HUD dim after windshield replacement

[waz]

I got a new windshield installed by Safelight on my '18 G90 Premium, and now the HUD is so dim as to be unusable in the daytime. The tech said it was an OEM windshield, and the recalibration was completed successfully.

I searched with AI and, although rare, I did find a Reddit about the same issue concerning a BMW.

The consensus was that it's got to be the new windshield glass not being OEM, or a recalibration issue.

I looked at the passenger side lower corner of the new windshield, and there is a Genesis logo, followed by the letters KAC, then DOT 748 AS1 M4.733 underneath that.

Could I beseech someone with a 1st gen G90 to check if that matches their windshield?

I do not have polarized sunglasses, so that's not the issue, and I received a recalibration certificate from Safelight.

Thanks

It may be OEM glass - but it likely is for a different model of car with the same windscreen dimensions that doesn't have HUD (cheaper alternative). HUD ready glass is different than non, and some have an area on the glass that is intended for HUD projection.

I took a quick picture...hopefully you can see it. I have a 2018 G90 V8 AWD....I do notice that it says " HUD" in the print .Does your replacement have that printed?

Thanx for that Warren... yes, the replacement head light does have HUD on the left lower corner

So I'm certain at this point that I have an OEM windshield

Last Saturday the tech for Safelite replaced the windshield, plugged in the car, and recalibrated the camera, radar, etc. with mobile equipment he set up in my garage. This mobile recalibration equipment is apparently new to Safelite, so they don't know it real well

Besides the HUD issue, every 4th or 5th time I start the car, the car starts with the dashboard illumination at its lowest setting, and I have to push the + button on the dash illumination switch to have the dash light up. (Unfortunately, that does not increase the HUD brightness)

So at this point I think the mobile recalibration equipment the tech used has messed with some settings in the computer

Speaking of settings, I have gone thru every setting on the steering wheel scroll wheel, as well as in "Set Up" on the main menu, and it has made no difference

I took the car to Safelite yesterday, and the tech agreed with me that the HUD was not visible when the headlights are on with a light background. He plugged their scanner into the car and messed around for a while and thought he had it fixed, but he didn't

I have an another appointment with Safelite next week, but I get the feeling that they're flying blind, and will eventually give up and say it's not their fault and it's a problem with the car

At night or with the headlights off, I can see the HUD just fine, but in daylight with the headlights on, it's useless. And I always have my headlights on, day or night

Any suggestions what I should do?

Unfortunately

I would say taking it to the dealer sounds like the next step

My HUD display is clear night or day

Sounds like your ambient light sensor is not working, if the dash lights are also dark. It adjusts the brightness of that and the HUD dynamically.

Following on from the above comment, how well are your rain sensing wipers working now? (The ambient light sensor is part of the rain sensor assembly. This is mounted to the windshield, near the rear view mirror.) Also, how about the headlights on the auto setting. Does that work correctly, or do they come on in the day time too?

Mystery solved.

Safelite recalibrated my car again and that cured all of its issues... the HUD is bright again, the rain sensing wipers are working, and all the other subtle malfunctions are gone!

I'm very relieved... I was girding up to do battle with them because several techs I spoke to had already begun denying responsibility for messing my car up and implylng that my car's problems were pre-existing and that I was trying to rip them off

If you're not aware, they have to plug into the car's data port to recalibrate all the sensors, cameras, LIDARs, and other safety systems

The tech who replaced my windshield and tried to calibrate the car did it in my home garage with portable equipment. He had considerable difficulty in getting the gizmos hooked up to the car, and the recalibration failed twice before he said it was successfully completed. It took at least 90 minutes.

They even emailed me Certificate of Successful Recalibration or some such baloney

So after 10 days of them hemming and hawing, I took it to their shop and they ran the recalibration again. It only took them 15 minutes, and now everything is back to normal

So my advice for anyone getting their G90 windshield replaced - save yourself some aggravation and take it to a Safelite shop rather than their portable

BTW: the total cost for replacing the glass and the recalibration was $2600! Erie insurance paid $2300, and my deductable was $300

This is a little off topic, but I can't recommend Erie Insurance highly enough for anyone looking for home and car insurance. The cedar roof on our house in WNC was damaged by Hurricane Helene, and their customer service was exemplary.

We got our 40 square roof and 8 skylights replaced to the tune of $116000, and they never tried to nickle and dime us like so many insurance companies did to people I know whose houses were also damaged by the storm (I'm looking at you, State Farm)

Plus I have shopped for auto insurance many times over the past 30 years, and Erie's rates have always been the lowest by far

Good to hear

Ona related note
Dont many Auto insurance companies offer a no deductible clause on windshield replacements these days?

I feel like I have that...and I am with Safeco
