I got my RS on 12/3- every option. Dont have many miles yet and I took my first real highway trip today and put 120 or so miles on it. No issues with the ride, acceleration, interior, etc. BUT I have already had freezing of the infotainment system and a wierd squeak from somewhere aft of the driver's seat. No similar early quality issues with my last 2 GM leased vehicles so Its a little jarring. Im really surprised by the infotainment issue because the system is used in so many other vehicles.
