Equinox EV Thumping Window Noise

[S1NN3R86]

Ok, so I've been hearing this weird thumping noise coming from the driver's side window of my Equinox EV when it's just a little cracked at hwy speeds. After doing some digging, it turns out this is actually pretty common with modern cars because of their sleek; aerodynamic design. It’s something called Helmholtz resonance, where the air flow creates a pressure wave that causes the noise.

If you're dealing with it, try cracking another window just a tiny bit. It can mess with the airflow enough to tone down the thumping.

Anyone else noticing this on their ride?

I totally noticed the same thing and found it pretty frustrating at first! It’s definitely surprising when you hear that thumping, especially since it sounds louder than you’d expect at highway speeds. I found that just cracking a second window, even if it’s just a tiny bit, really helped reduce the sound. It’s one of those quirks with streamlined cars these days, the design that makes it so aerodynamic can also cause this kind of resonance. Glad you brought it up, it’s a great tip for others dealing with it. And thanks for explaining the reason behind it, I didn’t know there was an official name for this!

Haha, seriously, I had no clue it even had a name until I Googled it! It’s kind of like when people get that annoying "whistling" sound from their sunroof being cracked, just the tiniest bit. Anyway, super glad the window trick worked for you too! Totally makes those highway drives way more chill.
