The car had been in the garage all day yesterday. I came home in the evening and did the obligatory lustful walk around, and was greeted with a completely trashed windshield...




The glass spontaneously cracked in multiple places, with no significant temperature change yesterday. The strange part is nothing happened to cause this; no one had been in the garage, and all the glass damage is to the inside pane of the two layers. The outside pane is completely intact.

Anyone else see this on the windshield?

Ouch! That sucks. At least if there was a huge temp change when there could be a plausible reason. There is no excuse for what happened to that windshield. I am in CT and during the winter we can see significant temp changes and my garage is not heated. I wonder what the dealer is going to say?

That's not an acceptable reason though. Car wind shields should be designed to endure these temperature changes.

Agreed. I had hoped since we hadn't heard about this issue in a while that it had been resolved.

ipse dixit

Yeah, esp. with all that winter testing Porsche does with their cars.

I am just curious what has to happen for Porsche to recall/issue stop sale. Given the use case for a GT3, its a matter of time before the front wind shield cracks and shatters and kills/injures the occupants during high speed driving. This lightweight glass issues started with the small triangle rear glasses, then was found on the larger door glass but now I believe this is the third front windshield cracking (at least the third incident that was posted which I read, maybe there are more). I would escalate this with the gov agency that tracks these types of complaints. I wouldnt treat the front windshield cracking as annoyance but more of a safety issue.

I know nothing about 992s, but I do know all windshields are designed to crack, but never shatter.

That’s what happened to my windshield last month. Climate controlled garage (detailers). No one touched the car. Spontaneous crack. When I came to look the guy said Another showed up by the time I got there. I noticed a 3rd that showed up between the last time they looked and my arrival.

When they changed the glass the installer commented that the cracked windshield glass looked like it had already been replaced once and wasn’t installed correctly. Likely at port?

It took almost 3 weeks to get a new windshield.


my cracks were on the INSIDE. You could feel them with your fingernails.

I’m sorry to hear this. Glad it got fixed. I guess the reality is buying cars during Covid will have these types of quality issues due to suppliers not using proper materials/personnel. What I am surprised is Porsche not issuing any recalls and letting cars be in use.

I wonder what the ratio is of windshields cracking on a purely track car vs one driven on the street? Is it possible that this new light weight glass can’t take the slight flex of the chassis when driven on less than perfect surfaces?

George P.

Both mine and the OPs cracked while sitting in a garage.

Dr. G

Understood, but the initial event that started the process may not have occurred while it was sitting there.

Thermal cycling could also do it with high figment tolerances.

I was actually thinking about the same thing that it isnt only a factor of thin glass but thin glass on a car that is very stiff/rigid. Glass probably starts fracturing while driving the car as chassis doesnt flex much and the cracks get worse with temperature fluctuation.

Bummer. Unfortunate that Porsche choose marketing and losing an extra pound over a dependable durable glass they used for previous cars.

I’ve had 3+ hard track days at COTA bouncing over bumps and sausages, mine hasn’t broke (yet).
