2013 Toyota Prius — windshield replacement created a highway whistle

I wouldn't throw parts yet. If a shop can't duplicate it on the 2013 Toyota Prius, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. If it doesn't change the out-the-door or the repair estimate, it's noise. Happens in gear, not in park, for what that's worth.

I'd want a measurement, not a hunch. Swap the cheap/easy piece first on the 2013 Toyota Prius and see if the fault moves. If the cheap test changes it, stop and reassess. When does it actually happen? Not trying to scare you — just skip the expensive first guess. I'm keeping receipts and dates in one folder.

Log the conditions before you spend. Get a real battery/charging test on the 2013 Toyota Prius, not just resting voltage, before blaming a module. 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. This is from a 2013 Toyota Prius in Washington DC with 100,500 miles. If you share a photo of the worksheet, easier to sanity-check. Climate here is different, so treat that as a local data point. Heat soak after errands is the other window.
