This is my new '13 coupe. Having a blast with my first Corvette.
I noticed an area where the hatch joins the side of the car, doesnt seem perfectly flush like on the other side. Its not very noticeable unless you crouch down to get at eye level with it, Not sure if the dealer could do anything about it anyways... Have you seen this same thing on your vette?
Given that it's a Chevrolet, I've learned that when I "crouch and examine", I find stuff, lol. I've noticed the common fit issue on the front bumper seam, outer headlight area, where it joins the engine lid. Other complaints on this Forum about interior gap irregularities between the dash and the "A" pillar. None of this bothers me anymore because, overall, I love the car so much. Sounds like your issue is an easy fix. Congrats on your new car.
"New" car under full warranty, why not let the dealer check it out and have their body guy make adjustments to the deck lid. Also gives you a record if the problem pops up again, pardon the pun or there is more involved than meets the eye.
Interesting. I just bought a 2013 GS coupe and have the same issue. However, after adjusting the "rubber thingys" I haven't seen any difference. Both of the rear ones are adjusted all the way in now. Am I missing something?
