Another lightweight glass broken - quarter panel
 

Apologies this is another redundant thread, but I wanted to get it in the pool to support as evidence for others as they lodge warranty claims on this lightweight glass fragility defect.

Today I closed my drivers side door and the rear quarter panel glass broke into a bunch of splintered pieces. The glass looks to still be water tight but obviously needs to be replaced. Still driving in the meantime!

reached out to my dealer, and they committed to handling it for me. Cost just for the glass piece is $2,000.

I didn’t need to provide evidence in this case yet, but if I do, Rennlist will really come in handy, so thanks all for posting. Will keep you posted on the resolution.

Sorry to hear this is so common, but glad to hear your dealer is handling it the right way.

$2k for a small pane of glass?!? Ridiculous. Porsche seems to going for Pagani pricing on these spare parts.

Yikes, I wonder if these occurrences have to do with temperature fluctuations, although I've seen the question asked on the previous threads.

Here in Arizona glass coverage is essential (rock chips to windshields are extremely common, USAA and Safeflite Auto Glass are preprogrammed into my phone). I need to check if they provide all around glass coverage outside of the windshield. My SA at my dealership is amazing, I just wonder once it's past the warranty period years from now.

Indeed, it is COMMON, meaning Porsche needs to head on back to normal glass used in your normal C2S for windshield, doors, and quarter panel windows. End of story. Leave the rear window lightweight.

My PDI broken windshield was replaced today. I feared all kinds of new cuts and bruises elsewhere on the car because of the work, but it was quite nicely done by the service department.
They even used tape to match my seatbelts so it won't fly off again before I take delivery ;-) Could be a new CXX option...

here in Santa Barbara, it’s 72 degrees everyday lol…I don’t think it’s temperature fluctuation for me.

still drives fine 😂 and they are handling it for me 🙌 all fair

love that! Good problems to have. We are very fortunate.

Resolution: Porsche said the lightweight glass is actually not the issue. I.e. the speculation surrounding the fragility of the glass compound they say is misguided.
Porsche says, the glass could have been installed misaligned and therefore, something with the door caused it to shatter.

I do not believe this, personally, because others have broken windshields. Just sounds like nonsense. But, Porsche is replacing the glass free of charge. I wasn’t even asked to explain, so good on them.. no harm, no foul.

But what are the down time?

Weeks for some, a few days for others…

When i had my windshield replaced the installer made a comment about how the broken one was not seated properly, suggesting it may have been changed once already. This would have happened either at the factory or in Port as i picked up my car the day it got to my dealer. Maybe it was not installed properly at the factory (ie misaligned).

Can't help but saying this, bu what the hell is going on with Porsche quality? This used to be the kind of crap Porsche owners made fun of towards the Italians. Gearbox issues,cracking glass, broken aero parts, interior rattles galore etc. Go and shut the door on a 993 and it sounds like a bloody bank vault, then do it on a 991 or 992, and it sounds like it has a bag of nuts in there! All this crap in the name of either saving weight or cutting costs.

What a joke.

No down time. I'm out ripping with some broken glass, it's purely aesthetic. Still fully shaped, and water tight. It's like using a spider webbed iPhone. haha

Replacement window will get here in June.

wow...strong reaction. I'm guessing you don't have a 992 GT3, as the only people complaining are sitting on the sidelines with zero actual experience to justify their disdain. (i.e. you and chance64 or whatever his name is)
