My rear hatch (2LT Coupe) is pulled down slightly below the height of the rear quarters and bumper cover. All of the others I have seen, are flush. My question is: Is this latch adjustable?
I went to Nahas Chevy in Wildwood, Fl. and they said they are too busy to answer any questions. Thus, I hope someone here will have some insight.
Thanks.
Pull off the weatherstrip and the trunk liner you can adjust the latch up or down by loosening the mounting nuts on the latch. Find a new dealer too thats a pretty lame response from them.

I have never in my life heard anyone say they didn't have time to answer one question.
Thanks for the info, I will give it a try tomorrow.
Was going to wait until first oil change, and let the dealer do it, but I don't trust any of them, at least anywhere near me.
I tried adjusting the latch and was not succesful. I shimmed the catch on the hatch with a couple of black washers and it lined right up.
And maybe I'm a dummy but pulled trunk liner, exposed latch and could not find any bolts that let it move around at all. Appeared to be fixed and not adjustable which makes no sense to me. Any insight would be appreciated.

Seems to me that what controls the resting height of hatch is not the latch, but rather the bump stops. I dont have a Coupe, but my frunk and trunk both have little bump stops that set the height when closed. I attached photos of those. Does the coupe have similar stops on the rear hatch?
I did not attempt to adjust mine - and so I do not know if, or how those bump stops adjust. I will look in the Service Manual, but they really look like maybe you just turn them to raise or lower them.
Update: see post 8. I found instructions for adjustment of the liftgate - looks like maybe something a dealer should do.

Andy,
I looked at the bump stops and they don't seem to be adjustable. I turned them with no effect.
If they are adjustable, I don't want to put more pressure on the trunk lid, especially if the latch can be adjusted.
I have looked at 4 other C8's that don't have this issue. So, I am guessing the latch can be adjusted.
I found the following in the Service Manual about adjusting what they call the liftgate. I found nothing about adjusting bump stops, if they are even there on the coupe. Looks like a job for the dealer to me.
I also tried to find something about latch adjustment. I could not. I found the following about liftgate latch replacement. Often, in many other instructions in this manual, an adjustment procedure, if it is necessary or possible, will be included as a step in the replacement procedure. This particular procedure does not include an adjustment step. It did include a preliminary step "Rear End Trim Cover Panel Replacement" so I included that here. But it also does not have anything about adjustment.
Andy,
Thanks for all the info!
The first 2 are for front/back adj. The third instruction for replacement looks like where any up/down lid adj. would be.
I think this will have to go to dealer.
Thanks again.

Sure! I like looking this stuff up - I learn a lot that way. The first one, called Liftgate Adjustement, does include these words:
"2. Adjust the liftgate in order to obtain an even gap between the liftgate and the quarter outer panel, the tail lamp and rear bumper
fascia and so that the lid is flush with the quarter outer panel, the tail lamp and rear bumper fascia."
So its not just adjusting gaps, but making the lid flush with the quarter panel, tail lamp, and rear bumper facia. I do not see how that works, but that is what it says.

I saw that, but, like you, don't understand how that would work.

I'm not saying that this would correct your problem - I see you indicated that you dont want to put pressure on the lid - but I ran across this in the parts listings while looking up other stuff - apparently those bump stops are adjustable, at least according to the parts list description. The base looks like a coiled plastic spring - I think maybe that base must be turned to install and adjust it. Here is the parts listing - and you can see what it looks like not installed. I think if may be more to provide the correct pressure on the lid so that it pops up enough to open it with your fingers rather than being to adjust the height of the lid when its closed. Someone in another thread had that problem where it would not pop open enough - and fixed it by adjusting these stops.
I took the hold down loop (striker) on the lid off my 2023, and off my 2019 convertible. The 2023 had 1 shim under the hold down loop(striker), the 2019 had 5. I took 2 shims from the 2019, and installed them on the 2023. Lid closes flush with rear bumper cover and quarter panels. That is how the factory does it. Now, I have to get 2 shims from Chevy dealer & problem is solved.
It is part #13584212 fits C7 & C8

Reason: part number

Well over a year ago I followed a poster's recommendation and adjusted the bump stops. My coupe hatch was flush with the fenders BUT when the latch was released it did not pop up very far and was hard to get my fingers in the gap. Poster mentioned adjusting the rear bump stops up that puts upward pressure on the hatch when it's released. I did and that caused the front to be up higher when the latch was released.
I just turned them with a wrench! Frankly think I just turned the hex. They are hex shape for a reason. But not sure. Assume they are adjusted at the factory. Recall adjusting the hood on my C7 by turning the rubber stop so it latched both sides when dropped.
Now that will not affect the latch in the center where perhaps a shim is used.
According to his last post, it did require shims in the hold down loop to get it right. Meaning that adjusting the bump stops is only to insure that the lid does not rattle when closed, and also that it will pop up sufficiently for easy opening.

Yep, installing the shims moves the entire rear of lid up, or down, to get it flush with other body parts. I will check the stops after shims installed. Don't want it loose, or over tight, as to put stress on a fiberglass body part,
Shim the catch on the trunk lid to line it up with fenders. Mark with tap before you start because it also affects the space between your rear fenders. Also, make sure it is all the way forward when you tighten it. If not, it may not spring open as designed.

I installed 2 new shims, as I described above, and it lines up fine, and operates great.
Rear hatch latch height adjustable?
