with the factory wheels and tires for about 700 miles and then smoothed out. New tires may need to wear in a bit. She turns the 35s at a stand still on and the brakes like nothing. Super nice when backing in my hauler
