Weird Startup Noise

[Dubsy]

Can anyone tell me what this clunk sound is when starting my 2020 big horn? Doesnt sound like a hemi tick, but I’ve seen some posts in the past suggest something with brakes?

My 2019 does that, I think it is just a systems check of some sort. It's been doing it for 6 years since I got it new.

Maybe auto lock parking brakes disengaged? I know when I shut mine down, sounds like a space ship when they engage. Mine makes same sound as yours.

That's the antilock brakes doing self tests.

Definitely the brakes doing their self check.

I had a feeling because one of the sounds is similar to when I’m shifting to park. Do you guys think its worth getting checked out at the dealership at all just to be safe? My powertrain warranty is up next month

No. It's working as designed.
