Rattle when while accelerating

[justsaynototurbos]

I drive a 2021 1500 Rebel with etorque. Only about 20K miles. I have noticed r rattle...sounds like from the right side. When I accurate from a stop or if I really hammer down to pass someone. It stops as soon as I just maintain speed as far as I can tell. I started noticing it about a year ago but it's a little worse now.

I work from home so don't drive a ton...mostly road trips. Which is probably why it hasn't driven me crazy.

Anyone else experience this?

Check the exhaust system: Heat shields, flanges, and hangers to start.

Could be spark knock.
What fuel do you use?
