One small detail I need to ask the other C7 drivers is how their rear hatch operates? With my C6 you just closed it enough to grab and the unit would gently pull it closed.

With the C7 I have to literally slam it shut. I'm wondering if it's a glitch with the high tech electrical wiring (non motor) closing unit? Anyone else experienced this??

I was going to start this thread a few weeks ago myself. My C6 was electronic as we'll. I'm pretty confident the C7 isn't. Sucks I know.

There is no glitch, but the "vent" does not work as well as advertised...one GM person said the trunks close easier as the seals get more pliable with age, I suppose there is a bit of truth to that...

I had a chance to play with this over the weekend on a car in a showroom (yes, they let me open and close it, it's not a customer car) and it's really not that bad. It's not so much of a slam as a forceful close. If you push the lid down from say 1' it closes fine, if you drop it from 1' it doesn't. If you pull it down from the recessed notch on the lip it closes fine every time. If it doesn't close completely on the first try pushing it down at the latch point is pretty hard, I don't think I would do a lot of that since it's a composite material and I can see stress being an issue.

The effort isn't evacuating the air as much as compressing the huge seal running the entire opening so I can see how it would become easier over time as that seal loosens up and I think the venting they designed is working as advertised.

Good points all -- I just remember pre-introduciton that the C7 team was making a big deal about a new technology that used a wire and electrical current instead of an active motor to do something. I thought that was on the rear hatch lid. I'm going to do some digging. That's really the only thing on the car that would have a closure mechanism like that... No big deal either way. Just don't want to write it up if it's working properly.

It's not a rear closure mechanism. it's an exhaust vent behind the bumper cover that opens whenever the hatch is open using a new technology. The open vent allows the trapped air to escape so the hatch can be closed. This was their solution rather than use an auto closer to reduce weight and complexity (and probably cost) and resolve the trapped air issue (which is the only reason the C6 had an auto closer).

I just came back from checking out a stingray. The closing of the hatch was not that difficult. It's not any harder than closing a door.
Too much nickpicking.

 

[Corvettedriver1492]

I close it with the recessed notch on the inside lip. Then I use my forearm and press down lightly to latch fully. Granted it's been sweatshirt weather here and Ive been wearing long sleeve shirts and don't have to worry about skin prints. I can see myself in the future using a microfiber towel to assist with pressing down to fully close.

One way to find out if it's a vent problem or a gasket problem is to try closing the deck lid with a window open. If there is no problem closing it with the window open you know it's a vent problem. Since I don't have mine car yet I can't test it.

Might this video help?

Thanks for posting! Great video!

 

[scottsdaledave]

So I watched the video, tried it few times and still cannot close the rear deck lid fully first time. Have to push down on it with a palm. Not a big deal, may improve over time.

 

[Sinner]

I just close it forcefully... Kinda slam it. To me it just feels like gaskets are stiff.

 

[Redc7]

I closed one today, just let it drop and then a slight push with my palm, very easy to do. Rather do this than slamming it.

 

[ddelfino]

Doesnt seem to be an issue for me!

 

[gvkooy]

Have problems when everything is closed. Had the top off today and it closed with ease. Would like to know if there is a plan to fix the vent. Seems to be a common GM issue. My Escalade has the same problem with doors.

 

[rbrucemiller]

Yep, I'm having the same problem with the rear hatch. It won't close fully without a lot of force. It closes easily when a door is open. I had the same problem with my C6 until the seal ruptured. It worked great after that. Not a good solution! I plan to be patient with the C7 for a while, but I do intend to follow up at the time of the first service if it has not become easier to close.

 

[glen e]

IT IS NEW....wait a few thousands miles, the gaskets will flatten...mine closes fine with one hand pulling it down....about 3100 miles on my car....

 

[jsvette]

Most of the time RedHot's (2130 miles) trunk closes without issue. It always closes easily if the roof panel is off.

Appears to be clearly the vent to me. If I have the door open, the hatch closes with very little force, using the handle inside the lid as GM recommends. It closes 100% of the time. Tired again this morning to close it with the door and window closed. Used quite a bit of force on the handle, much more than I use with the door open - it did not fully close. Pressing it down appears logical until you do it! The C7 hatch (like all the panels) is thin-you can see it defect!
However it just requires thinking about how you open the door and hatch. If leaving and getting into the hatch, just leave the door open. Then close it after you open and close the hatch. If getting into the car, just open the door before opening and closing the hatch. Not really much extra effort just some planning, but the sequence makes it work. Maybe the seal will loosen, but that will take some time, if it does! This proves to me the vent is not large enough or not opening enough. Considering the amount of air that needs to be moved, not surprising an open door or window is much better.
