I drive a Skyactiv 2013 Mazda 3 2.0 Liter MT 65,000 miles, and recently bought a 2023 CX-5 NA AT bought new, now at 10,000 miles. Over time I noticed pretty much the same noise with the same characteristics in both vehicles. I get to maybe 45 MPH ish, and I hear a whine that slowly raises in pitch with speed.

Both cars drive perfectly normal. Seems unlikely that it’s an issue since both cars do it. I’ve read a post or two where people took their cars to the dealership and they said it was a normal sound that the alternator makes. Interested to see if anyone else experiences this with their car, or has any thoughts on it.

Thanks for reading, love the subreddit everyone!

    Yeah my girlfriend hears it as well.

    Can you elaborate on having my heading checked?

    And I do have tinnitus (been working in the live music industry for a while around a lot of loud noises), but that’s a stable Bb pitch that I’ve been hearing for a decade, and this is something that raises in pitch with speed.
