2024 Rivian R1S — windshield replacement created a highway whistle

Ask what changed right before it started. If a shop can't duplicate it on the 2024 Rivian R1S, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. Stop there until you know. Wrote this up on my lunch break.

Intermittent stuff lies if you only catch it once. Two 2024 Rivian R1Ss can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. On “windshield replacement created a highway whistle,” that was the fork that mattered for me. This is from a 2024 Rivian R1S in Salt Lake City with 28,500 miles. A shop burned me once by skipping that step. Only after sitting overnight so far.

OP update: scanned the 2024 Rivian R1S again and still only have the one pending code, no new lights. This is the version I'd tell a friend.

If it were in my driveway, two 2024 Rivian R1Ss can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. This is from a 2024 Rivian R1S in Salt Lake City with 28,500 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' Not trying to scare you — just skip the expensive first guess. Checking again after work.

I'd want a measurement, not a hunch. Write temp, speed, and in-gear vs coast when the 2024 Rivian R1S does it — then decide on parts. If the cheap test changes it, stop and reassess. Run the total, not the monthly, before you commit. I'm keeping receipts and dates in one folder.

Ask what changed right before it started. Swap the cheap/easy piece first on the 2024 Rivian R1S and see if the fault moves. That's the branch I'd chase this week. If they can't show the line item, I assume it's hiding. I'm keeping receipts and dates in one folder.

This is from a 2024 Rivian R1S in Salt Lake City with 28,500 miles. Do that first. I'd rather be boring and correct. I'll poke at it this weekend.

This is usually cheaper to test than to guess. A pressure test beats staring at a dry driveway if the 2024 Rivian R1S is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. That's the whole play. I'll poke at it this weekend.

On “windshield replacement created a highway whistle,” that was the fork that mattered for me. That's the sequence I'd use. I refuse to clear codes until someone else sees them.

Checked the easy stuff on the 2024 Rivian R1S and found one clue worth chasing before I book a shop. I refuse to clear codes until someone else sees them.

Tried a second charger / second scan and the story on the 2024 Rivian R1S didn't change. If the story changes I'll post the new data.

I wouldn't throw parts yet. Loaded-suspension checks on the 2024 Rivian R1S catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. I'd want a dollar figure or a measured spec, not 'should be fine.' I'll poke at it this weekend.

OP update: scanned the 2024 Rivian R1S again and still only have the one pending code, no new lights. If that fails I'll eat the diagnostic fee.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2024 Rivian R1S, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. Happy to compare notes if your setup is different. Might be overthinking it, but I'd rather overthink than overspend.

If it were in my driveway, move a coil or plug on the 2024 Rivian R1S if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. That's the sequence I'd use. Trying not to diagnose from the couch.

I went back under the 2024 Rivian R1S and it only happens after a heat soak, not on a cold start. Happens in gear, not in park, for what that's worth.
