Thump when braking/slowing

[mateo4012]

Hi, I have a new GX500 Premium (less than 200 miles on it) and have a weird issue:

• When slowing to very low speeds from normal driving, there is a single deep thump (sounds exactly like bass from a speaker)
• This thump typically happens at 12-14mph when slowing down, and is pretty consistent (though it doesn't happen 100% of the time); it's not super-loud, but is noticeable.

I'm thinking it has something to do with the transmission or drive train, but wonder if this is a known issue or anyone has thoughts on what it would be. Thanks!
