NX450Guy, why would you immediately decide to replace the windshield. You have two good options. Contact a few local glass companies, they may agree to repair the crack even with the previous super glue. Or do it yourself, buy a repair kit. Why just throw in the towel so quickly? But by the way, thank you so much for coming on here and warning people. I would have never thought using superglue would keep a glass company for attempting a repair.

Some info I found:
https://www.windshieldexperts.com/bl...ure%20sealants.
If you have a HUD option on your car the windshield will have a reflective coating added in it, I think it's either on the inner surface or built into the film found in the centre core of windshield which provides the safety element so that it wont shatter and send bits of glass all over you in a crash. Now this film encased within the 2 separate laminated panes of glass, if exposed with moisture as in from a small crack, will start the glass to delaminate and make things worse plus harder to see through.
If the crack is not in your line of sight and doesn't bother you I would maybe do a self repair properly with a kit found at any auto parts store. And begin the process of deciding if you want to replace it or not. As with most owners a car is purchased to use not to store, and continuing to drive may or may not make things worse, you never know. I personally had a chip happen in the winter months, drove directly to a glass shop to get a chip repair done that very day it happened. Well, they drove it into the warm shop bay and watched it 'come alive!' and crack all the way across from left to right! Thermal shock on the windshield did it in!
Here in Ontario Canada, most newer policies won't offer free windshield replacements, or may hold you to a $1,000 deductible. In this province we are required to bend over and take it up the you know where, especially with high theft rates as of last few years. My rate has gone up over 20% and I'm 59 with no tickets.
These are probably $20 or less:

Yes, you’re right, @TheCDN recommended Rocky’s Mobile Repair, and they had no problem fixing it, unlike SAFELITE. In fact, the Rock’s guy said it was a smart temp fix to stop a crack from expanding and asked where I got the idea from (multiple sites online). The resin couldn’t get deep enough to make the crack disappear, but it’s good enough to not worry about cracks spreading from it anymore. I’m glad to not be replacing that entire windshield like SAFELITE said I needed to. So problem solved for $175 (house visit) instead of the $1500-$3300 replacement quotes I got. Thanks for the suggestions everyone. Bottom line, superglue can keep the cracks from spreading too far for fixing, but it won’t let your chip “disappear” and SAFELITE won’t touch it. But I’m happy with the outcome.

Yes agree 100% the crack fix stuff has never gotten rid of seeing the crack completely for all of my repairs, but it does certainly prevent further cracking and delamination. Plus with this approach if it's gonna work it does, if the crack is too big well it doesn't and your crack will get worse and you buy a windshield. It's simply good protection, but not 100% bullet proof.

Or, just buy this kit on Amazon. Cheap and I have repaired multiple chips with it. Not perfect, but does the job

1. A new windshield would typically be covered under comprehensive. That should also have a much lower or no deductible (closer to $100 in a lot of cases). We always have our windshields replaced at the dealer - they sub out the actual installation (which is a good thing) but we have State Farm and have never had an issue getting OEM glass covered. I prefer the dealer to do the recalibration - I just trust them more since they have experience with these cars.
2. we’ve never had our premiums go up based on claims for windshield repair. YMMV of course
3. if you have a HUD, yet another reason to get an OEM windshield. Too many posts about other cars having HUD issues with non-OEM. May be different with Lexus but just another reason to strongly consider OEM.
4. If you only have a chip and it hasn’t spread too badly and isn’t in your field of view, a repair kit from Walmart or an auto parts store may be sufficient. I did an emergency repair before a long trip this past winter and it’s been holding fine. Probably more noticeable than Safelite would have done but it’s off to the side and hasn’t bothered me enough to get a replacement.
Whatever you decide, best of luck but you may want to call your insurance and see if the above positives may be available for you too. Sometimes we assume the worst but may find out otherwise just by asking.

Sorry for your experience. Hope it ends well for you. I've never heard of using superglue, but one thing you can do that is harmless and certainly helps is to cover the chip with a piece of waterproof tape until you can get it repaired. Some chip repair places will give you stickers to have on hand for this very purpose. You'll be more likely to see the chip turn into a crack when water gets in the chip and the temperature changes, Especially true if you live in a state that experiences below freezing weather. Good luck!

2 My insurance “may or may not” raise my premiums, they couldn’t tell me definitively.
3. Yes, I would only replace with OEM as I have a HUD. My dealer charges $3300, SAFELITE charges $1500 “IF” they can secure a OEM. They told me they may have to charge a higher price after the TRY and find a OEM at the price point that lets them charge only $1500. They told me it would take at least a week to get back to me on finding a OEM windshield.
4. Next time I might try the repair kit route. Turns out not all repair places feared the superglue like SAFELIGHT who refused to fix it when I told them I used superglue to keep the chip from spreading. A mobile repair recommended on this forum ROCKY’s MOBILE REPAIR in Los Angeles, drilled through it and fixed the chip. It’s very small, out of my field of vision, so I’m happy. He charges $100 if you go to him, $175 if it takes about an hour drive to get to you.
This Forum really comes in handy!
