the screen freezed twice on me since i got it in november, 5900kms.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.
no big deal, turn vehicle off, turn back on, back to normal.
raddles, every vehicle has a rattle. most are just the interior. plastic, window, rear spoiler, stuff in cargo area, etc. nothing to worry about. when you notice it effecting performance or driveability, then start to worry.
