So my brand new EX-L with less than 40 miles has a rear diff leak. I had a Ridgeline prior and left a bed mat on the garage floor and when I came in from walking the dog I noticed a drip mark on the matt. I assumed it was residue but after another 35 miles or so there was another drip. I slid under and wiped it off but there was yet another drip mark after a short drive. Now I went on the web and tried to find junkyard pictures of the diff trying to get an idea of where the vents were etc. I must have gone under there 15 times. There case would be "wet" even after a short trip around the block. I thought it was an axle seal but after further investigation it was up high on the case but not on top of the case. Turns out there was a bolt up there with a washer and it was coming from there. Instead of dealing with the dealer and all of the aggravation, I simply put a 12mm socket on it and tightened it with a fair amount of pressure from my thumb only. Just drove about 40 miles, went under, and nice and dry. Hope this is not a sign of things to come, I really like this Passport.
