So I had my car up on the lift...and the mechanic who was working on my car noticed that my rear differential cooler lines were leaking....heres a picture I have provided....he says its just seeping so it isn't urgent....I'm almost due for an oil change so I'll bring it to the service adviser's attention when I go in....

I am just wondering if anybody else had this problem before?

 

I believe those to be the AYC lines....I could be wrong but I thought there was a TSB for that.

Regardless, it's a warranty item, take it in
