Have a 13 GHIG bought it uses with 3600 miles. I have had the car for about 6 mos driving normal not hard stuff. 3 days ago found a maybe 6x6 inch puddle under the differential. The fluid was clean and could see the area where the leak was* r8ght at the diff. cover. Took it to dealership and is gettinf worked on. Just asking if this has happend to anyone else. Thanx all.
