So for the 4wd I've only gone over 55 with it in auto setting in bad weather because it kept fish tailing. I've had other 4wd and awd vehicles and never had this type of sound. As for sensors you mentioned me bumping into stuff and that I wouldn't have these problems if all my driving was on road. So far outside of a couple dirt roads it's been all on roads. I have not run into anything, have not been hit by anything and wash the vehicle frequently so there is nothing that is blocking or damaging the sensors, they just go out randomly and work fine when I turn on the vehicle the next time. Some of the safety tech was fixed with a recall, but the sensors, LKA and BLIS go out sometimes for no reason. Regarding the infotainment, I've had numerous new vehicles with new infotainment systems and have experienced minor bugs with them, but never consistent issues that occur almost every day and again, seemingly at random. They probably could be fixed with updates, but it's been over a year since the vehicle came out and the problems are still there, I'm not feeling confident GM is working on or will come up with a solution. Regardless, I expect some bugs in a new model year vehicle, but not this many and not so frequent and consistently. I think spending as much as these cost, expecting it to work right isnt unreasonable. Sent from my SM-N960U using Tapatalk
