After driving the Hummer around for a few days, the new suspension update is a huge improvement! It really eliminates a lot of the front-end lift under acceleration.

Has anyone heard if the 24/25 models will get a new infotainment update.? Been watching a couple of reviews saying that the lagging issue is basically gone now on the 26 models. Mine is very slow. My Ford Explorer ST infotainment system is lightning fast compared to the Hummer.
