Default Another Body Fitment Issue

XPEL installer pointed out this paint damage caused by the driver’s side headlamp rubbing up against the paint. He has noticed the same issue on all of the 4 C8s he has wrapped. How is the Chevy Dealership going to fix this?

I looked pretty good at kerbecks tent at carlisle but not up that close. I did immediately notice this though



Just a guess but every C8 there had the front or rear lamps seated ever so slightly in a different place than the other. Has to be the composite panels and the way they are molded and cure. The variance must be greater than things like aluminum or steel. I have no explanation they all sit in the openings a little bit off. This isn't C8 this is back to the C7.

Wow. The XPEL installer sent me a photo of this Excelerate Yellow C8. It was worse than my Artic White.

I have some from my buddy who does ppf as well. One C8 CMG which my other friend sold for $110k he paid msrp for it around 84 iirc, had the front and rear issue. Talk about happy. My buddy was like thank god I didn't keep that car. And it was shopped with one rocker being damaged.



That's the cmg one. I never downloaded the pic of the taillight cutting in but it is on one side.

Second gen with this issue. I don't get it exactly. I would have thought it would be addressed by now..

i can't get the doc to load but this is the text. I guess they haven't seen enough taillight housings digging in to warrant a TSB? which is a good thing. from the text it appears to be assembly error or an issue i'm sure they'll find a solution to if they haven't already?

Front Fender and Fascia Realignment

June 16, 2020Some 2020 Corvettes may have a small paint chip in the front fascia below the headlamp on one or both sides of the vehicle. (Fig. 10) The paint chip may be caused by a mis-positioned fender-to-fascia gap joint.



Fig. 10

The fender and fascia joint fit should be realigned. (Fig. 11, #1) The realignment will reposition the fender and fascia downward and inboard so that the fascia is flush with the fender. After realignment, the paint chip will no longer be visible. (Fig. 11, #2)

Fig. 11

Follow the realignment procedure in Bulletin #20-NA-124. The front tire and wheel assembly, front wheelhouse liner and front wheel opening molding must be removed on the affected side of the vehicle.

After adjusting the fender inboard, the headlamp lens (Fig. 12, #1) will be proud of the fender (Fig. 12, #2) and the fascia tip will install below the headlamp lens. (Fig. 13)

Fig. 12

Fig. 13

Refer to Bulletin #20-NA-124 for complete instructions and additional information.

So that particular tsb specifically points to the bottom portion of the headlight where the bumper and the fender connects. Now that the headlight is positioned away from the area at the factory it has created a new spot where the headlight rubs on the forward top portion of the bumper eventually pulling the paint away. I had the issue on my right side headlight which I noticed when the car only had 5 miles so it only just started to rip up the paint. To prevent the spread I put downward pressure on the headlight and used a small strip of sandpaper to take some material away until I was able to insert a piece of paper between the headlight and bumper without using downward pressure. This was my last case scenario short of removing the bumper or going to the dealer which I didn't want to do.

I couldn't find any good ways to align the headlight itself without removing the bumper which looks to be a pain to remove. I am pleased with the result and you can't see where I sanded unless your nose makes contact with the headlight. My left side headlight has good spacing all around and my fender to bumper alignments are spot on.

it only bothers me because as i anxiously await the announcement and eventual arrival of the C8 Z06 i do NOT want to go through the same BS i went through my my C7 Z06 and the front fender vents digging in that took 2 years to come up with new vents and having to have the fenders painted. i was lucky that i never had the front or rear bumper paint life many suffered from on that car, but my 19 Z06 was built one year ago last week and i haven't driven much. i am hoping that car doesn't do it.. to see this happening on this gen has me concerned it will be a 1 in 5 or 6 cars affected and all different ways, minimal, left right middle and instead of rectifying it? they will just repaint for those who want it. frustrating if you have the car it happens to when they could have just made tolerances a little bit greater (like they did with the C7 Z06 front fender vents, they made them a few mm smaller and put tabs on the back to push the vent out a mm.. but 10s of thousands were already built. they were into 2019 MY before that vent redesign was complete version 3.0).

i hope they find a better way than that resolution in the TSB which sounds like they are only moving the fender to cover up the chipped paint?? they know better i guess?

When I talked to someone that worked at GM internally about the issue (who gave me the TSB), they said they would repaint it and it's not just moving the fender to cover the issue. Since mine is covered in PPF, they wouldn't cover that cost, so I didn't pursue it any further.

me and my friend went through this with our C7 Z06's purchased one week apart built one week apart. both of our cars had the fender vents digging into the paint top and bottom. he also had the fender to fascia paint pop i didn't.. i had ppf he didn't. i had to beg and plead for the dealer to get the shop to airbrush the disaster so i didn't have to deal with mismatched fender to door etc and replace my ppf on top of that. it worked out though.. but it was stressful my first new corvette i went all in on it to have that happen.., sucked. i understand the choice you made. because if they refused to airbrush it? i would have done it all myself and i'm thankful i didn't have to because it wouldn't be perfect and i would always know it was there imperfect. i screw my car up? that's on me.. but don't sell me one like that was the attitude i took. .

Same exact thing happened to my left front fender, where it came in contact with the light housing. I requested the dealer to send me a small bottle of touch up paint, and I'd fill the void, in lieu of them air brushing, or repainting the area. With a metallic finish, which Ceramic Matrix Gray Metallic is, matching the color is too risky.

It's unfortunate that Quality Assurance didn't pick this problem up on last year's initial pre-production run of cars.

up on the initial run of car last year.

Looks like Clarence had this happen to him as well. (6:30 mark).

He also had the "wings" of the fasica sticking up which is common i even had it on my C7 but that is all just crap assembly not lining brackets up correctly and tightening them down so they don't allow them to pop up (must just write that off instead if taking the extra 30 seconds per side to make sure it's properly done on line i guess?)

I am also starting to wonder if it has something to do with temperature after they're built. How many days go by before the fascia is painted installed and then parked outside in freezing temps in winter? His car was built early February.

Mine is a 2nd build week car I picked up 2nd week of March. It was fine up until 900 miles, then chipped.
