2022 Hummer EV
Same here - I have had trouble with mine as well. Either says "leveling system unavailable" or the rear will go up all the way, but the front only goes up half way. I did get both front and rear up the full way last night, and the only thing I did differently was drive the truck slowly while it was raising vs parked. Not sure if that always makes a difference. Shouldn't require than either way.
