Apparently this is a common problem, mine had a hole in the exact same place as yours, as a temp solution I spliced mine with another piece of rubber hose I found and when I get a chance I will try to replace it myself, I don't think it is a 15 min. job though, it's hard to reach in the back of the eng., I think you have take out the whole microfilter assy. to get better access to the vent hose.
I purchased the new crankvent hose for $20 at the dealer, the new hose is made of a stronger material. Let us know how it goes when you replace it.
