I have a 2017 991.2. 20k miles and the windshield has quite a few small pits in it from air born debris while driving. Many of the miles are city driven. I've never had a car before that this occurred so frequently. Anyone else experience this?

Both of my Porsches and my AMG tend to have much more pitting on the front end, headlights, windshield, etc. than any other car i own.

I suspect it may have to do with the speed these cars are driven at vs. my SUV. What bit of debris that would bounce off of the SUV at 70, is like a tiny bullet hitting when you are going much faster.

Definitely much worse on my Porsches than other non Porsche car I own or have owned in the past, hit with right sunlight and it's just bad.

Cars that are lower put more bits in harms way (windshield, front fascia, headlights, mirrors). Porsche is no worse than anything that’s low.

These cars are lower to the ground so they will collect pits on the windshield vs the front bumper/hood like other cars. I wonder if Porsche uses a little softer glass maybe also (or lighter/thinner depending on the car?). My C7 Z06 had softer glass plus being low to the ground and it pitted like crazy so the 911 isn't alone. Personally, I had Exoshield installed on my windshield to protect it because I like to do road rallys from time to time where you are on backroads for 5-6 hours in a pack with other cars that also have sticky tires and will throw tons of rocks at you at high speeds. So far, the Exoshield takes all the pits and even really big rocks without issue and no windshield cracks or pits underneath. Something like that could be an option for you...

Yes I have noticed the same thing also on my 2017 991.2 with 23K miles.

You should see what mine looks like at 57...

The plan will be to replace at some point and then protect with an exoshield like product. $1800 installed for glass was the price I was given by one of the better independent glass shops in the area.

Yeah. I have to replace my windshield on my 2017 C2S it's gotten that bad.

On my second windshield as the extreme pitting was annoying to drive in the sun. OEM replacement 2 years ago already showing pitting but I do drive my car daily here in sunny SW Florida. Have had a bunch of 911’s all the windshields seemed prone to this issue.

Seems to me that the core problem is the Porsche windshield is too easily pitted, and this problem is further amplified by the low ride height. Porsche needs to correct the manufacture of these windshields. What year(s) are the most prone to damage? It's the many small chips that is the damage as the glass is too soft. I don't have any protective paint coatings on my car. I have one very small paint chip on the front of my car, no other paint chip damage, all the while getting more and more windshield pitting damage. I've never had this happen in any other brand car I've owned. In other cars a large impact would require windshield replacement, but at that time there were no multiple small impact pits. The cost of replacing a front windshield with sensor calibration is + $2000! Porsche needs to address this problem.

Same pitting here on my ‘13 C2S, 30k miles…anyone tried a polish procedure on the glass?

I actually clay bar'd mine the other day and it did seem to help a bit to fully strip it and get as much of the grime off as possible.

I had a BMW 330 cab (also low to the ground) that did the same thing. My 997 did it. My 991 did it. I had the windshields replaced under a comprehensive insurance claim. No questions asked. No deductible. No surcharge. If visibility is hampered, it is considered a safety issue and therefore covered. This was in MA. Other states may differ. I would inquire with your insurance company before just paying out of pocket.

Unfortunately, windshields are a wear item.

I just wait until I get a rock crack or serious chip and then my comprehensive insurance covers a new Porsche OEM windshield no questions asked $250 deductible. Clearly a comprehensive insurance item.
