I bought my LTZ in July and have noticed it pretty much from day one although it feels like its getting a little worse (or more sloppy) over the past couple weeks. I have about 1600 miles so far and wasnt sure if it was the seat cushion. As much as i try to replicate the movement manually, i cannot and it only does it during cornering and braking/acceleration, but it is extremely aggrevating. Now that i know i'm not the only one, i'll try to find time to take it the dealership and start the process. (Also the rear tailgate has never opened or latched properly, (since it was on the lot new) but who has time to keep taking their new vehicle in for service), so i'll probably just keep slamming the dang thing to get it to close fully until i take vacation to get it fixed. I had taken it in once and was told they agreed it was bad, but couldnt adjust it and it needed time in thier "body shop" to investigate further?
