Hi Everyone, first time posting on the forums!


I purchased my 2023 V6 A10 Camaro a few months back, so far I've only driven it for 600miles.


Since the day I purchased it I noticed some kind of grinding noise , I'm not really sure where the sound is coming from but I suspect it could be either from the transmission or maybe some loose heath shields.


It only happens while on load, around 1400 to 1500 rpm and while accelerating. I tried to reproduce it while on Park or Neutral, and the sound is not there... that makes me believe it has something to do with the transmission.


I was planning on waiting for my first service to take it to the dealership to get checked, but wanted to see if anyone else has heard this sound.



Today I was able to record the sound, added some indications in the video when the sound is heard.





Thanks in advanced,

Happy to be part of this awesome community.

Sounds like the resonator.

Today I stumbled with this post while browsing online.

I think this is what I'm actually hearing, looks like a pinion bearing issue.

here it says only 326 vehicles potentially affected. That's quite a precise number.

Also, it sounds like GM is saying the actual pinion gear is the problem (low core and surface hardness), not the bearing.
It should be easy to eliminate exhaust as a possible source if the car only makes the noise while in gear and moving.
