Personally I would go OEM as OEM parts are, in general, better quality than aftermarket. The couple times I have had to get windshields replaced, I asked about it at the dealer (for that brand of car) and was always told they use an independent shop to do the glass work but use OEM parts. And they have given me the name of the glass shop so I can call them directly and skip the dealer markup on the work.

 

If you have the HUD get OEM for sure. I didn't and my display is now not level and can't be adjusted to make it so.

 

Check your insurance. Mine has preferred installers and requires the installer use OEM glass. And the installer bills the insurance directly so my only out of pocket is the deductible.

 

If you have the Heads Up Display feature then definitely use OEM.

 

i just had this exact thing happen to my 2023 Ioniq 5 Limited AWD last month. I had mine replaced by Safelite. The total cost of the windshield/installation/sensor calibration came out to around $1700. My insurance paid for most of it. Others here are saying that the aftermarket glass messes with the HUD, but mine still looks/works fine. no problems almost a month later.

 

I’ll 3rd that on the OEM if you have HUD… Just had mine replaced due to hail damage by safelite… first time they did non-OEM and they also messed up the rain and auto-lights/dimming sensor so auto lights and wipers didn’t work and HUD was angled with double vision, pretty terrible.

They ended up warranty’ing the OEM replacement and reinstall so they ate the cost, but had I known i would have asked for OEM from the get go, insurance should cover. Alls well with the OEM and HUD, level and crisp again.

 

The windshield of my almost brand new 2025 ionic 5 was hit by a tiny rock and the crack has now migrated from the top of the windshield down about 3 inches and then has proceeded to the left and is making its way all the way over to the left side. Unfortunately, Hyundai has not yet made replacement windshields for this model nor have they sent out the calibration software to auto glass companies. In addition, most car insurance companies require you to use only designated certified repair shops because of the calibration issues. I guess I'll be driving with a cracked windshield for a year or two. Hopefully it won't disintegrate; the repair shop guy I talked to told me that the windshield shouldn't fall apart but the glass in these windshields is significantly thinner than ones in the past which is why they break so easily and that I should expect to have to to replace my windshield every 2 to 3 years. That is definitely a design defect.

 

Yeah, crappy glass. The windshields from previous model years doesn't fit?

 

Not going to look into that; apparently the software to calibrate is also different and that hasn't been released by Hyundai either. Will just drive it until glass is readily available and calibration software also, and hope that even if it cracks all the way across the windshield (it's above my line of sight so it doesn't really impede my viewing and all of the safety features that are triggered by the computer sitting at the top center of the windshield seem to be functioning), it won't fall out. And then I'll just wait

 

Might something like Safelite be an option? I had them repair a chip in the windshield of my old Genesis 3.8. I could still see the mark (mostly because I knew where to look) but the repair stopped the crack spreading or otherwise getting worse. There are probably other companies that offer the same sort of crack repair service, Safelite's just the one I happen to know about.

 

It sounds like hers is beyond the size (dollar bill) of chip repair.

 

The 2025 models don’t look too different from the older Ioniq 5 years. I am surprised that the windshield is not the same.

 

According to the dealer, it is not. In addition, calibration software is different.

 

While the windshield dimensions might be the same, I doubt that the integrated computer embedded in the top center of the glass is. That has all of the forward-viewing driver assistance tech (cruise control-following distance; stay in lane; etc). Dontthink that tech is in earlier cars.

 

Those camera lenses and lane sensors
In that box at top center of windshield is not attached to it. Since it is removed and put back onto the next windshield (by some brackets I think) it requires the recalibration. Otherwise, prev MY windshield should be fine.
All that tech u mention, my '23 has that. I just don't have HUD.

There are no significant changes to the 2025 Hyundai Ioniq 5's windshield itself, as reports indicate the body style and front windshield design remain largely the same. The most significant change related to the windshield is that the optional Head-Up Display (HUD) with augmented reality that projects information onto the windshield is available on the top Limited trim. Additionally, rain-sensing wipers are also exclusive to the Limited model.

Will sell it next year and buy a BMW EV.

 

Good luck, with that.

 

I suggest using the OEM replacement windshield if you have the Heads Up Display. I tried using the Safelite on my 2022 Limited and the display was crooked and could never be adjusted to look any better. I would have had to wait awhile to get the OEM version and have it installed at the approved Auto Body Shop so I took the easier and cheaper option which, was obviously the wrong choice. The car ended up getting totaled in an accident about 6 months later so I ended up getting a 2024 I5 Limited. I did learn my lesson however and would not recommend anything other than the OEM windshield replacement based on my experience.

 

Thanks. Sorry to hear ur car got totaled. Looks like u r ok though?
I did get OEM windshield even though I don't have HUD. I went to the dealer but they just called a mobile glass replacement service they use.
However, when I had to get my passenger front side window replaced due to a small chip turning into a crack across a few months later, I went to Safelite since I was going to pay out of my pocket. The first aftermarket one was so warped that the motor couldn't close the window and there were large gaps between window and weather striping. The second one was a little better but still warped and gaps, so, ended up getting OEM thru insurance (that was almost $880 - for a side window!).
I did have good experience with aftermarket windows thru Safelite in the past for my VWs. They were as good or even better than OEM. Oh well.

 

Can't they drill and fill the end of the crack so that it won't spread further while you wait for the replacement?

 

They do chip repairs if less than size of Dollar bill, otherwise replacement. And it sounds like hers is already larger.

 

I have never heard of anyone attempting this before, nor would I do it.

Listen, the glass has a crack. The window has lost its factory integrity. Drilling holes into the glass could itself cause more cracking and make it worse.

To the OP: OEM certified glass shops order them from the manufacturer or the OEM’s distribution chain. They have glass, otherwise they wouldn’t be on the cars now. I suspect your dealership sucks like most do. Ask other dealerships.

For what it’s worth, the 2025 Ioniq 5 was a mid-cycle refresh, not a redesign. Structural parts don’t usually change, just stylistic changes and tech enhancements. It is very very likely the same glass, and as others have said, the camera system center-top detaches and reattaches. I don’t know enough about calibration process myself to know whether or not something special is needed specifically for 2025, but at the very minimum, a Hyundai dealership should be able to obtain whatever is needed. If it’s just software, it can likely be downloaded and added to whatever the device is that they use to calibrate other vehicles.

But do not drill. That is bad advice

 

Agreed. Thank you.

 

This was a mobile chip repair shop a neighbor ran. He had been at it for years, and said he normally wouldn't repair cracks that large, but it was near the edge and fresh, so it was a judgement call on his part.

 

From the little I remember from my college strength of materials class, drilling a hole at the end of a crack is the way to stop the crack from propagating. Might take a special drill bit to cleanly drill glass though. Maybe with some diamond abrasive for the cutting edge.

 

So the general consensus is this:

• Drilling to fill small chips and cracks is good
• Drilling to attempt to stop a crack could mitigate the risks while waiting for the part
• The OP, unless experienced, should not try doing this themselves and should take it to a professional who knows the proper techniques

I did watch a couple of videos, it looks like it requires very precise drilling to a very precise depth. A YouTube-trained regular joe attempting to hammer through with their Stanley drill will likely make matters worse

 

My first windshield chip repairs I observed (pre 2010 I think) - the tech had a little jig to drill a little hole in tge center to relief stress before filling with resin pressed into the chip with high pressure. Any subsequent chip repairs I witnessed and I asked about drilling a small hole I was told they no longer doing it that way. I can say for sure Safelite doesn't do it any longer.
As for the OPs situation, I would recommend to go to Safelite or any other reputable glass repair service and ask for OEM glass replacement (and if insurance approves they will attempt to get it - if they can't they'll let you know). I'm assuming it will go thru insurance since a chip or crack is not covered by Hyundai warranty.
I think the dealer just doesn't want to deal with it since they don’t do the glass replacement themselves- it's usually outsourced to a 3rd party, but they should be able to do the recalibration (that's how it went when I got mine replaced thru the dealer: 3rd party did the glass replacement at tge dealership and then turned the car over to the dealer for calibration).
