2021 making noise.

Hi all,
I've got a 2021 tundra that I bought new in October 2021 and it's been making a very faint noise. It happens when the truck has been off and parked (even if only a few minutes). When I start it, it sounds fine, I back up, put it in drive and still seems fine, but then I'll start driving forward and it make a brief sound like maybe half a second where it sounds a little rougher than normal. It's easy to miss as my wife had no idea. I feel like it's always done this but I've tuned into it more recently. Is this normal or what's the deal? Any ideas?

 

That’s your ABS self test. Very normal.

 

Thank you!

 

Ahh yes...the completely normal, yet very annoying ABS clunk.

 

Does it happen at 6mph????? I think its brake system check.

 

6 or 5 mph every time
