2024 Ford Mustang — buzzing noise only at one engine RPM

I'd want a measurement, not a hunch. If a shop can't duplicate it on the 2024 Ford Mustang, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. Post the numbers (or the code) and people can get more specific. If this is nothing, great. I want that in data.

Ask what changed right before it started. Swap the cheap/easy piece first on the 2024 Ford Mustang and see if the fault moves. That's the branch I'd chase this week. I'd want a dollar figure or a measured spec, not 'should be fine.' A day of patience here is cheaper than a wrong part. I'd rather pay for diagnosis than a second guess-repair.

Log the conditions before you spend. A pressure test beats staring at a dry driveway if the 2024 Ford Mustang is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. On “buzzing noise only at one engine rpm,” that was the fork that mattered for me. This is from a 2024 Ford Mustang in New York with 10,000 miles. Do that first. Climate here is different, so treat that as a local data point. Trying not to diagnose from the couch.

Start with the test that can prove you wrong. A pressure test beats staring at a dry driveway if the 2024 Ford Mustang is losing coolant with no puddle. Save the big job until that test fails. Run the total, not the monthly, before you commit. Not driving it hard until I know more.

If it were in my driveway, if a shop can't duplicate it on the 2024 Ford Mustang, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. If you share a photo of the worksheet, easier to sanity-check. I'll poke at it this weekend.
