Cracks on black glass trunk trim

[Briboynyc]

So I’ve noticed stress cracks all along the black glass trim that sits just above the lower struck and below trunk release. It runs the entire length of the trim from fender to fender. Look in photo bottom part of black glass trim it looks “ white” and its hairline cracks with the biggest cracks on the curved glass nearest trunk release.

Dealership said it’s damage and something hit it. How does something hit it from behind? And if something didn’t hit it how would the crack run the entire length of the trim piece fender to fender? Looks like Porsche is trying to get away from responsibility?
since it runs entire length I think it’s stress cracks.

Anyone else experience this?

Those are not stress cracks if you mean internal stress from assembly or manfacture. That's surface impact damage, and it very clearly does not run continuously along the entire length. There are big gaps where it skips over, and that right angle near the reverse camera is a telltale sign that someone put pressure on the edge.

Not saying you did it, but it's not a manufacturing defect if that's your belief. If it were, it would've been present at delivery. It looks like someone or something pushed downward on it, maybe while leaning against the car, or a garage door?

Agree. That trim piece is not under any load. It looks like some external force pressed on it

Since our hatch doors open way behind the end of the car when opening, was it parked too close to the garage door when it was opening? If so, when the car sensed that impact pressure it might have returned it to a closed position.

Definitely not a garage or rear impact. Car is parked outside. Never saw the cracks until on day when i went to trunk and saw the cracks

If you ever parked your car in a public place, possible that someone nosed into your trunk area in a parking lot?

Thing is I don’t drive the car often and in back into my spot so I always walk past the trunk to get to the drivers door

Somebody dropped or swiped something against the trim piece. It's the exposed edge for something to fall on it from above, and you can see in the second photo the chips in the plastic and the impression they made on the paint underneath when snapping off. The dust/pollen shows a rightward and downward impact--the scratches are only along the edge because it's the high point.

Looks pretty much like it got scraped by a garden tool handle, 2x4, hockey stick, or something along those lines. Are you near a park or somewhere landscapers work?

Luckily, very little paint damage--I only see a minor clearcoat scratch. Unluckily, I doubt that's a cheap part to replace. It could probably be smoothed out and polished by someone who knows what they're doing.

OP - it’s definitely a defect in the glass of the light bar trim. My wife’s EV has it & we’re taking it to the dealer tomorrow morning to have it evaluated & order parts under warranty. It’s a known defect apparently & has been happening on early production cars. It is not caused from impact, they believe it is the glass cycling cold & hot through ambient temperatures.

It's plastic, not glass. Delamination of defective plastic is possible, but doesn't explain the pollen/dust being disturbed or the light paint scratching underneath the trim where it chipped. Something physical had to cause those.

Plastic… glass…. Doesn’t matter… It’s a defect & looks like cheap clear garbage. Porsche needs to correct it.

Since it’s glass it cannot be polished out (unless someone knows of a way). The cracks are throughout and the white in the photos are the hairline cracks along the edges.

can you share photos of your trim piece? Did you have to open a case with Porsche USA? Sent photos to champion Porsche which is the largest dealership in the country and they said this isn’t a warranty issue. Any assistance would be appreciated

Pollen it just pollen I should have wiped it down before the photo. There is 100% no scratching of the paint other than swirling from dealership prep of the car when delivered to me

It's NOT glass. It's plastic. It's not cracking from heating and cooling and no one from Porsche who knows anything would say so. It might be delaminating from a molding defect, but again, delaminating plastic does not put swipe marks on surface dust above the scratches/scrapes or imprint marks on the dust below it.

It's not the pollen--it's the fact that you're saying there was nothing touching the car when obviously something touched the car to swipe the pollen away and push it into little ripples under the trim piece where it's externally chipped from the top down in the second photo.

If the defect were just inside the plastic and nothing had touched that area, the pollen would still be evenly distributed like it is everywhere else. That's what shows something brushed or hit that area and why you're having a hard time getting a warranty claim.

If there are other cars delaminating on this particular part due to a bad production run, that will help your claim with Porsche.

I responded on this thread. Good luck to all of you.

Can you post a photo here of what yours looks like?

well yes I used my tshirt to move the dust off the trim piece so yes it was “touched” and pushed away.

Thats why I’m trying to find others that have the same issue and found one on the macan EV forum but the more I find others like this the more it supports my case
