2022 Genesis GV70 — windshield replacement created a highway whistle — trying to narrow this down

SunBeltOwnerCommunity StarterFeb 17, 20262022 Genesis GV70 3.5TTampa
A windshield was replaced and now there is a whistle around highway speed that did not exist before. Glass looks seated. Any simple way to locate the air leak before taking it back?

I'd want a measurement, not a hunch. If a shop can't duplicate it on the 2022 Genesis GV70, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. I'd want a dollar figure or a measured spec, not 'should be fine.' I'll poke at it this weekend.

Log the conditions before you spend. Move a coil or plug on the 2022 Genesis GV70 if it's cylinder-specific and see whether the code follows. You'll know quickly if you're on the wrong tree. On “windshield replacement created a highway whistle —,” that was the fork that mattered for me. Take it or leave it — that's what I'd do. If your situation is the opposite, ignore me. Not driving it hard until I know more.

Intermittent stuff lies if you only catch it once. Two 2022 Genesis GV70s can feel identical and have different causes, so measure before you copy someone else's repair. If the cheap test changes it, stop and reassess. On “windshield replacement created a highway whistle —,” that was the fork that mattered for me. This is from a 2022 Genesis GV70 in Tampa. Take it or leave it — that's what I'd do. If your situation is the opposite, ignore me. I keep a notes app thread for this now.

Fair point. Counterpoint: Get a real battery/charging test on the 2022 Genesis GV70, not just resting voltage, before blaming a module. That's the branch I'd chase this week. Verbal 'we'll take care of it' is not a plan. No warning lights, which is why I'm documenting it.

Start with the test that can prove you wrong. Capture voltage while the 2022 Genesis GV70 is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. Keep sale price, fees, and rate as three different conversations. I've seen both outcomes, which is why I'd test instead of assume. I'll update if anything new shows up.

Cleared nothing. I want service to see the alert on the 2022 Genesis GV70 first. No warning lights, which is why I'm documenting it.

Ask what changed right before it started. Move a coil or plug on the 2022 Genesis GV70 if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. Time, temperature, and whether it's in gear are the notes that actually help a shop. A day of patience here is cheaper than a wrong part. This is the version I'd tell a friend.

I hear you, though I'd still want a second check. Capture voltage while the 2022 Genesis GV70 is actually failing — after it restarts you've lost the clue. Don't erase codes until someone who can help has seen them. On “windshield replacement created a highway whistle —,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. Only after sitting overnight so far.

This is usually cheaper to test than to guess. A pressure test beats staring at a dry driveway if the 2022 Genesis GV70 is losing coolant with no puddle. That's the branch I'd chase this week. Happy to compare notes if your setup is different. If it repeats twice more I'll book time.

Fair point. Counterpoint: Write temp, speed, and in-gear vs coast when the 2022 Genesis GV70 does it — then decide on parts. You'll know quickly if you're on the wrong tree. Post the numbers (or the code) and people can get more specific. If this is nothing, great. I want that in data.

I wouldn't throw parts yet. Get a real battery/charging test on the 2022 Genesis GV70, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. No need to make it theatrical. Wrote this up on my lunch break.
