Rear brake noise on cold start

Have you experienced rear brake noise on a cold start? After a cold start, if I slowly brake it for a stop sign or slow down, I could feel like the ABS started to work or there is a squakie noise from the rear end. It eventually went off after it was warmed up. I thought it was the THUD or gas tank, and it did not sound the same.

I asked my dealer, they told me it is known and normal since MDX is heavier (than aregular vehicle). The dealer said it is not a THUD, even I printed your TSB and showed to them.

thanks,
