Hi,
Ive had my 13 R/T for about two months now(1200 miles on it), its AWD w/ the V8 and I notice when I back out of my garage, there is a slight rubbing or groaning sound coming from the under the vehicle w/ no brakes applied. When I go forward I do not hear it. Anyone else notice this or know about any known issues? Thanks!

 

Never experienced it...

Abs cycle check?

 

Same issue here, 11 Citadel. Mine sounds RPM related, but it doesn't happen 100% of the time. I haven't gone through them yet, but may want to peek through WK2 TSBs and see if you find anything: http://wk2jeeps.com/wk2_tsb.htm

 

Hmmm.. havent noticed anyone mention this!

 

I get weird grinding noises now and again, particularly on tight slow turns. Someone recently posted an update that fixes an issue with the hill hold when pointed uphill and making a tight turn- exactly one of my scenarios. So I tried turning off hill hold and sure enough the problem stopped. But I like hill hold, so I'll go for the update in a few weeks hen I go in for service.

 

How long do you hear the sound?

 

My go to for this kind of issue is put her up on 4 jacks and have an assistant place the car in reverse and try to pinpoint the sound. Does it happen consistently? Does it go away after a few seconds or when you reach a certain mph. Listen to your transfer case with an automotive stethoscope. Front /Rear brakes still biting? Hard to tell but when you get it in the air it makes it a heck of alot easier to pinpoint without getting run over!
