Low frequency rumble

[kgaler]

Hi all, just got the 2020 ST on Friday and so far so good. I have been noticing a very low frequency audible rumble that I wish wasn't there. It seems to resonate in the cabin. It's not consistent and I can't tell where it's coming from. Maybe the tires or the exhaust. Anybody else notice that?
TIA

Interesting... I'm getting ready to buy and did a few exploratory test drives. I experienced what I think you describe.... I'm coming from a BMW 535i... so assume this is just a result of a far less insulated cabin...

I've had mine about 6 weeks and I've heard it only 2 or 3 times , when I'm on gravel , rough driveway , or very rough street in town. Only times I've heard it ,and not every time.

Sounds like the exhaust pipe is ever so slightly bumping against something.

Gonna have dealer take a look in couple weeks while in for oil change.

I'm starting to think it's a drone from the exhaust.

If it sounds anything like a dog growling inside a tin can (best description I could give mine when the advisor asked), watch to see if it’s happening during deceleration when it is downshifting and the engine RPM spikes a little bit. That’s what mine was doing, and the TSB regarding the hose clamp on the flex pipe mostly solved the issue.

It's more like a distant rolling thunder. I noticed that the tires are overfilled from the dealer. 36lbs. I'll fix that with fingers crossed.
