Brakes make sounds when placing into reverse/drive

Since new on 8/8, when I brake and shift into reverse or drive, the brakes make an unpleasant squeaking sound. Kind of like they're holding but slipping. It's fairly loud. I'll probably take to the dealer but many times they seem clueless so wondering if anyone has had this same issue and the can tell me the cause/solution?

Could possibly be the Hill Start Assist (HSA) being automatically applied? It would apply some braking force during the the transition into a gear. I have an older jeep so I don't have HSA but reading about it that is the first thing to come to mind.

The "Chewbacca" sound is common, I'm told. Annoying, but nothing more.

Great replies!

I ran it out to the dealer and they told me it's from a factory protective treatment on the rotors to keep them from rusting while potentially sitting on a dealer lot for months. They took it out and did 3 60-10 hard stops to heat up the rotors and wear off the coating. It's much better now but he did say to do this one or two more times and if it doesn't cease, to bring it in prior to the 12/12 factory warranty on brakes expire.

To anyone else with the same issue, maybe give this a try and report back from time to time, I sure will. Stay tuned!

My 2013 JKU make the sort of groaning noise. This is just the friction material grabbing the brake pads a little as you back out and making things vibrate. I changed my rear pads when they wore out to Wagner Thermoquiet pads and I do not have the noise anymore.

Very common, any moisture including temp. changes during the night produce moisture. The rotors pick up the moisture and actually have a slight rust coating on them. In the AM, you will hear the "moan" when applying your breaks while shifting from Park to Reverse. It's takes a couple stops to remove the coating. I've had it actually after washing the Jeep, I take it around the block and dry everything off. Freedom is correct, it's the movement and the moisture build up on the rotors.
